Answer:
x=1, y=-1. (1, -1).
Step-by-step explanation:
-x+2y=-3
-8x-3y=-5
----------------
-8(-x+2y)=-8(-3)
-8x-3y=-5
------------------------
8x-16y=24
-8x-3y=-5
-----------------
-19y=19
y=19/-19
y=-1
-x+2(-1)=-3
-x-2=-3
-x=-3+2
-x=-1
x=1
(1, -1)
Answer:
$32.80
Step-by-step explanation:
Find out how much Nancy spent on 4 violins and 2 song books.
1 violin = 87.82
4 violins = 87.82 x 4 = 351.28
1 song book = 7.96
2 song books = 7.96 x 2 = 15.92
351.28 + 15.92 = 367.20
4 x 100 dollar bills = 400 dollars
Normally after paying for an item, if you pay much more money than the actual price of the item, you'll get some money back from the cashier. That's called a change.
400 - 367.20 = 32.80
Answer:
c- linear units
Step-by-step explanation:
edg :)
4y + 3 ≤ y + 6
4y + 3 - 3 ≤ y + 6 - 3
4y ≤ y + 3
4y - y ≤ y - y + 3
3y ≤ 3
3y/3 ≤ 3/3
y ≤ 1
So any value of y less than or equal to 1 (so 1 is included in the solution set) satisfies the inequality. C is the correct answer.
24x^2 + 10x = 2x(12x + 5)
