The two equations are
$x + y = 7$
and
$4x + 2.5y = 22$
the first equation can be solved for x to be
$x = 7 - y$
next you can substitute x in the second equation
$4(7 - y) + 2.5y = 22$
Distribute 4 to everything in the parentheses
$28 - 4y + 2.5y = 22$
combine like terms:
$28 - 1.5y = 22$
subtract 28 from both sides of the equation
$- 1.5y = - 6$
divide both sides by -1.5
$y = 4$
plug this in to the original equation of x+y=7
$x + 4 = 7$
subtract 4 from both sides.
$x = 3$

X =<br>Angle measure <br>in the following picture solve for x

rjkz [21]

Answer:

x=11

Step-by-step explanation:

3x+28+5x+52+12=180

8x+92=180

-92 on both sides

8x=88

/8 on both sides

x=11

(Figure is provided below)

DanielleElmas [232]

Answer:

The measure of ∠z = 137°

Step-by-step explanation:

Here, angle 1 = 43°

To find : ∠z

Straight line Angle: The angle which measures exactly 180° and is extended by a point on a straight line is called straight angle.

According to the given figure:

∠1 + ∠z = 180 ° (STRAIGHT LINE ANGLE)

or, ∠z = 180 ° - 43° = 137°

Hence, the measure of ∠z = 137°.

Can the three angles 25 65 and 90 create one unique triangle

Serhud [2]

Answer:

Yes, it can. Triangles [in order for them to be one] must equal 180. If you add all of these angles together, since a triangle only has three angles anyway, it equals to 180, so you know it's a triangle.

If this was confusing, I am happy to help further!

What is the distance in the standard (x, y) coordinate<br> plane between the points (2,3) and (5,5)?

Naddik [55]

<h3>The distance between the points (2,3) and (5,5) is 3.6 units</h3>

<em><u>Solution:</u></em>

<em><u>Distance between two points is given by:</u></em>

$d=\sqrt{\left(x_{2}-x_{1}\right)^{2}+\left(y_{2}-y_{1}\right)^{2}}$

We have to find the distance in the standard (x, y) coordinate plane between the points (2,3) and (5,5)

From given,

$(x_1, y_1) = (2, 3)\\\\(x_2, y_2) = (5, 5)$

Substituting the values we get,

$d = \sqrt{(5-2)^2 + (5-3)^2}\\\\Simplify\\\\d = \sqrt{3^2 + 2^2}\\\\d = \sqrt{9+4}\\\\d = \sqrt{13}\\\\In\ decimal\ form\\\\d = 3.605 \approx 3.6$

Thus distance between the points (2,3) and (5,5) is 3.6 units
