Answer:
(x, y) = (2 2/9, -1 4/9)
Step-by-step explanation:
Equate the values of y and solve for x.
1/4x -2 = -2x +3
(2 1/4)x = 5 . . . . . . . . add 2+2x to both sides
x = 20/9 = 2 2/9 . . . multiply by 4/9
y = -2(2 2/9) +3 = -4 4/9 +3 . . . . substitute for x in the second equation
y = -1 4/9
The solution is x = 2 2/9, y = -1 4/9.
Answer:
19 bars =<u> 76 more ores.</u> 22 bars = <u>88 total ores.</u>
Step-by-step explanation:
y = 4x
(4 times a number. Ex: x could be 98740757 or 2, it doesn't matter.)
1 b = 4 o
3 b = 12 o
22 - 3 = 19 b
19 b = 76 o (more)
22 b = 88 o (total)

Answer/Step-by-step explanation:
Part A: Net A is the correct net. If we decide to fold the net, we'd get the shape of the prism. Folding back net B won't give us the shape of the prism because of the position and arrangement of the right triangular bases.
Part B:
AB = 3in
BC = 5 in
CD = 9.4 in
Part C: surface area of the prism can be calculated by calculating the area of each part of the net, and summing them together as follows,
Area of the 2 triangular bases = 2(½*base*height of triangle) = 2(½*4*3) = 2*2*3 = 12 in²
Area of the three rectangles =

Surface area of prism = 12 + 112.8 = 124.8 in²
The final solutions are C1=7, C2=14
