Answer:
60 = n
Step-by-step explanation:
This problem can be rewritten as:
18 is 30% of what?
% means "out of 100" and of means "multiply"
18 = 30/100 ⋅ n
100/30 ⋅ 18 = 100/30 ⋅30/100 ⋅ n
1800/30 = 100/30 ⋅ 30/100 ⋅ n (both the 30/100 and 100/30 are crossed out here)
60 = n
Ryan must do a total of 60 problems
Having done 18 problems already he has 42 remaining.
Answer:
18: x=98 y=38
19: x=20 y=50
Step-by-step explanation:
To figure out figure 18 you would first figure out x and a triangle equals 180 so 180- (36+46) which is 180-82= 98 and then there are vertical angles between the right and left side so x is equal to one of the angles on the right so 98+44= 142 and 180-142= 38
Then to figure out figure 19 you would first find y by adding 39 and 91 to get 130 and 180-130=50 and then 180-91 (for the angle in the bottom right for the left triangle) is 89 so 89+71=160 and 180-160 is 20.
