Answer:

She moved 3 to the left and 5 down.

She could have calculated each point seperately.

A(1,-1) then subtract 2 and subtract 6 from the x and then the y-coordanate, which gets you to A'(-1,-7). Then, do this with every other coordanate and you will get your answer. Hope this helped!

Clayton has saved $5.65 in dimes and quarters. He has 10 more quarters than dimes. How many of each denomination of coins does h

Ksju [112]

Answer: Dimes: 9

Quarters :19

Step-by-step explanation:

Hi, to answer this question we have to write a system of equations using the information given:

He has 10 more quarters than dimes

Q = D +10

Clayton has saved $5.65 in dimes and quarters

0.25 Q + 0.10 D = 5.65

Where:

Q= number of quarters

D= number of dimes

Replacing the value of Q for (D+10) in the second equation:

0.25 (D +10) + 0.10 D =5.65

0.25D + 2.5 +0.10D =5.65

0.25D + 0.10 D =5.65-2.5

0.35 D = 3.15

D = 3.15/0.35

D=9

Replacing the value of D by 13 in the first equation:

Q= D +10

Q =9 +10 =19

Mr. Quick bought a new computer system. The regular price was $1580, but he got 40% off. What is the discount

denpristay [2]

Answer: The discounted price is $948. The value of the discount itself is $632.

Step-by-step explanation:

<h3>To calculate discounts, you multiply the percentage of the discount as a decimal with the price of the product.

In this particular case:

0.40 [percentage of discount] x $1580 [original cost] = $632 (the amount of the discount) </h3><h3>$1580 - $632 = $698 [new price after discount is applied]</h3>

The ratio between the number of children (c) on a field trip and number of teachers (t) on the trips is 14/3. There are 70 child

Mrrafil [7]

For this case we have a relationship of the form:
$c / t = 14/3
$
There are 70 children on the field trip
Therefore, we must replace the value of c = 70 in the equation.
We have then:
$70 / t = 14/3
$
Clearing t, we have:
$t = (3/14) * (70)

t = 15$
Answer:
there are 15 teachers on the trip
