Geometric Shapes - Part 1

Mathematics
1 answer:
Softa [21]2 years ago
3 0

Answer:

x = 54, so the vertical angles are 110°.

Step-by-step explanation:

2x + 2 = 3x - 52

2  = x - 52

x = 54

2(54) + 2 = 108 + 2 = 110

3(54) - 52 = 162 - 52 = 110

Quick algebra 1 question for 10 points!
valina [46]

<u>Answer:</u>

○ 1 hour 41 minutes or more

<u>Step-by-step explanation:</u>

We can make two equations that represent the total amount each plumber charges.

If x represents the number of hours they work, then:

•Total charged by Plumber A = 35 + 15x

• Total charged by Plumber B = 40+12x

Now, if Plumber A is more expensive than Plumber B, then:

Total charged by Plumber A > Total charged by Plumber B

∴ 35 + 15x > 40+12x

Now all we have to do is solve for x:

35 + 15x > 40+12x

⇒ 35 + 15x -12x > 40

⇒ 35 + 3x > 40

⇒ 3x > 5

⇒ x > \bf \frac{5}{3} \space\ \mathrm{h}

\frac{5}{3} \space\ \mathrm h  is equivalent to  \frac{5}{3} \times 60 \space\ \mathrm {min} = 100 minutes, which is the same as 1h 40min.

This means if Plumber A works more than 1h 40min, they become more expensive than Plumber B.

More than 1h 40min is equivalent to '1 hour 41 minutes or more', therefore the first option is correct.

Ms Liu uses her bank card to purchase gasoline 5 times in one month Each time she purchases gasoline, the cost is $15.85 What is
dlinn [17]

Answer:

x - 79.25

Step-by-step explanation:

Let x represent the original amount of money that Ms. Liu had in her bank account.

Find how much money she spent on gasoline, by multiplying 15.85 by 5:

15.85(5)

= 79.25

To represent how much money she will have left, subtract this from x:

x - 79.25

So, the expression to find the change in her account is x - 79.25

Solve -2 x + 12 &lt; -4
natka813 [3]

Answer:

x > 8

Explanation:

−2x + 12 < −4

[<em> Subtract 12 from both sides </em>]

−2x + 12 − 12 < −4 − 12

−2x < −16

[ <em>Divide both sides by -2 </em>]

-2x / -2 < -16 / -2

x > 8
