Which first step for solving the given system using substitution results in an equation without fractions?

1 answer:

5 0

The correct answer is solve for y in the second equation.

Step 1: Multiply each equation by a suitable number so that the two equations have the same leading coefficient. ...
Step 2: Subtract the second equation from the first.
Step 3: Solve this new equation for y.
Step 4: Substitute y = 2 into either Equation 1 or Equation 2 above and solve for x.

Answer:

Step-by-step explanation:

6) 15 + 2x = 75 Check: 15 + 2x = 75

2x = 75 - 15 15 + 2*30 = 75

2x = 60 15 + 60 = 75

x = 60/2 75 = 75

x = 30

7) m/3 - 14 = 10

m/3= 10 + 14

m/3 = 24

m = 24 *3

m = 72

Find the unit rate.<br> 80 rooms on 5 floors<br> =<br> =<br> rooms per floor<br> Submit

Ganezh [65]

<h3>The formula to find unit rate is:</h3>

<em>divide the denominator with the numerator in a way that the denominator becomes 1</em>

$\begin{gathered}\\ \sf\longmapsto \frac{80}{5}\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto\cancel{\dfrac{80}{5}} \end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 16\end{gathered}$

<u>Hence, The unit rate is 16 rooms per floor.</u>

Directions: Find the complemen

andre [41]

Given:

The angles are:

Example $54^\circ$

1. $63^\circ$

2. $87^\circ$

3. $45^\circ$

4. $72^\circ$

5. $5^\circ$

To find:

The complimentary angle of the given angles.

Solution:

If two angles are complimentary, then their sum is 90 degrees.

Example: Let x be the complimentary angle of $54^\circ$ , then

$x+54^\circ=90^\circ$

$x=90^\circ -54^\circ$

$x=36^\circ$

Similarly,

1. The complimentary angle of $63^\circ$ is:

$90^\circ -63^\circ=27^\circ$

2. The complimentary angle of $87^\circ$ is:

$90^\circ -87^\circ=3^\circ$

3. The complimentary angle of $45^\circ$ is:

$90^\circ -45^\circ=45^\circ$

4. The complimentary angle of $72^\circ$ is:

$90^\circ -72^\circ=18^\circ$

5. The complimentary angle of $5^\circ$ is:

$90^\circ -5^\circ=85^\circ$

Therefore, the complimentary angles of $54^\circ, 63^\circ, 87^\circ, 45^\circ, 72^\circ, 5^\circ$ are $36^\circ, 27^\circ, 3^\circ, 45^\circ, 18^\circ, 85^\circ$ respectively.
