Set up a ratio of known to unknown:

Let X = the amount of gas needed for 500 miles:

220/12 = 500/x

Cross multiply:

220x = 6000

Divide both sides by 220:

X = 6000 / 220

x = 27.27 gallons (round answer as needed).

Answer:

(2x+3) y (3x+5)

Step-by-step explanation:

For this exercise we have that the volume is

V = 6x ^ 3 + 31X ^ 2 + 53x + 30

H = X + 2

The formula for the Volume its

V = H * L * W

for find L and W (width and length) we divide V / H = L * W

So,

$\frac{V}{H} =\frac{6X^{3}+31X^{2}+53X+30 }{X+2}=(2x + 3) * (3x + 5)\\$

this division is in the attachment

so, L * W = (2x + 3) * (3x + 5)

Can somebody please help me

guajiro [1.7K]

Here is your answer

B. (12,30)

REASON:

Given,

$y= 2x+6$ .......(i)

$3x-y= 6$ .......(ii)

Putting the value of y from eq.i in eq.ii we get

$3x-(2x+6)=6$

$3x-2x-6=6$

$=6+6$

$x=12$

Putting x=12 in eq.i we get

$y= 2x+6$

$y= 2×12+6$

$y= 24+6$

$y= 30$

So,

$\bold{x=12 and y= 30}$

Hence answer is (12,30) in which x=12 and y=30

You are comparing to wireless services. Verizon changes $35 a month and $5 per gigabyte of data.

ikadub [295]

A) Gigabytes = x
B) 35+5x = 25+10x
10 = 5x
2 = x
C) After 2 gigabytes, the wireless services will cost the same ($45)
