What value of x makes the equation true?​

What Value Of X Makes The Equation True?

Answers

Answer 1

Answer:

x = 9/4

Step-by-step explanation:

-3x + 10 = 5x - 8

Add 3x to both sides

10 = 8x - 8

Add 8 to both sides

18 = 8x

Divide both sides by 8

18/8 = x

Reduce

9/4 = x

x = 9/4

Sum of the Angles of a Triangle

If the three angles of a triangle

are equal, what is the

measurement of each angle?

B

C

[?] degrees

Answers

9514 1404 393

Answer:

  60°

Step-by-step explanation:

If the measure of the angle is represented by A, then the sum of the three angles in the triangle is ...

  A +A +A = 180°

  3A = 180° . . . . . . . simplify

  A = 180°/3 = 60° . . . . . divide by the coefficient of A

The three angles in an equi-angular triangle are all 60°.

__

Additional comment

If the angles are equal, so are the opposite sides. The three sides in an equi-angular triangle are also equal. Generally, such a triangle is called an equilateral triangle. It is useful to remember the angles in an equilateral triangle are all 60°.

One interesting consequence of this is that the smallest angle in any triangle can never be larger than 60°.

In right triangle EAD with right angle at A, AE=4 units, AB=BC=CD and the area of triangle ABE=6 sq units. What is the length of segment CE? Express your answer as a decimal to the nearest tenth.

Answers

Answer:

CE = 7.2

Step-by-step explanation:

Area = 1/2bh

6 = 1/2 (b)(4)

6 = 2b

3 = b     b represent AB, so BC and CD is 3 unit also

Length of CE , you have a right triangle with a leg(AE) = 4 and and the other leg (AC) = 6 and the hypotenuse (CE) = x

The figure is a right triangle so you know that a² + b² = c²

4² + 6² = x²

16 + 36 = x²

52 = x²

[tex]\sqrt{52 }[/tex] = x

7.211 ≈ 7.2 = CE

Scrooge invests $500. He found a bank that would pay him 4% interest, compounded monthly.
a) Type of exponential function.

b) Write a function to represent the situation.

c) If he deposits the whole $500 and does not deposit or withdraw any other amount, how much money would he have after 4 years?

Answers

The exponential function is a growth function. The exponential function that represents the situation is: A(1 +r)^nm. The amount of money that Scrooge would have in 4 years is $586.60.

The formula that can be used to determine the amount Scrooge would have in 4 years is: A(1 +r)^nm

A = Amount invested = $400

r = interest rate = 4/12 = 0,0333

n = number of years

m = number of compounding

$500(1.0333)^(12 x 4) = $586.60.

is -3/2 parallel to 2/3

Answers

Answer: The parallel slope of 2/3 is 2/3 .   m=2/3

Step-by-step explanation: Parallel slopes have the same slopes.

If a slope is 2/3, the parallel slope will be the same. So, the parallel slope will also be 2/3.

Therefore, the answer is m=2/3

Answer:

No.

Step-by-step explanation:

Parallel lines have the same slope. Perpendicular lines have opposite reciprocal slopes. In this instance, -3/2 is perpendicular to 2/3, not parallel.
