How many gallons of red paint will she use to paint her whole wall?
A) 21/50
B)7/15
C) 1 1/6
D) 1 3/10
Answers
Answer:
1 1/6 gallons will paint the whole wall
Step-by-step explanation:
7/ 10 gallon paints 3/5 of wall
x gallon will paint 1/1 of wall
7/10 * 1 = x * 3/5
7/10 = 3x/5
3x * 10 = 5 * 7
30x = 35
x = 35/30

y is directly proportional to x. when x = 8, y = 20. determine the value of y when x = 3
Answers
Step-by-step explanation:
y is directly proportional to x
y = kx
k represents the constant of proportionality.
when y = 20 and x = 8:
20 = 8k
Dividing both sides by 8 gives:
k = 2.5
Hence when x = 3.
y = 2.5(3)
y = 7.5 .
The value of y when x=3 is 7.5
What is proportion?In general, the term "proportion" refers to a part, share, or amount that is compared to a total.
According to the concept of proportion, two ratios are in proportion when they are equal.
A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.
Given:
y is directly proportional to x.
and, when x = 8, y = 20.
So, using proportion
8/20 = 3/y
8y = 60
y= 60/8
y= 7.5
Hence, the value of y is 7.5

Mariah earns $32.75 per week working as a pet sitter. She worked as a pet sitter for 2 weeks. She previously saved $70.99 in allowance money. She spent $12.25 of her total earning to buy video games. Mariah put 1 over 4 of the remaining money in her savings account. Mariah used the following steps to find the total money she put in her savings account:
Step 1: [($32.75 ⋅ 2) + $70.99 − $12.25] ⋅ 1 over 4
Step 2: [$65.5 + $70.99 − $12.25] ⋅ 1 over 4
Step 3: $136.49 − $3.0625 = $133.4275
In which step did Mariah first make an error? Explain, using words, how Mariah can correct her error.
Answers
Answer:
1) Step 3: S = $136.49 - $3.0625 × 1/4
2) By completing the operations within the parenthesis in Step 2, before multiplying the result by 1/4
Step-by-step explanation:
1) From the given information, we have;
The amount amount Maria earns as a pet sitter = $32.75
The number of weeks Maria worked as a pet sitter = 2 weeks
The amount Mariah previously saved = $70.99
The amount Maria spent = $12.25
The amount Mariah put in her savings account = 1/4 of the remaining (balance) money
Therefore, we have;
The amount placed in Mariah's savings account, S, is given as follows;
Step 1: S = [($32.75 × 2) + $70.99 - $12.25] × 1/4
Step 2: S = [($65.5 × 2) + $70.99 - $12.25] × 1/4
Step 3: S = [($136.49) - $12.25] × 1/4
Step 4: S = $124.24 × 1/4
Step 5: S = $31.06
The amount Mariah puts in her saving's account = $31.06 and the step Mariah first makes an error is Step 3 where what she put down was as follows;
Step 3: S = $136.49 - $3.0625 × 1/4
2) She can correct the error by completing the calculation of the operation within the parenthesis in Step 2, before multiplying by the factor 1/4.
find the value of x that makes m||n
Answers
Answer:
x = 6
Step-by-step explanation:
In order for m to be parallel to n 16x - 6 would have to equal 90. We can demonstrate that using an equation.
16x - 6 = 90
Let's solve for x:
First add 6 to both sides to isolate the 16x:
16x - 6 + 6 = 90 + 6
16x = 96
Now divide both sides by 16 to isolate the x:
16x/16 = 96/16
x = 6
The value of x has to be 6 in order for m to be parallel to n.
Activity Warren's tape measure is marked in increments of 16 inch, not in decimal numbers. To measure the tiles, he needs to know the side lengths to to incħ. In this activity, you will convert decimal values to fractional values and then calculate the area of the tiles. the nearest Question 1 Part A The length of tile A is about 2.23607inches, which mark on the tape measure is closest to 2.23607inches? Remember, the tape measure is marked in sixteenths of an inch.
Answers
Answer:
the fourth mark after 2 inches
Step-by-step explanation:
each tile measures 2.23607 inches long
That means that the mark will be 2 inches and somewhere in between the third and fourth mark. The third mark is equivalent to 0.1875 inches and the fourth mark is equivalent to 0.25 inches. The mark closest to the actual length of the tile would be the fourth mark after 2 inches.
each mark represents 1 / 16 = 0.0625 inches, if we divide 0.23607 by 0.0625 = 3.69072 marks which we can round to 4 marks

The equation of the line representing the graphed function is y = ( 3/ 2 ) x - 3. Option E is correct.
What is an equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
The equation is formed by finding the slope using the coordinates ( 0,-3 ),( 2, 0 ) and ( 4, 3 ).
The slope is calculated as,
[tex]m = \dfrac{x_2-x_1}{y_2-y_1}[/tex]
x₁ = 0, y₁ = -3 and x₂ = 2, y₂ = 0.
The equation is given as,

Answer:
The answer is x = 15.
Step-by-step explanation:
To solve this problem, we must first notice that the two angles given are supplementary (their sum adds to 180 degrees).
This lets us create the following equation:
(6x-5) + (6x+5) = 180
We can get rid of the parentheses and simplify the left side of the equation.
6x + 6x - 5 + 5 = 180
12x = 180
To solve for x, we must divide both sides of the equation by 12.
x = 180/12 = 15
Therefore, the correct answer is x = 15.

Solve the system by substitution 5x+y=-10. 4x-7y=-8
Answers
Answer:
x = -2 and y = 0
Step-by-step explanation:
5x + y = -10
4x - 7y = -8
Rearrange the first equation to equal y.
5x + y = -10
y = -10 - 5x
Replace y in the second equation with the first equation.
4x - 7y = -8
4x - 7(-10 - 5x) = -8
4x - (-70 -35x) = -8
4x + 70 + 35x = -8
Rearrange the equation to find x.
4x + 35x = -8 - 70
39x = -78
x = -2
Now that you know x, use the rearranged first equation to find y.
y = -10 - 5x
y = -10 - 5(-2)
y = -10 + 10
y = 0
