5.2x-y=4.1 1.5x+y=6.7<br> how to solve this problem
MrRa [10]

Answer: x=1.6

y=4.2

Step-by-step explanation:

5.2x - y = 4.1

1.5x + y = 6.7

we will add both equations and you see that the y is getting cancelled

6.7x=10.8

x=10.8/6.7= 1.6

now in any equation we will replace x with 1.6

5.2(1.6)-y=4.1

8.3-y=4.1

  -y= 4.1-8.3

-y=-4.2  multiply by -1

y=4.2

Roopesh has $24 dollars to spend on a birthday gift. The store where he is shopping has a sale offering $5 off the regular price
Natasha2012 [34]

Answer:

r ≤ 29, r-5

The sale price can be compared with the regular price, r-5 ≤ 24

Step-by-step explanation:

Amount to spend = $24

Regular price = r

Sale = $5

Sale Price = r-5

The regular price will be $5, at the max, more than the amount Roopesh has to spend.

The sale price will be $24 or less than that for Roopesh to afford.

Inequality for regular price:

r-5 ≤ 24

r ≤ 29

So, the product Roopesh can afford is $29 or less than that.

What is the unknown? r ≤ 29

Following expression can represent the sale price:

Sale price = r-5  

The sale price can be compared with the regular price with the following:

Inequality representing the situation: r-5 ≤ 24
