9.) 1/2(4x-6)=11
Multiply 4 and -6 by 1/2
2x-3=11
Add 3 to both sides
2x=14
Divide 14 by 2
Final Answer: x=7

10.) 2/3(6x-9)=-34
Multiply 6 and -9 by 2/3
4x-6=-34
Add 6 to both sides
4x=-34
Divide -34 by 4
Final Answer: x=-8.5

To some Marines one cruising at 25 kn in the other 20 kn left the naval base at the same moment. Three hours later they were 100

I believe you would have to multiply both 25 and 20 and what ever number you get dived by 100 if the numbers to high multiply aging or subtract the number (if it's wrong I'm really not good at my math I'm sorry)

$\bf \textit{how much is }\frac{1}{100}\quad of \quad 10^{20}?\implies \stackrel{\textit{one hundredth}}{\cfrac{1}{100}}\cdot 10^{20}\implies \cfrac{1}{10^2}\cdot 10^{20}
\\\\\\
10^{-2}\cdot 10^{20}\implies 10^{-2+20}\implies 10^{18}

Answer:

AC ≈ 7.3

Step-by-step explanation:

Corresponding sides of similar triangles are proportional.

AC/BC = DF/EF

AC/18 = 15/37 . . . . fill in the given values

AC = 18(15/37) . . . multiply by 18

AC ≈ 7.3

Can anyone please help me?

Answer:

Step-by-step explanation:

Parentheses mean multiplication in this case. So it would be 2 x -3 OR -3 + -3. When multiplying a negative and a positive the answer will ALWAYS be negative. So you would move to the left on a number line.
