7.47/3 = 2.49. 2.49 is the base cost per yard. 2.49*2 is 4.98. The extra fabric will cost him $4.98
Also pro tip always put the unit of measurement in when describing, whether it'd be a dollar sign or other thing.
Look at the right of the number you want to round then if its greater than 5 round the number that you originally wanted to round. Round it up or down. In this number, 0 is less than 5 so 6 stays the same. all the numbers after 6 turn into zeroes.
Your answer is: 2,600
use FOIL (first, outside, inside last)
4a * 3a = 12a²
4a * -8 = -32a
-6 * 3a = -18a
-6 * -8 = 48
-12a² - 32a - 18a + 48
combine like-terms: -12a² -50a + 48
Answer:
3
Step-by-step explanation:
add 8 to both sides then x=3
Answer:
-16x-28
Step-by-step explanation:
Break it into little pieces; start with distributing the -7:
-7(5+x)
-35-7x
Now add the rest of the problem: 7-35-7x-9x
Combine like terms: 7-35 7x-9x
7-35=-28 7x-9x=-16x
Rearrange so the coefficient and variable are upfront, giving you:
-16x-28
