Answer:
202.5cm^2
Step-by-step explanation:
P=2l+2w
63=2(9)+2w
63=18+2w
63-18=2w
45=2w
divide both sides by 2
22.5=w
check:
P=2(9)+2(22.5)
=18+45
=63
Area=l×w
=22.5×9
=202.5cm²
Answer:
for the third one 2/5 for the fourth one 3/5
Step-by-step explanation:
For the first one, I put 10/25 as a fraction and found the least common multiple, which is 5. I then simplified, and got 2/5.
For the second one, I chose 3/5 because there are 3 friends whose names end in a, and 5 friends whose names do not end in a. My theory was that I took the friends and divided them into 2 groups by most common.
hope this helps if it doesn't I will correct myself :)
Answer:
Ellie will need to have 13 slices.
Step-by-step explanation:
The value of p is 5.
<u>Step-by-step explanation</u>:
<u>step 1</u> : The given expression is -6( p -5 )
<u>step 2</u> : To find any unknown value in an expression, equate it to zero.
<u>step 3</u> : -6( p -5 ) = 0
<u>step 4</u> : Multiply -6 to each term in the bracket.
-6p + 30 = 0
-6p = -30
p = -30/-6
p = 5
