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:
49
Step-by-step explanation:
Ashley sold 98 small cups and 57 large cups of lemonade.
Step-by-step explanation:
Given,
Price of small cup of lemonade = $1.25
Price of large cup of lemonade = $2.50
Total cups sold = 155
Total worth of cups = $265
Let,
x represent the number of small cups sold
y represent the number of large cups sold
According to given statement;
x+y=155 Eqn 1
1.25x+2.50y=265 Eqn 2
Multiplying Eqn 1 by 1.25
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 1.25
Putting y=57 in Eqn 1
Ashley sold 98 small cups and 57 large cups of lemonade.
