An isosceles triangle has two sides of equal length. The third side is 5 less than twice the length of one of the other sides. If the perimeter of the triangle is 23 cm, what is the length of the third side?
Explain how you would define a variable for this problem.
Answer:
d = 9/10
Step-by-step explanation:
Hi,
d divided by 5/6 = 3/4
You can't divide fractions, instead, you flip the fraction and multiply. So, in this case, you would flip 5/6 to get 6/5 and multiply it by 3/4 to get d.
d ÷ 5/6 = 3/4
Multiply both sides by 6/5 (remember to flip)
d = 3/4 x 6/5
(when multiplying fractions, you can multiply straight across)
d = 18/20
(simplify - both numbers can be divided by 2)
d = 9/10
Hope this helps :)
The fourth option is correct.
Answer:
38 in
Step-by-step explanation:
P=w+w+h+h=18+18+6+6=26+12=38 in
Answer:
