Solve each equation. Check your solution. 4t - 2 = 14

anyanavicka [17]

T = 4. first, you can add 2 to both sides of the equation. you get 4t = 16. then, you can divide both sides by 4 to isolate t.

Please look at this multiple choice, thanks!

Nastasia [14]

Step-by-step explanation:

$\frac{y - y1}{x - x1} = \frac{y2 - y1}{x2 - x1}$

$\frac{y - 0}{x - ( - 1)} = \frac{3 - 0}{1 - ( - 1)}$

$\frac{y}{x + 1} = \frac{3}{1 + 1}$

$\frac{y}{x + 1} = \frac{3}{2}$

$y = \frac{3}{2} (x + 1)$

$y = \frac{3}{2} x + \frac{3}{2}$

option B

An instructor asked her students how much time (to the nearest hour) they spent studying for the midterm. The data are displayed

BARSIC [14]

Based on the data displayed in the histogram, the percentage of students who study 2 or more hours for the midterm is 88%.

<h3>What percentage study 2 hours or more?</h3>

First, find the number of students studying:

= 3 + 9 + 6 + 3 + 2 + 1 + 1

= 25

The number of students studying 2 or more hours for the exam are:

= 9 + 6 + 3 + 2 + 1 + 1

= 22 students

The percentage studying for two hours or more is:

= 22 / 25

= 88%

What is |-8| ? -16

olga nikolaevna [1]

Answer:

Those little "sticks" are called absolute value.

For example, the absolute value of 2 is 2, and the absolute value of −2 is also 2. The absolute value of a number may be thought of as its distance from zero along real number line.

Thus, it doesn't matter if the number is positive or negative. As it only counts its distance from 0, on the number line.

I hope it helps.
