Answer:
10
Step-by-step explanation:
Answer:
the length is 8ft
the width is 3ft
Step-by-step explanation:
Step one:
given
perimter= 22ft
let the length be x
width = x-5
Step two
the expression for the perimeter of a rectangle is
P=2L+2W
substituting our data
22= 2(x)+2(x-5)
open brackets
22=2x+2x-10
collect terms and solve for x
22+10=4x
32=4x
divide both sides by 4
x= 32/4
x= 8ft
the length is 8ft
the width = x-5= 8-5= 3ft
Answer:
Step-by-step explanation:
Study the steps used to solve the equation.
Given: StartFraction c Over 2 EndFraction minus 5 equals 7
Step 1: StartFraction c Over 2 EndFraction minus 5 plus 5 equals 7 plus 5
Step 2: StartFraction c Over 2 EndFraction plus 0 equals 12
Step 3: StartFraction c Over 2 EndFraction equals 12
Step 4: 2 (StartFraction c Over 2 EndFraction) equals 12 (2)
Step 5: c equals 24
Answer:
He multiplied the denominators incorrectly
Step-by-step explanation:
we know that
The volume of a rectangular prism is given by the formula
V=LWH
we have
L=3/4 ft
W=5/1 ft
H=1/2
substitute
V=(3/4)(5/1)(1/2)= 3x5x1= 15
₋₋₋₋₋₋₋₋ ₋₋₋₋ ft³
4x1x2= 8
therefore
He multiplied the denominators incorrectly
