Which of the following equations is equivalent to x - y = 5?

Masja [62]

Answer:

$6x-6y=30$

Step-by-step explanation:

The complete options are

a) x - 2y = 30

b) 4x - 3y = 30

c) 3x - 4y = 30

d) 6x - 6y = 30

The given equation is

$x-y=5$

Verify option d

we have

$6x-6y=30$

Divide by 6 both sides

$(6x-6y)/6=30/6$

$\frac{6x}{6}-\frac{6y}{6}=\frac{30}{6}$

$x-y=5$

therefore

$x-y=5$ and $6x-6y=30$ are equivalent

A Family travels at a constant rate and drove 420 miles in 7 hours.If they drive at the same speed ,How many miles will they dri

Mazyrski [523]

Answer:

240 miles

Step-by-step explanation:

Step 1

We find the constant rate at which the family travels

Speed(Rate) = Distance/Time

A Family travels at a constant rate and drove 420 miles in 7 hours.

Speed(Rate) = 420 miles/7 hours

= 60 miles per hour

Step 2

If they drive at the same speed ,How many miles will they drive in the next four hours.?

We are to finally calculate the distance for the next 4 hours

Distance = Speed × Time

Speed = 60 miles per hour

Time = 4 hours

Distance = 60 miles per hour × 4 hours

Distance = 240 miles

Therefore, for the next 4 hours the number of miles they would drive is 240 miles
