Hey there! I'm happy to help!
We have two values for y. Since y=y, this means that −2x + 4 and − 1/3x − 1 are equal as well, so we can put them in an equation and solve for x.
−2x + 4 = − 1/3x − 1
We subtract 4 from both sides.
-2x=-1/3x-5
We add 1/3 x to both sides.
-5/3x=-5
We divide both sides by -1 2/3.
x=3
Now, we plug this into one of the original equations to find y.
y=-2(3)+4
y=-6+4
y=-2
Therefore, the solution is (3,-2) or x=3 and y=-2.
I hope that this helps! Have a wonderful day! :D
The equation you would use is t+25=45 because he volunteered at the hospital for 45 minutes in total. To find T you would do 45-25 which equals 20 and 20 minutes is the amount of time he answered phone calls
The volume of a Cone =

Since for the ice cream cone has h = 4 inches; r = 0.75; π = 3.14
Then Volume of the Cone = 2.355 in³
∴ This ice cream cone can hold ≈
2.36 in³ of ice cream without overflowing
Answer:
0.25s + 6.2
Step-by-step explanation:
Discount on sale expression : 1/4(s + 24.80)
Retail price of shoe = s
Retail price of hats = 24.80
From expression, we can conclude that there is a ; 1/4 = 0.25 = (0.25 * 100%) = 25% discount on each item ;
Hence, discount expression could be written as :
0.25s + 0.25(24.80)
0.25s + 6.2
Set it up.
Make the equations equal to 180° because they are on a straight line. And a straight line adds up to 180°
