None of given </h3><h3>
x = -1²/₇ </h3>
Step-by-step explanation:
-(-10x - 8) = -(4x + 10)
10x + 8 = -4x - 10
-8 -8
10x = -4x - 18
+4x +4x
14x = -18
÷14 ÷14
x = -¹⁸/₁₄ = -⁹/₇ = -1²/₇
I think you meant -(10x-8)=-(4x+10)
Then:
-(10x - 8) = -(4x + 10)
-10x + 8 = -4x - 10
-8 -8
-10x = -4x - 18
+4x +4x
-6x = -18
÷(-6) ÷(-6)
<h3>
x = 3 D)</h3>
Answer:
Step-by-step explanation:
1) x=14 y=40
2)a=10 b=37
3)u=62 v=59
4)s=9 t=14
5)u=66 v=38

Answer:we multiply by the reciprocal of a fraction when completing a division problem because it is a rule in mathematics that when you divide two fraction, you change the division sign to multiplication and flip the fraction at the right of the multiplication sign.
Step-by-step explanation:
For example if you have 4÷ 1/2. It basically means how many 1/2 can one get in 4. And the answers is 8.
Therefore multiplying by the reciprocal of a fraction when completing a division problem is a short cut method that has been tested and proven to be correct.
Answer:
C.) each treatment is thought of as a value of the explanatory variable
Step-by-step explanation:
The main purpose for using randomization in an experiment is to control the lurking variable and establish a cause and effect relationship.
If we do not control lurking, or confounding, variables, we cannot accurately establish a cause and effect relationship; this means we cannot ensure that each treatment is a value of the explanatory variable.
5,000,000 is the answer.
5,000÷0.001=5,000,000
