Answer 2

To solve (-2/5)n=-30, you will need to solve for n. To do this, you will need to divide both sides by (-2/5), which will give you n=-75.

Answer 3

yes, @Hlares is right, -75 equals n

Answer 4

can u help with 3 more

Answer 5

Also remember that, when you divide by a fraction, you can also multiply both sides by the fraction, but with the numerator and denominator switched around, like so:
(-2/5)n=30
(-2/5)(-5/2)n=30(-5/2)
1*n=-75
n=-75

Answer 6

Carla's plant was 10 2/3 inches tall. Yolanda's was 8 3/4 inches tall.

How much taller was Carla's plant than Yolanda's?

Answer 7

i think 1 11/12

Answer 8

in.

Answer 9

To find the height, you will want to subtract the height of Yolanda's plant from the height of Carla's plant. To do this by hand, you will first want to turn the heights of both plants into fractions that have the same denominator.

First, convert both into fractions:
The height of Carla's plant will be the product of 10 and (2/3), thus: 20/3.
The height of Yolanda's plant will be the product of 8 and (3/4), thus: 6.

Second, you want to have the same common denominator for both fractions. As we have a denominator of 3 for Carla's plant and Yolanda's is a whole number, let's make 6 have a denominator of 3 as well. To do this, we will multiply the numerator and denominator by 3. Thus:
6*(3/3)=18/3

Now you can subtract the height of Yolanda's plant from the height of Carla's plant to find the difference in their heights:
20/3-18/3=2/3.
Thus, there is a 2/3 inch difference in height.
