The answer is b. 200
<span>If y varies inversely as x, then: y = c/x
We know:
y = 40
x = 5
y = c/x
c = y * x
c = 40 * 5
c = 200</span>
Answer:
20, 45
Step-by-step explanation:
A triangle has 180 degrees interior angle measure. One angle measure 115 so that means the other two angles must add up to 65.
The remaning angles form a ratio of 4:9. This means we must split 65 into a ratio of. 4:9
A ratio partition parts of something. We can add the ratio intergers to find it full length.
4+9=13.
Divide 65/13=5.
Multiply 5x4 and 5x9 serpately.
We get 20 and 45
The answer is : X=-7/3-2/3y
