0.85 x 60 = 51.

He answered 51 questions correctly.

I know because a percent is out of a hundred, and if he got 60, he got a hundred percent.

4(2-4x)-3x=65 Whats the answer and how did you solve it?
IRINA_888 [86]

Answer:

x= -3

Step-by-step explanation:

Distribute 4(2-4x) which leaves you with 8-16x-3x=65

combine the like terms which leaves you with 8-19x=65

subtract 8 from both sides 8-19x-8=65-8 which leaves you with -19x=57

lastly divide -19 from both sides which leaves you with x= -3

At the science fair, Tanvi uses 8 fluid ounces of vinegar to make her volcano erupt. How many times can she make her volcano eru
SpyIntel [72]

Answer:

4 times

Step-by-step explanation:

1 quart is equivalent to 32 fluid ounces.

If each eruption consumes 8 fluid ounces of vinegar. Assuming that the amount of vinegar required per eruption is constant, the number of times Tanvi can make her volcano erupt is:

n=\frac{32}{8}\\n=4\ times

Tanvi can make her volcano erupt 4 times  with 1 quart of vinegar.

Y=x+5 y = x + 5 Find four points contained in the inverse. Express your values as an integer or simplified fraction.
Karolina [17]

Answer: (0,-5), (5, 0), (10, 5) and (15,10).

Step-by-step explanation:

Given equation: y = x + 5

To find its inverse we will find the value of x .

Subtract 5 from both sides

x=y-5

Switch y to x, we get

y= x-5, which is the inverse function.

At x=0,

y=-5

At x= 5,

y=0

At x= 10 ,

y=5

At x= 15,

y= 10

Hence, the four points contained in the inverse: (0,-5), (5, 0), (10, 5) and (15,10).
