I need help on my math homework
xxTIMURxx [149]

Answer: the first one is True and the second one is false

Step-by-step explanation:

3 + 5x = 23

so replace x with 4 you get 3 + 5 * 4 = 3 + 20 = 23

this is equal to 23 so it is true

2x - 6 = 9

do the same you get

2 * 8 - 6 = 9

16 - 6 = 10

the answer is 10 not nine therefore it is false

The area of the sector is
.. Asector = (1/2)r^2*θ = (1/2)*(8.35 ft)^2*(π*260°/180°) ≈ 158.195 ft^2

The area of the triangle is
.. Atriangle = (1/2)r^2*sin(θ) = (1/2)*(8.35 ft)^2*sin(100°) ≈ 34.332 ft^2

The shaded area is
.. A = Asector +Atriangle
.. = 158.195 ft^2 +34.332 ft^2
.. ≈ 192.5 ft^2

In a football tournament, the Bees scored 9 less than three times as many points as the Hornets. The Wasps scored 28 more points
Alinara [238K]

Answer:

  • <u>The Bees scored 90 points.</u>

Explanation:

First, let's prove that the equation is correct.

To create the equation, you translate the verbal statements into algebraic expressions.

Since, it is said that x respresents the number of points scored by the Hornets, that is your variable and all the verbal statements will be translated using x:

a) NUmber of points scored by the Hornets: x

b) The Bees scored 9 less than three times as many points as the Hornets ⇒v3x - 9

c) The Wasps scored 28 more points than the Hornets ⇒ x + 8

d) Together the three teams scored 184 points ⇒

 

  • x + (3x - 9) + (x + 28) = 184

Which indeed is the given equation: (3x – 9) + x + (x + 28) = 184

Now, complete the steps to show it, in the same order given:

<u>1. Combine like terms. </u>

  • Remove the parenthesis: x + 3x - 9 + x + 28 = 184

  • Combine the terms on x on the left: x + 3x + x = 5x

  • Combine the constants on the left: - 9 + 28 = 19

  • Write the result: 5x + 19 = 184

<u>2. Use the subtraction property of equality. </u>

  • Subtract 19 from both sides: 5x + 19 - 19 = 184 - 19

  • Due the operations: 5x = 165

<u>3. Use the division property of equality. 4. </u>

  • Divide both sides by 5: (5x / 5) = 165 / 5

  • Due the operations: x = 33

<u>4. Use the variable to answer the question. How many points did the Bees score?</u>

  • The expression for the points scored by the Bees is 3x - 9, so substitute x in that expression: 3 (33) - 9 = 99 - 9 = 90.

  • Answer: the Bees scored 90 points.
