Answer:
35
Step-by-step explanation:
1. Write the equation
y = 1.245x - 3.684
2. Set y = 40, since that is the cost of the songs he purchased.
40 = 1.254x - 3.684
3. Add 3.684 to both sides
43.684 = 1.254x
4. Divide by 1.254
x = 35.0875502
Trapezoid and paralellogram are both quadrilaterals
the heiarchy is
quadrilaterals are 4 sided figures
quadrilaterals is split up into
A. no pairs of paralell sides
- kite
B. 1 pair of paralell sides
- trapezoid/trapezium
C. 2 pairs of parell sides (paralellograms)
-rectangles
-rhombus
-square
so you can see that they are both quadrilaterals (quad=4, lateral=sides, quadrilateral=4 sided figure)
R/ r+ 15 = 3/8
Cross multiply: top of one side multiplied by bottom of other side:
R x 8 = 3 x r+ 15
Simplify:
8r = 3r + 45
Subtract 3r from both sides:
5r = 45
Divide both sides by 5:
R = 9
