Add the x's
SO 3x=18
divided by 3
So x=3
In the equation, x represents the number of balloons. We say that 25 cents per balloon becomes 0.25x.
Jimmy also purchased a chocolate cake. This is the PLUS sign in the equation.
The total for everything purchased is $35.
Balloons x at 25 cents each = 0.25x plus a chocolate cake for $10 together equals $35.
I think 115 min because its just 23 x 5 so you just multiply that to get the asnwer
Answer:
2 gallons
Step-by-step explanation:
25% of 4 gallons is 1 gallons, which means that 75% of the hand sanitizer is not alcohol, and is 3 gallons. since that is the amount of not alcohol, and we want it to be 50% solution, it has to be 3 gallons of alcohol in total, and 3-1=2.
No spaces? like t h i s? or like thiiiss??? is this bugging you ????
anyway
use elimination
multiply secn equation by -1
-3x-2y=-6
add to other equation
-3x-2y=-6
<u>4x+2y=10 +</u>
1x+0y=4
x=4
sub back to solve for y
3x+2y=6
3(4)+2y=6
12+2y=6
minus 12 both sides
2y=-6
divide 2
y=-3
(4,-3)
