To solve the expression 7x + y we can substitute x with 2 and y with 6.
= 7(2) + 6
= 14 + 6
= 20
Best of Luck!
The sum of complementary angles is 90 degrees, thus
3x + 6 + 3x + 18 = 90
=> 6x + 24 = 90
=> 6x = 90 - 24 = 66
=> x = 66 / 6 = 11
=> m<A = 3(11) + 6 = 33 + 6 = 39 degrees.
4/10 is equal to 2/5 because if you reduce 4/10 you get 2/5 which shows that they are equal.
Answer:
first get a common denominator by multiplying 7 and 4 to get 28
28 is our common denominator here.
Step-by-step explanation:
We want to add the fractions 2/7 and 1/4
(2/7) * (4/4) and (1/4) * (7/7)
(2/7) * (4/4) + (1/4) * (7/7) = 8/28 + 7/28 = 15/28
18
the calculated percentage of 75 anf 24 is 18
