Answer: x = 2y
Step-by-step explanation:
Let's solve for x.
2(3x+4y)=4x+12y
Step 1: Add -4x to both sides.
6x+8y+−4x=4x+12y+−4x
2x+8y=12y
Step 2: Add -8y to both sides.
2x+8y+−8y=12y+−8y
2x=4y
Step 3: Divide both sides by 2.
<u>2x
</u>
2
=
<u>4y
</u>
2
x=2y
Answer:
x=2y

Answer:
6 packages
Step-by-step explanation:
27 guests x 2 hotdogs = 54 hotdogs
54 hotdogs/packages of 10 = 5.4
round up because 5 packages wouldn't be enough -- so Mrs. Smith needs 6 packages :)
<h2>
Horizontal distance when projectile strikes water surface is 170 .02 feet</h2>
Step-by-step explanation:
The height is given by
We need to find when it strikes the water surface,
At water surface h = 0 feet
Substituting
Solving this quadratic equation to get x.
-32x² + 2500x + 500000 = 0
32x² - 2500x - 500000 = 0
x = 170 .02 feet or x = -91.90 feet
Negative x is not possible
Horizontal distance when projectile strikes water surface = 170 .02 feet
She is wrong because -2 1/3 is smaller than -1.4. The bigger the negative number is, the smaller it is.
