\frac{42}{j}  =  \frac{35}{55}

to solve for j first you need to cross multiply;

j × 35 = 42 × 55

35j = 2,310

j = 2,310 ÷ 35 (did the inverse operation)

j = 66

Hope that helps :D

Each equation represents a linear relationship. Examine each and determine the slope and y- intercept
marysya [2.9K]

Answer:

Slope is -3/7. Y intercept is 250/7.

Step-by-step explanation:

Since they asking for the slope and y intercept, let put it in slope intercept form.

y = mx + b

where m is the slope and b is the y intercept.

The equation given is in standard form so we will convert it to slope intercept.

3x + 7y = 250

7y = 250 - 3x

y =  \frac{250}{7}  -  \frac{3}{7} x

y =  -  \frac{3}{7} x +  \frac{250}{7}

The slope is -3/7

The y intercept is 250/7

Canada has a population that is about 1/10 as large as the United States. If Canada's population is about 32 millon, about how m
bezimeni [28]
Since 32 mil is 1/10 of the US pop, multiply 32 mil by 10 so you get the 10/10 aka the whole US pop. That means it would be 320,000,000. All you do is add a zero to 32 mil since you multiply by 10. 32 mil originally had 6 zeros. After multiplying, you have 7 zeros.
