Answer: $810 (B)
Step-by-step explanation: first youd need to find how much they pay for 1 hour. In this case, itd be 135/3 = 45. now multiply by 18 (because 1 hr x 18 = 18 hrs). this would get you to 810.
solve 3(b-5) = 27
solve 2x/3 = 6
solve 2(n + 5) = 15
solve a + a + a + a = 24
solve 4c + 6 = 18
please answer with an explanation
50 points given with explanation
Step-by-step explanation:
♤ 3(b-5) = 27
=> 3b - 15 = 27
=> 3b = 27 + 15 = 42
=> b = 42/3
=> b = 14 (Ans)
♤ 2x/3 = 6
=> 2x = 6 × 3 = 18
=> x = 18/2
=> x = 9 (Ans)
♤ 2(n + 5) = 15
=> 2n + 10 = 15
=> 2n = 15 - 10 = 5
=> n = 5/2
=> n = 2.5 (Ans)
♤ a + a + a + a = 24
=> 4a = 24
=> a = 24/4
=> a = 6 (Ans)
♤ 4c + 6 = 18
=> 4c = 18 - 6 = 12
=> c = 12/4
=> c = 3 (Ans)
Lena's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Lena S4.10 per pound, and type B coffee costs $5.95 per
pound. This month's blend used twice as many pounds of type B coffee as type A, for a total cost of $336.00. How many pounds of type A coffee were used?
Answer: Just bought 21 pounds of coffee A
Step-by-step explanation:
We know that she consumed twice as many pounds of Type B coffee as type A.Then let the total number of cafe feet A=x ; then the number of cafe feet B=2x . We also know that the total number of feet cost $336And the fact that one pound of coffee A costs $ 4.1 ; and one pound of coffee B costs $ 5.95 Then :[tex]\large \boldsymbol {} 2x\cdot 5,95 +x\cdot 4,1 =336 \\\\ 11,9x+4,1x=336 \\\\ 16x=336 \\\\ \boxed{x=21}[/tex]The $5$th power of what number is equal to $3^{15}$?

What is an equation of the line that passes through the point (-8, -1) and is
parallel to the line x – 4y = 4?
Answer:
y = 1/4x + 1
Step-by-step explanation:
x - 4y = 4
x - 4 = 4y
1/4x - 4/4 = y
1/4x -1 = y
Slope: 1/4
Point: (-8,-1)
y-intercept = -1 - (1/4)(-8)=
-1 + 2 = 1

Below are two parallel lines with a third line intersecting them 107
Answer:
x° = 107°
Step-by-step explanation:
Given that m < 107° and m < x° are alternate interior angles that do not have a common vertex on alternate sides of the transversal, then it means that they have the same measure. It also implies that their supplements will have the same measure, 73°.
Therefore, x° = 107°.

Answer:
107
Step-by-step explanation:
they r on opposite sides so they are the same.
An NHL hockey player has 59 goals so far in a season. What are the possible numbers of additional goals, g , the player can score to match or break the NHL record of 92 goals in a season? Write and solve an inequality to solve the situation described above.
The cost (c) to buy gasoline for a car varies directly to the amount of gas (g) in gallons purchased. Helen spent $16.72 on 8 gallons of gas for her car. Nathan is buying the same gasoline, but only has $10.45 to spend. How many gallons of gas can Nathan buy? How do you know?​
Answer:
5 gallons
Step-by-step explanation:
1) How much did Helen spend per gallon?
16.72/8 = $2.09/gallon
2) 2.09g = 10.45
10.45/2.09 = g

It costs $45 for a flower arrangement and $.30 per mile for delivery. If the total cost came to $49.80, how many miles were the flowers delivered?
Set up an equation to solve for the number of miles driven.
Jim rented a truck for one day . There was a base fee of $18.95 and there was an additional charge of 74 cents for each mile driven . Jim had to pay $119.59 when he returned the truck . For how many miles did he drive the truck ??
Answer:
136 miles
Step-by-step explanation:
subtract $119.59 with how much he rented the truck for, which is $18.95 which makes his money at $100.64, then divide by how much each mile costed which was 74 cents
which gives you 136 so 136 miles.

Answer:
[tex]2(x+11y)[/tex]
Step-by-step explanation:
Rearrange:
[tex]10x-7x-x+13y+9y[/tex]
Subtract and Add:
[tex]2x+22y[/tex]
Simplify:
[tex]2(x+11y)[/tex]
Answer:
x + 11y
Step-by-step explanation:
Working in parts starting with x...
10x-7x = 3x
3x - x = 2x
Moving on to y...
13y + 9y = 22y
Put it together
2x + 22y
Simplify by dividing both by a common number ( in this case 2)
x + 11y

wins some money on the lottery. She uses 1/3 of her lottery win to buy a house
and she gives 1/8 of her lottery win to charity. Molly then shares the remainder of her
lottery win equally among her four children. Work out the fraction of Molly's lottery
win that each of her four children receives.
Answer:11/96
Step-by-step explanation:
1-(1/3)=2/3=14/24
(2/3)-(1/8)=(14/24)-(3/24)=11/24
11/24 divided into 4 again is 11/96

Answer:
-31/4
Step-by-step explanation:
[tex]\frac{1}{2} ^{2}[/tex] is actually just (1/2)(1/2) and that equals 1/4
2 - (2/3) you can simplify to (6/3) - (2/3). that equals 4/3
now put it together!
(1/4) - 6(4/3)
(1/4) - (24/3) --------> (which simplifies to 8)
1/4 - 8 ----> (now you have to simplify this to match 1/4 denominator)
(1/4) - (32/4)
-31/4

using the remainder theorem which quotient has a remainder of 20?
Answer:
D
Step-by-step explanation:
When a polynomial f(x) is divided by (x - a) then remainder is f(a)
A
divided by (x + 4 ), then a = - 4
[tex](-4)^{4}[/tex] - 8(- 4)² + 16 = 256 - 128 + 16 = 144 ≠ 20
B
divided by (x - 2), then a = 2
3(2)³ + 7(2)² + 5(2) + 2
= 3(8) + 7(4) + 10 + 2
= 24 + 28 + 12 = = 64 ≠ 20
C
divided by (x + 5) , then a = - 5
(- 5)³ + 5(- 5)² - 4(- 5) + 6
= - 125 + 125 + 20 + 6 = 26 ≠ 20
D
divided by (x - 2), then a = 2
3[tex](2)^{4}[/tex] - 5(2)³ + 5(2) + 2
= 3(16) - 5(8) + 10 + 2
= 48 - 40 + 12 = 20 ← Remainder of 20

A shipment of sugar fills
4/9 containers. If each container holds 2 2/5
tons of sugar, what is the amount of sugar in the entire shipment?
Write your answer as a mixed number in simplest form.
Answer:
For this problem, multiply these fractions.
First, make each one an improper fraction: 2 4/5 is the same as 14/5 and 2 3/7 is the same as 17/7.
Now, 14/5 times 17/7 yields 238/35 which reduces to 34/5. This may be expressed also as the mixed fraction 6 4/5.
So, the shipment contains 6 4/5 tons of sugar. (This is also equal to 13,600 pounds of sugar.)

A company that teaches self-improvement seminars is holding one of its seminars in
Hampton. The company pays a flat fee of $69 to rent a facility in which to hold each session.
Additionally, for every attendee who registers, the company must spend $15 to purchase
books and supplies. Each attendee will pay $18 for the seminar. Once a certain number of
attendee register, the company will be breaking even. How many attendees will that take?
What will be the company's total expenses and revenues?
Step-by-step explanation:
I take it that the $69 flat fee is for one event.
and we are talking about one event overall.
"breaking even" means that the sum of all expenses and revenues is 0.
so, with x being the number of attendees,
0 = 18x - 15x - 69
69 = 3x
x = 23
that means, with 23 attendees they will break even, and with every attendee more they will gain.
in the case of 23 attendees the company will have expenses of 69 + 23×15 = $414.
and the revenues are 23×18 = $414
