Answer: x=2 and y=4/3
Step-by-step explanation:
To solve by substitution method, you want to solve for one variable, and plug it into the other equation.
Let's solve for y in 2x+3y=8.
[subtract both sides by 2x]
[divide both sides by 3]
Now that we have y, we can plug it into the second equation.
[plug in y]
[multiply 3 and y to cancel out the 3]
[distribute -1 to 8-2x]
[combine like terms]
[add both sides by 8]
[divide both sides by 11]
Since we know the value of x, we can substitute it back into any of the 2 equations to find y.
[plug in x=2]
[multiply 2 and 2]
[subtract both sides by 4]
[divide both sides by 3]
Our final answer is x=2 and y=4/3.
<h2>8 tangerines are required</h2>
Step-by-step explanation:
1.4 ounces of juice requires of tangerines. Tangerines have a diameter of .
We need to make a 7 ounce glass of juice. So by simple calculation, we can infer that we need of tangerines.
Volume of each tangerine =
Number of tangerines required =
∴ We require 8 tangerines
Answer:
Firstly
f(x)=3x-2=y then
Interchanging x and y we get
x=3y-2
x+2=3y
y=(x+2)/3
f-1(x)=(x+2)/3
f-1(13)=(13+2)/3
f-1(13)=5
Answer:
155 Degrees
Step-by-step :
(Time x Rate of Temp) + Initial Temp = Final Temperature
Ex. (6 * 15) + 65 = 155 Degrees
