Remember to do the same thing to both sides

use distributive prpoerty which is
a(b+c)=ab+ac so
pemdas
multiplication
8(x+1/4)=8x+8/4=8x+2
3(6x-9)=18x-27

now we have7x+8x+2=18x-27-8
add like terms
15x+2=18x-35
subtract 15x from both sides
2=3x-35
add 35 to both sides
37=3x
divide both sides by 3
37/3=x
12 and 1/3=x

A brick of cheese is 3/4 inch thick. A deli cuts the brick of cheese into slices that are 1/10 inch thick. How many slices are c
marysya [2.9K]
The way I would do this is convert everything into a common denominator. Therefore, the cheese block is 15/20 inch thick and each slice is 2/20 inch thick. Then 15/2 would be 7 with a remainder of 1 so you can cut 7 slices and have 1/20 inch of cheese left over.

Len [333]

Answer:

y > (x - 50) * 210

Step-by-step explanation:

Given :

Number of dead trees = 50

Number of oranges produced by each of the remaining trees > 210

Let total number of trees = x ; total number of oranges produced = y

Hence, number of oranges produced, y

y > number of remaining trees * number of oranges produced per tree

y > (x - 50) * 210
