Answer: length = 75 cm
Step-by-step explanation:
61 x 2 = 122
272-122= 150
150 divided by 2 = 75
check: 75+61= 136
136 x 2 = 272
hope this helps!
Answer:
a) 10/3
Step-by-step explanation:
2x - 6 + 5x = 1/3 x - 9 + 2y
7x - 6 = 1/3 x - 9 + 2y
or
2y = 7x - 1/3 x - 6 + 9
2y = 21/3 x - 1/3 x + 3
2y = 20/3 x + 3
y = 20/6 x + 3/2
y = 10/3 x + 3/2
Y = mx + b where m = slope
In this case slope m = 10/3
Equation 1) 3x + 3y = 12
Equation 2) x - 5y = 10
First step : 3(x - 5y = 10)
Well, we have to simplify this equation first. *Remember, this is the second equation.
Equation 1) 3x + 3y = 12
Equation 2) 3x - 14y = 30
Well, because both equation 1 & 2 have positive 3x in their equations, we must subtract the equations from one another in order to find the y value.
So, your answer is : C) Subtract the equations.
