Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.

The inequality is 1.85x - 42.55 > 100. 42.55 is the amount already raised, 1.85x is number of laps times the money raised by them.

In Juan's coin bank there are nickels (n),

Answer:

The answer is 8 quarters, 16 nickles, and 32 dimes

Step-by-step explanation:

First, the equation would be (2/4d) x 5 +d x 10 +1/4d x 25= 600 (Don't put 6.00, that's dollars. We put 6 dollars into cents to make it easier.)
Then we slowly start to solve: 10/4d + 10d + 25/4d = 600
10d+40d+25d/4 = 600 (Put all of that over 4, not first 25d)
75d= 600 x 4
d=600 x 4/75 (same here put everything over 75)
d=32
So then n= 2 x 32/4 = 16
Then n would be equal to : 1/4d= 1/4 x 32 = 8
So your answer would be 8 quarters, 16 nickles, and 32 dimes.

Hope this helped :)

Please help Explanation will be appreciated thanks,

Answer: A; 6.3%

Step-by-step explanation:

Problem 1

For the first problem, we first want to find y so that we can plug it into the expression.

We can use elimination method for the system of equations to solve.

3x+3y=21

3x-y=5

We subtract both equations to eliminate x.

4y=16 [divide both sides by 4]

y=4

Now that we know y, we can plug it into the expression.

$\frac{4}{2} -3$ [divide]

$2-3$ [subtract]

$-1$

We know that the answer is A.

Problem 2

For the second problem, we need to know how to calculate percent error. The formula for precent error is $\frac{|measured-exact|}{exact} *100%$ . We know that the exact value is 80 because the buyer was supposed to given 80. 75 is the measured value because that was what the buyer was given.
