Answer:
[tex]x = 11[/tex]
Step-by-step explanation:
Given
The attached triangle
Required
Find x
The theorem that applies to this question is the theorem of external angles. And it translates to:
[tex]11x +2 = 58 + 5x + 10[/tex]
Collect Like Terms
[tex]11x -5x = 58 + 10-2[/tex]
[tex]11x -5x = 66[/tex]
[tex]6x = 66[/tex]
Divide through by 6
[tex]\frac{6x}{6} = \frac{66}{6}[/tex]
[tex]x = \frac{66}{6}[/tex]
[tex]x = 11[/tex]

"a line intercepts the point (3, -4) and has a slope of 17. what is the slope-intercept equation for this line?"
then it has the partially filled out equation:
y=17x+__
Answer:
-55 = b
Step-by-step explanation:
If you fill in the x and the y with the equation you have below, you would get:
-4 = 17(3)+b
Multiply 17 and 3
-4 = 51 + b
-55 = b
Answer:
y=17x-55
Step-by-step explanation:
4 = 17(3)+b
-4 = 51 + b Subtract 51 both sides
-55 = b
Hope this helps :)
Find the measures of the angles in a triangle with the ratio of 2:7:9
Answer: 20, 70, 90
====================================================
Work Shown:
Let x be some positive real number.
Multiply each part of the given ratio by x to get 2x:7x:9x
So we have the three angles 2x, 7x, and 9x.
For any triangle, the three angles must add to 180
2x+7x+9x = 180
18x = 180
x = 180/18
x = 10
This leads to
2x = 2*10 = 207x = 7*10 = 709x = 9*10 = 90The three angles of this triangle are: 20, 70, 90
This is a right triangle due to the 90 degree angle.

Answer:
1200 cubic units
Step-by-step explanation:
If you split the shape into two parts, you can find the volume of each and solve. For the first part, you do 10x8x6 to get 480. For the second part you do 12x10x6 to get 720. Add 480+720 to get 1200.

You earn $28 for washing 4 cars. How much do you earn for washing 3 cars?
Answer:
21 dollars
Step-by-step explanation:
Answer:
$21
Step-by-step explanation:
Make the original statement into a ratio.
$28/4
Simplify the fraction above.
$28/4 = 7
So, you earn $7 per car you wash.
As a result, you multiply $7 by the number of cars the question is asking you for. In this case it is 3 cars.
So, you multiply 7 x 3
7 x 3 = 21
Therefore, you will earn $21 for washing 3 cars.

Solve for X
9x + 8 = -1
Answer:
x = -1
Step-by-step explanation:
9x + 8 = -1
Subtract 8 from each side
9x + 8-8 = -1-8
9x = -9
Divide each side by 9
9x/9 = -9/9
x = -1

Jason is baking a cake. The recipe calls for 2 cups of sugar for every 5 cups of flour. If he is making a small cake and is only using 1 cup sugar, how many cups of flour should he use? *
Answer:
2 1/2 cups
Step-by-step explanation:
First, our ratio is sugar:flour or 2:5, so our question is 1:? We find ? by finding how we got to 1 on the other side.
2 ÷ 2 = 1
And what we do to one side, we always have to do to the other to make it proportional, so
5 ÷ 2 = 2.5 or 2 1/2
So, if Jason is using 1 cup of sugar, he should use 2 1/2 cups of flour
hope this helps

Hi, this expression is not solvable because we can just literally substitute anything with x. You cannot solve an expression, unless given a value. However, you can solve an equation. In this case, it is an expression.
NEED HELP WITH THIS
Answer:
Step-by-step explanation:
think of this as a system of equations where the colors just represent a variable like x or y
I'll just arbitrarily set colors to some variable letter so we have
purple = x
green =y
blue =z
red = a
yellow = b
so we can now rewrite the 4 known equations of the system :)
Eq. 1) x+y = 13
Eq. 2) 2y+2z=18
Eq. 3) 2x+3y=31
Eq. 4) z + 4a = 12
Eq. 5) a * y = b
so solve the 1st eq for y => y =13-x then plug that into the 3rd eq and slove for x => 2x + 3(13-x) =31
2x + 39 -3x = 31
2x-3x = 31 - 39
-x = -8
x=8
plug 8 into Eq. 1 for x and solve for y
8+y = 13
y=5
plug y into Eq 1 and solve for z
2(5) +2z = 18
10 +2z = 18
2z = 8
z = 4
plug z into E1 4 and solve for a
4 + 4a = 12
4a = 8
a = 2
plug a and y into Eq 5 and solve b
2 * 5 = b
10=b

An architect builds a model of a park in the shape of a rectangle. The model is 40.64 centimeters long and 66.04 centimeters wide. One inch equals 2.54 centimeters. Use the ratio table to find the ratio of the length to the sum of the length and width in inches and in simplest form.
Answer:8: 21
Step-by-step explanation:
Given : An architect builds a model of a park in the shape of a rectangle. The length of the model = 40.64 centimeters
The width of the model = 66.04 centimeters
Since, .
Then ,
Now, the length of the model =
The width of the model =
Sum of length and width = 16+26=42 inches
Now, the ratio of the length to the sum of the length and width in inches :_
Hence, the ratio of the length to the sum of the length and width in inches in simplest form = 8:21
