Answer:

\frac{7}{4}

Step-by-step explanation:

Here is the complete question: 28 elementary schools to 16 middle schools, write the ratio in simplest form.

Given ratio= elementary schools: middle schools:: 28:16

The ratio can be written as \frac{28}{16}

Now to write \frac{28}{16} into simplest form, we need to divide both numerator and denominator by 4.

∴ elementary schools: middle schools= \frac{\frac{28}{4} }{\frac{16}{4} }

Hence, we get simplest ratio of elementary schools to middle schools= \frac{7}{4}

What is the slope- intercept form of 4x+5y=20
True [87]

Answer:

y = -4/5x + 4

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Equality Properties

<u>Algebra I</u>

Standard Form: Ax + By = C

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Step-by-step explanation:

<u>Step 1: Define</u>

Standard Form:   4x + 5y = 20

<u>Step 2: Rewrite</u>

  1. Subtract 4x on both sides:                    5y = 20 - 4x
  2. Divide 5 on both sides:                          y = 4 - 4/5x
  3. Rearrange:                                              y = -4/5x + 4

The diagram shows a right-angled triangle.<br> a<br> 12 cm<br> 24 cm<br> Find the size of angle x.
Vlada [557]

Given that , Length of Base and Hypotenuse is 12 cm and 24 cm , respectively .

Need To Find : The measure of Angle x .

<em>As </em><em>We </em><em>know </em><em>that </em>,

Cos ∅ = Base / Hypotenuse

ㅤㅤ <u>By </u><u>Substituting </u><u>known </u><u>Values </u><u>:</u>

ㅤ⤀Cos x = 12/24

ㅤ⤀Cos x = ½

ㅤ⤀Cos 60⁰ = ½

Therefore,

  • Value of Angle x is 60⁰

AnnZ [28]

Hi!

Step-by-step explanation:

SLOPE=\frac{Y_2-Y_1}{X_2-X_1}=\frac{RISE}{RUN}

\frac{(-18)-(-18)}{(-15)-12}=\frac{0}{-27}=0

<u><em>Slope is 0.</em></u>

<u><em>The answer is 0.</em></u>

Hope this helps!

Have a nice day! :)
