= 4(x + 2)
= 4 × (x + 2)
= 4 × x + 4 × 2
= 4x + 8
Answer:
Here's what i know:
x + y = 23
3y / 20 =x
Here we can use substitution to help find our answer:
y + 3y/20 = 23
20y/20 + 3y/20 = 23
23y/20 = 23
23y = 23 * 20
y = 23 * 20 / 23
y = 20
x + 20 = 23
x = 3
There are 2 of 5 students that do not eat breakfast. This can be represented as 2/5. To find how many did not eat breakfast, you multiply 2/5 by 2500.
This gives you 1,000.
Therefore, 1,000 students surveyed did not eat breakfast.
Hope this helps!
Answer:
B) n3 + 4n2 + 8n - 16
Step-by-step explanation:
combine 2n3 - n3 = n3
4n2 stays the same
combine -7 - 9 = -16
8n stays the same
n3 + 4n2 + 8n - 16
