Step-by-step explanation:
x=y+9
substitute
3(y+9)+8y=-6
3y+27+8y= -6
13y = -6 -27
13y= -33
y = -33/13
x = -33/13 + 9
A. 1/100 * x = 7
x = 7 * 100/1
x = 700
b. 50/100 * x = 33
x = 33 * 100/50
x = 66
c. 3/100 * 100 = 3
d. x/100 * 200 = 6
2x = 6
x = 3
e. 15/100 * 40 = 6
Answer:
B.
Step-by-step explanation:
You have to use the number in the variable to figure out if the number multiplied by 3.5 goes over 20 dollars. The highest you can go without going over 20 dollars is 5 notebooks
the perimeter is:
4(4x - 6)
Applying distributive property:
4(4x) - 4(6)
16x - 24
Then, the perimeter can also be represented by 16x - 24 because 4(4x - 6) can be simplified to 16x - 24
