Answer: 12
Step-by-step explanation:
difference = subtraction
and = addition
times = multiplication
Therefore,
7x - 4 = 80
7x = 84
x = 12
Answer: 26ft

Answer:
Step-by-step explanation:
<u>Equation of a Line</u>
Two variables x and y are linearly dependent when they are related by the equation
where m is the slope and b is the y-intercept, or the value of y when x equals 0. We are given a particular equation for the line such as b=0, so we only need one point to compute m. That point is (-1,-2):
It follows that
Thus the equation of the line is
Answer:
m = 6√3

- [Right Triangles Only] cos∅ = adjacent over hypotenuse
Step-by-step explanation:
<u>Step 1: Define</u>
We are given a right triangle. We can use trig to find the missing side length.
<u>Step 2: Identify Variables</u>
<em>POV from angle measure</em>
Angle = 30°
Adjacent Leg = <em>m</em>
Hypotenuse = 12
<u>Step 3: Solve for </u><em><u>m</u></em>
- Substitute [cosine]: cos30° = m/12
- Isolate <em>m</em>: 12cos30° = m
- Evaluate: 10.3923 = m
- Rewrite: m = 6√3

Answer:
VW = 44
Step-by-step explanation:
the line VX is parallel to ZY and intersects the other 2 sides of the triangle then it divides those sides proportionally , that is
= ( substitute values )
= = ( cross- multiply )
VW = 2 × 22 = 44
