2x-54 and x + 22 are vertical angles and equal each other. Set the two equations equal to each other and solve for x.

2x -54 = x + 22

Add 54 to both sides:

2x = x + 76

Subtract 1x from each side:

X = 76

The answer is x = 76

Simplify 18x^2y/27xy^3z
Kipish [7]
First apply the exponent rule of...
a^{b}  * a^c = a^{b + c} \ \textgreater \  x^2x = x^{2 + 1} = x^3 \ \textgreater \  18x^3y^3 \frac{y}{27}z
Now we want to multiply the fractions.
a *  \frac{b}{c} =  \frac{a * b}{c}  \ \textgreater \  y * \frac{18x^3y^3z}{27} \ \textgreater \  y * 18x^3y^3z
Now apply the exponent rule of..
a^b * a^c = a^{b * c} \ \textgreater \  y^3y = y^{1 + 3} = y^4 \ \textgreater \  18x^3y^4z \ \textgreater \   \frac{18x^3y^4z}{27}
Cancel the common factor which is 9.

A shipment to a warehouse consists of 500 PS4. The manager chooses a random sample of 50 PS4 and finds that 3 are defective. How
crimeas [40]

Answer:

30 PS4's

Step-by-step explanation:

The manager chose 50/500 PS4's to sample

3/50 were defective

To find how many were defective in all 500, we multiply the fraction by a number that makes the 50 (the sample), into a 500(the total).

That number is 10

Whatever multiplication you do to the bottom of a fraction, you do to the top

3*10 / 50*10

30 / 500 are likely to be defective

Gracie, Mary, and Nancy each have a small collection of seashells. Gracie has 5 more than 1 1/4 times the number of shells Mary
Zolol [24]
G = 1.25m + 5
n = 1.50n + 1
g = n

1.25m + 5 = 1.50m + 1 <== ur equation
5 - 1 = 1.50m - 1.25m
4 = 0.25m
4 / 0.25 = m
16 = m <== mary has 16 <==

g = 1.25m + 5....g = 1.25(16) + 5....g = 25 <==Gracie has 25 <==
n = 1.50m + 1...n = 1.50(16) + 1.....n = 25 <==Nancy has 25 <==

The measures of two complementary angles have a ratio of 3 : 2. What is the measure of the larger angle?
Nonamiya [84]

Answer:

larger angle:  54°

Step-by-step explanation:

90 / (3 + 2) = 18

larger angle: 13 x 3 = 54°

check: smaller angle: 18 x 2 = 36°

           54 + 36 = 90°

What is 3(x-5)-14=2(x-7)+2
Evgen [1.6K]

Answer: x = 7

Step-by-step explanation:

To solve the equation,

First step, open the bracket

3(x-5)-14=2(x-7)+2

3x -15 -14 = 2x -14 +2

Then, add the like terms

3x - 29 = 2x -16

Transpose the values at the right hand side to the left hand side

3x - 2x = -16 + 29

x = 7
