The two angles given are vertical angles which mean they are the same.
x +40 = 60
Subtract 40 from both sides:
x = 20
Answer:
x=20
Step-by-step explanation:
These are verticle angles, meaning the two should equal one another. If one angle is 60, its vertical angle is x+40.
x+40=60
x=20 (subtract 40 from both sides)

Question 1
Tell whether the angles are complementary or supplementary. Then find the value of x.
The angle is complementary but I don't know the value of x.
the angles are
x and (x-20)
Answer:
55
Step-by-step explanation:
If they're complementary, that means they add up to 90 so:
x + x - 20 = 90
Then, solve.
[tex]2x - 20 = 90\\2x = 110\\x= 55[/tex]
In the coordinate plane, point W is located at (-11,35). If point W is reflected across the x-axis, what are he new coordinates
Answer:
The new coordinates are (-11, -35)
Step-by-step explanation:
When reflecting across the x-axis, you are just the Y. value. It is the opposite due to the fact that if you're moving something across the horizontal x-axis, it's actually the vertical height changing. So, you just inverse the Y value to its' negative or positive reciprocal.

A ski shops rents skis and snowboards. When they first opened, they rented 11 pairs of skis to 3 snowboards. After snowboarding became an olympic sport, they noticed they were renting 5 pairs of skis to every 9 snowboards. If they rented 45 snowboards originally, how much pairs do they rent after the olympic?
Answer:
25
Step-by-step explanation:
Given that they rented 11 pairs of skis to 3 snowboards originally
And rented 5 pairs of skis to 9 snowboards after the Olympic
Then if they rented to 45 snowboards originally, then they must have rented 45/3×11 skis = 165 pairs of skis
After the Olympic, they must have rented 45/9×5 skis= 25 pairs of skis

0
6
Step-by-step explanation:
Each space between 2 lines represent 6 units. (from -6 to 0 is 6 units, from 0 to 6 is 6 units)
Since the blue dot is 3 spaces to the right of 0, it is 3 * 6 units = 18.
The value of the blue dot is 18.

plz help
Answer:
(10,30)
x=10
y=30
Step-by-step explanation:
Looking at the first one we know exactly what y is equal to in terms of x so whenever we need a y in the second equation we can just replace it with 3x which means we have
-.5x+35=3x
Solve for x and get
35=3.5x
10=x
We can then plug this x value into the first equation and solve for y
y=10*3
y=30
our answer is therefore (10,30)
Answer:
x = 10; y = 30
Step-by-step explanation:
1. Plug the 3x from the first equation into the second equation to substitute the y.
-1/2x + 35 = 3x.
2. Subtract 3x from both sides. Then subtract 35 from both sides.
-7/2x = -35
3. Multiply by the reciprocal
x = 10
4. Plug in 10 as the x in the first equation
y = 3(10)
y = 30
3. Consider this scatter plot.
Test Scores in Relation to Homework
Hours of Homework
(a) Is the relationship linear or not linear? Justify your response.
(b) Is the relationship increasing or decreasing? Find the slope and use it to help justify your answer.
(c) Paul uses the function y = 7x + 30 to model the situation. What score does Paul’s model predict for 3 hours of homework? Hint: It’s _not_ asking you to use the graph.
(d) Describe what the number 30 in Part (c) mean in the context of the situation? Hint: Think about what kind of function equation you have in Part B.
Answer:
Part A)
Part B)
Part C)
Part D
Answer:
Linear ;
Increasing ;
51 ;
Kindly check explanation
Step-by-step explanation:
The relationship between homework a d test scores is linear, this can be deduced based on the straight trend line which could be drawn through the points on the scatter plot.
The relationship is increasing, the linear trend is positive ; also from the function derived for the plot, the slope Coefficient is positive.
C.)
Given the plot function :
y = 7x + 30
The score for 3 hours of homework :
x = 3
y = 7(3) + 30
y = 21 + 30
y = 51
Test score = 51
D.) 30 represents the intercept vamie of the graph, the value of y when x = 0 ;
With respect to the context, it means the test score for a student with 0 hours of homework (student with no homework hours at all). Will be 30.

As the earth rotates, it travels a distance of 80 miles in 5 minutes. At this constant rate, which equation best represents y, the total distance the earth travels in x minutes?
Answer:
y=16x
Step-by-step explanation:
So, you are given the equation as if y=total distance the earth travels in x minutes. If you are given that you travel 80 miles in 5 minutes, you can plug these value into the variables they are representing and solve for the constant.
Visual:
y=xk y=miles x=minutes k=constant
Plug in your values and you get:
80=5k
Now, you solve for k by diving 5 on both sides, which leaves you with k=16.
Now you plug your value for k into the original equation, leaving you with y=16x
what is the formula for elimintation
Answer:
The elimination method for solving systems of linear equations uses the addition property of equality. You can add the same value to each side of an equation. So if you have a system: x – 6 = −6 and x + y = 8, you can add x + y to the left side of the first equation and add 8 to the right side of the equation.
Answer:
You can add the same value to each side of an equation. So if you have a system: x – 6 = −6 and x + y = 8, you can add x + y to the left side of the first equation and add 8 to the right side of the equation.

Find the ratio of a:b:c in the simplest form.
a: b = 2:9 and b: c = 2 : 3
Answer:
a : b : c = 4 : 18 : 27
Step-by-step explanation:
a: b = 2:9 and b: c = 2 : 3
a : b = 2*2 : 9*2 = 4 : 18
b : c = 2*9 : 3*9 = 18 : 27
a : b : c = 4 : 18 : 27

If AABC ~ ADEC, find the value of x and y.
Answer:
please mark the brainliest❤❤
Step-by-step explanation:
[tex] \frac{6}{21} = \frac{x}{28} = \frac{10}{y} [/tex]
(6×28)÷21=8
(28×10)÷8=35
so x=8
y=35
The value of x is 8 units and y is 35 units.
What is Similarity?In geometry, two similar forms are those whose dimensions are identical or have a same ratio but the size or length of their sides differ. Examples include similar triangles, similar rectangles, and similar squares.
Given:
ΔABC ~ ΔDEC
Then, AB/ DE = BC / EC = AC/ DC
So, AC/ DC = AB/ DE
x / 28 = 6 / 21
x / 28 = 2/ 7
x= 8 units
and, BC / EC = AB/ DE
10 / y = 6/21
10/ y = 2/7
2y= 70
y= 35 units
Hence, the value of x is 8 units and y is 35 units.
