Answers:

Question 1: y = 5

Question 2: x < 1.6666667

Step-by-step explanation:

<h3>Question 1:</h3>

We have the equation 5x - 2y = 30.

Now, we have to subtract 5x from both sides of the equation.

-2y = -5x + 30

Next, we have to divide the numbers.

y = 2.5x - 15      

Make sure to put in the value of x.

y = 2.5 (8) - 15          

We have to multiply now.

y = 20 - 15      

20 - 15 = 5,

y = 5

<h3>Question 2:</h3>

We have the equation 12x - 4 < 16.

Add 4 to both of the sides of the equation.

12x < 20

Divide the numbers.

x = 20 ÷ 12

20 ÷ 12 = 1.66666667

Hope this helps you!

Trevor and $826 on account during 2.5% annual interest for seven years.
photoshop1234 [79]

Trevor invested $ 4720

<em><u>Solution:</u></em>

Given that, Trevor earned $ 826 on account during 2.5% annual interest for seven years

We can simple interest formula

<em><u>The formula for simple interest is given as:</u></em>

\text{ Simple Interest } = \frac{p \times n \times r}{100}

Where,

"p" is the principal

"n" is the number of years

"r" is the rate of interest

Here given that,

Principal = p = ?

rate of interest = r = 2.5 %

number of years = n = 7

Simple interest earned = 826

<em><u>Substituting the values in above formula,</u></em>

826 = \frac{p \times 7 \times 2.5}{100}\\\\82600 = p \times 7 \times 2.5\\\\82600 = 17.5p\\\\p = \frac{82600}{17.5}\\\\p = 4720

Thus he invested $ 4720

to estimate the speed of a car, v, in miles per hour, based on the length, L, in feet, of its skid marks when suddenly braking o
Leno4ka [110]

Answer:

69.6 miles per hour

Step-by-step explanation:

Length of the skid marks = 242 feet

The formula used for the velocity is

v=2\sqrt{5L}

where, L is the length of skid marks in feet and the velocity obtain has the units of miles per hour.

By substituting the value

v=2\sqrt{5\times 242}

v = 69.6 miles per hour

Thus, the speed of the car at the time of accident is 69.6 miles per hour.

In the figure below, if angle T measures 130 degrees, what is the measure of angle Q?
krek1111 [17]

Circle theorem:

The angle at the centre (T) is double the angle at the circumference (Q)

---> That also means that:

The angle at the circumference (Q) is <u>half</u> the angle at the centre (T)

Since T = 130 degrees;

Q = 130 divided by 2

   = 65°

___________________________________

Answer:

∠Q = 65°
