Answer:
h = 430
Step-by-step explanation:
1290 = h/10 + h/5 Make h/5 into something that is something / 10
1290 = h/10 + 2h/(5*2) Clean up the brackets.
1290 = h/10 + 2h/10 Add the right.
1290 = 3h/10 Multiply both sides by 10
1290*10 = 10(3h/10)
12900 = 3h Divide both sides by 3
h = 430
(-20)7=140
All the other options have a wrong product. The first option forgot to include te negative sign. The second and last option were supposed to be positive not negative.
The third option is the only one that has a correct product so that means it is correct.
8 5/12 because you have to get the 3 fractions denomenators to be the same. so 3, 4 and 2 all go into 12 then you need go multiply the top by the same number as the bottom
Divide 8 by 8= 1
divide 40 by 8=5
1/5
The Mid - point of the line segment is at coordinates - M(- 7.5, 0.5)
We have two coordinate points - A(- 10, 2) and B(- 5, -1)
We have to find the midpoint of this line AB.
<h3>What is Mid - Point Theorem?</h3>
It states that a line with endpoint coordinates as -
and
has its mid - point at the coordinates -

According to question, we have -
First coordinate Point -
= (- 10, 2)
Second coordinate Point -
= (- 5, - 1)
Using the Mid - Point formula, we get -
=

Hence, the Mid - point of the line segment is at coordinates -
M(- 7.5, 0.5)
