Step-by-step explanation:

both halves of a diagonal must be equal.

so,

8b - 30 = 6b + 6

2b = 36

b = 18

and

9a - 13 = 5a + 5

4a = 18

a = 18/4 = 4.5

Dear Mathee2, you can do 1/10+1 8/10≈2 and 1/20+1 19/20≈2. Note: you said fractions, so did you want the fractions to be mixed numbers or improper fractions?

Find the slope between 2 points. <br> (16, 12) (40,18)

WITCHER [35]

Answer:

$\frac{1}{4}$

Step-by-step explanation:

In this question, we have to find the slope with the given coordinates.

To find our slope, we would use the slope formula: $m = \frac{y2-y1}{x2-x1}$

Plug in your coordinates and solve:

$m = \frac{18-12}{40-16}\\\\m=\frac{6}{24}$

Simplify the fraction:

$m=\frac{1}{4}$

The slope would be $\frac{1}{4}$

If you place a 26-foot ladder against the top of a 10-foot building, how many feet will the bottom of the ladder be from the bot

True [87]

Answer:

24 foot

Step-by-step explanation:

We are given that

Length of ladder=26 foot

Height of building=10 foot

We have to find the distance between the bottom of ladder and the bottom of building.

Pythagorus theorem:

$(Hypotenuse)^2=(Base)^2+(Perpendicular\;side)^2$

We have hypotenuse =AC=26 foot

Perpendicular side =AB=10 foot

Base=BC

Substitute the values in the given formula

$(26)^2=(10)^2+(BC)^2$

$676=100+(BC)^2$

$(BC)^2=676-100=576$

$BC=\sqrt{576}=24$ (Take positive because length is always positive)

BC=24 foot

Hence, the bottom of the ladder will be 24 foot from the bottom of the building.
