LM is the midsegment of trapezoid ABCD. AB= x + 8, LM = 4x + 3, and DC = 187. What is the value of x?

Answers

Answer 1

Answer: Length of the midsegment of trapezoid:
LM = ( AB + DC ) / 2
4 x + 3 = ( x + 8 + 187 ) / 2 / * 2 ( we will multiply both sides of the equation by 2 )
8 x + 6 = x + 8 + 187
8 x + 6 = x + 195
8 x - x = 195 - 6
7 x = 189
x = 189 : 7
Answer:
x = 27

Answers

Answer:

The exponent would be negative because the original number is less than one.

Step-by-step explanation:

The given number is 0.0009763. We can write it as a single digit times a power of ten.

There are 3 zeroes after decimal and then 9 comes. As the original number is less than. It means we can write it as follows :

$0.0009763=9.76* 10^(-4)$

The exponent is negative here. The correct option is (c) "The exponent would be negative because the original number is less than one"

The answer is d.

3x-14 = x-2 solve for x

4y-7 = y+11 solve for y

3x-14=x+2
Add 14 to both sides.
3x=x+16
Subtract x from both sides.
2x=16
Divide by 2.
x=8

4y-7=y+11
Add 7 to both sides.
4y=y+18
Subtract y from both sides.
3y=18
Divide by 3.
y=6

The answer is d.
