Answer:

r = -3

Step-by-step explanation:

We need to isolate r...

-8r+12=36

Subtract 12 from both sides

-8r=24

Divide both sides by -8

r= -3

We can check this answer...

-8r+12=36

-8(-3)+12=36

24+12=36

36=36 --> correct!

r = -3

If 5-3(2a+1)=-4+10, what is the value of a+2

givi [52]

$\\ \rm\Rrightarrow 5-3(2a+1)=-4+10$

$\\ \rm\Rrightarrow 5-6a-3=6$

$\\ \rm\Rrightarrow -6a+2=6$

$\\ \rm\Rrightarrow -6a=6-2$

$\\ \rm\Rrightarrow -6a=4$

$\\ \rm\Rrightarrow a=\dfrac{4}{-6}$

$\\ \rm\Rrightarrow a=\dfrac{2}{-3}$

Now

$\\ \rm\Rrightarrow a+2$

$\\ \rm\Rrightarrow \dfrac{2}{-3}+2$

$\\ \rm\Rrightarrow \dfrac{2-6}{-3}$

$\\ \rm\Rrightarrow \dfrac{-4}{-3}$

$\\ \rm\Rrightarrow \dfrac{4}{3}$

What is the product? One-eighth times three-elevenths 3 over 88 1 over 22 4 over 19 35 over 88

kipiarov [429]

Answer:

$\frac{3}{88}$

Step-by-step explanation:

Given

One-eighth times three-elevenths

Required

Solve

One-eighth means 1/8

Three-elevenths means 3/11

So, mathematically; the above expression is represented as thus:

$\frac{1}{8} * \frac{3}{11}$

To solve this, we simply multiply the numerator and the denominator together.

After multiplying these together, the next is to check if the resulting can be simplified

If yes,we simplify it and if otherwise, we live it like that.

So,

$\frac{1}{8} * \frac{3}{11}$

$=\frac{1 * 3}{8 * 11}$

$= \frac{3}{88}$

At this point, the fraction can't be simplified any further.

Hence,

$\frac{1}{8} * \frac{3}{11} = \frac{3}{88}$
