Given data

1. Expand -2a(5b-3)

open bracket

=-2a*5b + 2a*3

=10ab+3a

2. combined ratio= 2+3= 5

Dayo's share is #120

let us apply the part to all approach

2/5=120/x

cross multiply

120*5= 2x

600=2x

x= N300

Hence the amount is N300

A 3-gallon bottle of fabric softener costs $33.24. What is the price per quart?

asambeis [7]

Answer:

$2.77 per quart.

Step-by-step explanation:

There are four quarts in a gallon.

4 * 3 = 12

There are 12 quarts in 3 gallons.

$\frac{price}{quart} =\frac{33.24}{12}=\frac{33.14/12}{12/12}=\frac{2.77}{1}=\boxed{2.77}$

The price per quart should be $2.77.

Hope this helps.
