Solve for x please ????

Mathematics
1 answer:
3241004551 [841]3 years ago
8 0

Answer:

Step-by-step explanation:

First, subtract 180 and "12x-3", which equals 180-12x+3

Then add 46, "5x+7", and "180-12x+3"

46+5x+7+180-12x+3 = 180

Since the degrees in a triangle add up to 180 degrees, cancel out the 180 degrees from this side "180-12x+3" and the other side "180"

46+5x+7-12x+3=0

46+10-7x=0

56=7x

X = 8

How long would you need to earn interest on $350 invested at 5.5% in order to earn $154 in interest
Fed [463]

Answer:

8 years.

Step-by-step explanation:

The simple interest formula is principal × rate (as a decimal) × time = interest. In this question, you want to find the time.

First, plug in your numbers. 350 × .055 × t = 154. Then, to find t, divide to get t one side.

t = 154 / 350 × .055

Then solve.

350 × .055 is 19.25. 154 / 19.25 is 8.

So, your answer is 8 years.

154/350*.055 = t

if there are 2040 seats in a section of a stadium, 20 seats in the first row, and 4 more seats in each row, how many rows are th
Lorico [155]


2040 = n/2(20+(n-1)4)

4080 = n(20+4n-4)

4080= 20n +4n^2 -4n

1020 = 4n + n^2

n^2 +4n -1020 =0

use common formula (can't write out so just look at answers. sorry)

which gives answers of n=-34 and n=30. since n can only be positive, n=30 so there are 30 rows. I liked that challenge
