Answer:
Step-by-step explanation: 4y+8=9 is an equation. 3-2 is an expression. 7y<6 is an inequality!
Answer:
2(3(8))+2(8)=64
Step-by-step explanation:
Here, w represents the width of the rectangle,
∵ length of the rectangle is 3 times the width of the rectangle,
So, length = 3w,
Since, the perimeter of a rectangle, P = 2(length + width)
= 2(w + 3w)
= 2w + 2(3w)
If P = 64 feet,
⇒ 2w +2(3w) = 64
⇒ 2w + 6w = 64
⇒ 8w = 64
⇒ w = 8
Verification :
P = 2(8) + 2((3(8)) = 16 + 48 = 64 feet
Hence, the first step that should be taken to verify that the width of the rectangle is 8 is 2(3(8))+2(8)=64
Note : a solution obtain from an equation is verified by substituting the value in the equation.
Step-by-step explanation:
total working duration = 2 weeks
Working duration in hours = 38× 2= 76 hours
a) per year
24*3115.35 = $74768
b) 3115.35/2
$1557.675
c)
3115.35/76
$40.99
1)12 ÷ 3 = 4.
2) 4×2= 8.
3) 9× 8= 72.
4) 8² = 64
5) 64+ 72 = 136
6) 136 - 7 = 129.
If you just want to simplify the expression you get: 8² + 9(8) - 7
But when you simplify that you get the answer below.
ANSWER: 129
2/3(3) = 6/3 = 2 cups almonds
5/8(2) = 10/8 = 1 1/4 cups raisins
