Answer:

5 divided by (-3)

Step-by-step explanation:

5 3/4 is equals to:

\frac{5*4}{4} + \frac{3}{4} = \frac{23}{4}.

-3 3/8 is equals to:

\frac{-3*8}{8} - \frac{3}{8} = -\frac{27}{8}.

The division of two fractions is the multiplication of the first one divided by the inverse of the second one. So:

\frac{\frac{23}{4}}{-\frac{27}{8}} = -\frac{23}{4}*\frac{8}{27} = \frac{46}{27} = 1.70

As for the answers, we have that:

6 divided by (-3) is -2.

6 divided by (-4) is -1.5.

5 divided by (-3) is -1.67.

5 divided by (-4) is -1.25.

So the best estimation for -1.70 is:

5 divided by (-3)

olga_2 [115]

Answer:

Step-by-step explanation:

2ax−3<4x+5a

Step 1: Add -5a to both sides.

2ax−3+−5a<5a+4x+−5a

2ax−5a−3<4x

Step 2: Add 3 to both sides.

2ax−5a−3+3<4x+3

2ax−5a<4x+3

15/10 to a mixed number
tensa zangetsu [6.8K]
First, we have to find how many times 10 goes into 15.

We can divide 15 by 10, and we will see that 10 goes into 15 1 whole time, with 5/10 left over.

Now, we can simplify!

In order to simplify, we have to find the GCF (greatest common factor) of 5 and 10. Let's list out the factors (the numbers that can be divided into 5 and 10)

1*5

1*10
2*5

The largest factor, as we can see, is 5! Let's dicide 5/10 by 5.

5/5=1
10/5=2

So, 5/10 simplifies to 1/2, and, if we bring down the whole number we found before, 15/10 is equal to 1 and 1/2! :)

We can check this answer by multiplying the whole number, 1, by the denominator, (the bottom number of a fraction) 2, and adding the numerator, (the top number of a fraction), 1.

1*2=2
2+1=3

Keep the denominator as 2.

The improper fraction is 3/2, which is equivalent to 15/10 (multiply 3/2 by 5 to see)!

So, our answer is 1 1/2.

I hope I helped! :)

C: At least: three vans, or two small trucks, or one large truck

Step-by-step explanation:

V=Lhw R=$/ft³

Vv=10.5(6)(6)

Vv=378 ft³

Rv=94.5/378

Rv= 25¢ per ft³

Vs=12(8)6.75

Vs=648 ft³

Rs=162/648

Rs=25¢ per ft³

------

Vl=20(8.75)8.5

Vl=1487.5 ft³

1487.5=648n

2.295=n
