Mathematics
1 answer:
denis-greek [22]2 years ago
4 0

If y is substitute into either of the original equation. The  solution as an ordered pair are: x=-2; y=3.

<h3>The solution as an ordered pair</h3>

x + 3y= 7 equation 1

x+2y=4 equation 2

Solving for y

x+3y-(x+2y)=7-4

x+3y-z-2y=7-4

3y-2y=7-4

y=7-4

y=3

Substitute y=3 into equation 2

x+2y=4

x+2×3=4

x+6=4

Collect like terms

x=4-6

x=-2

Therefore the  solution as an ordered pair are: x=-2; y=3.

Two angles are supplementary . The measure of one angle exceeds three times the measure of the other angle by 32. What is the de
kaheart [24]

Let the two angles be 'x' and 'y'.

Since, the angles are supplementary.

When the angles are supplementary, then the sum of the measures of the angles is 180 degrees.

x + y = 180^\circ        (Equation 1)

Since, the measure of one angle exceeds three times the measure of the other angle by 32.

x = (3 \times y) + 32

x = 3y + 32

Substituting the value of 'x' in equation 1, we get

x+ y = 180^\circ

3y+32+ y = 180^\circ

4y+32 = 180^\circ

4y= 180-32

4y = 148^\circ

y = 37^\circ

So, the measure of the smaller angle is  37^\circ.

erik [133]
Use similar triangles (see the picture I drew at the bottom)

\frac{6.3}{13.8} = \frac{18.9}{x} \\6.3x=(13.8)(18.9)\\6.3x=260.82\\x=41.4
