Need help with these 2 questions
MArishka [77]

Answer: 1. x= -12           2. x= 12

Step-by-step explanation:

1. 5(+3)=−45

5x+15−15=−45−15

5x= -60

5x/5 = -60/5

x = -60/5

x= -12

2. 1x/2−4=2

x/2 -4=22−4+4=2+4

/2=6

2⋅2=2⋅6

x=2⋅6

x= 12

Given the system of inequalities:
Margaret [11]
Answer:
First inequality: y > \frac{4}{5} x - \frac{1}{5}
Second inequality: y < 3 + x

Explanation:
The inequality in slope-intercept form has the following general formula:
y < mx + c or y > mx + c (according to the given sign)
where m is the slope and c is the y-intercept

This means that to get any inequality in slope-intercept form, we will have to isolate the y on one side of the inequality.

First given inequality:
4x - 5y < 1
4x - 5y + 5y < 1 + 5y
1 + 5y > 4x
1 + 5y - 1 > 4x - 1
5y > 4x - 1
y > \frac{4}{5} x -  \frac{1}{5}
comparing this to the general form, we would find that:
slope (m) = 4/5
y-intercept (c) = 1/5

Second given inequality:
y - x < 3
y - x + x < 3 + x
y < 3 + x
comparing this to the general form, we would find that:
slope (m) = 1
y-intercept (c) = 3

Hope this helps :)

There are two pizzas. Conor ate 1⁄4 of a pizza, Brandon 2⁄8, Tyler 3⁄4, and Audrey4⁄8. Who ate the most of the two pizzas
Kobotan [32]
Tyler ate the most. if you put them all in the same fractions Conor ate 1/4, Brandon also ate 1/4, Tyler ate 3/4 and Audrey ate 2/4. if you want to go by percent then Conor and Brandon ate 25% each, Audrey ate 50% and Tyler ate 75% which means there is still 25% or 1/4 of a pizza left
