Hope I helped. If so, may I get brainliest and a thanks?
Thank you, have a good day!
so.. as you can see, we use the decimal notation for the percentages... 65% is just 65/100 and 50% is just 50/100 and so on
so.. whatever the salted amounts are, we know they'll add up to (x+175)(0.50)
thus (0.30x) + (175)(0.65) = (x+175)(0.50)
solve for "x"
Question 1 - the first choice is right
Question 2- the first choice also
Jennifer would have $580 in her account after 24 months
a(x) = 20x + 100
the above function is a linear function
A linear function is a function that has a single variable raised to the power of 1.
100 is the constant
20 increases by m
a(x) is the dependent variable. Its value depends on the amount deposited per month and the number of months
The amount she would have after 24 months =
20(24) + 100 = $580

Answer:x=31
angle AOC = 124
angle BOC = 56
Step-by-step explanation:
We first need to solve for x to solve the rest. We would normally solve for x by setting 2 equations equal to each other, in this case however, we know that the two angles are adjacent and in total add up to 180. Therefore we combine like terms of both angles, and set them equal to 180.
So, we do
3x+31+2x-6=180 We will combine like terms
5x+25=180 Now we will do inverse operations
5x=155
x=31
We plug x into angle AOC to solve for it
3(31)+31= 124
180-124=56 or angle BOC because the whole angle is 180, and if we subtract 124 from 180 we get the remainder which is angle BOC
Or if you want,
2(31)-6=56
