Answer:
-2
Step-by-step explanation:
-4(3x – 7) = 52
3x-7= -13
3x= -6
x= -2
1.) 4(x+3)
Find the GCF, Greatest Common Factor, of 4x and 12.
4x=2*2*x
12=3*2*2
The greatest common factor is 4. Put this outside of the parentheses. (You would multiply the 2*2)
Then, put the rest of the factors as a sum. (Only the factors on the same line.)
Solution: 4(x+3)
To check, distribute to see if it works.
4x+12
2.) 2(4r+7)
Find the GCF of 8r and 14
8r=2*2*2*r
14= -1*7*2
The greatest common factor is 2. (There is only 1 two, so you would not multiply them.)
Then, put the rest of the factors as a sum. (Only the factors on the same line.)
Multiply the 2*2*r as one addend and the -1*7 as the other.
Solution: 2(4r-7)
To check, distribute to see if it works.
8r-14
Do you get it now?
3.) 5(x+7)
4.) 7(2x+1)
5.) Cannot be factored.
32x-15
Find the GCF of 32x and -15
32x: 2*2*2*2*2*x
-15: -1*5*3
Because there are no similar factors other than 1, it cannot be factored.
6.) 8(4x+3)
7.) 3(2x-3)
8.) 24(1x+2)
9.) 9(-2x+8)
10.) Cannot be factored
11.) 8(1x+3)
12.) 50(1x+5)
Answer:21
Step-by-step explanation:
One = <AOB
two= <BOC
three = <COD
four = <DOE
five = <EOF
six = <AOC
Seven = <AOD
Eight = <AOE
Nine = <BOD
Ten = < BOE
Eleven = < BOF
Theres a bunch more but im not listing them
Here hope this help the solution is X= -2 and y=9
Kate paid $25.39 for her purchases.
Kate will receive $24.61 in change.
Step-by-step explanation:
Given,
Cost of t-shirt = $12.95
Cost of pair of shorts = $10.95
Total = cost of t-shirt + cost of pair of shorts
Total = 12.95 + 10.95 = $23.90
Sales tax = 6.25% of total amount
Amount of sales tax = 
Amount of sales tax= $1.49
Total amount with sales tax = 23.90 + 1.49 = $25.39
Kate paid $25.39 for her purchases.
Amount paid = $50
Change received = Amount paid - Bill amount
Change received = 50 - 25.39 = $24.61
Kate will receive $24.61 in change.
