Answer: 875
Step-by-step explanation:
You can set up proportions so it’s like: 1/350=2.5/x and then solve for x
The answer I. C : negative correlation, and casualty
Answer:
- c) Four times x over four equals four over four; Division Property of Equality
===========================
Given equation and steps to solve it:
- 4(x + 1) = 8
- 4x + 4 = 8
- 4x + 4 - 4 = 8 - 4
- 4x = 4
- 4x/4 = 4/4 <u>This is the missing step</u>
- x = 1
All steps given above including the missing one. As we can see, we divided both sides by 4, so the justification for this step is Division Property of Equality.
Hence, the correct choice is C.
Step-by-step explanation:
Hey there!
The given equation is;
-3x+4y = 2
Now, from this equation;



As we know that the slope of line which are parallel to eachother is equal.

Formula is
ₙCₖ = (n!)/( k!*(n-k)! )
so ₇C₃ = (7!) / (3! * (7-3)!)
and 7! = 7 * 6 * 5 * 4 * 3 * 2 * 1
= (7 * 6 * 5 * 4 * 3 * 2 * 1)/(3 * 2 * 1 * 4!)
= (7 * 6 * 5 * 4)/(4!)
= (7 * 6 * 5 * 4)/(4 * 3 * 2 * 1)
= (7 * 6 * 5 )/(6 * 1)
= (7 * 5 )/( 1)
= 35
