Answer:
The cost for a child is $7 and the cost for an adult is $50
Step-by-step explanation:
Let 'x' represent children
Let 'y' represent adults
The equations used to come to this answer are:
Therefore; x = 7
If the shop takes 15 percent off of $15 I would take 15 x .85 to get this 15 percent off giving Mindy $12.75 to spend. With a $12 pizza having 5 percent tax you take 12 x 1.05 too get a total of $12.06 as her total. This means in an even trade Mindy would lose 15 cents to the Pizza Shop

Answer:
(c) 144 m²
Step-by-step explanation:
The surface area can be calculated from ...
SA = 2(LW +H(L+W))
SA = 2((6 m)(6 m) +(3 m)(6 m +6 m))
= 2(36 m² +(3 m)(12 m)) = 2(36 m² +36 m²) = 2(72 m²)
SA = 144 m²

The units of area are square meters (m²). The units of volume are cubic meters (m³).
Answer: 52
Step-by-step explanation:
cos=7/11.4 -> cos-1(cosB) = cos-1(7/11.4)
m<B = cos-1(7/11.4) = 52
Answer:
y – 1= Three-halves(x + 3)
Step-by-step explanation:
line goes through (-2, -4) and (2, 2)
goes through (-3, 1)
slope = (-4 - 2) / (-2 -2) = -6/-4 = 3/2
1 = (3/2)*-3 + b
1 = -9/2 + b
b = 1 + 9/2 = 11/2 = 5.5
y = (3/2)*x + 11/2
(y - 1) = (3/2)(x + 3)
