X=cost for 1 soft taco
x=cost for 1 doubledecker
dory is
11.25=3x+3y
nemo buys
10=4x+2y
we have
11.25=3x+3y and
10=4x+2y
divide second equation by 2
5=2x+y
multiply by -3
-15=-6x-3y
add to first equatin
-15=-6x-3y
11.25=3x+3y+
-3.75=-3x+0y
-3.75=-3x
divide both sides by -3
1.25=x
subsitute
5=2x+y
5=2(1.25)+y
5=2.5+y
minus 2.5
2.5=y
double dekesr cost $2.50
soft tacos cost $1.25
45.60$ i belive
explained: i used the desmos calculator lol
Number of students in Math136 = 480
We are given that the number of students in Math136 is 20% more than the number of students in Math123. Let the number of students in Math123 be x. So we can set up the equation as:
Number of students in Math136 = 20% more than number of students in Math123
Number of students in Math136 = 20% more than x
480 = 20% more than x
480 = 20% of x + x
480 = 0.20x + x
480 = 1.20(x)
x = 480/1.20 = 400
This means, there are 400 students in Math123.
