Answer:
t = 4
Step-by-step explanation:
1. 2*t = 2t
2. 2*1 = 2
3. 2t+2 = 10
4. 10-2 = 8
5. 2t = 8
6. 8/2 = 4
7. t = 4
Answer:
t = 4
Step-by-step explanation:
2(t + 1) = 10
2t + 2 = 10
2t = 10 - 2
2t = 8
t = 8 ÷ 2
t = 4

An object is moving at a speed of 850 miles per hour. Express this speed in meters per minute.
Answer:
it would be 1385
Step-by-step explanation: because 850 miles per hour converted into meter per min would be 22799.04 meters per sec and then u would Find the number in the whole number place 4 and look one place to the right for the rounding digit on the right side of the decimal point 7. Round up if this number is greater than or equal to 5 and round down if it is less than 5
So the answer is 1385
Answer:
22799 meters per minute I don't know how to express
multiply 850 by 26.822 and u should get 22799 well almost
What is the answer and method to find the quotient of 5.25/1.5
Answer: 3.5
Use long division
12х – 5y = — 20
y = x+4
can someone help me find the x and y
Answer:
0 I think because when you plug y in and combine like terms, you get 7x=0
Answer:
(I'm not sure what you're asking but I believe you're asking for the coordinate where they intersect!)
The lines intersect at (0, 4)
Step-by-step explanation:
Question:
12x-5y=-20
y=x+4
1) Simplify the first equation!
12x-5y=-20
Move 12x to the other side (remember when you move numbers to the opposite side of the equation, it makes them negative) to isolate y!
-5y=-20-12x
Divide all numbers by -5 to just get the variable y
y=4+12/5x
2) Solve
I'm going to be solving by substitution since I like this method the best!
y=4+12/5x
y=x+4
1) Set the equations equal to another (you'll be replacing the variable of y for an equation)
x+4 will be replacing y of the other equation
x+4 = 4+12/5x
2) Simplify
Subtract x on both sides
x-x + 4 = 4+ 12/5x-x
4=4+7/5x
Subtract 4 on both sides
0=7/5x
x is equal to 0!
3) Find y
1) Set x equal to 0 in an equation (I'm doing y=x+4 because it's easier!)
y=x+4
y=0+4
2) Simplify
y=4
Answer:
(0, 4)
What is the y-intercept of the line 3x – 4y = 24?
Answer:
-4 becuase when you graph it the y intercepts at -4
Step-by-step explanation:
Answer:
y-intercept: (0,-6)
Step-by-step explanation:
To find the y-intercept of an equation you make x equal to 0 and we get the equation -4y=24 when we solve that equation by dividing by -4 from both sides and we get our y which is -6.
Hope this helps you :)

Which of these inequalities are equivalent to r > -11? Check all that apply.
-r -33
-3r 33
Answer:
the first choice, the third, and the fourth
The inequality which is equal to r>-11 is -3r<33.
What is inequality?Inequality is like an equation but it is expressed in greater than ,less than ,greater than or equal to and less than or equal to form. It also shows a relationship between two or more variables. We can also change sign by putting negative sign in both sides of the sign.
How to find inequality?We have been given inequality as r>-11 and we have to find the appropriate equivalent inequality from the given options.
We can find the inequality by multiplying and changing sign by putting negative sign on both sides of sign.
r>-11
Multiply both sides by 3
3*r>-11*3
3r>-33
Change > sign to < sign.
-3r<-(-33)
-3r<33
Hence the inequality which is equal to r>-11 is -3r<33.

Can someone pls help me I’m really struggling
What is the slope of the linear function?
Answer:
the slope is [tex]\frac{7}{4}[/tex]
Step-by-step explanation:
Given: 4y - 7x = 10; solve y
4y - 7x = 10; add 7x to both sides to isolate the 4y variable
4y = 7x + 10; now divide by 4
y = [tex]\frac{7}{4}[/tex]x + [tex]\frac{10}{4}[/tex]; reduce the fraction
y = [tex]\frac{7}{4}[/tex]x + [tex]\frac{5}{2}[/tex]; the slope is

Roxanne has already jarred 10 liters of jam and will jar an additional 3 liters of jam every
day. How many days does Roxanne need to spend making jam if she wants to jar 16 liters
of jam in all?
Explain please and how to do the equation
Answer:
3
My logic:
so she jars 10 on the first day (that is 1 day) and she wants to jar 16. so if you subtract 10 from 16 you get 6. Now we know she wants to jar 6 more, and if she does 3 every day then you would divide 6 by 3 and get 2. 2+1 is 3, so 3 days. (if you cant chose 3 chose 2 because your teacher might not want yo to count the first day)

1/4 x 2 2/3, what is the product? (In fraction)
Answer:
8/12
Step-by-step explanation:
you want to write out your problem so it is
1/4 * 2 2/3
then you would want to change your 2nd fraction into an improper fraction (i think. i don't remember the correct term)
so you would multiply the denominator by the whole number on the side and then add the numerator to it
2 2/3 would them become 8/3 (you keep the denominator the same through the process)
so then you would multiply
1/4 by 8/3
multiply across and you get 8/12

Three computers just scanned for viruses at the same time. Computer A runs a virus scan every 10 days. Computer B runs a virus scan every 12 days, and Computer C runs a virus scan every 16 days. How long will it be until all the computers run a virus scan at the same time again?
Answer: 240 days.
Step-by-step explanation:
The number of days that it'll will be until all the computers run a virus scan at the same time again will be calculated by solving for the lowest common multiples of the numbers. This will be:
Multiples of 10 = 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200, 210, 220, 230, 240.
Multiples of 12 = 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168, 180, 192, 204, 216, 228, 240
Multiples of 16 = 16, 32, 48, 64, 80, 96, 112, 128, 144, 160, 176, 192, 208, 224, 240
Here, we can see that the least common multiple is 240. Therefore, all the computers will scan at the same time in 240 days.

A shipping company charges a $3 flat fee for a package, plus a fee based on the weight of the package. The company charges $0.75 per pound, plus an additional $0.50 for every pound over 12 pounds. . George plans on sending a package that is over 12 pounds. He has $27 to spend on shipping. What is the maximum number of pounds that this package could be? The Maximum number of pounds is
Answer:
32 pounds
Step-by-step explanation:
$3 flat fee for a package, plus a fee based on the weight of the package. The company charges $0.75 per pound, plus an additional $0.50 for every pound over 12 pounds.
The first step would be to derived an equation
$3 + $0.75
3 + 0.75x
Where x = number of pounds
George plans on sending a package that is over 12 pounds. He has $27 to spend on shipping.
Hence,
3 + 0.75x = 27
0.75x + 3 = 27
0.75x = 27 - 3
0.75x = 24
x = 24/0.75
x = 32 pounds
The maximum number of pounds that this package could be is 32 pounds
