There is on equation to solve for x so I think it is wrong
Answer:
72 cm i think
Step-by-step explanation:
19+19+10+10+7+7
divide 36 into 540 36 will divide into the 54 1 time subtract 36 from 54, that gives you 18, bring down the zero from the number 540, now you have 180 to divide by 36, 36 will divide into 180 five times, so your answer is 15
The answer is 15
Answer:
[2] x = -5y - 4
// Plug this in for variable x in equation [1]
[1] 2•(-5y-4) - 5y = 22
[1] - 15y = 30
// Solve equation [1] for the variable y
[1] 15y = - 30
[1] y = - 2
// By now we know this much :
x = -5y-4
y = -2
// Use the y value to solve for x
x = -5(-2)-4 = 6
Solution :
{x,y} = {6,-2}

Answer:
16%
percentage is calculated by 100
A. 2500 × 1/100 = 25%
B. 4100 x 1/100 = 41%
41% - 25%
16%
therefore bridge A is 16% shorter than bridge B
