3x - 2y = 5
-2x + 2y = -2
--------------------add
x = 3
3x - 2y = 5
3(3) - 2y = 5
9 - 2y = 5
-2y = 5 - 9
-2y = -4
y = -4/-2
y = 2
solution is (3,2)
ur system of equations is : 3x - 2y = 5 : -2x + 2y = -2
80%
Ummm bro the explanation is simple he keeps 8/10 and he saves 2/10 sooo
8/10 x 10 = 80/100 spends 80%
2/10 x 10 = 20/100 saves 20%
Easy peasy...
Answer:
3 foil, 6 latex
Step-by-step explanation:
First, you can put all of these words words into equations. We know there are 162 ballons (18 players)(9 bouquets). So we can put it in the equation
x + y = 162
Since each foil balloon costs $1.92 and each Latex balloon costs $.19 and they all cost $124.20. We can put it in an equation:
.19x + 1.92y = 124.20
You then get the systems of equations:
x + y = 162
.19x + 1.92y = 124.20
solving for the equation, you get x = 54 and y = 108. BUT, you have to be careful. The problem said "How many of each type of balloon did each <em>bouquet</em> include?" So we need to divide both by 18 for the player because each player recieved on bouquet.
.4=2/5
80=2
X =5
2x=400
X=200
Answer:
Width is 10 1/2 inches and the length = 21 inches.
Step-by-step explanation:
Let the width be x then the length us 2x inches.
Perimeter = 2x + 2(2x) = 63
6x = 63
x = 10 1/2 inches.
