Using the cross product property on this proportion gives us the following equation:
20 (2x - 9) = 10 (9)
Use the distributive property and multiply
40x - 180 = 90
Add 180 to both sides
40x = 270
Divide 40 from both sides
x = 270/40
Simplify fraction
x = 27/4
This should be your answer. Let me know if you need any clarifications, thanks!
Answer:
Slope is 4 Y intercept is -5
Step-by-step explanation:
Y intercept is always the second number, and the slope is always with the x after. Also Y=MX+B
Answer:
m=-3/5
Step-by-step explanation:
Answer:
y=474+2x
y=350+4x
Answer: x=62 y=598
Step-by-step explanation:
Place the two equations equal to each other.
350+4x=474+2x
Then Subtract 350 from 474 which gets you to 124.
4x=124+2x
Then subtract 2x from both sides.
Which make the equation look like this: 2x=124
Now divide 124 by 2.
so x=62.
Then you will need to plug in x in one of the equations to know what y is.
I plugged it into this one: y=474+2(62)
Now solve.
It should get you to the answer of 598.
So, overall x=62 while y=598.
The length is 3m. You do the area(45) divided by the width(15) to hey the length, which is 3.
