Find value of 'k' and solve for unknown variable
Answer:
k = 27/4
y = 283.5
Step-by-step explanation:
Let
y = amount of water used
x = number of dogs washed
y = kx
y = 81 gallons
x = 12 dogs
y = kx
81 = k * 12
81 = 12k
Divide both sides by 12
81/12 = 12k/12
k = 81/12
k = 27/4
k = 6.75
Find x when y = 42 dogs
y = kx
y = 27/4 * 42
y = (27*42) / 4
y = 1,134 / 4
y = 283.5
y = amount of water used = 283.5 gallons
Factor 49p+42.

QUICKK The Johnson family went to a socially distance movie and paid $30 for two adults and two children the modern family went to the same movie and paid 35 for two adults and three children what was the price of an adult ticket
Answer: adults = $10
Step-by-step explanation:
x = adults
y = children
2x + 2y = 30
2x + 3y = 35
Using the elimination method:
2x + 2y = 30
-2x - 3y = -35 (multiplied by -1, to give 2x -2x = 0)
Solve for y...
2y = 30
-3y = -35
Add together...
-y = -5
Multiply by -1 to give positive value for y...
y = $5
Plug into one of the original equation to find x...
2x + 10 = 30
2x = 20
x = $10
Pls help I am stuck and it is due soon number 6
Answer:
1/4
Step-by-step explanation:
First, you add all the marbles together to make the total. 6 + 5 + 4 + 9 = 24.
Then, make 6 the numerator and 24 the denominator. [tex]\frac{6}{24}[/tex]
Next, simplify. [tex]\frac{6}{24}[/tex] = [tex]\frac{3}{12}[/tex] = [tex]\frac{1}{4}[/tex]

what is the supplement to an angle that measures 84°?
1) 84°
2) 76°
3) 6°
4) 96°
Answer:
4) 96°
Step-by-step explanation:
Supplementary angles add up to 180.
So 180-84=96
Answer:
answer: 96
Step-by-step explanation:
A supplementary angle adds up to 180 degrees so 96 is the missing angle because
96 + 84 = 180 Hope that helps!

elisha wants to attend the town carnival. the price of the admission to the carnival is $5.50, and each ride costs an additional 88 cents. if he can spend at most $26.00 at the carnival, which inequality can be used to solve for r the number of rides elisha can go on, and what is the maximum number of rides he can go on?
(1) 5.50 + 0.88r ≤ 26.00; 23 rides
(2) 0.88 + 5.50r ≤ 26.00; 23 rides
(3) 5.50 + 0.88r ≤ 26.00; 24 rides
(4) 0.88 + 5.50r ≤ 26.00; 24 rides
please explain
Answer:
5.50 + 0.88r ≤ 26.00; 24 rides
or 5.50 + 0.88r ≤ 26.00; 23 rides
Step-by-step explanation:
mrk me brainliest plz
i can't explain it i just look at a math problem and auotomatically know the answer
Answer:
(1) 5.50 + 0.88r ≤ 26.00; 23 rides
Step-by-step explanation:
First of all, please understand the equation itself. We are multiplying 0.88 by r, or the number of rides. First, lets determine how many rides Elisha can ride. 0.88 * 23 = 20.24. And 20.24 + 5.50 = 25.74. This is less than 26.00. Now, 0.88 * 24 = 21.12 + 5.50 = 26.7. Though not by much, this is more than 26.00, so, Elisha cannot ride more than 23 rides. That eliminates options (3) and (4). The difference between (1) and (2) is that in (1) we are multiplying 0.88 by r which is correct, however, option (2) is multiplying 5.50 by r which is incorrect. Thus we have our answer. However, please note one important thing. I want you to understand the reason for the "≤" sign as this is very different from <. The sign used here indicates "less than OR equal to" whereas the other is "less than." The sign used indicates that this is the MAX Elisha can spend but he could also spend less. This may seem simple but it is crucial to have a good understanding of this concept as you progress. Any further questions just comment! Hope this helps:) P.S. do not just take the answer! READ, PRACTICE, AND UNDERSTAND.

Gift Wrapping A gift box has the shape of a rectangular prism. How much wrapping paper do you need to cover the box?
Answer: v= 3360
If you’re looking for the volume V=whl =14 • 16 • 15= 3360
answer:
768 in²
step-by-step explanation:
since the box is being wrapped, you'll need to use the tsa (total surface area) formula-
a=2(w*l+h*l+h*w)
= 2·(6·15+14·15+14·6)
= 768

Andrew has a round trampoline with a diameter of 4 yards. What is the circumference of the trampoline?
You would use this formula for the problem...
(C=2πr) The circumference equals 2 multiplied by pi and radius.
In this problem it says diameter, but the diameter is just twice the length of the radius, so just multiply the radius by 2. Plugin your number.
C=2π(2) since 2 is half of 4, that's your radius.
Your answer is roughly C= 12.57.
You're welcome.

Is the following expression a monomial, binomial, or trinomial? 2a^2 - 5a + 7
Answer: Trinomial
Step-by-step explanation: This expression has 3 terms (2a^2, -5a, and 7), so it is a trinomial. An easy way to remember this is that 'tri' = 3, 'bi' = 2, and 'mono' = 1. Hope this helped :)

Find the area explain how you got your answer
Answer:
189.27in^2
Step-by-step explanation:
Area of the rectangle is l*w
15*10= 150
Area of the circle is π r^2
We don't have radius but we have diameter so 10/2 =5
so A= π 5^2
78.53982, but we need half that since its only half a circle.
78.53982/2 = 39.26991
39.26991 + 150 = 189.26991

Write story problem that uses addition and has a solution of 6 (x=6)
Answer:
Let me give you an example of a segment addition problem that uses three points that asks the student to solve for x but has a solution x = 20.
First, I assumed values for each x, y and z and then manipulated their coefficients to get the total at the end of each equation.
20 + 10 +30 = 60
40 + 0 + 40 = 80
40 + 10 = 50
Then exchangeing these numbers into values and we have the following equation.
x + 2y + 3z = 60
2x + 4z = 80
2x + z = 50
If you will solve them manually by substituting their variables into these equations, you can get
x = 20
y = 5
z = 10
