Answer:
55 degrees
Step-by-step explanation:
75+50=125
180-125=55
A triangle's interior angles add up to 180 degrees
I believe the expression would be 3a+3
First we have to find the constraints.
is the total amount of time spent to build the child and the adult bike. Since this time cannot exceed 120, then we get the inequality:
We do the same work for testing time and get the constraint:
Now let check the case c=10 and a=12:
4*10+6*12=112 and this number is less than 120, Ok.
Second contraint:
4*10+4*12=88, the number again is less than 100, OK.
Our answer is than YES, the correct answer is the third one.
Answer: 2 (x + 5) + 2 (3 x minus 2) = 60
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
Length = 3 x minus 2
Width = x + 5.
Since:
Perimeter of a rectangle = 2 length +2 width
Replacing with the values given:
60 = 2 ( x+5)+ 2 (3x minus 2 )
So, the correct option is:
2 (x + 5) + 2 (3 x minus 2) = 60
