Answer:

I think it is not proportional because the line is supposed to go thro the middle of each dot, and some of the dots don't have a line thro the middle only on the side or not even on the dot.

Hope this helps!

Two automobiles start together from the same place and travel along the same route. The first averages 40 miles

natita [175]

Answer:

A. (55 x 5) - (40 x 5)

Step-by-step explanation:

You are solving how much miles (further along) would the second car be after 5 hours.

The first car averages 40 miles per hour. 5 hours later, it will have averaged about 200 miles in 5 hours (40 x 5 = 200).

The second car averages 55 miles per hour. 5 hours later, it will have averaged about 275 miles in 5 hours (55 x 5 = 275)

Subtract: 275 - 200 = 75

The second car would have averaged 75 more miles than the first car.

Solve.<br> 4 x + 6 < − 6<br><br> Thankyou In advance :>

andrew-mc [135]

Answer:

x < -3

Step-by-step explanation:

Step 1: Subtract 6 from both sides.

$4x + 6 - 6 < -6 - 6$
$4x < -12$

Step 2: Divide both sides by 4.

$\frac{4x}{4} < \frac{-12}{4}$
$x < -3$

Therefore, the answer is x < -3.

The ratio of boys to girls in a school is 5:4. if there are 500 girls , how many boys are there in the school?

lana [24]

Answer:

The number of boys in the school is;

$625$

Explanation:

Given that the ratio of boys to girls in a school is 5:4;

$5\colon4$

And there are 500 girls in the school.

The number of boys in the school will be;

$\begin{gathered} \frac{B}{G}=\frac{5}{4} \\ G=500 \\ B=\frac{5\times G}{4}=\frac{5\times500}{4} \\ B=625 \end{gathered}$

Therefore, the number of boys in the school is;

$625$
