Answer:
- 2x - 31
Step-by-step explanation:
Given
- 3(4x + 5) - 2(- 5x + 8)
Multiply the terms in the first parenthesis by - 3 and the terms in the second parenthesis by - 2
= - 12x - 15 + 10x - 16 ← collect like terms
= (- 12x + 10x) + (- 15 - 16)
= - 2x - 31
Answer:
1.44
Step-by-step explanation:
You are trying to find what's the price per ounce which is the unit rate to find that out you.You first make a fraction then if it's money put it in the numerator ALWAYS and the 7 in the donomenater then make another fraction put 1 in the donomenater since you are trying to find the unit rate then you think 7 divided by what equals 1 and the answer is 7 because 7 divided by 7 equals 1 so now you know what to divide to 10.08 it's 7 so 10.08 divided by 7 equals 1.44.So the price per ounce is $1.44
The answer is 5 because 5x4=20 divided by 100
Volume is defined as area of the base*the hight.
In this question the base is the traingles.
Area of a triangle is base*hight/2, so it 8*6/2= 24
Volume is 24*8(hight)=192
So the answer is 192cm^3
