Answer:
x=12
Step-by-step explanation:
(2x-4)/5=4
We move all terms to the left:
(2x-4)/5-(4)=0
We multiply all the terms by the denominator
(2x-4)-4*5=0
We add all the numbers together, and all the variables
(2x-4)-20=0
We get rid of parentheses
2x-4-20=0
We add all the numbers together, and all the variables
2x-24=0
We move all terms containing x to the left, all other terms to the right
2x=24
x=24/2
x=12
Answer:
x = 12
Step-by-step explanation:
Given
[tex]\frac{2x-4}{5}[/tex] = 4 ( multiply both sides by 5 to clear the fraction )
2x - 4 = 20 ( add 4 to both sides )
2x = 24 ( divide both sides by 2 )
x = 12

Part B: Explain how you found the measure of angle x by identifying the angle relationships that you used along the transversal. (5 points)
AB and CD are parallel lines, and PQ and PR are transversals which intersect AB at P and CD at Q and R. Angle APQ is labeled as 65 degrees, angle QPR is equal to x, angle PRD is equal to 120 degrees.
Answers
Answer:
45 degrees
Step-by-step explanation:
pretty sure
Answer:
x = 55
Step-by-step explanation:
to find angle BPR you would do:
180 - 120 = 60
so BPR is 60°
now to find x you do this:
65 + 60 + x = 180
125 + x = 180
x = 55

pool is 16 feet, what is its width?
Answers
Answer:
8.75 feet
Step-by-step explanation:
Use the area formula, A = lw, where l is the length and w is the width
Plug in the area and length, and solve for w:
A = lw
140 = 16w
8.75 = w
So, the width is 8.75 feet
Answer:
8.75 ft
Step-by-step explanation:
Use the area formula, A = lw, where l is the length and w is the width
Plug in the area and length, and solve for w:
A = lw
140 = 16w
8.75 = w

Find x no need for explanation I just need answer thanks
Answers
Answer:
x = 12 m
Step-by-step explanation:
Length = x m
Width = 3⅔ = 11/3
Area = 44 m²
Area of rectangle = length × width
Plug in the values into the equation
[tex] 44 = x \times \frac{11}{3} [/tex]
[tex] 44 = \frac{11x}{3} [/tex]
Multiply both sides by 3
[tex] 44 \times 3 = \frac{11x}{3} \times 3 [/tex]
[tex] 132 = 11x [/tex]
Divide both sides by 11
[tex] 12 = x [/tex]
x = 12

How can you use x- and y- intercepts to graph an equation
Answers
Answer:
Since two points determine any line, we can graph lines using the x- and y-intercepts. To find the x-intercept, set y = 0 and solve for x. To find the y-intercept, set x = 0 and solve for y. This method of finding x- and y-intercepts will be used throughout our study of algebra because it works for any equation.

The total cost of the haircut including the tip will be $28.32.
How to calculate unit price of something?Unit means 'single entity', the fundamental constructing block. Usually, it is 1 in mathematics and science.
Thus, unit price of something is price of 1 thing.
Thus, suppose we're taking about price of mangoes, then unit price will denote the price of 1 mango.
It is given that Vera went to the local salon to get a haircut. The cost was $24. Vera tipped the hair stylist 18%.
SO,
18% = 18/100 = 0.18
18% of 24 = 0.18*24
= 4.32
The tip is $4.32
Adding this tip amount onto the original bill leads to;
4.32+24 = 28.32
Hence, the total cost of the haircut including the tip will be $28.32.

The answers to each part is given below.
What is percentage?In mathematics →
a percentage is a number or ratio expressed as a fraction of 100.it is often denoted using the percent sign "%".Given is that you buy a watch for $60.
{a} -Total cost of watch -
{C} = ${60 + (6% of 60)}
{C} = ${60 + (6/100 x 60)}
{C} = $(60 + 3.6}
{C} = $63.6
{b} -New sale price -
{D} = 60 - (15% of 60)
{D} = 60 - (15/100 x 60)
{D} = 60 - 9
{D} = $51
{c} -Total cost of watch including tax -
{CT} = 51 + (6% of 51)
{CT} = 51 + 3.06
{CT} = 54.06

Solve for Y.
Answers
Answer:
6=2(y+2)
distributive property
6=2(y)+2(2)
6=2y+4
-4 -4
2=2y
-- --
2 2
divide two in both sides to get y by itself
y=1
Answer:
y = 1
Step-by-step explanation:
6 = 2 (y + 2)
Distribuite:
2 * y = 2y
2 * 2 = 4
2y + 4 = 6
Use additive inverses. The additive inverse of addition is subtraction.
Subtract 4 from both sides:
2y + 4 - 4 = 6 - 4
6 - 4 = 2
2y ÷ 2 = 2 ÷ 2
2y ÷ 2 = y
2 ÷ 2 = 1
To check our answer we multiply how much y is (which is 1) by 2.
2(1) + 4 = 6
2 * 1 = 2
2 + 4 = 6.
