Both systems can be sloved by susbituding (1,2)
Step-by-step explanation:
(1)- x−4y=−7
Substitute in the x and y values: 1 - 4 (2) = -7
Multiply the numbers : 1 - 8 = -7
Calculate the difference: -7 = -7
(2) - −x+2y=3
Substitute in the x and y values: -1 + 2 (2) = 3
Multiply the numbers : -1 + 4 = 3
Calculate the sum: 3 = 3

Sophia bought 9 red peppers for $5.40.
PLEASE HELP
Find the unit rate. Then use the unit rate to write an equation relating the cost in dollars c to the number of red peppers p.
Answer:
$0.60/each
Step-by-step explanation:
$5.40/9=0.60 Total price *($5.60) divided by 9 (PEPPERS) = $0.60
c= 0.6p
What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
Cost of 9 red peppers = $5.40
Cost of 1 red pepper = 5.40 /9
= 0.6
Now, the equation to represent cost in dollars c to the number of red peppers p,
c= 0.6p

Food bill before tax $45 sales tax 6.8% tip 24%
Answer:
The total bill is $58.86
Step-by-step explanation:
Percentages
Before tax, the food bill is $45. Sales tax is 6.8% and the tip is 24%.
Tax is 6.8*$45/100 = $3.06
Tip is 24*$45/100 = $10.80
Total additional charges are:
$3.06+ $10.80= $13.86
Thus, the total bill for the food is:
$45 + $13.86 = $58.86
The total bill is $58.86

Check all that apply.
For any value of x, g(x) will always be greater than h(x).
For any value of x, h(x) will always be greater than g(x).
g(x) > h(x) for x = -1.
g(x) h(x).
For negative values of x, g(x) > h(x).

What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
Let the measure of the other interior angle = M
The exterior angle is equal to the sum of the interior angles in a given triangle.
An exterior angle of a triangle has a measure of 80°, and one of the remote interior angles has a measure of 20°.
This means,
M + 20 = 80
Solve for M.
M + 20 = 80
Subtract 20 on both sides.
M = 80 - 20
M = 60
Thus,
The measure of the other remote interior angle is 60°.

Answer:
83
Step-by-step explanation:
Answer:
x = 59
y = 83
Step-by-step explanation:
First, you need to solve for y in order to solve for x. Using the Triangle Sum Theorem, you will find that y is 83 degrees.
Now, using the Vertical Angles Theorem, you can figure out the third angle of the triangle in which x is, 83.
Using the Triangle Sum Theorem again, you will find that x is 59.

Daniel is looking at two different credit card offers. Credit Card A will give him an APR of 22.45%. Credit Card B will offer will be 1.25% each month. Which the better deal?
Answer:
Credit card B is a better deal
Step-by-step explanation:
in order to compare both credit cards, we must either convert the APR into a monthly rate or the monthly rate to APR.
convert credit card A's APR to monthly rate:
= 22.45% / 12 ≈ 1.87%, which is higher than 1.25%, so credit card B is better
OR
convert credit card B's monthly rate to APR:
= 1.25% x 12 = 15%, which is lower than 22.45%, so credit card B is better
