Answer:
1.6
Step-by-step explanation:
Lets count how many points are x and y away from each other since we dont have a graph.
X and Y points:
35-15=20
56-24=32
Use the formula:
32/20 = 1.6
Answer:
a) 70
Step-by-step explanation:
because it is a C, so it is the median score
Add the common factors which is x plus 2x plus 4x which is 7x so now you have the bx term rewritten to 7x+8
Answer:
x < 3
Step-by-step explanation:
−4x − 8 > −20
Add 8 to both sides.
-4x > -12
Divide both sides by -4. Remember that when you multiply or divide both sides of an inequality by a negative number, the direction of the inequality sign changes.
-4x/(-4) < -12/(-4)
x < 3
The key concept you must have to remember is that, the rate is kept constant, as what is specified in the problem. Our basis for the rate is the first situation.
Rate = 20 facts/ 1 min.
Let's equate this to the second situation using x as the time unknown.
20/1 = 35/x
Solving for x,
<em>x = 1.75 minutes</em>
