Answer:
y is x - 5.
Step-by-step explanation:
x - y = 5
x = y + 5
we can isolate y by subtracting 5 from both sides of the equation:
x = y + 5
x - 5 = y
Therefore, the solution for y is x - 5.

One side of a square has a measurement of 2x + 4. Write an expression to represent the perimeter of the shape.
Answer:
4(2x+4)
for example, if 5 were the length of a side you'd do 4(5). 4 because theres 4 sides and the formula for P is P= l+l+w+w OR P=2l+2w
Math sucks helppppp pls
Answer:
B
Step-by-step explanation:
Perimeter of the composite shape = ½ of the circumference of a circle + perimeter of a rectangle - Length of the rectangle
= ½*2πr + 2(L + W) - L
Where,
r = 8
π = 3.14
L = 16
W = 12
Perimeter of the composite shape = ½(2*3.14*8) + 2(16 + 12) - 16
= 25.12 + 56 - 16
Perimeter of the composite figure = 65.12 inches
Area of the composite figure = ½(πr²) + L*W
= ½(3.14*8²) + 16*12
= 100.48 + 192
Area = 292.48 square inches
Classify the polynomial according to its degree and number of terms 8x.
quadratic binomial
seventh-degree binomial
seventh-degree monomial
linear monomial
Answer:
Linear monomial
Step-by-step explanation:
As here the number of terms is only 8x that is only one hence it is a monomial and as its degree here is 1 hence it is linear.
So it is a linear monomial.

the map below shows certain locations in town. Use the map and the box of equations at the right to answer the questions below.
Step-by-step explanation:
Gas Station (2,7) -> y = [tex]\frac{1}{2}[/tex]x + 6 if you plug in the numbers it becomes 7 = 1 + 6
Grocery Store (6,3) -> x + 6y = 24 plug in the numbers it becomes 6 + 18 = 24
Bowling Ally (1, -3) -> 6x + 3y = -3 plug in numbers 6 -9 = -3
Movies (7, -7) -> y = -7 because the y coordinates for the movies = -7
Park(-2, -4) -> -6x + 2y = 4 plug in the numbers 12 - 8 = 4
Coffee Shop (-6, -8) -> -10x + 5y = 20 plug in the number 60 - 40 = 20
Gym (-8, -3)-> y = - [tex]\frac{1}{2}[/tex]x - 7 plug in the numbers -3 = 4-7
School (-6, 6) -> y = - [tex]\frac{1}{3}[/tex]x +4 plug in the numbers 6 = 2 + 4
6x + 3y = -3 quadrant II is (-x, y)
rearrange the equation:
3y = -6x - 3
y = -2x - 1
if x is -1, y will be 2 -1 = 1. So another solution for this equation is (-1, 1).

6a2−11a+9=0
What is the number of real solutions?
Select the correct answer below:
0
1
2
Answer:
0
Step-by-step explanation:
Use discramnt formula
[tex]b {}^{2} - 4ac[/tex]
Where 6 is a, 11 is b and 9 is c
[tex]11 {}^{2} - 4(6)(9) [/tex]
[tex]121 - 216 = - 95[/tex]
Since the discramnt is negative, there are no real solutions and it will only produce imaginary solutions
I dont understand it
Answer:
30xy
Step-by-step explanation:
I divided this shape into a square and a rectangle.
Solve:
First I multiplied 2x and 3y
2x*3y= 6xy
Then I multiplied 6x and 4y
6x*4y= 24xy
Then I added them together
24xy+6xy= 30xy

HA < CH
HM > CH
AM = CK
MH < HC
Answer:
HM > CH
Step-by-step explanation:
You are correct, I didn't see the option HM > CH, which is correct, since the angle 90 degrees is larger than the angle 73, and then the sides opposite to them must follow suit.
Therefore, the correct answer is: HM > CH
The true statement from the triangles is (b) HM > CH
How to determine which must be trueFrom the question, we have the following parameters that can be used in our computation:
The figures
Next, we have
Angles at corresponding points = 90 degrees and 73 degrees
Since the angle 90 degrees is larger than the angle 73 degrees, and then the sides opposite to them must also have the same relationship
Using the above as a guide, we have the following:

se quiere pintar una pared en forma de hexágono regular y se sabe que cada lado mide 3m y que su apotema es de 2,8m cual es el area que se va a pintar?
Answer:
El área total a pintar será:
[tex]A_{tot}=25.2\: m^{2}[/tex]
Step-by-step explanation:
Sabiendo el apotema y la longitu de los lados, podemos encontrar el área de un triangulo. Recordemos que, si trazamos rectas del centro del hexágono a los vértices, se formaran 6 triángulos equiláteros.
El área de un triángulo es:
[tex]A_{t1}=\frac{b*a}{2}[/tex]
b es la longitud de la base (b=3 m)
a es la apotema, osea la altura del triangulo (a = 2.8)
[tex]A_{t1}=\frac{2.8*3}{2}[/tex]
[tex]A_{t1}=4.2\: m^{2}[/tex]
Ahora, solo debemos mutiplicar ese valor por 6 para determianr el área total de la pared.
[tex]A_{tot}=25.2\: m^{2}[/tex]

Nine years ago, Tarah opened a savings account with her bank. She started with a balance of $450 and has not made any withdrawals or deposits since then.
If her interest rate is 7% each year, how much interest has accrued using simple interest?
Answer:
Step-by-step explanation:
The interest accrued is $258.48.
Step-by-step explanation:
Given that:
Initial balance in the savings account = $359
Interest rate = 8%
Time for which no withdrawals or deposits were done = 9 years
To find:
Simple Interest accrued = ?
Solution:
First of all, let us have a look at the formula for simple interest.
Where P is the Principal Amount.
R is the annual rate of interest
T is the time in years.
Here, we are given:
P = $359
R = 8%
T = 9 years
Let us put all the values in the formula:
So, the interest accrued is $258.48.

D.y=- 1/5x
E. Y=5x
F.y=x
Answer:
D. y=-1/5(x)
Step-by-step explanation:
To find the equation of a line, use the formula y=mx+b, where x and y represent your x and y coordinates, m is your slope and b is your y-intercept.
b is you y-intercept, this is where the line cuts the y-axis. We can see from the graph that the line cuts the y-axis at (0,0), so c=0.
Now we have y=mx
Sub in one of our points (10,-2):
-2=m10
m=-1/5
So our equation looks like this:
y=-1/5(x)

Martha's bakery started with 200 cupcakes in the morning. After a busy afternoon there were only 60 cupcakes left. By what percent did the cupcake inventory drop?
Answer: 70%
Step-by-step explanation:
Martha's bakery started with 200 cupcakes in the morning and after a busy afternoon there were only 60 cupcakes left, this means that 200 - 60 = 140 cupcakes were sold.
The percentage drop will be:

Jenny read 12 pages on Monday, 25 pages on Tuesday and
the remaining pages on Wednesday. On average she read
23 pages per day during these three days. How many pages
did she read on Wednesday?
Answer:
32
Step-by-step explanation:
Let Wed pages = x
(12 + 25 + x) / 3 = 23 Multiply both sides by 3
12 + 25 + x = 3 * 23 Combine the right
12 + 25 + x = 69
37 + x = 69 Subtract 37
x = 69 - 37
x = 32
32 pages were read on Wed

The difference of four times a number and seven is 21. Find the number.
Answer:
7
Step-by-step explanation:
4x-7=21
4x=28
x=7.....
The number is 7.
We have a sentence - "The difference of four times a number and seven is 21".
We have to find the number.
Express the statement - "The difference of 40 and 20 is equal to n" in the form of expression.The expression representing the above statement is -
n = 40 - 20 = 20
According to the question, we have -
The difference of four times a number and seven is 21.
Assume the number be x.
Therefore -
4x - 7 = 21
4x = 28
x = 7
Hence, the number is 7.
