Answer:

Esmeralda added the numerators; Esmeralda added the denominators; Esmeralda did not use the reciprocal of the divisor

Step-by-step explanation:

-5 1/4 divided by 3/2 = -7/2

The same goes for the second fraction.

For the -21/4 and the 3/2 with the parenthesis, they added the numerators and denominators when they should've multiplied.

And they did not use the reciprocal of the divisor because -21/4 divided by 3/2 would mean that you would have to multiply -21/4 by 2/3 not 3/2.

Mon wants to make 5 lbs of the sugar syrup. How much water and how much sugar does he need…

nata0808 [166]

Whatever% of anything, is just (whatever/100) * anything.

the syrup is going to be 5lbs total, that includes the sugar in it as well as the water mix.

keeping in mind that the syrup will be a 1.5% syrup, namely 1.5% of it will be sugar, the rest just water then, how much is 1.5% of 5?

well, is just(1.5/100) * 5 or 0.075, namely lbs.

so, 0.075 lbs will be sugar and the rest water, the rest will be 5 - 0.075, or 4.925 lbs.

Suppose f varies directly as g, and f varies inversely as h. Find g when f = 10 and h = –12, if g = 56 when h = –2 and f = –7. R

kow [346]

Answer:

-480

Step-by-step explanation:

If f varies directly as g, and inversely as h, then we can write the variation equation:

$f=\frac{kg}{h}$ , where k is the constant of variation.
