Answer:
d.) 2
Step-by-step explanation:
If you were going to solve the second part of the equation you would distribute and since we want the number we chose to equal 8, so the sides will be equivelent and their will be infinite solutions, we have to account for the *4 so if we do 8 ÷ 4 we will have the number we should use for infinite solutions
8÷4=2
You can also check it by putting 2 in the equation
4x + 8 = 4(x+2) now distribute the 4
4x+8=4x+8
Answer:
Step-by-step explanation:
Let the two angles be 3x and 7x.
Supplementary angles add up to 180 degrees.
Therefore:
3x + 7x = 180
10x = 180
x = 18
3x = 3 * 18 = 54
7x = 7 * 18 = 126
Answer:
The two angles are 54 degrees and 126 degrees.
Answer:
100 or 91
Step-by-step explanation:
The number 92 has 9 tens and 2 ones. A number with fewer ones will have 0 or 1 of them. Any number ending in 0 or 1 will be an answer to this question. Two possibilities are shown above.
Answer:
D, F.
Step-by-step explanation:
D and F contain x^2.
Answer:
(-2)*3= -6
Step-by-step explanation:
adding -2 three times is the same as multiplying by three
