Answer:
20x^2 - 107x - 10.
Step-by-step explanation:
8x - 108x - 10 - (9x^2 + 7x -29x^2)
simplifying:
-100x - 10 - (7x - 20x^2)
20x^2-100x - 7x - 10
20x^2 - 107x - 10

Answer:
3
Step-by-step explanation:
$1.75 (ice cream) + $0.35 (topping) * x (some toppings) = $2.80, so I can rewrite it like that: 1.75+0.35x=2.80
1) Move the constant to the right side and change its sign: 0.35x=2.8-1.75
2) Substract the numbers: 0.35x=1.05
3) Divide the both sides of the equation by 0.35
4) x=3
Answer: 32
Angle EBD= 31
Angle CBE=31
31+31=62
94-62=32
Answer:

Step-by-step explanation:
In order to solve this problem, first you need to simplify the expression to use a distributive property.
<u>Distributive property:</u>

5+2b-2
Switch sides.
2b+5-2
Combine like terms.
You have to subtract by the numbers from left to right.
Solve.
5-2=3
<u>2b+3</u>
- <u>So, the correct answer is 2b+3.</u>
