Answer:
14 dimes and 17 quarters
Step-by-step explanation:
d and q are the number of dimes and quarters, respectively.
"31 coins, all of which are dimes and quarters."
d+q = 31
d = 31-q
"the value of the coins is $5.65"
0.10d + 0.25q = 5.65
substitution
0.10(31-q) + 0.25q = 5.65
3.10-0.10q + 0.25q = 5.65
0.15q = 2.55
q = 17
d = 31-q = 14
14 dimes and 17 quarters
Find the solution to the system of equations given below:
x=-4
-5x-4y=16
PLS HELP
Answer:
Step-by-step explanation:
Since x=-4 plug in the -4 into the equation to find y,
-5(-4)-4y=16
20-4y=16 -20 -20 __________
-4y=-4
-4y/-4=-4/-4
___________
y=1
So now you found both x and y so plug in both now to check if both are correct.
-5(-4)-4(1)=16
20-4=16
16=16
So both y and x are correct.

Janet's car insurance payment decreases by $30 each year. Which expressions represent the total change in her payment, in dollars, after 4 years?
Answer:
The change after five years is equal to -$100
Step-by-step explanation:
If the insurance payment is equal to P = N dollars, where P is a real number, we know that after one year, the payment decreaces by $20, so the new payment is:
P = N - $20
Then, after 5 years, the $20 dollars are discounted five times, so the payment will be:
P = N -5*$20 = N - $100
Then the total change after 5 years is equal to those $100 that are being subtracted in the last equation.

Day Pictures Uploaded
Monday 2
Tuesday 2
Wednesday 4
Thursday 1
Friday 8
Answer:
25
Step-by-step explanation:
The way I did this was I added all the numbers together (number through Monday-Friday) and got 17. Then I started off with 20, and multiplied 20 by 0.68 to get 13.6, now I’m trying to get up to 17 so I kept going up by 1 to finally try 25 x 0.68 = 17. Hopefully this makes sense!

Jen has 3 bags of pears. Each bag has 5 pears. If Jen gives the same number of pears to 4 friends, how many pairs will each friend get?
Answer:
3 pears each
Step-by-step explanation:
3 bags of pears
5 pears in each
1=5
2=5
3=5
thats 15 pears
15/4=3.75 (so its just 3)
The number of pears each friend get will be 3.75 pears for each friend.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
It is also known as the product. If the object n is given to m times then we just simply multiply them.
Jen has 3 bags of pears. Each bag has 5 pears. Then the total number of the pears will be given by the multiplication of the numbers 3 and 5.
Total pears = 3 x 5
Total pears = 15 pears
If Jen gives the same number of pears to 4 friends.
Then the number of pears each friend gets will be
⇒ 15 / 4
⇒ 3.75 pears for each friend
Thus, the number of pears each friend get will be 3.75 pears for each friend.

Moussa's family took a road trip to the Grand Canyon. Moussa fell asleep after they
had travelled 434 miles. If the total length of the trip was 700 miles, what percentage
of the total trip had they travelled when Moussa fell asleep?
Answer:
38%
Step-by-step explanation:
So first you need to find what 434/700 is because that is when she fell asleep. Divide each side by 2 to get 217/350. Use division to find the decimal. Once you are done with that, you get 0.62. You then subtract 0.62 from 1 because that is the amount of when she fell asleep. 1-0.62=0.38. 0.38 is also 38% so Moussa fell asleep for 38% of the trip.
