Answer:
3√10
Step-by-step explanation:
Sadie= 82
Buddy= 54
Divide by 2, 136/2=68, then rest 14 to one half, 68-14=54, next add the other half 14, 68+14=82.
There you have it, i hope it helps you
Answer:
x= -13
y= -28
Step-by-step explanation:
To find the two numbers, write a system of equations with x as one number and y as another:
x-y=15
5x=2y-9
Use substitution to substitute one equation into another. Then solve for the variable.
x=15+y into 5x=2y-9
becomes
5(15+y) = 2y-9
75+5y = 2y- 9
75+3y= -9
3y = -84
y= -28
To find x, substitute y= -28 into one equation.
x - (-28) = 15
x+28 =15
x = 15-28
x=-13
