kumpel [21]

Answer:

6 miles per gallon

Step-by-step explanation:

Given : An experimental vehicle was able to travel 3/8 miles on 1/16 gallon of water.

To Find: At this rate, what was the mileage in miles per gallon of water for this vehicle?

Solution:

Since An experimental vehicle was able to travel 3/8 miles on 1/16 gallon of water.

So, the mileage in miles per gallon of water for this vehicle:

$\frac{\frac{3}{8}}{\frac{1}{16}}$

${\frac{3}{8}*16$

$3*2$

$6$

Thus the mileage of water for this vehicle is 6 miles per gallon

Can somebody number the problem and work it out for me thanks and btw it’s solving system by graphics

adoni [48]

Answer:

Solutions are (3,1) and (4,2)

Step-by-step explanation:

Graph is shown in the attached sheet

Given are two systems of equations and we have to solve them using graph

For graphing let us first prepare table for x and y.

1) $y=\frac{-2x}{3} +3:\\y=2x-5$

I line II line

x 0 4.5 3 x 0 2.5 3

y 3 0 1 y -5 0 1

The two lines intersect at (3,1)

Hence solution is (3,1)

--------------------------------------------

2) $y=\frac{x}{2} \\-6x+3y=-18$

I line II line

x 0 2 4 x 0 6 4

y 0 1 2 y 3 0 2

The two lines intersect at (4,2)

Hence solution is (4,2)

Find the first three terms of the sequence below. 3n^2+5n−2

Otrada [13]

Answer:

-2, 6, 20 ,...

Step-by-step explanation:

3n² +5n -2

if n=0 , then 3*0² +5*0 -2= -2

if n=1, then 3*1² +5*1 -2 = 3+5-2 = 6

if nu 2, then 3*2² +5*2 -2 = 12 +10 -2 = 20
