The meaning of the x-value when y=90 means that Anthony will use 3.1 hours.

<h3>What is an equation?</h3>

An equation is the statement that illustrates that the variables given. In this case, two or more components are taken into consideration to describe the scenario.

The relationship that can be represented by the equation y=57+7.4x,

where

y represents the expected quiz score

x represents hours spent on homework that week.

When y = 90, the value of x will be:

y=57+7.4x

57 + 7.4x = 90

Collect like terms

7.4x = 90 - 57

7.4x = 23

Divide

x = 23/7.4

x = 3.1

He'll use 3.1 hours.

A greedy hamster hoarded 2 piles of sunflower seeds. Yesterday the ratio of the seeds in these piles 3:4; but today the greedy h
Airida [17]

The weight of each pile yesterday will be 6 and 8 pounds.

<h3>What is the unitary method?</h3>

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

It is Given that Yesterday the ratio of seeds in these piles was 3:4.

Let 3x and 4x represent the seeds.

If the 2 pounds of seeds are added in the bigger pile, then

4x + 2

He also ate 1/4 pound from the smaller pile,

3x - 1/4

The quantities of seeds in those piles is in the ratio of 5:16.

So, 4x + 2 = 5x

3x - 1/4 = 16x

Solve;

So, 4x + 2 = 5x

2 = 5x - 4x

x = 2

The weight of each pie will be

3x = 6 pound

4x = 8 pound

Hence, The weight of each pile yesterday would be 6 and 8 pounds.
