You bike 9.8 miles in 1.4 hours at a steady rate.What equation represents the proportional relationship between the x hours you

AlexFokin [52]

Answer:

The equation is $\frac{x}{y}= 8$

Step-by-step explanation:

Let the time for which i bike is = x hours

Let the distance traveled in x hours = y miles

Ratio of distance and time will be = x : y

I travel 11.2 miles in 1.4 hours then the ratio of time and the distance traveled will be 1.4 : 11.2 Or 14 : 112

then the ratio of distance and time will be same in both the cases

So equation will be

$\frac{x}{y} =\frac{14}{112}\\\\\frac{x}{y} =8$

Hence, equation representing the proportional relationship will be $\frac{x}{y}= 8$

A building brick weighs 2.7 kilograms. work out the weight of 840 bricks. give the answer in tonnes

Charra [1.4K]

Answer:

2.268 tons

Step-by-step explanation:

Multiply 840 to 2.7 to figure out the weight of 840 bricks.

840 x 2.7 = 2268 kilograms

Convert 2268 kilograms into tons which will be 2.268 tons.

How did I convert? Divide 2268 by 1000 because 1 ton = 1000 kilograms.
