Answer:
Step-by-step explanation:
To distribute means to multiply everything outside the parenthesis with everything inside the parenthesis, so in this case 7x8 then 7(x) then 7x2 so that is equal to 56 + 7x + 14, so combine the 56+14 so we get 7x + 70. I hope '7' is part of the problem and not the question number
Answer:
80 gummy bears are in 4 servings.
Step-by-step explanation:
2 servings=40 gummy bears
3 servings=60 gummy bears
<u>40</u>+20=<u>60</u>
Add 20 gummy bears for every serving.
5 servings=100 gummy bears
100-20=<u>80 gummy bears are in 4 servings</u>
OR you can also do:
40÷2=20 gummy bears are in each serving
So, 4x20=<u>80 gummy bears are in 4 servings</u>

Answer:
B) x = 3
Step-by-step explanation:
The given triangle has three angles:
∠R, ∠S and ∠T
The exterior angle theorem says that
∠S+∠T = ∠R
Putting the values of angles
(57+x) + 25x = 45x
57 + x + 25x = 45x
57+26x = 45x
57 = 45x - 26x
57 = 19x
x = 57/19
x = 3
Hence, the correct answer is:
B) x = 3 ..
