Answer:
1. x = 15°
2. y = 12
Step-by-step explanation:
1. Determination of the value of x.
(5x – 5) + 110 = 180 (Adjacent angles add up to 180)
5x – 5 + 110 = 180
5x + 105 = 180
Collect like terms
5x = 180 – 105
5x = 75
Divide both side by 5
x = 75/5
x = 15°
2. Determination of the value of y.
3y – 4 = 2y + 8 (opposite sides are equal)
3y – 4 = 2y + 8
Collect like terms
3y – 2y = 8 + 4
y = 12

jelly beans must be given to Vicki so that they each have the same number
of jelly beans? Express your answer in lowest terms.
Answers
Answer:
2/5
Step-by-step explanation:
If Vicki has 100 jelly beans then Bert would have 140. Bert would have to give 40 out of his 140 to Vicki or 40/100 -> 4/10 -> 2/5. Bert would have to give 2/5 of his jelly beans to Vicki.

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example:
2 + 3x + 4y = 7 is an expression.
3x + 4 = 3 is an expression.
3 + 4x - 5 is an expression.
We have,
-6x + 86 - 32x - 12 + 52x

n times 5 is equal to 24
word in equation and solve for variable
Answers
Step-by-step explanation: Remember that "times" mean multiply.
So reading the problem from left to right, we have n times 5,
that's n multiplied by 5 or 5n, is means equals, 24.
So we have 5n = 24.
We want to solve our equation for n so we want to get
n by itself on the left side of the equation.
Since n is being multiplied by 5, we need to divide both sides
of the equation by 5 and we have n = 24/5.
Don't be nervous to check your answer back in
the original equation even if it is a fraction.

Answer:
x = 60
Step-by-step explanation:
(x+22) + (x+6) + (x-28) = 180
x + 22 + x + 6 + x - 28 = 180
x + x + x + 22 + 6 - 28 = 180
3x = 180
x = 180/3
x = 60

Answer:
a = 1.8 to the nearest tenth.
Step-by-step explanation:
Remark
I don't think this case is ambiguous. It has only 1 solution, I think.
Step One
Find the top angle.
All triangles have 180 degrees.
15 + 105 + x = 180
120 + x = 180 Subtract 120 from both sides
x = 180 - 120
x = 60
Step Two: Find a
a/sin(60) = 2/Sin(105) Multiply both sides by sin(60)
a = 2 * Sin(60) / sin(105)
a = 2 * .8660 / 0.9659
a = 1.793

Sally collects stamps. Of all her stamps,
45% are from the United States. She has
90 stamps from the United States. How
many total stamps does she have?
Answers
Answer:
200 stamps
Step-by-step explanation:
Divide the 90 stamps by 45: The result is 2; it's equal to 1% of the total number of stamps. You then multiply it by 100 to get the full amount, which is 200 stamps.
90/.45=x/1.00
cross-multiply
.45x=90
x=200 stamps, dividing both sides by 0.45
+.45x+=+90+
+x+=+90%2F.45+

We all hate to bring change to a store. By using random numbers, we can eliminate the need for change and give the store and the customer a fair deal. Suppose you buy something for 20 cents. If the store generated a random number using the cash register (call the random number R), what rule could they use to decide whether you should pay $1 or $0 for the item
Answers
Answer:
Round off to closest value.
Step-by-step explanation:
In order to remove the requirement for change, every time the client buys a product for $0.20 the random number that lies between 0 and 1 would be produced also the same would be rounded to the closest value i.e. 0 or 1. In the case when 0 arise so the customer would not have to pay any amount but if 1 arise so the customer have to pay $1. So this type of method would remove the requirement for a minor change
