Multiply the polynomials (y −5)(2y+ 3)
Answer:
(-3 + -2y)(5 + -1y) = 0
Step-by-step explanation:
Simplifying
(y + -5)(2y + 3) = 0
Reorder the terms:
(-5 + y)(2y + 3) = 0
Reorder the terms:
(-5 + y)(3 + 2y) = 0
Multiply (-5 + y) * (3 + 2y)
(-5(3 + 2y) + y(3 + 2y)) = 0
((3 * -5 + 2y * -5) + y(3 + 2y)) = 0
((-15 + -10y) + y(3 + 2y)) = 0
(-15 + -10y + (3 * y + 2y * y)) = 0
(-15 + -10y + (3y + 2y2)) = 0
Combine like terms: -10y + 3y = -7y
(-15 + -7y + 2y2) = 0
Solving
-15 + -7y + 2y2 = 0
Solving for variable 'y'.
Factor a trinomial.
(-3 + -2y)(5 + -1y) = 0

Answer:
x=45
Step-by-step explanation:
First, we can add the two expressions and set them equal to 180.
3x+45=180
To isolate x, we can subtract 45 from each side, getting:
3x=135
Next, we can divide both sides by 3 to further isolate x. In the end, we get x=45.
a woman is 10 times as old as her daughter. In 8 years she will be 4 times as old as her daughter. How okd is her mother now?
Answer:
48 yr. old
Step-by-step explanation:
Assume daughter is 4 and mom is 10 times her age, so mom is 40.
10 (woman) * 4 (daughter's age) = 40 yr. old mom
Present day...
40 (yr old mom) + 8 (yrs later) = 48 yr. old mom today
4 (yr old daughter) + 8 (yrs later) = 12 yr. old daughter today
So, if mom is 4 times as her daughter's age today...
48 (yr. old mom) / 12 (yr. old daughter) = 4

A salesperson earns a commission of $322 for selling $2300 in merchandise.
Find the commission rate. Write your answer as a percentage.
The commission rate for the given amount will be 14%.
What is the percentage?According to its definition, a percentage is any number relative to 100. It is shown with the sign %. "Out of 100" is what the percentage means. Consider dividing any quantity or item into 100 identical bits.
To find the commission rate, we need to divide the commission earned by the amount of merchandise sold, and then express the result as a percentage.
The commission rate is given by:
Commission rate = (commission earned / amount of merchandise sold) x 100%
Substituting the given values, we get:
Commission rate = (322 / 2300) x 100%
Commission rate ≈ 0.14 x 100%
Commission rate ≈ 14%
Therefore, the commission rate is 14%.

Can someone tell me what is 3/20 x 100?
Answer:
15
Step-by-step explanation:
Answer:
300/20 = 15
Step-by-step explanation:
There are a number of ways to solve this problem, but I will show you the easiest way.
3/20 x 100/1 =
First, do 3 x 100. This gives you 300.
Next, do 20 x 1. This gives you 20.
So now, your answer is 300/20.
300 divided by 20 is 15, so this simplified version of 300/20 is 15!
300/20 = 15 (simplified)

Answer:
V =3.14 ( 2)^2 2.5 ft^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
Using 3.14 for pi
The diameter is 48 so the radius is 1/2 d = 1/2(48) =24inches and the height is 2.5 ft
We need to have the same units on the radius as the height
24 inches = 2 ft
V =3.14 ( 2)^2 2.5 ft^3
At a particular fast food restaurant, tacos cost $1.29 and
burritos cost $2.19. Michael spent a total of $42.93 at the
restaurant to buy food for a party. If he purchased half as
many burritos as tacos, how many tacos did he buy?
Answer:
Michael bought 18 tacos and 9 burritos.
Step-by-step explanation:
Since at a particular fast food restaurant, tacos cost $ 1.29 and burritos cost $ 2.19, and Michael spent a total of $ 42.93 at the restaurant to buy food for a party, if he purchased half as many burritos as tacos, to determine how many tacos did he buy, the following calculation must be performed:
1.29 x 20 + 2.19 x 10 = 47.7
1.29 x 16 + 2.19 x 8 = 38.16
1.29 x 18 + 2.19 x 9 = 42.93
So Michael bought 18 tacos and 9 burritos.

Answer:
a = 76
Step-by-step explanation:
a - 40 + a + 180 - (a + 36) = 180
a - 40 + a + 180 - a - 36 = 180
a + 104 = 180
a = 180 - 104
a = 76
Answer:
a = 76
Step-by-step explanation:
The remote angles theorem states that when one extends one side of a triangle, the sum of the two non-adjacent angles will equal the measure of the angle formed between the side of the triangle and the extension.
One can apply this theorem here by stating the following,
(a - 40) + (a) = (a + 36)
Simplify,
a - 40 + a = a + 36
2a - 40 = a + 36
Inverse operations,
2a - 40 = a + 36
-a -a
a - 40 = 36
+40 +40
a = 76
Which values are solutions to the inequality below? Check all that apply.
x² < 144
What are the two answers for this and how do I complete this problem?
9514 1404 393
Answer:
-12 < x < 12
Step-by-step explanation:
It helps to think about what this looks like on a graph.
y = x² describes a parabola that has its vertex at the origin and opens upward. You know that 12² = 144, so the value of x² will exceed 144 when the value of x is more than 12. You also know the parabola is symmetric about the y-axis, so the same will be true for values of x less than -12.
The one solution to the inequality is ...
-12 < x < 12
__
You can also go at this slightly differently--a way you might want to use for more complicated quadratic inequalities. Put the inequality in standard form, and factor it.
x² -144 < 0
(x +12)(x -12) < 0
Note that these factors are zero for x = -12 and for x = 12. The solution is the set of values of x where the sign of the product is negative.
The sign of the product of two numbers will be negative when one of them is negative and the other is positive. Since the zeros of this product are -12 and +12, the sign of the product will be different in the intervals (-∞, -12), (-12, 12), and (12, ∞). In the left-most of these intervals, both factors are negative, so the product is positive and the interval is not part of the solution set.
For the middle of these intervals, (-12, 12), the sign of (x+12) is positive and the sign of (x-12) is negative. The product will have a negative sign, so this interval is part of the solution set.
For the rightmost interval (12, ∞), both factors have positive signs, so the product is positive and the interval is not in the solution set.
Based on the analysis of the signs of the factors, we realize the solution to the inequality is the interval (-12, 12), or -12 < x < 12.
_____
The wording of your question suggests you are given a list of numbers and asked to identify those that satisfy the inequality. We don't see that list, so we can only tell you the set of numbers the solutions must be in.
Note that -12 or +12 are not solutions to this.
