Answer:
5A. 80
6A. 84
8. 80
12. 130
17. 800
2. 10.5 cm
3. $102
4. 33 cars
5B. Gas: $55.44 Electricity: $76.56
6B. 85%, $17
Step-by-step explanation:
:) I think these are correct! They are in order from each page!
5A: 80*20%=16
6A: 84*50%=42
8: 80*75%=60
12: 130*40%=52
17: The printer costs $160, and 800*20%=160
2: 25% of 84 is 21 so there is 63 cm left. Divide by 6 and you get 10.5
3: 25% of 136 is 34 so he has 136-34 left, or 102
4: 17.5% of 240 is 42 so there are 198 other colors. Divide by 6 you get 33
5B: 42% of 132 is 55.44 if you subtract you get 76.56
6B: 100%-15%=85% and 85% of 20 is 17
Answer:
The addition property of equality
Step-by-step explanation:
2 + 8 = 10
10 = 10
Answer:
c
Step-by-step explanation:
x^2+5x-14
factor by finding multiples of (-14) that add up to 5
7*-2=-14
7+-2=5
So the factored out equation is (x+7)(x-2)
Therefore the solutions are x=-7 and x=2
In order to solve this we need to get x by itself on one side.
We need o start by adding across the 4 so that we get:
x/3 = -7 + 4 = -3
We then need to multiply both sides by 3 to get a singular x:
x = -3 * 3 = -9
