Answer:Justin plans to spend $20 on sports cards. Regular cards cost $3.50 per pack and foil cards cost $4.50 per pack
number of packs of regular cards =r and the number of packs of foll cards = f
Cost of Regular card = 3.50
Cost of 'r' packs of regular card = 3.50r
Cost of Foil card = 4.50
Cost of 'f' packs of Foil card = 4.50f
Justin plans to spend $20 on sports cards so the sum of cost of regular and Foil cards should be less than or equal to 20
The inequality becomes
3.50r + 4.50f <= 20

Answer: 40 pages in total
Step-by-step explanation:
Ms. Vega has read 20% of the book and this translates to 8 pages of the book.
20% = 8 pages
Assume the total number of pages is x:
20% * x = 8
0.2x = 8
x = 8 / 0.2
x = 40 pages in total

After 5 years, the sum of the ages of Reema and Neha will be 30. If Reema is 4 years
younger than Neha today, then find the sum of the present ages of Reema and Neha.
years
Answer:
Sum of their present ages = 20 years
Step-by-step explanation:
Present age :
Neha's age = x years
Reemas' age = x - 4
After 5 years:
Neha's age = (x +5) years
Reemas' age = (x - 4 + 5 ) = x + 1
Sum of the ages of Reema and Neha will be 30
Therefore,
x + 5 + x + 1 = 30
x + x + 5 + 1 = 30
2x + 6 = 30
2x = 30 - 6
2x = 24
x = 24/2
x = 12
Neha's age = 12 years
Reema's age = 12 - 4 = 8 years
Sum of their present ages = 12 + 8 = 20 years
If ben completes 1/4 of his book report in 5/6 of an hour how much of the book report does ben complete per hour?
Answer: Ben completes 3/10 of his book report per hour
Step-by-step explanation:
Ben completes 1/4 of his book report in 5/6 of an hour
5/6 of an hour = 5/ 6 x 60 = 50 minutes
Therefore in 1 hour, which is = 60 minutes he completes
(1/4 x 60 minutes)/ 50 minutes
= 15/ 50
= 3/10 of his book report.

Step-by-step explanation:
f(x)= -x + 4
Therefore f(-1)= -(-1)+4= 1+4= 5
h(x)= (3/2)x - 1
Therefore h(2)= (3/2)(2) -1= 3-1= 2
f(-1) - h(2)= 5 - 2= 3

You deposit $750 in a bank
account that will earn a simple
interest of 3.5% per year.
How much will your investment
be worth after 12 years?
Answer:
$1,065
Step-by-step explanation:
Simple interest equation: A=P(1+rt)
P (principal amount) = 750, r (rate) = 3.5%, t (time) = 12 years
A=750(1+(3.5)(12))
A=1065
The amount of an investment to be worth after 12 years should be considered as the $1,065
Calculation of an investment:Since
The deposited amount is $750
The rate of interest is 3.5% per year.
And, the time period is 12
So,
A=750(1+(3.5)(12))
A=1065
Hence, The amount of an investment to be worth after 12 years should be considered as the $1,065

You have $3.10 in dimes and quarters.You have 3 more dimes than quarters. write an equation that relates the number of coins and have any equation for the value of the coins.how many of each kind of coin do you have?
Answer:
y=Q+3D
Step-by-step explanation:
the total amount is y=, than A would be quarters. and you add 3 because there's always 3 more dimes than quarters than add D for dimes.
The system of equations is 0.10x + 0.25y = 3.10 and x = y + 3. The number of dimes and quarters will be 11 and 8, respectively.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
You have $3.10 in dimes and quarters. You have 3 more dimes than quarters.
Let 'x' be the number of dimes and 'y' be the number of quarters. Then the equation is given as,
0.10x + 0.25y = 3.10 ...1
x = y + 3 ...2
From equations 1 and 2, then we have
0.10(y + 3) + 0.25y = 3.10
0.10y + 0.30 + 0.25y = 3.10
0.35y = 2.8
y = 8
Then the value of 'x' is given as,
x = 8 + 3
x = 11
The system of equations is 0.10x + 0.25y = 3.10 and x = y + 3. The number of dimes and quarters will be 11 and 8, respectively.

R(-2,8) S(10,6) midpoint
Answer:
M = (4,7)
Step-by-step explanation:
If points are (x₁,y₁) and (x₂,y₂), then the midpoints are given by :
[tex]M=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})[/tex]
We have,
x₁ = -2, y₁ = 8, x₂ = 10 and y₂ = 6
So,
[tex]M=(\dfrac{-2+10}{2},\dfrac{8+6}{2})\\\\=(\dfrac{8}{2},\dfrac{14}{2})\\\\=(4,7)[/tex]
So, the midpoints of the given points are (4,7).

Mike installed the window shown. How many square feet is the window? Use 3.14 for pi. Round to the nearest tenth.
Answer: 3.9ft²
Step-by-step explanation:
Find the area of the rectangle first:
= Length * Width
= 2 * 1.5
= 3 ft²
Find the area of the semi-circle by finding the area of a circle and dividing it by 2:
= πr²
= 3.14 * 1.5/2 * 1.5/2
= 1.76625ft²
Divide by 2:
= 1.76625/ 2
= 0.88 ft²
Add the area of the rectangle to the semi-circle:
= 3 + 0.88
= 3.9ft²
The volume of a cube related to the area of a face by the formula V =A^3/2. What is the volume of a cube whose face has an area of 25mm^2.
Answer:
Volume = 125 mm^3
Step-by-step explanation:
Here, we want to get the volume of the cube
What we have to do here is to substitute the value of the area
We have this as
:
V = 25^(3/2)
V = (√25)^3
V = 5 * 5 * 5 = 125 mm^3
