Solve for -(6h+7)+8=-19

Mathematics
1 answer:

Step One:
Distribute.
-(6h+7)+8=-19
Distribute the negative into the parentheses.
-6h-7+8=-19
Combine any like-terms.
-6h+1=-19
Solve for h. Subtract 1 from both sides.
-6h=-20
Divide by 6 on both sides.
h = 20/6
Simplify the fraction.
h = 10/3

The answer is D. To help find the answer, you can remember an easy rule. The rule is if you're subtracting a positive number from a negative number, it will always be negative thus eliminating any answers that are positive.

Help on this one as well ii manged to get an answer but If you understand it or im wrong an you please explain ! thank you !!
AnnZ [28]
Almost got it!

x + 3 = 3(y + 2)/2 [Multiplied both sides by 3]
so x + 3 = (3y + 6)/2
2(x + 3) = 3y + 6 [Multiplied both sides by 2]
2x + 6 = 3y + 6
2x = 3y [Subtracted 6 from both sides]
x = 3y/2 [Divided both sides by 2]
x/3 = y/2 [Divided both sides by 3]

So you wrote y/3 instead of y/2 
Hope this helped!

Look at the figure. Name the postulate or theorem you can use to prove the train goes congruent?
Nikolay [14]

Let us recall parallelogram properties, which states that opposite angles of parallelogram are congruent.

We can see from graph that side US is parallel to TR and measure of angle U equals to measure of angle R, therefore, quadrilateral drawn in our given graph is a parallelogram.

Since we know that opposite sides of parallelogram are congruent. In our parallelogram UT=SR and US=TR.

In our triangle STU and triangle TSR side TS=TS by reflexive property of congruence.

Therefore, our triangles are congruent by SSS congruence.
