Find the value of x. 3x, 2x, 55

Mathematics
1 answer:
SOVA2 [1]3 years ago
7 0

The sum of the measures of the angles in a triangle is 180°.

Therefore we have the equation:

2x° + 3x° + 55° = 180°

5x° + 55° = 180°    <em>subtract 55° from both sides</em>

5x° = 125°     <em>divdie both sides by 5</em>

x° = 25°

<h3>Answer: x = 25</h3>

Find the midpoint of the two points
inna [77]
<h3>Answer: D.  (2, 21)</h3>

Explanation:

Imagine that your teacher wanted you to find the midpoint of -3 and 7 on the number line. To do this, you would add up the given values and divide by 2.

(-3+7)/2 = 4/2 = 2

The value 2 is right in the middle of -3 and 7 on the number line. This result is also the x coordinate of the midpoint since the values I used were the x coordinates of the original points.

The y coordinates are handled the same way:

(18+24)/2 = 42/2 = 21

The y coordinate of the midpoint is y = 21

Overall, the midpoint is (2, 21)

Correct statement and question:

The equation A = 1750(1.04)^t represents an account balance t years after the  account was created.

Which statement is correct?

A. The account balance will decrease 0.04% each year.

B. The account balance will increase 0.04% each year.

C. The account balance will decrease 4% each year.

D. The account balance will increase 4% each year.

Source:

Tennessee Comprehensive  Assessment Program  - Algebra I Practice Test

Step-by-step explanation:

Let's recall that 1.04 is the result of adding:

1 + 0.04 and, we can also write 0.04 as 4/100 or 4%,

in consequence,

1.04 = 1 + 4%, where we're increasing an additional 4%.

<u>The correct statement is D. The account balance will increase 4% each year.</u>
