Let assume
X for ice cream cones
Y for sundaes
X+Y=172
X=172-Y……..*
1.10X+2.35Y=294.20
Substitute * in the above equation
1.10(172-Y)+2.35Y=294.20
189.2-1.10Y+2.35Y=294.20
1.25Y=294.20-189.2
1.25Y=105 divide both sides by 1.25
Y=84
The substitute Y value in * equation
X=172-84
X=88
Therefore
88 ice cream cones and 84 sundaes were sold!!
Answer:
8(7 + 4) = 88
Step-by-step explanation:
56:
1 x 56
2 x 28
4 x 14
7 x 8
32:
1 x 32
2 x 16
4 x 8
Y+2=3(x-4)
y+2=3x-12
-2 -2
y=3x-14
slope-intercept form: y+2=3(x-4)
4 + 2 [ 10(6 * 2 - 6) - 40 ]
4 + 2 [ 10(12 - 6) - 40 ]
4 + 2 [ 10(6) - 40 ]
4 + 2 [ 60 - 40 ]
4 + 2 [ 20 ]
4 + 40
44 <===
