Answer:
r<2r>-5Step-by-step explanation:
Subtract 8 from both sides.Simplify.Add 2r to both sides.Simplify. Divide both sides by 4.Simplify 8/4 to 2.Subtract r from both sides.Simplify.Subtract 21 from both sides.Simplify.Divide both sides by 6.Then Simplify 30/6 to 5.In biology class, Kaylee observes cells.

Scarlett and Alyssa work at a dry cleaners ironing shirts. Scarlett can iron 15 shirts per hour, and Alyssa can iron 35 shirts per hour. How many total shirts would be ironed between the two workers if Scarlett worked 5 hours and Alyssa worked 10 hours on a given day? How many total shirts would be ironed between the two workers if Scarlett worked x hours and Alyssa worked y hours on a given day?
Answer:
25x + 35(2x) = 380
25x + 70x = 380
95x = 380 so
x = 4
then i think that mean it might be 8 then im not completly sure

Find two integers whose sum is 10 and product is 9
Answer:
let the numbers be x and y then by given conditions:
x + y = 10 ….. eq 1
and
xy = 9….. eq 2
from eq 2. y = 9/x
put this in eq. 1
x + 9/x = 10
x + 9= 10x
x = 1
now,
xy = 9put value of x
y = 9

Sarah is having people over for her birthday party. If she orders 4 pizzas for 15 people, how many should she order for 30 people?
Answer: 8
Step-by-step explanation:
Answer: 8 pizzas.
Step-by-step explanation:If she is ordering 4 pizzas for 15 people then that simply means that the fraction is 4/15, 15*2 is 30, so that means that our next fraction (Equivalent fraction) will be like this 4/15 = -/30. What ever. Happens to the numerator must happen to the denominator and vice versa. So 4*2 is 8. So the answer is 8.

Mr. Suárez wants to paint his storage shed. He needs to calculate the lateral surface area of the shed so
that he will know how much paint to buy. The shed is in the shape of a rectangular prism with the
dimensions shown below.
9 Ft
6 ft
12 ft
A. 162
B. 234
C. 648
D. 324
Answer:
Lateral surface area of the storage shed = 336 ft²
Step-by-step explanation:
The shed is in the shape of a rectangular prism. The lateral surface area of the storage shed can be calculated below. The lateral area is the sides of the prism.
lateral area of a rectangular prism = 2h (l + w)
where
l = length
h = height
w = width
h = 8 ft
l = 14 ft
w = 7 ft
lateral area of a rectangular prism = 2h (l + w)
lateral area of a rectangular prism = 2 × 8 × (14 + 7)
lateral area of a rectangular prism = 16 (21)
lateral area of a rectangular prism = 336 ft²
Lateral surface area of the storage shed = 336 ft²

Write an exponential decay function to model the situation in the photo.
Correct answer will get a Brainliest, a 5star rating, and a Thanks !
Step-by-step explanation:
The formula for exponetial equation decay is
[tex]y = a(b) {}^{x} [/tex]
where a is the initial value and b is the decay factor.
A will be 56 since that our initial value.
b will be 0.9 since we are constantly decaying by 0.9.
so our equation is
[tex]y = 56(0.9) {}^{x} [/tex]

Determine if the triangles are congruent. If they are, state why.
Is this pair of triangles congruent if so what theorem applies to describe the series of rigid motions
Answer:
yes; The triangles are congruent by hypotenuse-angle congruence.
Step-by-step explanation:
Answer: yes Question 6
There is not enough information to determine congruency
Question 9
yes; The triangles are congruent by hypotenuse-leg congruence
Step-by-step explanation:
* Lets revise the cases of congruence
- SSS ⇒ 3 sides in the 1st Δ ≅ 3 sides in the 2nd Δ
- SAS ⇒ 2 sides and including angle in the 1st Δ ≅ 2 sides and
including angle in the 2nd Δ
- ASA ⇒ 2 angles and the side whose joining them in the 1st Δ
≅ 2 angles and the side whose joining them in the 2nd Δ
- AAS ⇒ 2 angles and one side in the first triangle ≅ 2 angles
and one side in the 2ndΔ
- HL ⇒ hypotenuse - leg of the first right angle triangle ≅ hypotenuse
- leg of the 2nd right angle Δ
- HA ⇒ hypotenuse - angle of the first right angle triangle ≅ hypotenuse
- angle of the 2nd right angle Δ
- LL ⇒ leg - leg of the first right angle triangle ≅ leg - leg of the
2nd right angle Δ
* Now lets solve the problem
# Question 6
- There are two right angle triangles
- They have two different legs
- There is no mention abut legs equal each other
- There is no mention about hypotenuses equal each other
- There is no mention about acute angels equal each other
∴ There is not enough information to determine congruency
# Question 9
- There are two right angle triangles
- Their hypotenuse is common
- There are two corresponding legs are equal
∵ The hypotenuse is a common in the two right triangles
∵ Two corresponding legs are equal
- By using hypotenuse-leg congruence
∴ yes; The triangles are congruent by hypotenuse-leg congruence
Step-by-step explanation:
Property 5
RHS Criterion for Congruence
Explaining the congruence of triangles using RHS Criterion of Congruence
RHS Criterion stands for Right Angle-Hypotenuse-Side Criterion.
Under this criterion, if the hypotenuse and side of one right-angled triangle are equal to the hypotenuse and the corresponding side of another right-angled triangle, the two triangles are congruent.
Important Notes
Two figures are congruent if they have the same shape and size.
Two angles are congruent if their measures are exactly the same.
Two triangles with equal corresponding angles may not be congruent to each other because one triangle might be an enlarged copy of the other. Hence, there is no AAA Criterion for Congruence.
Hope this helps have a nice day❤️
Use the drawing tools to form the correct answers on the graph.
Plot the zeros of this function:
f(x) = (x – 1)(x – 7).
Answer:
Zeros of the given function are x = 1, 7
Step-by-step explanation:
Given function is,
f(x) = (x - 1)(x - 7)
For zeros of the function,
f(x) = 0
(x - 1)(x - 7) = 0
(x - 1) = 0
x = 1
(x - 7) = 0
x = 7
Therefore, zeros of the given function are x = 1, 7
We can find the zeros by suing a graphing tool.
What is the value of x? Pls help
Answer:
x=20
Step-by-step explanation:
ok so that is a pentagon and if you didnt know all of the angles in a pentagon add up to equal 540
so we setup an equation which would be
7x+4x+5+4x+10+5x-5+6x+10=540 and now we just solve for x
step 1 combine like terms
7x+4x=11x
11x+4x=15x
15x+5x=20x
20x+6x=26x
5+10=15
15-5=10
10+10=20
now we have
20+26x=540
step 2 subtract each side by 20
20-20 cancels out
540-20=520
now we have 26x=540
the final step is to divide each side by 26
26/26 cancels out
540/26=20
x=20
hope this helps :D
SOMEONE HELP ME WITH MATH PLEASE !
Answer:
C
Step-by-step explanation:
First, eliminate choice B b/c the max is 28, not 26.
Next, lets find the median.
(12+18+20+20+24+26+28+28) = (20+24)/2 = 22
That leaves us with only A & C as a possible answer.
Q1 = The median of the first half of the data (12, 18, 20, 20)
Q1 = (18+20) / 2 = 19
A & C have the same Q1 values, so we need to compare Q3 values.
Q3 = The median of the second half of the data (24, 26, 28, 28)
Q3 = (26+28) / 2 = 27
The Correct Answer is C b/c A had a different Q3 value.

Mason opens a savings account by making a $165.85 deposit. Every week, he deposits another $20.50 in the account. The following expression shows the amount of money that will be in the account x weeks after Mason opens it.
165.85 + 20.5x
How much money will be in the account after 10 weeks?
After 10 weeks, there will be ____ $
in the account.
Answer:
370.85
Step-by-step explanation:
20.50×10. +165.85=
Answer:
$370.85
Step-by-step explanation:
He started off with $165.85. So all we need to do is multiply $20.50 x 10 = $205. We need to add 165.85 + 205 = $370.85
So after 10 weeks there will be $370.85.

Step-by-step explanation:
Determine all the transformations that have happened to f(x) = (x + 4)2 + 2 compared to
f(x) = x2
Answer:
Folow the steps to learn what transformations were determined.
Step-by-step explanation:
First we would have to graph the parent function which is f(x) = x^2. Start by finding your x and y values. Find the y values by plugging in the x values into the parent function.
X Y
2 4
1 1
0 0
-1 1
-2 4
Once these points are plotted you can start determining what are the transformations. Find the difference between the parent function and f(x) = (x + 4)^2 + 2 by looking below.
Vertical Shifts:
f(x) + c moves up,
f(x) - c moves down.
Horizontal Shifts:
f(x + c) moves left,
f(x - c) moves right.
The parent function has to be transformed left 4 and up 2. In order to do this shift each point from earlier left 4 and then up 2. In conclusion you will have two functions graphed (parent function and the transformed function).
