Hello!
The expression that is one of the steps in determining how many pieces can be cut is B. 3/4 • 10/1
12.5 is 25% of x
percent means parts out of 100
25%=25/100=1/4
12.5=1/4 of a number
mulitply both sides by 4
50=number
the number is 50
Answer:
(-2, 2)
Step-by-step explanation:
this is the point where y= -2x+1 meets y=2x+3
13 feet! 12 inches = 1 foot, and think of below ground as negative feet, so it’d be the difference between -1 and 12, which is 13!
Answer:
x = ± 10
Step-by-step explanation:
To solve the equation let y = 0 , that is
0 = 100 - x²( add x² to both sides )
x² = 100 (I take the square root of both sides )
x = ± 
= ± 10
Then solution is x = - 10, x = 10
