Cross multiplication will help find the value of x

9*2=18
3*z=3z
Now we have :
3z=18
Divide both sides by 3 to isolate z
Final answer: z=6
Answer:
9.6 miles per hour
Step-by-step explanation:
First find the unit rate.
25/4= 0.16 miles per minute
Then multiply by 60 ( which we know theres 60 minutes in a hour.)
0.16x60=9.6
9514 1404 393
Answer:
(b) 48
Step-by-step explanation:
In this geometry, the altitude (x) is the root of the product of the segments of the hypotenuse.
x = √(36·64) = √36×√64 = 6×8
x = 48
_____
All of the triangles are similar, so the ratios of corresponding sides are the same.
short side/long side = x/64 = 36/x
x^2 = (64)(36) . . . . as above
Answer:
the gradient is the same= 4
the y intecept is different, one is positive 1 and the other is negative 3
I THINK its 2. :) Hope i'm right.
