Which number should each side of the equation 2/3x=10 be multiplied by to produce the equivalent equation of x = 15?
−2/3
1/3
3/2
3
Answer:
3/2
Step-by-step explanation:
If you want to get the coefficient of x to be 1, you multiply by the reciprocal of the coefficient. The reciprocal is 3/2, so you multiple by 3/2
A coin is tossed two times, then a month of the year is randomly selected. What is the probability of getting tails each time, and a month that starts with the letter J? I got 1/8 is that correct if not what’s the answer
Answer:
1/16
Step-by-step explanation:
1/2 getting tails
1/4 getting tails twice
3/12 getting a J month =1/4
1/4 x 1/4 =1/16
Answer:
1/16
Step-by-step explanation:
Given a fair coin, the probability of getting tails on any one toss =
P(tails) = 1/2
if a coin is tossed twice and we get tails both times,
P( 2 tails on 2 consecutive tosses) = (1/2)(1/2) = 1/4
Total number of months = 12 months
Months that start with J = January, June, July = 3 months
P(selecting months that start with J) = 3/12 = 1/4
Hence the probability of tossing 2 consecutive tails then selecting a month that starts with J
= (1/4) x (1/4)
= 1/16

Cesar had a part-time job last year. He worked every week for the year and made $23 an hour. He worked 28 hours each week. Cesar saved
what was left of his earnings after paying all of his monthly expenses. At the end of the year, he had saved $3,360. What were Cesar's average
monthly expenses, rounded to the nearest dollar?
A
$1,288
B. $1,680
C. $2,403
D. $2,511
E. $2,791
Answer:
D. $2,511
Step-by-step explanation:
First off, we need to write down the facts we know.
There are about 52.177 weeks in a year
Cesar works 28 hours each week
Cesar makes $23 an hour
There are 12 months in a year
Cesar has $3,360 after his monthly expenses
To figure out how many hours are in a "work year," multiply the number of work hours in a week by the number of weeks in a year. In other words, multiply Cesar's 28 hour work week by about 52.177 weeks. That makes 1,456 hours in his work year. That means he makes $33,492 a year. If you multiply $2,511 by the months in a year (12), you get $30132. Finally, subtract his annual salary by $30132 to get $3,360, which is what was left of Cesar's earnings after paying all of his monthly expenses. This means that your answer is: D. $2,511.
Answer:
D. $2,511
Step-by-step explanation:
$23 x 28 x 52 = $33,488
$33,488 ÷ 12 = $2,790.66 = $2,791
12($2,791) - $3,360 = 30,132
$30,132 ÷ 12 = [$2,511]

>>>>correct ans is 7.5 by 30
Answer:
7.5 feet by 30 feet
Step-by-step explanation:
i believe you would take 12 and divide it by 2 and then multiply it by 5=30. And then do the same for 3. 3 divided by 2 =1.5 and 1.5 multiplied by 5 =7.5
The answer would be 7.5 feet by 30 feet

Answer these questions about the steps of simplifying this rational expression: 4x-8/x^2+3x-10 Part A What is the greatest common factor (GCF) of the terms in the numerator and in the denominator? Rewrite the expression by factoring out the GCF.
Answer:
GCF: (x - 2)
4 / (x + 5)
Step-by-step explanation:
The expression given is:
(4x - 8) / (x² + 3x - 10)
To find the greatest common factor, we have to factorise the numerator and denominator individually.
NUMERATOR:
4x - 8 = 4(x - 2)
DENOMINATOR:
x² + 3x - 10 = x² + 5x - 2x - 10
x² + 3x - 10 = x(x + 5) - 2(x + 5)
x² + 3x - 10 = (x - 2) ( x + 5)
So, the expression becomes:
4(x - 2) / [(x - 2) ( x + 5)]
We observe that the common factor in both numerator ad denominator is (x - 2).
This is the greatest common factor (GCF).
Factoring out (x - 2), the expression can be rewritten as:
4 / (x + 5)
Answer:
The terms in the denominator have a GCF of 1, so nothing gets pulled out in the denominator. The GCF of the terms in the numerator is 4.

A rectangle has a perimeter of (20x+12y). If one side of the rectangle is (3x-4y), write the expression for the other side
Answer:
(7x + 10y)
Step-by-step explanation:
To find this add (3x - 4y) to itself to calculate to lengths of the shorter sides.
(3x - 4y) + (3x - 4y) = 6x - 8y
Subtract this from (20x + 12y)
(20x + 12y) - (6x - 8y) = 14x + 20y Divide this by two to get the length of one side
14x + 20y / 2 = 7x + 10y
If this answer is correct, please make me Brainliest!
The expression for the other side of the rectangle, when one side is (3x-4y) and the perimeter is (20x+12y), is (7x + 10y).
To determine the expression for the other side of the rectangle with a perimeter of (20x+12y) and one side being (3x-4y), we must remember that the perimeter of a rectangle is calculated by adding together twice the length and twice the width (P = 2l + 2w). Since we have one length, we can solve for the width by dividing the perimeter by 2 and subtracting the length.
First, let's find half of the perimeter by dividing the given perimeter by 2:
(20x + 12y) / 2 = 10x + 6y
This represents the sum of one length and one width. We then subtract the given side (one length) from this to find the other side (one width):
(10x + 6y) - (3x - 4y) = 10x + 6y - 3x + 4y = 7x + 10y.

Step-by-step explanation:
[tex]\sqrt{100}=10[/tex] because [tex]10^{2}=100[/tex]. 10 is the square root of 100, which means that 10 multiplied by itself (10×10=[tex]10^2[/tex]) is equal to 100. So, when you are trying to find the square root of a number, the square root is itself multiplied by itself.

An artist is making a rectangular canvas for a custom painting. the canvas has a width of 9 1/2 feet and a length of 13 1/4 feet . what is the area of canvas in square feet?
The area of a rectangle is given by the formula
[tex]A=L\cdot w[/tex] (1)
where
A is the area
L is the length
w is the width
In this problem, we have a rectangular canvas, so we want to find its area.
We know that:
[tex]w=9\frac{1}{2}ft[/tex] is the width, converting into an improper fraction,
[tex]w=\frac{9\cdot 2+1}{2}=\frac{19}{2}[/tex] ft
[tex]L=13\frac{1}{4}ft[/tex] is the length, converting into improper fraction,
[tex]L=\frac{13\cdot 4+1}{4}=\frac{53}{4}[/tex] ft
Substituting into eq (1), we can find the area of the canvas:
[tex]A=\frac{19}{2}\cdot \frac{53}{4}=\frac{1007}{8}=125.9 ft^2[/tex]

Answer:
distributive property, subtraction, division
Step-by-step explanation:
i don't know the exact name of the last two but that's what i'm assuming they're called lol
The properties used to solve the equation 4(x + 3) = 20 are the distributive property, subtraction property of equality, and division property of equality. First, the distributive property is used to expand the left-hand side, then subtraction is used to isolate 4x. Finally, division is used to find x = 2.
Explanation:The question provides an algebraic equation and uses properties to solve for the variable 'x'. The steps taken demonstrate the following properties:
Distributive property: The equation starts as 4(x + 3) = 20. Through the distributive property (a*(b + c) = a*b + a*c), this is expanded to 4x + 12 = 20.Subtraction property of equality: Next, 12 is subtracted on both the sides giving 4x = 8. This property states that we can subtract the same value from both sides of the equation and it will still hold true.Division property of equality: Finally, the equation is divided by 4 on both sides, which results in x = 2. This property tells us that if we divide both sides of the equation by the same non-zero number, the equation will still be equal.Learn more about Algebraic Properties here:https://brainly.com/question/32858114

If the volume of the pyramid shown is 360 inches cubed, what is its height?
A rectangular pyramid with base of 12 inches by 10 inches and a height of h.
1 in.
3 in.
6 in.
9 in.
Answer:
9 inches
Step-by-step explanation:
The formula for the volume of a rectangular pyramid is
Here we have volume (V), base (L), and width (W)
V = 360 in³, L = 12 in, W = 10 in
We need to manipulate the volume equation to solve for the height (H)
First we need to multiply both sides by 3 to get rid of the fraction: 3V = L×W×H
Then we need to divide both sides by (L×W) to get:
Now we can plug in the given values:
