Answer:
14
Step-by-step explanation:
In an equation our aim is to find the value of what we are looking for as well as keeping the equation balanced. For example if we took away 16 only from one side then the equation would change so it's an important rule to bare in mind when solving equations, that you need to keep both sides of the equation the same.
4 ( d + 4 ) = 72
→ Expand the brackets
4d + 16 = 72
→ Minus 16 from both sides to isolate 4d
4d = 56
→ Divide both sides by 4 to isolate d
d = 14
Answer:
0.53
Step-by-step explanation:
Basically just go to your calculator and put in 8 divded by 15
The answer is 74. The parenthesis is another way of telling you to multiply.
Answer:
<em>The width of the lid is 15 cm</em>
Step-by-step explanation:
<u>The Perimeter of a Rectangle</u>
Given a rectangle of width W and height H, the perimeter is calculated as:
P = 2(W + L)
Jon used 56 cm of ribbon to go around the edge of a rectangular lid. This means the perimeter is:
2(W + L) = 56
Dividing by 2:
W + L = 28
Since the lid was L=13 cm long, the width is:
W = 28 - 13 = 15
The width of the lid is 15 cm
