You know 0.4/0.25=x/15 so then do 0.4/0.25=1.6 then take 1.6 times 15 = 24
Answer:
b.
Step-by-step explanation:
cos2θ = 2 cos^2 θ - 1
2cos^2 θ = 1 + cos2θ
cos^2 θ = (1 + cos2θ)/2
Answer:
The relationship ⇒ <u>25x + 40y = 12,250</u>
Step-by-step explanation:
The number of student memberships = x
The number of adult memberships = y
The monthly membership fee for a student = $25
The monthly membership fee for an adult = $40
The total fee = 25x + 40y
Al's Athletic Club receives $12,250 in membership fees for the month of January.
So, the relationship between x and y is:
<u>25x + 40y = 12,250</u>
4.16667 yd.
288 in.
2.5 miles
hope this helps!
Hello from MrBillDoesMath!
Answer: infinite solutions
Discussion: I did a double take on this one but the left hand is
a + 3 + 2a = 3a +3
and the right hand side is
-1 + 3a + 4 = 3a + (4-1) = 3a + 3
The left and right sides of the equation are identical for all "a", i.e. for infinitely many "a" values.
