Answer:
$1.50
Step-by-step explanation:
She wants to leave 20% of the cost of her meal as a tip.
So, we simply multiply the cost of her meal by 20%.
![\frac{20}{100} × 7.50](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7B100%7D%20%C3%97%207.50)
That gives us $1.50.
It is an equilateral triangle, so the angles need to add up to 60 degrees each
5y = 60
5y/5= 60/5
y = 12
2x - 4 = 60
2x - 4 (+4) = 60 (+4)
2x = 64
2x/2= 64/2
x = 32
hope this helps (this is assuming it is a equilateral triangle)
Let x be variable and 1/2 as fraction
1/2x =8
Answer:
-20
Step-by-step explanation:
4p^2 + 7q^3
4(-3)^2 + 7(-2)^3
4(9)+7(-8)
36 - 56 = -20
This looks like a regular equation with substitution. so it would be
5(2) + 2(5) + 1
10 + 10 + 1
21.
If theres another way of going about doing this please inform me :]
