What is -13=-h-7 step by step.?

2 answers:

7 0

Since it’s -7 you’re going to add seven to both sides so -7 and +7 cancel each other out then -13+ positive seven so -13+7 should be -6 then since there’s a one behind the eight today and it should basically just be six

We need to make h alone.
Add 7 to both sides to remove -7 from the right, and multiply both sides by -1 to make h positive. Doesn't matter which you do first.
Result:
6=h
h=6

Work out b(4½-3⅔)+1⅔

Zolol [24]

Answer:

2 $\frac{1}{2}$

Step-by-step explanation:

Change the mixed numbers to improper fractions

( $\frac{9}{2}$ - $\frac{11}{3}$ ) + $\frac{5}{3}$ ← the LCM of 2 and 3 is 6

= $\frac{9(3)}{2(3)}$ - $\frac{11(2)}{3(2)}$ + $\frac{5(2)}{3(2)}$

= $\frac{27}{6}$ - $\frac{22}{6}$ + $\frac{10}{6}$

= $\frac{5}{6}$ + $\frac{10}{6}$

= $\frac{15}{6}$

= $\frac{5}{2}$

= 2 $\frac{1}{2}$

What is the answer to the equation 5+2(x-1)=12

S_A_V [24]

$5+2(x-1)=12 \\ \\ 2 ( x - 1) = 12 - 5 \ / \ subtract \ 5 \ from \ each \ side \\ \\ 2(x - 1) = 7 \ / \ simplify \\ \\ x - 1 = \frac{7}{2} \ / \ divide \ each \ side \ by \ 2 \\ \\ x = \frac{7}{2} + 1 \ / \ add \ 1 \ to \ each \ side \\ \\ x = \frac{9}{2} \ / \ simplify \\ \\$

So, the answer to this problem is x = 9/2 or x = 4.5.

What is the length of BC?<br> pls help

zheka24 [161]

It’s an isosceles triangle, so those two sides are equal:

3x-15=x+33
2x=48
x=24, so BC should be 24.
