The solution is x = -61/8 and y = -1/2.
<u>Step-by-step explanation</u>:
The given equations are -4x + 3y = 29 and 2y + 5 = 4
<u>Step 1</u> : There is no x term in the second equation.
<u>Step 2</u> : Solve for y, 2y = 4 -5
y = -1/2
<u>Step 3</u> : Substitute y = -1/2 in first equation and solve for x.
<u>Step 4</u> : -4x + 3(-1/2) = 29
-4x -(3/2) = 29
-8x -3 = 29
2
-8x = 58 + 3
x = -61/8
Answer:
12.7272
Step-by-step explanation:
subtract 10 on both sides
divide by 11 on both sides 11/11>140/11
Choice (A) has zero slope becsuse her cost doesn't depend on the number of visits.
Answer:
60
Step-by-step explanation:
Given: 60% out of 100
Expressed mathematically:
= (60/100) x 100
= 60
The 90 gallons of water is in the fish tank if the fish tank has 240 quarts of water. Levi adds another 120 quarts to the tank.
<h3>What is unit conversion?</h3>
It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, multiplication by a conversion factor.
We have a fish tank has 240 quarts of water.
Levi adds another, 1201 quarts to the tank.
Total water in the tank = 240 + 120 = 360 quartz
To convert quartz to gallon, divide by 4
Total water in the tank = 360/4 = 90 gallons
Thus, the 90 gallons of water is in the fish tank if the fish tank has 240 quarts of water. Levi adds another 120 quarts to the tank.
