Answer:
100 red bricks
Step-by-step explanation:
Let's say red bricks is equal to 5x
Gray bricks is equal to 2x
We have an equation
2x + 5x = 140
= 7x = 140
Divide through by 7 to get the value of x
X = 140/7
X = 20
Red bricks = 5(x)
= 5(20)
= 100
Gray bricks = 2(x)
= 2(20)
= 40
Therefore in conclusion the number of red bricks is 100.
a(-6)=-42
solve for a
Answer:
7
Step-by-step explanation:
Answer:
A = 7
Step-by-step explanation:
You would take -42/-6 because that will tell you what x -6=-42
-42/-6 = 7
Also. you have to remember that a negative divided or multiplied by a negative = a positive

enough drinks for 28 people, how many cups of orange juice will she
need? *
Answer:
11 1 /2 ( 11 and a half)
Step-by-step explanation:
If you noticed 7 and 2 are five numbers away.
To solve this I just added one to both of them until the sum was equal to 28.
If I had added one to 16 and 11, it would have given me 29, so I added a half.
That gave me 28.

The diagonals of a rectangle have length 12 and intersect in a 40 degree angle. Find the length and width rounded to the nearest tenth.
Answer:
Length is 7.7 and width is 9.2
Step-by-step explanation:
The length and width of the rectangle will be the y and x coordinate of the diagonal line at angle of 40 degrees
Length L = dsin theta
Width W = d coos theta
d is the length of the diagonal
Given
d = 12
theta = 40°
Substitute
Length = 12sin40°
Length = 12(0.6428)
Length = 7.7135
Length ≈ 7.7
Width = 12cos 40
Width = 12(0.7660)
Width = 9.192
Width = 9.2
Hence the length is 7.7 and width is 9.2

Jana earns $25 per week for mowing the lawn and deposits the money into her savings account. The amount of money in Jana's account can be
represented by the equation y = 25x + 125, where x is the number of weeks she has been mowing the lawn. What does the y-intercept of the graph
represent in this situation?
Hi there! x would be 6 weeks..
Explanation:
So here says that Jana earns $25 per week for mowing the lawn. But in “x” weeks, she earns $125...this means that you would have to divide 125 with 25 or 25 multiply by x to find the answer of x.
How much does 25 go to 100? Well it would be 5. So for $100 it would be 5 weeks. We also know that 25 is 1 week. So add 5 with 1. 5 plus 1 would be 6.
Therefore, for $125, Jana would have to work for 6 whole weeks.

Find X Give your answer in simplest form
Given:
A figure of a right angle triangle.
To find:
The value of x.
Solution:
In a right angle triangle,
[tex]\tan \theta = \dfrac{Opposite}{Adjacent}[/tex]
In the given triangle,
[tex]\tan (30^\circ) = \dfrac{x}{7}[/tex]
[tex]\dfrac{1}{\sqrt{3}}=\dfrac{x}{7}[/tex]
On multiplying both sides by 7, we get
[tex]\dfrac{7}{\sqrt{3}}=x[/tex]
Therefore, the value of x is [tex]x=\dfrac{7}{\sqrt{3}}[/tex].

If the price of a sweater was $37.38 after a 35% discount, what was the original price? Round your answer to the nearest cent.
Answer:
$57.51
Step-by-step explanation:
If the price of a sweater was $37.38 after a 35% discount, what was the original price? Round your answer to the nearest cent.
The formula for the original price =
= Sales price/1 - Percentage discount
Percentage discount = 35% = 0.35
Original price = $37.38/1 - 0.35
= $37.38/0.65
= $57.507692308
Approximately = $57.51
Therefore, the original price H= $57.51
Rochelle is competing in a marathon. She knows that once she runs 14.7 km she will have completed 35% of the marathon
Given :
Rochelle is competing in a marathon.
She knows that once she runs 14.7 km she will have completed 35% of the marathon.
To Find :
Total length of the marathon.
Solution :
Let, total distance of the marathon is x km.
So, 35% of x is 14.7 .
In mathematics :
[tex]14.7 = x\times \dfrac{35}{100}\\\\x = \dfrac{14.7\times 100}{35}\\\\x = 42\ km[/tex]
Therefore, total length of the marathon is 42 km.

Answer:
416Step-by-step explanation:
For this to have infinitely many solutions, the left side and right side must simplify to the same expression. The left side is already simplified, so we need to find the right numbers for the right side.
Coefficient of x:
7x = __x + 3x
4x = __x . . . . . . subtract 3x; next divide by x
4 = __ . . . . . the required x-coefficient is 4
Constant term:
-8 = 8 -__
-16 = -__ . . . . . subtract 8
16 = __ . . . . . . multiply by -1
__
The numbers that go in the boxes are 4 and 16.
