Answer:
$7.50
Step-by-step explanation:
1 battery costs 10/8=5/4 dollars
(5/4)*6=15/2
15/2=7.50
Answer:
$7.50
Step-by-step explanation:
Set up a proportion and cross multiply to find your answer.
8 batteries/$10 = 6 batteries/$x
x = (6)(10)/8
x = 60/8
x = $7.50

x = -3
Step 2: Substitute and Evaluate
5 - (-3) < 8
5 + 3 < 8
8 < 8 ? No
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
When you know what a missing value is you should always plug it in first...
[tex]5-(-3)<8[/tex]
Now we should solve it...
[tex]5-(-3)<8\\5+3<8\\8<8[/tex]
So is this a solution of the inequality?....No because it's false 8 can't be less then itself.
1. Henry is using a total of 40 ft. of lumber to make a bookcase. The left and right sides of the bookcase are each 8 ft. high. The top, bottom, and two shelves are all the same length, labeled .
Part A: Construct an equation to model the situation. (5 points)
Part B: Solve the equation. Show all your steps.
(5 points)
Part C: Use the solution to answer the question in a complete sentence. (5 points)
Answer:
Part A:
40 = 16 + 4·s
Part B:
The length of the top and bottom and the two shelves are each = 6 ft.
Part C:
The width of the bookshelf is 6 feet
Step-by-step explanation:
The given parameters are;
The length of the lumber Henry is using to make the book case = 40 ft.
The height of the left and right side of the book case = 8 ft. each
The length of the top and bottom and the two shelves are each = s
Therefore, we have;
Part A:
The equation is given as follows;
40 = 8 × 2 + 4·s = 16 + 4·s
40 = 16 + 4·s
Part B:
The solution of the equation is given as follows;
40 = 16 + 4·s
4·s= 40 - 16 = 24
s = 24/4 = 6 ft.
s = 6 ft.
The length of the top and bottom and the two shelves are each = 6 ft.
Part C:
The width of the bookshelf is 6 feet
Tenley is making a square frame for her painting. She is using 4 pieces of wood that are each 2.25 feet long.
How much wood will Tenley use to make the frame?
Tenley will use ____________ feet of wood.
Answer:
Tenley will use _9_ feet of wood.
Step-by-step explanation:
The key here is to multiply 4 by 2.25. If just adding 2.25 4 times is easier, go for that. Either way the correct answer will be 9 feet.

Answer:
8. x=18 9. x=33 10. x=65 11. x=19 12. x=59
Step-by-step explanation:
8. The angles are essentially vertical so they have to be equal to each other.
42=2x+6 subtract 6 from both sides 36=2x x=18
9. These angles are supplementary and equal 180 when added together.
98+(3x-17)=180 subtract 98 and add 17 to both sides 3x=99 x=33
10. Angles are essentially vertical so they are equal to each other.
2x+2=3x-63 add 63 to both sides subtract 2x from both sides 65=1x
11. Angles are supplementary so they equal 180 when added together.
112+(4x-8)=180 subtract 112 and add 8 to both sides 4x=76 x=19
12. Angles are vertical so they are equal to each other.
(3x-33)=(2x+26) add 33 to both sides and subtract 2x 59=1x

80 premium memberships must the center sell in order to earn $7260 in membership sales.
What is division?Division is the process of splitting a number or an amount into equal parts.
here, we have,
The premium membership is $90,
and the regular membership is $60.
now,
No. of premium memberships must the center sell in order to earn $7260 in membership sales = $7260÷$90
=7260/90
≈80
hence, 80 premium memberships must the center sell in order to earn $7260 in membership sales.

470470 milliliters each.
How many milliliters of blood did the volunteers donate?
Answer:
470(32 - n)
Step-by-step explanation:
Here are the given:
> 32 volunteers
> n volunteers who didn't donate
> 470 mL each
So your expression is: 470(32 - n).
Why?
Subtract the 32 volunteers who want to donate blood from the volunteers who were not able to donate then multiply it by 470.

passes through (8,-6) perpendicular to 2x+y=-4
Answer: y = 0.5x - 10
Step-by-step explanation:
2x + y = -4
y = -2x - 4
perpendicular, so slope = 1/2
y + 6 = (1/2)(x - 8)
y = (1/2)x - 10
Danice is reselling concert tickets and wants to markup the price at `\frac{1}{6}` of the original price, $231.00. What is the markup price for the concert ticket. Show all your steps.
Given:
Original price = $231.00
Markup price is [tex]\dfrac{1}{6}[/tex] of the original price.
To find:
The markup price for the concert ticket.
Solution:
It is given that, markup price is [tex]\dfrac{1}{6}[/tex] of the original price. So,
[tex]\text{Markup price}=\dfrac{1}{6}\times \text{Original price}[/tex]
[tex]\text{Markup price}=\dfrac{1}{6}\times 231[/tex]
[tex]\text{Markup price}=\dfrac{231}{6}[/tex]
[tex]\text{Markup price}=38.5[/tex]
Therefore, the markup price for the concert ticket is $38.5.

4.6
5. 8
Step-by-step explanation:
Answer:
f(0) = 0
f(1) = 2
f(2) = 4
f(3) = 6
f(4) = 8
Step-by-step explanation:
f(x) = 2x
for each of the values, substitute x for that value.
f(0) = 2*0
f(0) = 0
f(1) = 2 * 1
f(1) = 2
f(2) = 2* 2
f(2) = 4
f(3) = 2 * 3
f(3) = 6
f(4) = 2 * 4
f(4) = 8
Help Needed!! Find The Measure Of Angle A In The Triangle
Answer:
A=40°
Step-by-step explanation:
All angles in a triangle add up to 180°, so we take 60 away from 180 because we know that angle.
180-60=120
Next, we add up the number of x,
10x+20x=30x
Third, we need to find out what x is, so we divide 120 by 30, which gives us 4.
x=4
to find out what 10x is (A), we multiply 4 by 10
4×10=40
A=40

What is the value of X? ( if you are confused please look at the picture provived below)
Answer:
X = 14 I used a calculator an showed work
Step-by-step explanation:
Answer:
x = 14
Step-by-step explanation:
It is given that ∠AOB is a straight line. The definition of a line states that it is 180°, so any line equals to a measure of 180°.
Step 1: Set up equation
m∠AOC + m∠COD + m∠DOB = 180°
(5x) + (3x + 30) + (2x + 10) = 180°
Step 2: Solve for x
Combine like terms: 10x + 40 = 180 Subtract 40 on both sides: 10x = 140Divide 10 on both sides: x = 14Step 3: Check
Plug in x to verify it's a solution.
Substitute: 10(14) + 40 = 180Evaluate: 140 + 40 = 180Evaluate: 180 = 180Please look at the picture! Thank you I
