Step-by-step explanation:
-2a + x
Putting values of a = - 2 and x = 7
-2(-2) + 7
4 + 7
= 11
A ratio is comparing one thing to another (numbers in this case). You can write ratios in many ways
here’s three different ways.
There are four girls and and 2 boys.
The ratio of girls to boys is:
4:2
4 to 2
4/2
*THE RATIO MUST ALWAYS BE IN ORDER!!! If boys come first in the problem WRITE THE BOYS NUMBER FIRST! If girls come first, WRITE THE GIRLS FIRST IN THE RATIO!!! (That’s a very common mistake) hope this helps!
Answer:
D
Step-by-step explanation:
The expression ![\sqrt[5]{x} *\sqrt[5]{x}* \sqrt[5]{x} *\sqrt[5]{x}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7Bx%7D%20%2A%5Csqrt%5B5%5D%7Bx%7D%2A%20%5Csqrt%5B5%5D%7Bx%7D%20%2A%5Csqrt%5B5%5D%7Bx%7D)
simplifies to ![\sqrt[5]{x*x*x*x} = \sqrt[5]{x^4}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7Bx%2Ax%2Ax%2Ax%7D%20%3D%20%5Csqrt%5B5%5D%7Bx%5E4%7D)
A radical can be written as a fractional exponent. The index of a radical is the denominator of its fractional exponent.
Answer:
-2x+3(-5x+1)=-2x+(-15x+3)
=-2x-15x+3
=-17x+3
-5/3a+1/8-1/6a-1/2=-5/3a-1/6a+1/8-1/2
=-40/24a-4/24a+3/24-12/24
=-44/24a-9/24
=-11/6a-3/8
3(1/5x-1/7)=3/5x-3/7
Hence, ans: C
-1.5w+7.5=1.5(-w+5)
=-1.5(w-5)
Hence, ans: A
