Answer:
-3
Step-by-step explanation:
-2(5x+1)=58+10x
=>-10x + -2 = 58 + 10x
=> -10x -10x = 58 + 2
=> -20x = 60
=> x = 60/-20
=> x = -3

Find the missing length of the triangle.
4 yd
12; yd
2
yd
Answer:
Missing length = [tex]11\frac{2}{3}[/tex]
Step-by-step explanation:
By Pythagoras theorem,
Square of the longest length = Sum of square of smaller lengths of the triangle
[tex](\frac{37}{3})^2=a^2+4^2[/tex]
a² = 152.11 - 16
a² = 136.11
a = √136.11
a = 11.67 Or [tex]11\frac{2}{3}[/tex]
Therefore, missing length of the given triangle will measure [tex]11\frac{2}{3}[/tex] yd.

The tire has a diameter of 33 inches. If the tire rotates one time, about how many inches will the tire travel?
Given:
Diameter of a tire = 33 inches.
To find:
The distance covered by the tire if it rotates one time.
Solution:
We have,
Diameter of a tire = 33 inches.
Radius is the half of diameter. So, the radius of the tire is
[tex]\dfrac{33}{2}=16.5[/tex]
Thus, r = 16.6 inches.
We have to find the distance covered by the tire if it rotates one time. It means, we need to find the circumference of the tire.
[tex]C=2\pi r[/tex]
[tex]C=2(3.14)(16.5)[/tex]
[tex]C=103.62[/tex]
Therefore, the distance covered by the tire if it rotates one time is 103.62 inches.

(4x+12) = 90
Step-by-step explanation:
Notice the denoted right angle at the very top left. This means those intersecting lines are perpendicular forming 90 degree angles. All right angles are equal in measure so all 4 angles at the top are 90 degrees. We can then use corresponding angles to know that all of the bottom 4 angles are also 90 degrees. Now we can solve for x. (4x+12) =90. 4x= 78. X= 19.5

C: 24 = [tex]w^{2}[/tex] + 3 (the yellow option)
Step-by-step explanation:
We can see that 24 obviously represents our total area, we are told that the rug is 3 feet LONGER THAN it is wide, suggesting that addition will be involved.
In conclusion the most logical answer would be C: 24 = [tex]w^{2}[/tex] + 3
After taxes, Liza makes $2,185.76 each month. From that, she has to pay three bills. For the last month, one bill is for $73.49, another is for $897.19, and the third is for $474.31. How much money does she have left to spend for the month?
Answer:
the amount left to spend is $740.77
Step-by-step explanation:
The computation of the amount left to spend is as follows:
= Each month payment - last month payment bills
= $2,185.76 - $73.49 - $897.19 - $474.31
= $740.77
Hence, the amount left to spend is $740.77
We simply deduct three amount bills from the each month payment

Question:
x + 3 < 5, Find x.
Answer
⟹ x + 3 < 5
( Subtracting 3 from both the sides of the inequality )
⟹ ( x + 3) - 3 < 5 - 3
⟹ x < 5 - 3
⟹ x < 2
It means that any number that is smaller than 2 will satisfy the inequality.

In the diagram below shows the cross section of a bridge with a semi circle hole. If the perimeter of the cross section is 24m. Calculate
B. Area of the cross section ( π =22/7)
Answer:
the area is 85.239 m²
Step-by-step explanation:
perimeter of a semi circle = ½πd
24 = ½ x 22/7 × d
24 x 7/11 = d
15.27 m = diameter...
area = ½πr²
= ½ × 22/7 x 7.365 x 7.365
= 85.239 m2

Find the break-Even point for the following fuctions c(x)=10x and r(x)=210-4x
Answer: The break-even point is x = 15
Step-by-step explanation:
We have the equations:
c(x) = 10*x
r(x) = 210 - 4*x
I suppose that c(x) is the cost equation, and r(x) is the revenue equation.
"break-even" means that you don't lose nor win anything, then the difference between the revenue and the cost is 0.
Then we need to solve:
r(x) - c(x) = 0
(210 - 4*x) - (10*x) = 0
210 - 4*x - 10*x = 0
210 - 14*x = 0
210 = 14*x
210/14 = x
15
This means that for x = 15, you break even.
