Answer:
5 lawns
Step-by-step explanation:
Firstly, the equation is 25x + 10 = 135
Ezri makes $25 for every lawn she mows (25x) and has an automatic $10 per day (10). In order to make $135 we take what she makes each day and set it equal to 135.
To solve, we subtract 10 from both sides to create 25x = 125. We then divide 25 from both sides to get x=5. This means that Ezri needs to mow 5 lawns in order to make $135.
I hope this is helpful to you!

Answer:
7/8 = 21/24
5/6 = 20/24
3/4 = 18/24
Step-by-step explanation:
What you do to the denominator, you do the same to the numerator.
[tex]\frac{7}{8} * \frac{3}{3} = \frac{21}{24}[/tex]
[tex]\frac{5}{6} * \frac{4}{4} = \frac{20}{24}[/tex]

Three jackets cost as much as five shirts. Each jacket costs $16 more
than each shiri. What is the cost of one shirt?
Answer:
$3.20
Step-by-step explanation:
Divide the number 16 (as in the cost per Jacket) by 5. (The amount of shirts you could buy with $16)
Then once you have divided 16 by 5, your answer should be 3.2, so the cost of one shirt is $3.20

(A) f(x) = 7 is constant, so f(x + h) = 7, too, which makes f(x + h) - f(x) = 0. So f'(x) = 0.
(B) f(x) = 5x + 1 ==> f(x + h) = 5 (x + h) + 1 = 5x + 5h + 1
==> f(x + h) - f(x) = 5h
Then
[tex]\displaystyle f'(x) = \lim_{h\to0}\frac{5h}h = \lim_{h\to0}5 = 5[/tex]
(C) f(x) = x ² + 3 ==> f(x + h) = (x + h)² + 3 = x ² + 2xh + h ² + 3
==> f(x + h) - f(x) = 2xh + h ²
[tex]\implies\displaystyle f'(x) = \lim_{h\to0}\frac{2xh+h^2}h = \lim_{h\to0}(2x+h) = 2x[/tex]
(D) f(x) = x ² + 4x - 1 ==> f(x + h) = (x + h)² + 4 (x + h) - 1 = x ² + 2xh + h ² + 4x + 4h - 1
==> f(x + h) - f(x) = 2xh + h ² + 4h
[tex]\implies \displaystyle f'(x) = \lim_{h\to0}\frac{2xh+h^2+4h}h = \lim_{h\to0}(2x+h+4) = 2x+4[/tex]

the length of a building is 720 in. Use dimensional analysis to convert this quantity to yards.
Answer:
20 yards
Step-by-step explanation:
First, we have to know how to get from inches to yards. 12 inches = 1 foot, and 3 feet = 1 yard.
Next, we have
[tex]\frac{720 in}{1}[/tex]
as a given. We want to multiply this by our conversions to get the end amount in yards.
We can first multiply our expression by 12 inches = 1 foot. To do this, we can set one number as the divisor and one as the dividend, e.g. 12 inches / 1 foot. However, to figure out which number should be the numerator/denominator, we first must examine our original expression. We want to multiply it by a value that cancels something out in conversion. To do this, we can have the same unit of something in the numerator in one and the denominator in the other in terms of what we're multiplying. Here, we can see that [tex]\frac{720 in}{1}[/tex] has inches on the top, so we want inches on the bottom in 12 inches = 1 foot. Therefore, we have
[tex]\frac{720 in}{1} * \frac{1 foot}{12 inches}[/tex]
= [tex]\frac{720feet}{12}[/tex]
= 60 feet
= [tex]\frac{60 feet }{1}[/tex]
We have feet as the numerator, so we want feet in the denominator in what we're multiplying this by. In 3 feet = 1 yard, we can multiply this to get
[tex]\frac{60 feet }{1} * \frac{1 yard}{3 feet} \\= \frac{60 yards}{3}[/tex]
= 20 yards

How old will be her brother in five years ?? When Mona was 10, her brother was half her age. If Mona is 57 now, how old will be her brother in 5 years?
Answer:
57
Step-by-step explanation:
When mona was 10, her brother was half her age, so he was 5 years old.
That means that Mona is 5 years older than her brother
If mona is 57, that means that her brother is 52 years
5 years later is 52+7 so her brother will be 57

Strontium-90 has a half-life of about 28 years. Which equation will solve the problem of how many grams of a 40 g sample
will remain after 84 years?
Oy = }(40)
y = {(40)
Oy = 40(1)
y = 40()
84
Answer:a0 = 40 mg
a1 = 20 mg after 28 years
a2 = 10 mg after another 28 years
Step-by-step explanation:Set this up as
10 = 40 (1/2)t/28
and solve for t in years.
10/40 = (1/2)t/28
log(0.25) = (t/28) log(0.5)
t = 28 log(0.25) / log(0.5) years = 56 years
Answer:
40 mg
Step-by-step explanation:
10 = 40 (1/2)t/28 and solve for t in years. 10/40 = (1/2)t/28 log(0.25) = (t/28) log(0.5) t = 28 log(0.25) / log(0.5) years = 56 years

Adapted from Tess-India (Elementary Mathematics)
Explain step by step, how you arrived at your answer to determine the area
and perimeter of the figure in the grid paper.
The perimeter of a shape is the summation of the visible lengths of the figure. The area; however, is the product of the length and the width of the figure
The perimeter of the figure is 58 units and the area of the figure is 130 unit square
Your question is not properly formatted and the diagram required to solve the question is missing. I've included the appropriate diagram.
Having said that, the perimeter is:
Perimeter = sum of all sides
[tex]Perimeter = 7 + 8 + 5 + 8 + 3 + 6 + 3 + 5 + 7 + 6[/tex]
[tex]Perimeter = 58[/tex]
To calculate the area, we use a different approach.
First, we split the figure into 3, we then calculate the area of each sub-figure, and then we add up the calculated areas.
From left to right, we have:
Rectangle 1
[tex]Length = 7\\Width = 6[/tex]
Rectangle 2
[tex]Length = 5\\Width = 6+8 = 14[/tex]
Rectangle 3
[tex]Length = 3\\Width = 6[/tex]
The area of a rectangle is:
[tex]Area = Length * Width[/tex]
So, the area of the figure is:
[tex]Area = 7 * 6 + 5 * 14 + 3 * 6[/tex]
[tex]Area = 130[/tex]

Staff at a fast food restaurant make up the cleaning solution in their spray bottles from a concentrate. In each 300mL bottle they pour 50mL of concentrate and fill the bottle the rest of the way with water. What is the ratio of concentrate to water used?
Answer:
1 : 5
Step-by-step explanation:
So 50mL is for thye concentrate then the rest is water which means the water is 300mL - 50mL = 250mL of water.
Ratio of concrentrate to water = 50mL: 250mL
To write a ratio you first write down the one stated first then the other one.
50mL : 250mL CAN BE SIMPLIFIED. This is done by dividing both parts by the highest common factor which is 50.
It then becomes 1 : 5.

What are the slope and the y-intercept of the linear function that is represented by the graph?
through: (3, - 3); slope = 2/3
Answer:
y=2/3x - 5
Step-by-step explanation:
Since we have the slope and a point, we can make an equation in point intercept form (y=mc+b) by using the point slope form formula (y-y1)=m(x-x1), where (x1,y1) is the point you plug in.
(y-y1)=m(x-x1)
m=2/3
y1=-3
x1=3
y- -3=2/3(x-3)
y+3=2/3(x-3)
Distribute 2/3 with (x-3) by multiplying
y+3=2/3x - 2
Subtract 3 from both sides
y=2/3x - 5
