Will give ! explain how to write an equation when given a description of a mathematical problem or real-world scenario

see below

Step-by-step explanation:

This means to be able to be given a word problem like: Jessica went to the store and spent $2.25 on candy, $2.50 on chips and $2.00 for a soda.  How much did Jessica spend?

Given this you are able to write: $2.25 + $2.50 + $2.00 = $6.75

In most cases, mathematical problems of real world scenarios can be solved using slope form: y=mx+b where y is the total amount, m is number per something (ex $1.50 per candy bar), and b is the fixed amount of something (ex tax).

Step-by-step explanation: (Made up problem) Person went to a candy store with $65. Person bought an ice cream cone for $5.99 and later bought a few bags of chips. The price per chip was $3.40. How many chips did Person buy?

The equation will be set up as 65=3.40x+5.99 (It is good to write out the word problem so that it is easier to identify your options like this: 65=total amount, $3.40 per bag of chip, 5.99 for ice cream).

Subtract 5.99 on both sides: 59.01=3.40x (We are solving for x, the number of chips)

Divide 3.40 on both sides to isolate x: x≅17.35 bags of chips... so Person was ripped off by getting a bag containing less than half of the amount of chips the bag should have.

To check if the answer is correct, plug in 17 to the original equation, 65=3.40(17.35)+5.99 and solve:

65=58.99+5.99

65=64.98 (this is a made-up scenario so the measurements won't be exact).

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )
