Well first you would multiply -3 and -4 which is 12 (because two negatives multiplied equals a positive.) then after that multiply by -9 which equals -108 so your final answer is -108

Can someone help me please what is m

Ipatiy [6.2K]

Answer:

m = 20

Step-by-step explanation:

We have two fractions and are asked to find m.

When we have a question like this, cross multiplying is our key, to find m, we need to first find the value of the denominator of the other fraction and the numerator of the same fraction m is in.

Therefore :

$\frac{8}{m} = \frac{6}{15}$

$\frac{8*15}{m*6}$

What is 8 * 15?

120.

Now we need to find what times 6 equals 120 to get m.

Divide 120 by 6

Therefore, m is equal to 20

A farm had 480 acres more wheat than corn. After the farmers collected 80% of the wheat and 25% of the corn, the area of the whe

Sergio [31]

The area covered by corn is x
The area covered by wheat is (x+480)
After 80% of wheat was collected, the new area was:
20/10(x+480)
=1/5(x+480)
After 25% of the corn was collected, the new area was:
75/100x
=3/4x
New area equation will be:
(3/4)x=1/5(x+480)+300
(3/4x)=(1/5)x+96+300
solving for x we get:
11/20x=396
x=720
thus the original area of corn was 720 acres
Original area of wheat was 720+480=1200 acres

The floor of a rectangular deck has an area of 600 square feet. The floor is 20 feet wide. How long is the floor?

Monica [59]

600/20= 30

30*20=600 obviously, so since it is 20 feet wide, it must be 30 feet long to complete an area of 600 square feet. Hope this helps.
