Answer:
6
Step-by-step explanation:
18x−(8x−7)=67
Step 1: Simplify both sides of the equation.
18x−(8x−7)=67
18x+−1(8x−7)=67(Distribute the Negative Sign)
18x+−1(8x)+(−1)(−7)=67
18x+−8x+7=67
(18x+−8x)+(7)=67(Combine Like Terms)
10x+7=67
10x+7=67
Step 2: Subtract 7 from both sides.
10x+7−7=67−7
10x=60
Step 3: Divide both sides by 10.
The new length of the string will be 16 1/4 feet. Then the correct option is B.
<h3>What is the length?</h3>
It is the measure of distance between the two points and is known as length. The length is measured in meters generally.
Ed needed to extend the string on his kite. The current string was seven and three-fourths feet that is (7 3/4).
The mixed fraction number is coverted into a decimal number.
7 3/4 = 7.75 feet
He cut a piece of string that measured 8.5 feet and added it to the existing string.
Then the new length of the string will be
L = 7.75 + 8.5
L = 16.25
L = 16 1/4 feet
The new length of the string will be 16 1/4 feet. Then the correct option is B.

A system of linear equations is a set of two linear equations with two variables.
Answer:
length = 6 yards
width = 3.5 yards
Step-by-step explanation:
the length of a rectangle is 1 yard less than twice the width
LEt 'w' be the width of the rectangle
and 'l' be the length of the rectangle
length l = 2 times the width -1
so l = 2w -1
Area of the rectangle = length * width
Area = l * w
we know length is 2w-1 and given area = 21
21 = (2w-1) * w
subtract 21 on both sides
now solve for 'w'
0 = 2w(w+3)-7(w+3)
0= (2w-7)(w+3)
2w-7 = 0 and w+3 =0
w = 7/2 w=-3
width cannot be negative so we ignore w=-3
width w= 3.5
length = 2w-1= 2(3.5) - 1= 7-1=6
length = 6 yards
Answer:
= h^-6
Step-by-step explanation:
When dividing powers you subtract them (indices rules)
--> -2 - 4 = -6
