-2x+14y=148*3x+5y=256
(-2x+14y)/148=3x+5y=256/148
(-x+y)37/7=3x+5y=64/37
37*7(x+y)/37=(3x+5y)*37=64/37*37
7(x+y)=111x+185y=64
7x-111x=-7y-185y+64
104x=191y+64
x=191y+64/104

Part 2) <span>What is the surface area of this cube?
we know that
surface area of a cube=6*b</span>²
where b is the length side of a cube
in this problem
b=15 mm
so
surface area of a cube=6*15²----> 1350 mm²
the answer Part 2) is 1350 mm²
Part 3) What is the surface area of this cube?
we know that
surface area of a cube=6*b²
where b is the length side of a cube
in this problem
b=11 cm
so
surface area of a cube=6*11²----> 726 cm²
the answer Part 3) is 726 cm²
part 4) <span>What is the surface area of the rectangular prism represented by the net?
surface area=2*16*6+2*16*8+2*6*8----> 544 cm</span>²
the answer Part 4) is 544 cm²
Part 5) <span>What is the surface area of the wood block?
surface area=5*5+4*[5*8]/2----> 25+80----> 105 in</span>²
the answer part 5) is 105 in²
Answer:
j = 44/3
Step-by-step explanation:
j varies jointly as g and v. This can be represented mathematically as:
.............(1)
Where k is a constant of proportionality
j = 2 when g = 4 and v = 3
Substitute these values into equation (1)
2 = k * 4 * 3
2 = 12 k
k = 1/6
when g = 8 and v = 11:
j = (1/6) * 8 * 11
j = 44/3
