Move the x's to the same side
2x + x = 8 +6
then simplify
3x = 14
make x stand on its own
(3x)/3 = 14/3
the 3's on the x side cancel
x = 14/3
Answer:
240 minutes
Step-by-step explanation:
step 1 - 1:56÷14=4
step 2 - 2:4×60=240
The answer is A,
. This is because when plugging in -2 for x, the expression will look like this:
. To make the exponent positive, you have to flip it into a fraction. Then it will be
. Lastly, you simplify the denominator into 81.
First we rewrite the table:
20 30
50 75
80 120
150 ?
We observe that for each 30 number of hops, the distance increases by 45 feet.
We must find the slope of the line:
m = (y2-y1) / (x2-x1)
m = (75-30) / (50-20)
m = 1.5
Then, the line is:
y = 1.5x
We substitute x = 150
y = 1.5 * (150)
y = 225
Answer:
Find the ratio of hops to distance traveled (1: 1.5), then multiply 150 by 1.5.
Divide the number of fast balls by the total number of pitches:
240 / 384 = 0.625
