Answer: y= -19/2 x+3
Step-by-step explanation:
38x+4y=12
Step 1: Add -38x to both sides.
38x+4y+−38x=12+−38x
4y=−38x+12
Step 2: Divide both sides by 4
Answer:
They complete the hill in 8 hours
Step-by-step explanation:
We will need to solve these equations with a system of equations, so we need to isolate one variable in one of the equations and then replace it with another equation. After this, this means that Beatrice alone would construct the hill in 24 hours and Charlie 40. So, after finding the value A we will need to add A with B and C. This would get us . We will then divide . This will leave with 8h.
A= 7/120h
C=1/40h
B= 1/24h
Step-by-step explanation:
As we know that a unit rate is basically the ratio of different kinds of quantities.
When we have to compare two different type of quantities, we use unit rate.
When price is involved we normally tend to say 'the price of the item per unit amount'.
Here from the given options following are the three unit rates that could be used to describe the price of juice.
- '$1.59 per pint' can be used as unit rate which determines that one pint of juice can can be bought by $1.59.
- '$2.00 per quart' can be used as unit rate which determines that one quart of juice can can be bought by $2.00.
- '$2.99 per gallon' can be used as unit rate which determines that one gallon of juice can can be bought by $2.99.
BUT We can not use '$1.00 per 12 ounces' as a unit price because it is basically NOT the price per 1 ounce.
