Carlos is a member of a gym. He pays a monthly fee plus a per- visit fee. The equation y = 3x + 10 represents the monthly amount Carlos pays for x visits. if Carlos pays $85 in the last month how many times did he visit the gym?

25 times

Step-by-step explanation:

To find how many times he visited, plug in 85 as y and solve for x:

y = 3x + 10

85 = 3x + 10

75 = 3x

25 = x

So, Carlos visited the gym 25 times

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

c
