The correct answer is y= |x + 1| - 3
Answer:
105 degrees
Step-by-step explanation:
To start this think about what you know has to be true about this:
- Angle WRQ and PRQ when added will equal 180
- Triangle PRQ when all the angles are added will equal 180
- We have to find x to find what the angle measure of angle WRQ is
So let's start to write an equation:
Let's say angle PRQ is y.
20x + 5 + y = 180
27 + y + 14x + 8 = 180
Now let's use substitution to solve for y:
20x + 5 + y = 180
subtract 5 from both sides:
20x + y = 175
subtract 20x from both sides:
y = -20x + 175
Let's now plug in y to our other equation:
27 + (-20x + 175) + 14x + 8 = 180
now combine all like terms:
-6x + 210 = 180
now solve for x:
subtract 210 from both sides:
-6x = -30
divide both sides by -6:
x = 5
Now that we have x, let's plug it in for the equation of angle WRQ:
20(5) +5
Simplify:
105
Hope this helps!
Answer:
x = 5, y = 20
Step-by-step explanation:
if y = 4x and 3x+2y = 55 then we can subtitude y as x.
We know that y = 4x so we can write 4x wherever we see y.
3x + 2y = 3x + 2(4x) = 55
3x + 8x = 55
11x = 55
x = 5.
And if y = 4x = 4(5)
y = 20
Answer:
A.
Step-by-step explanation:
Step 1: We know .3333... is , we rewrite the equation as
Therefore the answer would be A.
9.75 x 20 =$195
9.25 x 20= $185
