Answer:
27°
Step-by-step explanation:
when you see a square to represent that angle, that means that angle is 90 degrees (a right angle)
the angle of a straight line is 180
so [tex]180-90=90[/tex]
[tex]3x+9=90[/tex]
[tex]3x=81[/tex]
[tex]x=27[/tex]

Answer:
x ≥ 4; solid circle at 4 and shaded to the right
Step-by-step explanation:
Given:
x +2 ≥ 6
Subtract 2
x +2 -2 ≥ 6 -2
x ≥ 4
This is graphed as a solid circle at x=4 and shaded to the right (where x > 4).

Answer:
StartFraction 1 centimeter over 2.5 meters EndFraction = StartFraction 12 centimeters over x meters EndFraction
Step-by-step explanation:
The complete question is
Eveline made a scale drawing of a patio she is planning to build.
1 centimeter = 2.5 meters. Triangle A B C. Side A is 12 centimeters, side B is 5 centimeters, and side C is 13 centimeters.
Which proportion could Eveline use to find the length of side A?
StartFraction 1 centimeter over 2.5 meters EndFraction = StartFraction 13 centimeters over x meters EndFraction
StartFraction 1 centimeter over 2.5 meters EndFraction = StartFraction 12 centimeters over x meters EndFraction
StartFraction 12 centimeters over 2.5 meters EndFraction = StartFraction x centimeters over 1 meter EndFraction
StartFraction 1 centimeter over 12 meters EndFraction = StartFraction 2.5 centimeters over x meters EndFraction
The picture of the question in the attached figure
we know that
The scale drawing is
That means
1 cm in the drawing represent 2.5 m in the actual
using proportion
Find out the actual length of side A if in the drawing the length is 12 cm
solve for x
The length of side A is 30 meters
The answer is B

A. [tex]y=\frac{3}{2}x-1[/tex]
B. [tex]y=\frac{3}{2}x[/tex]
Step-by-step explanation:
For the graph shown, the slope is [tex]\frac{3}{2}[/tex] and the y-intercept is -1. For the new line, it would have the same slope, but would have a y-intercept of 0.
The graph shows the total money earned at a
fundraising car wash. Which equation can be
used to find the total earned y for the number of
cars washed .x?
Answer: C
Step-by-step explanation
You have to divide the output, which in this case is Y (5), into the input, also known as X (1). You will then get your answer, which is 5 dollars per car. To put that into an equation, it will be: y = 5x.
Here is the work:
5(y) ÷ 1(x) = 5
y = 5x
Answer:
Answer c is correct

Replace x with 11 and solve:
4(3(11) + 5)
3 x 11 = 33:
4(33 + 5)
33 + 5 = 38:
4(38)
4 x 38 = 152
answer: 152

Answer:
70 degrees
Step-by-step explanation:
2x+3x-20+x+20=180
( angles in a triangle add up to 180 degrees)
as you want to find one x you need to move everything else to the other side: first collect all the like terms: 6x=180
in order to find x you need to divide 180 by 6 which is equal to 30
therefore x=30
if you substitute this into XYZ it would be: 3(30)-20
90-20=70
therefore XYZ=70 degrees
Hope this helped
Answer:
70
Step-by-step explanation:
So we know that the angles of a triangle equal up to 180 degrees. So let's make an equation. So we can do:
2x+(3x-20)+(x+20) = 180
Simplify:
6x=180
x=30
We can also plug this in to check our work. So it would be:
60+(90-20)+(30+20)
simplify
70+50+60=180
Then we have to find angle XYZ so we do 90-20=70

The figure shows three quadrilaterals on a coordinate grid
Which of the following statements is true about the three quadrilaterals
Answer:
Hello! Elizabeth is here! The answer to your question is 3) M and N are similar but not congruent!
Step-by-step explanation:
As you can see on the coordinate grid, the M is at the (-4,3) and the N is at (4,1/2) , both M & N are similar from it size, sure but their coordinate location is quite different, or should I say M & N is not similar with congruent.
Hope this helped and have a wonderful day!

What is the answer to this?
Answer:
132 units²
Step-by-step explanation:
The figure is a trapezoid, so its area can be found using the formula for the area of a trapezoid.
A = 1/2(b1 +b2)h
The top "base" is the difference between 21 units and 9 units, so is 12 units. Filling in the numbers, we have ...
A = 1/2(21 units +12 units)(8 units) = 132 units²
The area of the figure is 132 square units.
What id the answer to this question?
Answer:
14
Step-by-step explanation:
On the top layer, there is one cube, on the layer below it there is 3, plus the one under the cube is 4. Then on the very last layer, there is 5, plus the 4 under the cubes is 9, so 9 + 4 + 1 = 14
Answer:14
Step-by-step explanation:first you count up the bottom to the to then that is your bottom answer which is 9 then you count up the ons above it which will be 4 that is your middle answer then there is one at the top add up them all and that is your answer 14.
