The second to last statement: he needed to divide both sides of the equation by 5

Since we want to isolate a, which is multiplied to 5, we want to do the opposite which is divide by 5.

8,|3 |,-5,| -2 |,-2

Ronch [10]

When a number has the |absolute value|, it refers to the amount of units the number is from 0. (you can think of a timeline)
|3| is 3 units away from zero
|-5| is 5. it is NOT -5 units from 0, since a number cannot be -5 units away.
Basically, these lines | x | will make the number positive.

answer
-5,-2, | -2 |, | 3 |, 8

Find the midpoint between two points on a coordinate plane whose coordinates are (5.7) and (-3, 1).

jok3333 [9.3K]

Answer:

(1,4)

Step-by-step explanation:

$if~(x,y)~is~mid~point~of~(x_{1},y_{1})~and~ (x_{2},y_{2}~then\\x=\frac{x_{1}+x_{2}}{2} \\y=\frac{y_{1}+y_{2}}{2} \\x=\frac{5-3}{2} =\frac{2}{2}=1\\y=\frac{7+1}{2} =\frac{8}{2} =4$

(x,y)→(1,4)

Lyra's speed of travel is 6.71 feet per seconds and Lyra's direction of travel is 27 degrees north of east

<h3>How to determine the speed of travel?</h3>

The diagram that represents the scenario is added as an attachment.

Let x represents Lyra's speed of travel.

The value of x is calculated using the following Pythagoras theorem.

$x = \sqrt{3^2 + 6^2}$

Evaluate the exponents

$x = \sqrt{9 + 36}$

Evaluate the sum

$x = \sqrt{45}$

Evaluate the exponent

x = 6.71

Hence, Lyra's speed of travel is 6.71 feet per seconds

<h3>How to determine the direction of travel?</h3>

The direction (∅) is calculated using the following tangent ratio.

$\tan(\theta) = \frac 36$

Evaluate the quotient

$\tan(\theta) = 0.5$

Take the arc tan of both sides

$\theta = \tan^{_1}(0.5)$

Evaluate

$\theta = 27$

Hence, Lyra's direction of travel is 27 degrees north of east

A number t decreased by 2 is at least 7

9966 [12]

Answer:
t - 2 ≥ 7; t ≥ 9

Explanation:
“a number t” = t
“decreased by 2” = - 2
“Is at least 7” = ≥ 7
So, t - 2 ≥ 7

To solve for t - 2 ≥ 7, add 2 to both sides of the equation

t - 2 ≥ 7
t - 2 + 2 ≥ 7 + 2
t ≥ 9

So, t ≥ 9
