Answer 1
1) (3,4), 2) (1,9), 3) (4,4)
Answer 2
answer: (3,4)

multiply both sides of the top equation by 2

get rid of the x variable by subtracting add all corresponding numbers and variables (4+(-4), -4+7, -4+16) which leaves you with 3y=12

divide both sides by 3 which cancels out the 3y and leaves you with y=4

input y in your top equation to find x. (-2x+2x4=2)

this leaves you with x=3

I HOPE THAT MADE SENSE!!!

Nate and 2 friends share a pizza equally.He eats half of his share of the pizza.

The total number of persons is 3.

So, each of them is getting [tex]\dfrac{1}{3}[/tex] of a pizza.

It is given that Nate eats half of his share of the pizza. So, the half of his share is:

[tex]\dfrac{1}{2}\times \dfrac{1}{3}=\dfrac{1}{6}[/tex]

Therefore, Nate eats 1/6 of the pizza and the required fraction is 1/6.

Hayden had 2 1/2 gallons of water in his watering can. The seed packet said to use 1/4 of a gallon for peppers and 5/8 of a gallon for tomatoes. Hayden then used some of the water for lettuce. If Hayden had 3/4 gallons of water left over, about how much water did he use for lettuce?

i need it by 7 pm

Answers

Answer:7/4 - 7/8 = 14/8 - 7/8 = 7/8 for lettuce

Step-by-step explanation:1/4 + 5/8 = 2/8 + 5/8 = 7/8

= amount used for pepper and tomatoes

2 1/2 - 3/4 = 5/2-3/4 = 10/4 -3/4 = 7/4

= total amount used

so

7/4 - 7/8 = 14/8 - 7/8 = 7/8 for lettuce
