Answer:
2 : 5
Step-by-step explanation:
In order to obtain the ratio between numbers, we divide by the largest common factor between both.
In this question, the numbers are;
36 : 90
The largest common faction is 18. Dividing both numbers by 18, we have;
36 / 18 : 90 / 18
2 : 5
The ratio is; 2 : 5
Answer:
The answer is -21
Step-by-step explanation:
0.5(5 - 7x) = 8 - (4x + 16)
2.5 - 3.5x = 8 - 4x - 16
3.5x - 2.5 = 4x - 8 + 16
3.5x - 4x = 2.5 - 8 + 16
-0.5x = 10.5
x = 10.5/(-0.5)
x = -21
Thus, The answer is -21

Answer:
Julian has <em>16 dimes</em> and <em>6 quarters</em>
Step-by-step explanation:
Let's suppose Julian has q quarters and d dimes
The total coins are 22, that is
q+d=22
q=22-d [1]
The total amount of money he has is 310 cents which are made of 10d dimes and 25q quarters
10d+25q=310
Simplifying by 5
2d+5q=62
Using the relation [1]
2d+5(22-d)=62
2d+110-5d=62
3d=48 => d=16
q=22-16 = 6
So Julian has 16 dimes and 6 quarters
-7, -2, 0, 5, 6 is the correct answer
