Let b represent the distance to the beach from the library.
total distance = (home to library) +(library to beach)
18 miles = 7 miles + b
11 miles = b . . . . . . . . . . subtract 7 miles from both sides of the equation

At the grocery store, apples are one price and chocolate bars are another. mary buys three apples and one chocolate bar for $2.70. bill buys one apple and 4 chocolate bars for $6.40. write a system of equations to model mary's and bill's purchases and then determine the cost of a chocolate bar.
Answer:
Step-by-step explanation:
Step 1 is to collect the information in a table format. The attached Table1 summarizes what we know in columns 1 - 3. Columns 4 - 6 show the data we're about to calculate, so ignore them for the moment.
.I use A for the price of one apple and C for the price of 1 chocolate bar. We know how many of each are purchased by both Mary and Bill, and the total each paid.
The last column (6) shows the price for each, which comes from the derivation presented below.
We can set the information in columns 1 - 3 into equations:
Mary: 3A+1C = 2.70 [This states that Mary bought 3 apples at a price of A for each apple, and 1 chocolate bar at a price of C per bar.]
Bill: 1A + 4C = 6.40 [In the same fashion, this summarizes how Bill parted with his $6.40]
---
Now let's rearrange either equation to solve for C. I'll use Mary's equation:
3A+1C = 2.70
1C = 2.70 - 3A
This tells us that the price of 1 chocolate bar is $2.70 minus the cost of 3 apples. Interesting, but we need the price of a chocolate bar to determine an exact amount.
----
Now take Bill's equation and substitute the value we just derived for the price of a chocolate bar C = (2.70-3A).
1A + 4C = 6.40
1A + 4(2.70 - 3A) = 6.40
1A + 10.80 - 12A = 6.40
-11A = -4.40
A = 0.40 This is the price for 1 apple. This is the value in the last column (6) of attached Table1.
---
Now we can use the value of $0.40 in either equation to find the price of a chocolate bar. I'll use the rearranged equation we developed for Mary:
1C = 2.70 - 3A
1C = 2.70 - 3(0.40) [A = 0.40 from the above work]
1C = 2.70 - 1.20
1C = 1.50
The price of 1 chocolate bar is $1.50. Pricey, and bad for health. But very tasty.
Columns 4 and 5 are the total costs for the apples and bars bought by each, and their sums add up to the amounts we were given at the start of the problem. So our prices must be correct.
Find the measures of angles a=(2x+3) and b=(2x-3),if their sum is 120 degrees
Answer:
angle A is 63 degrees,
angle B is 57 degrees
Step-by-step explanation:
first, let's create the equation. Pretty simple, because angles a and b become 120 degrees when added up, this this will become:
2x+3+2x-3=120
now, we make it simpler. In this case, just add up the numbers that we can add up. this eventually becomes:
4x=120
now, all we need to do is divide 120 by 4, which becomes 30. So, x=30.
substitute the 30 into the x in the original equation, and this becomes:
60+3+60-3=120
63+57=120
thus, angle A is 63 degrees, and angle b is 57 degrees.
Let f(x)=√9x and g(x) = x + 7.

√9(x+7)√9x+63The smallest no for the domain is -63 as square root of a negative no not possible.
For -63
√-63+630Answer:
x = -7
Step-by-step explanation:
[tex]\begin{aligned}f \circ g=f[g(x)] & = \sqrt{9(x+7)}\\& = \sqrt{9}\sqrt{x+7}\\ & = 3\sqrt{x+7}\end{aligned}[/tex]
Domain = input values (x-values)
As we cannot square root a negative number, the domain is:
x ≥ -7 → [-7, ∞)
Therefore, the smallest number that is in the domain of [tex]f \circ g[/tex] is -7

The ratio of Nathan's nickels to dimes to quarters is 4 : 4 : 17.
What is the ratio ?Ratio expresses the relationship between two or more numbers. It shows the number of times that one value is contained within other value(s).
Number of dimes = 1/5 x 40 = 8 Number of nickels = 1/5 x 40 = 8 Number of quarters = 40 - 8 - 8 = 34The ratio = 8 : 8 : 34 = 4 : 4 : 17

wyatt has a square garden. he adds 3 feet to one side and 1 foot to the other and now it is a rectangle with an area of ft^2 what are the new dimensions of the garden
Answer:
The new dimensions are 6 ft and 4 ft.
Step-by-step explanation:
Let x = side of original square.
The sides are increased by 3 ft and 1 ft, so the new side lengths of the rectangle are
x + 3 and x + 1
The area of the rectangle is length × width.
area = (x + 3)(x + 1)
area = x² + 4x + 3
The area is 24 ft².
x² + 4x + 3 = 24
x² + 4x - 21 = 0
(x + 7)(x - 3) = 0
x + 7 = 0 or x - 3 = 0
x = -7 or x = 3
x + 3 = 3 + 3 = 6
x + 1 = 3 + 1 = 4
The new dimensions are 6 ft and 4 ft.

what is 9x7 equal to i been stuck
Answer:
9x7=63
Step-by-step explanation:
just use a calculator for multiplication
The product of 9 and 7 is 63. In other words, the result of multiplying 9 and 7 is 63.
To find the result of multiplying 9 and 7, by follow a step-by-step process.
First, start by writing the multiplication expression as 9 multiplied by 7.
Next, multiply the digit in the ones place of the first number (9) with the digit in the ones place of the second number (7).
In this case, 9 multiplied by 7 equals 63.
Then, move to the tens place of the second number (7) and multiply it with the digit in the ones place of the first number (9).
Since there is no digit in the tens place of the first number, skip this step.
Finally, add the products obtained from the previous steps.
In this case, there is only one product, which is 63.
Therefore, the result of multiplying 9 and 7 is 63.
Multiplication is a fundamental arithmetic operation used to determine the total value when a number is repeated a certain number of times. In this case, multiplying 9 by 7 represents adding nine 7s together.
