I have included a picture. In the picture you will find the work and final answer.
Answer:
(1) x=
−1
/2
y+
5
/2
(2)
x=
−1
/2
y−2
Step-by-step explanation:
<u>(1)</u> 2x+y=5
Step 1: Add -y to both sides.
2x+y+−y=5+−y
2x=−y+5
Step 2: Divide both sides by 2.
2x
/2
=
(−y+5)/2
x=
−1
/2
y+
5
/2
<u>(2) </u>Step 1: Flip the equation.
−2x−4=y
Step 2: Add 4 to both sides.
−2x−4+4=y+4
−2x=y+4
Step 3: Divide both sides by -2.
−2x
/−2
=
(y+4)
/−2
x=
−1
/2
y−2
Answer:
the answer is y=8.5x
Step-by-step explanation:
because x would equal the hours and y would equal the money.
so you divide y by x, so in this case it would be 127.50/15 and that equals 8.5
so the multiplier or constant of proportionality, if thats what you guys call it, is 8.5.
To solve this, we have to find the volume of a cylinder and a rectangle:
Cylinder: We know that the equation for the volume is πr^2h, so the volume for this cylinder would be 3.14*12.25*2
The volume is 76.93.
Now we solve for the rectangle:
6*9*2 = 108
The volume is 108.
<u>The rectangular cake pan has the larger volume.</u>
