Answer: 4.6 is the answer to 1.38 divided by 0.3=4.6
16 is 40 because you just need to add 16 to 14 and to 10 which is equal 40
Basiclaly solve for y
8x+4y=16
minus 8x both sides
4y=-8x+16
divide by 4 both sides
y=-2x+4
Multiply both sides by 4
subtract 24r from both sides
simplify r - 24r to -23r
divide both sides by -23
two negatives make a positive
simplify 14/5/23 to 14/5 x 23
simplify 5 x 23 to 115
switch sides
Answer: r = 14/115.
