Answer:
4n-7
Step-by-step explanation:
First, you know that Sam's equation is 4n, since it is 4 times Declan's value n. Next, you take Sam's equation and subtract 7 from that value, since Amaya has 7 fewer cards than Sam. The final equation will be 4n-7.
Answer:
Okay I get it now, N is equal to 4-7.

PLS I NEED HELP!!! If Mary can paint 1/4 of a wall in 20 minutes, how long will it take her to paint a room with 4 walls?
Answer:
80 minutes
Step-by-step explanation:
One wall takes 20 minutes, so 20×4=80 minutes.
Answer: 320 minutes
Step-by-step explanation:
1/4 of a wall takes 20 minutes, therefore one wall takes 80 minutes. Multiply that by 4 for 4 walls, and that becomes 320 minutes.
Marcus earned $230 for 40 hours of work. Phillip earned $192 for 32 hours of work. Are these pay rates proportional? Explain.
Answer:
No.
Step-by-step explanation:
Find ROC for Marcus and Phillip
Marcus
230/40 = $5.75 per hour
Phillip
192/32 = $6 per hour
$6 > $5.75
Answer:
These pay rates are not proportional
Step-by-step explanation:
Dividing 230 by 40 gave 5.75, so Marcus earns $5.75 per hour he works
However, dividing 192 by 32 gives 6, which shows that Phillip earns $6 per hour and $0.25 more than Marcus

Find the percent of change. Round your answer to the nearest tenth of a percent, if
necessary.
a. Original price: $185
New price: $160
b. Original number of students: 56
New number of students: 77
Answer: a. 14% decrease or 86% of the whole
B. 137.5% increase
Step-by-step explanation:
A. Divide new price by old price and you get .86, change that to a percent by multiplying by 100. That equals 86%, the percent of change would be the difference of 100% to 86%, which is 14%
B. Use above explanation but don’t find the difference. 77/56= 1.375, 1.375*100=137.5
The percentage of decrement for case a will be around 13.52% and the increment in case b will be 37.5%.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is equivalent to the quantity of that value between 1 and 100, and it is highly helpful for forecasting. For instance, if you say 678, we must also know the whole number, but if you say 80%, it is obvious.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
Case a)
Given that
Original price: $185
New price: $160
% decrement = (change/original)100
% decrement = (185 - 160 )/185 × 100 ⇒ 13.52%
Case b)
The original number of students: 56
New number of students: 77
% increment = change/original × 100
% increment = (77 - 56)/56 × 100 ⇒ 37.5%
Hence the percentage change for case a) will be 13.52% and that of case b) will be 37.5%.

Hey everyone, I suck at math so here's a question to the people who don't:
12x+(-4x+1)3
Answer:
24x+3
Step-by-step explanation:
Not sure if you're supposed to simpilfy or solve for x but I simplifyied it!
First you want to start with (-4x+1) which becomes 12x, so recreate the expression to 12x+12x+3. Then combine likes terms, 12x+12x=24x. Then you can't do anything with the 3 so it becomes 24x+3!

A gym charges its members a one-time $20.00 sign-up fee, and $25.00 per month. The function rule f(x) = 25x + 20 describes the relationship between the number of months x, and the total cost of membership f(x). If a gym member paid $170.00, for how many months did the gym member pay?
A. 4 months
B. 5 months
C. 6 months
D. 7 months
Answer:
C 6 months
Step-by-step explanation:
since u pay 20$ to sign up u can subtract that from 170=150
and then to find how many months the member payed divide by 25 since its how much u pay each month to get 6 months
The number of months that gym member pay will be 6 months. Then the correct option is C.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
A gym charges its members a one-time $20.00 sign-up fee and $25.00 per month. The function rule f(x) = 25x + 20, where 'x' is the number of months.
If a gym member paid $170.00. Then the number of months that gym member pay will be given as,
170 = 25x + 20
170 - 20 = 25x
25x = 150
x = 6 months
The number of months that gym member pay will be 6 months. Then the correct option is C.
