Answer:
by using substuton method
2x=22-y
x=22-y/2 equation (i)
so substuting the value x in x-y=5
22-y/2-y=5
22-y-2y/2=5
22-3y=10
22-10/3=y
12/3=y
4=y
now substitute the value of y in equation (i)
x=22-y/2
=22-4/2
=18/2
=9
therefore ,the value of x is 9 and y is 4

Drag the green point on the tape diagram to model a discount of 27%.
If the discount is 27%, then what percent of the original price do you pay?
Answer:
73%
Step-by-step explanation:
Let us have the original price as $100
A discount of 27% will be;
27/100 * 100 = $27
so, the value to be paid will be $100 - $27 = $73
Now, what percentage of $100 is the $73 that was paid
that would be;
73/100 * 100% = 73%
5 (x + 8) = -10 what's the answer
Answer:
x = - 10
Step-by-step explanation:
5(x + 8) = - 10
5x + 40 = - 10
5x + 40 - 40 = - 10 - 40
5x = - 50
5x ÷ 5 = - 50 ÷ 5
x = - 10
if u subtract 12 from a number and multiply the result by 12 you get 18. what is the number
Answer:
27/2 is the value of the number.
Let the number be x.
According to the question,
12(x-12)=18
x-12=18/12
x-12=3/2
x=3/2+12
x=3/2+24/2
x=27/2

Answer:
13.5 27/2 13 (1/2) all the same
Step-by-step explanation:
(x-12)x12 = 18
12x-144 = 18
12x = 162
x = 162/12 = 27/2 = 13(1/2) = 13.5

A tire has a circumference of 69.1 inches. To the nearest inch, which is the diameter
of the tire?
Answer:
22 inches
Step-by-step explanation:
so to find the diameter you divide the circumference by pi(3.14)
69.1÷3.14=22.006

Answer:
R'=(-3,6)
Q'=(-3,-3)
S'=(7,6)
T'=(7,-3)
Answer:
see explanation
Step-by-step explanation:
A translation of 7 units right means adding 7 to the x- coordinate. The y- coordinate remains unchanged, then
Q (- 10, - 3 ) → Q' (- 10 + 7, - 3 ) → Q' (- 3, - 3 )
R (- 10, 6 ) → R' (- 10 + 7, 6 ) → R' (- 3, 6 )
S (0, 6 ) → S' (0 + 7, 6 ) → S' (7, 6 )
T (0, - 3 ) → T' (0 + 7, - 3 ) → T' (7, - 3 )
Maya owns a house valued at $432,600. She still owes $233,458 on her mortgage. How much equity does she have in the house? (3 points)
Answer:
$199,142
Step-by-step explanation:
Given that
The value of the house i.e. assets is $432,600
The mortgage i.e. liability is $233,458
We need to find out the equity
As we know that
The accounting equation is
Total assets = Total liabilities + total equity
$432,600 = $233,458 + total equity
So, the total equity is
= $432,600 - $233,458
= $199,142
Answer:
No, she is not correct. She has only $30,000 in home equity. Equity is the value of ownership in an asset minus any debts owed on it. $315,000 minus $285,000 is $30,000.

A company that makes robotic vacuums claims their newest model of vacuum lasts, on average, two hours when starting on a full charge. To investigate this claim, a consumer group purchases a random sample of five vacuums of this model. They charge each unit fully and then measure the amount of time each unit runs. Here are the data (in hours): 2.2, 1.85, 2.15, 1.95, and 1.90. They would like to know if the data provide convincing evidence that the true mean run time differs from two hours. What are the appropriate hypotheses?
H0: μ = 2 versus Ha: μ < 2, where μ = the true mean run time for all vacuums of this model
H0: μ = 2 versus Ha: μ > 2, where μ = the true mean run time for all vacuums of this model
H0: μ = 2 versus Ha: μ ≠ 2, where μ = the true mean run time for all vacuums of this model
H0: μ ≠ 2 versus Ha: μ = 2, where μ = the true mean run time for all vacuums of this model
Answer:
The answer is C. H0: μ = 2 versus Ha: μ ≠ 2, where μ = the true mean run time for all vacuums of this model

Solve for w by simplifying both sides of the equation, then isolating the variable.
Exact Form: w = 7 2 w = 7 2
Decimal Form: w = 3.5 w = 3.5
Mixed Number Form: w = 3
final answer: choice Bb. 3.5
Step-by-step explanation:The choices are:
a. 3
b. 3.5
c. 4
d. 4.5
The equation is 5 = w + [tex]1\frac{1}{2}[/tex]
5 - [tex]1\frac{1}{2}[/tex] = [tex]3\frac{1}{2}[/tex]
w = [tex]3\frac{1}{2}[/tex]
[tex]3\frac{1}{2}[/tex] converted into a decimal equals 3.5
So the correct answer is b. 3.5

Find the measure of the missing angle.
Answer: a= ______
(NO FILES) IF YOU ANSWER YOU WILL BE MARKED BRAINLIEST :)
Answer:
a= 32
Step-by-step explanation:
Since "a" is a part of a supplementary angle (An angle that adds up to 180º)
What you would need to do is add 58º and 90º (90º because the right angle = 90)
so 58+90 = 148
Then you would subtract 148 from the total of the angle (Which is 180)
so 180 - 148 = 32, And that shows that a = 32

Find the measure of angle 1, 3, and 4.
Answer:
1) 60
3) 120
4) 60
Step-by-step explanation:
Angle 1 is supplementary to your known angle. Therefor, Angle 1 is 180 - 120
Angle 3 is supplementary to Angle 1 and equal to 120
Angle 4 is supplementary to Angle 3 and equal to angle 1.
Find the area of the combined rectangles. Please help me
Answer:
8: 190 yd , 9: 30 m, 10: 92 ft
Step-by-step explanation:
for 8, you can spit it up pretty simply. find 10x18 which is 180 and then 5x2 which is 10 so 8 is 190.
for 9, 2x8=18 for the top portion and for the sides 3x2=6, so twelve. Combined its 30m.
for 10, 10x8=80, then 6x2=12. so 92 ft combined.

Complete the square to find the vertex of this parabola. x2-16y-4x-12=0
Answer:
Step-by-step explanation:
x^2-16y-4x-12=0
Transpose and separate x and y
16y = x^2-4x-12
16y = (x^2-4x+4) -16
16y = (x-2)^2 -16
y = (1/16)(x-2)^2 -1
This means that the vertex is at
(x-2)=0 or x=2
y = -1
=> vertex (2,-1)

Answer:
[tex]5\sqrt{3}[/tex]
Step-by-step explanation:
A triangle with angles of 30-60-90 will always have sides that measure in the following proportions:
The side opposite the 30* angle = a
The side opposite the 60* angle = [tex]a\sqrt{3}[/tex]
The side opposite the 90* angle = 2a
(I used "a" here because your question uses "x" and I don't want to confuse things, but usually people use "x" rather than "a")
They gave us that the hypotenuse (the side opposite the 90* angle) is 10, from there we can figure out the other sides:
Since the side opposite 90* is 2a, and 2a = 10, divide 10 by 2 and you get a = 5.
Once we know what "a" is, we can fill in the rest:
30* = 5
60* = [tex]5\sqrt{3}[/tex]
90* = 10
