The expression can be written as:
(2x + 5) - 3
or:
5 + (2x - 3)

Answer:
![\boxed {\boxed {\sf A. \ 18}}](https://tex.z-dn.net/?f=%5Cboxed%20%7B%5Cboxed%20%7B%5Csf%20A.%20%5C%2018%7D%7D)
Step-by-step explanation:
The two angles are inside a right angle. The small box signifies a right angle/ 90° angle.
Therefore, the sum of the angle measures must equal 90. We can set up an equation.
![56+(x+16)=90](https://tex.z-dn.net/?f=56%2B%28x%2B16%29%3D90)
Combine the like terms on the right side. The 2 constants: 56 and 16 can be added.
![(56+16)+x=90\\](https://tex.z-dn.net/?f=%2856%2B16%29%2Bx%3D90%5C%5C)
![72+x=90](https://tex.z-dn.net/?f=72%2Bx%3D90)
Since we are solving for x, we must isolate the variable. 72 and x are being added. The inverse of addition is subtraction, so subtract 72 from both sides.
![72-72+x=90-72](https://tex.z-dn.net/?f=72-72%2Bx%3D90-72)
![x=18](https://tex.z-dn.net/?f=x%3D18)
x is equal to 18 and choice A is correct.
They are not equivalent fractions. You will have to turn 3/4 into an 8th, so multiply it by two, (6/8) and plot that on a graph.
Answer:
y - 4 =
(x - 7)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (2, 3) and (x₂, y₂ ) = (7, 4)
m =
= ![\frac{1}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7D)
Use either of the 2 points for (a, b)
Using (7, 4), then
y - 4 =
(x - 7) ← in point- slope form
