Pre-Algebra
Addition Property of Equality - Adding on both sidesSubtraction Property of Equality - Subtracting on both sidesMultiplication Property of Equality - Multiplying on both sidesDivision Property of Equality - Dividing on both sidesTransitive Property - If a = b and b = c, then a = cSymmetric Property - If a = b then b = aStep-by-step explanation:
Step 1: Define
4m + 1 = 7 → 4m = 6
Step 2: Identify
We see that we subtracted on on both sides of the equation. Therefore, we would have to use the Subtraction Property of Equality. Therefore, 2 is our answer.

what’s 6/7 - 1/2? also how do i subtract fractions with unlike denominators? you don’t have to answer the 2nd question
6/7 - 1/2 equals 5/14.
Subtract the fractions: Now that the fractions have the same denominator, you can subtract them by subtracting the numerators while keeping the common denominator. In this case, subtracting 7/14 from 12/14 gives you 5/14.
To subtract fractions with unlike denominators, you need to find a common denominator for both fractions. The common denominator is the least common multiple (LCM) of the denominators. Once you have the common denominator, you can subtract the fractions by following these steps:
Find the LCM of the denominators: In this case, the denominators are 7 and 2. The LCM of 7 and 2 is 14.
Rewrite the fractions with the common denominator: To rewrite 6/7 and 1/2 with a common denominator of 14, you need to multiply both the numerator and denominator of each fraction by a suitable factor. For 6/7, you would multiply both numerator and denominator by 2 to get 12/14. For 1/2, you would multiply both numerator and denominator by 7 to get 7/14.
Subtract the fractions: Now that the fractions have the same denominator, you can subtract them by subtracting the numerators while keeping the common denominator. In this case, subtracting 7/14 from 12/14 gives you 5/14.
Therefore, 6/7 - 1/2 equals 5/14.

Micah and Joel each have a set of five rational numbers. Although their sets are not the same, their sets of numbers have absolute values that are the same. Show an example of what Micah and Joel could have for numbers. Give the sets in order and the absolute values in order.
Solution :
Ordering numbers means we have to arrange the numbers in ascending order or in a descending order i.e. from small value to big or from big value to small value.
The order of the positive numbers is same as the order of the absolute values and their order of the negative numbers are opposite to the order of their absolute values.
In the context, if Micah is having numbers 1, 2, 3, 4, 5, then the order of the absolute values of the numbers would be 1, 2, 3, 4, 5. Similarly, if Joe is having numbers -5, -4, -3, -2, -1, then the order of their absolute value will be also 1, 2, 3, 4, 5.
And if Micah have the numbers -5, -3, -1, 2, 4, then the absolute values of his numbers is 1, 2, 3, 4, 5. Also if Joe have numbers as -4, -2, 1, 3, 5, then his order of absolute values is also 1, 2, 3, 4, 5.
Mackenzie has a loyalty card good for a 20% discount at her local hardware store. What would her total in dollars and cents be, after the discount and before tax, if the total cost of all the items she wants to buy is $17.45? Round to the nearest cent.
Answer: $14.0
Step-by-step explanation:
For us to calculate this question, we have to find 20% of $17.45 and then subtract the value gotten from $17.45. This will be:
= $17.45 - (20% × $17.45)
= $17.45 - (0.2 × $17.45)
= $17.45 - $3.49
= $13.96
= $14.0 to nearest cent

A ratio is a comparison of two quantities. For example, the ratio of cows to pigs on a farm could be 1 to 3. For every 1 cow, there are 3 pigs. The ratio of chocolate chips to raisins in a cookie could be 5 to 9. For every 5 chocolate chips in the cookie, there are 9 raisins. Do you notice a repeating phrase in these examples? “For every” is key ratio language. It tells you how much of one quantity exists in comparison to the other quantity. A ratio consists of just the numbers, not the units. If someone asked the ratio of chocolate chips to raisins in the cookie example, you’d say 5 to 9.

identify the angles that each have a measure of 88
Answer:
∠1=∠88(Vertically Opposite angles are equal)
∠8=∠88(corresponding angles are equal)
∠3=∠88(alternate interior angles are equal
Angles ∠1, ∠3 and ∠8 are equal to 88°.
What is angle?An angle is the formed when two straight lines meet at one point, it is denoted by θ.
Angle 1 and 88 are the vertically opposite angle, so they are equal
∠1 = 88°
Angle 1 and angle 3 are corresponding angle, so they are equal
∠1 = ∠3 = 88°
Angle 3 and 8 angle are vertically opposite angle, so they are equal
∠3 =∠8 = 88°
Therefore, ∠1 = ∠3 = ∠8 = 88°

joe spent $15. he bought 2 cans of oil. abouthow many gallons of gasoline did he buy
The expression that can be used to determine the total amount of Joe spent on gasoline and oil is 2.85g + 3.15c.
The number of gallons of gasoline he bought is 3.0 gallons.
How to find the expression to determine the total amount of gas bought?Joe bought g gallons of gasoline for 2.85 dollars per gallons and c cans of oil 3.15 dollars per can.
Therefore, the expression that can be used to determine the total amount of Joe spent on gasoline and oil is as follows:
total amount = 2.85g + 3.15c
where
g = number of gallons of gasolinec = cans of oilJoe spent 15 dollars . He bought 2 cans of oil . The amount of gallons of gasoline he bought can be calculated as follows:
15 = 2.85g + 2(3.15)
15 = 2.85g + 6.3
15 - 6.3 = 2.85g
8.7 = 2.85g
g = 8.7 / 2.85
g = 3.05263157895
Therefore,
g = 3.0 gallons of gasoline

Mark and his friends order two pizzas of the same size .•The first pizza is cut into 6 slices of equal size .•The second pizza is cut into 4 slices of equal size. Each person plans to take 2 slices of pizza. Mark concludes that he would get more pizza by taking 1 slice from each pizza, instead of 2 slices from the first pizza. Explain why Mark is correct. Be sure to include a number comparison by using > or < in you explanation.
Mark is correct because taking a slice from each pizza would be 3/6 or 1/2 of the pizza but taking two slices of the first pizza, Mark wouldn't get as much because that is the same as 2/6 or 1/3 of the pizza. 1/2 > 1/3 therefore Marks conclusion is correct.

A half game in football is 45 min. At one point, a half was extended so that it was 48 minutes 30 seconds long. By what percentage was the half extended? Round to the full percentage.
Answer:
8%
Step-by-step explanation:
Multiply the number 45 by at least 1 point 0 something and therefore. We can assume that a 5% increase is around 47 minutes and 15 seconds and a 10% increase is around 49 minutes and 30 seconds ranging for you to use from 6% to 9%. The exact answer for the increase is around 7.78%, for me, I would plug in the equation like 45*1.7 and 45*1.8 on the calculator for more accuracy since you would need to round to the full percentage if it's between 7.5% to the exact number, it would be fully rounded to 8% since you would need at least a 5 to round up.

If both x-term for both ordered pairs have same value. The slope for line graph is undefined.
~ Proof ~
Using Rise/Run
[tex]m = \frac{1 - 0}{ - 1 - ( - 1)} \\ m = \frac{1}{ - 1 + 1} \\ m = \frac{1}{0} [/tex]
Because the denominator is 0, therefore, the slope is undefined.
Because from rise/run. We put the x-term to subtract another x-term. And if both x-terms have same value. It will give the run/denominator = 0.
Therefore the answer is a. Undefined

Frederick uses his metal detector to search for coins on the beach. He has found both newer and antique coins. He has found 24 newer coins over the past year, witch is 75% of all the coins he has found. What is the total number of coins he has found?
Answer:
32 coin in allStep-by-step explanation:
Step one:
given data
let the total coins be x
we are given that 75% of x= 24
Step two:
Mathematically we have
75/100*x= 24
0.75x=24
divide both sides by 0.75
x=24/0.75
x=32coins
Hence the total coins is 32
