Answer:
A) x = 12
Step-by-step explanation:
if its a right angle? then the angle in total is 90 degrees,
subtract the 35 from 90 to get 55 degrees,
4x + 7 = 55 solve this
4x = 48
x = 12
If we try to simplify the ratio or try to multiply both by any number, we will get the equivalent ratio
Like :

Divide ( simplify ) by 2

Or multiply by any number,

From the example, 2 / 3 and 8 / 12 are equivalent ratios to 4 / 6
.003 is 1/10 of .03. To find it divide by 1/10
Answer:
Latisha rode 16 rides
Step-by-step explanation:
Look at picture attached. Have a blessed night!
Just slope intercept formula (y=mx+b). X represents the number of rides so you will need to myltiply that by $2.50. $9 is a one time fee so that would be of the b of the equation. That all equals the total Latisha piaid, $49. Then solve like so.
Given that

attains a maximum at

, it follows that

at that same point. So integrating once gives



and so the first derivative is

.
Integrating again, you get


You know that this curve passes through the point (2, -1), which means when

, you have

:


and so
