Answer:
x = 14
Step-by-step explanation:
5x - 40 = 30
+40 +40
5x = 70
divide by 5 on both sides
x= 14
Answer:
D
Step-by-step explanation:
14.34 x 21 - 2.40 x 7 = 284.55
Lets solve the problem through compound interest formula,
The number of months are 360
The account pay interest rate is 5.1 %compounded monthly.
The amount withdraws each month is $2154
The value of n is 360.
The value of is<em> i</em> is 5.1%
So,
![P = A [(1+i)^n]-1/i(1+i)^n\\\\P = $2,154 [(1+(0.051/12))^30*12] - 1 / (0.051/12)(1+(0.051/12))^30*12\\\\P = $396,721.78](https://tex.z-dn.net/?f=P%20%3D%20A%20%5B%281%2Bi%29%5En%5D-1%2Fi%281%2Bi%29%5En%5C%5C%5C%5CP%20%3D%20%242%2C154%20%5B%281%2B%280.051%2F12%29%29%5E30%2A12%5D%20-%201%20%2F%20%280.051%2F12%29%281%2B%280.051%2F12%29%29%5E30%2A12%5C%5C%5C%5CP%20%3D%20%24396%2C721.78)
Hence the value of principal is $396721.78

Answer:
The answer is y = -15x + 35.
Step-by-step explanation:
We want to isolate y, so we cancel everything on that side of the equals except y. We begin with the term farthest away from y, which would be 3x. Since it is positive, to cancel it we will subtract. This will give us 1/5y = 7-3x.
Next we want to cancel the 1/5. Since it is directly beside y, this means it has been multiplied; to cancel, we will divide. Divide both sides by 1/5, and we have y = (7-3x)÷(1/5). When we divide fractions, we flip the second one and multiply; this means we have y=(7-3x)*5.
Using the distributive property, we have y=7*5-3x*5, which gives us y=35-15x. We can write this as y=-15x+35.
