The sum of three numbers is 107 . The first number is 8 less than the third . The second number is 3 times the third . What are the numbers ?
Answer:
(x - 8) + 3x + x = 107
x - 8 + 3x + x = 107
5x - 8 = 107
5x = 115
x = 23, SO...
The first number is 23-8, which is 15
The second number is 3 x 23, which is 69
The third number is 23
15 + 69 + 23 = 107 CHECK!

Edward deposited $8,500 into a savings account 5 years ago. The simple interest rate is 3%. How
much money did Edward earn in interest?
Answer:
1275
Step-by-step explanation:Step-by-step explanation:
For us to get the Simple interest, we have to use the formula:
= PRT
= Principal × Rate × Time
= $8500 × 5% × 3
= $8500 × 5/100 × 3
= $8500 × 0.05 × 3
= $1275

Answer:
MN = 25
Step-by-step explanation:
If LN=45, then the addition of both quantities will be 45.
LN = 3x + 2 + x + 19
3x + 2 + x + 19 = 45
4x + 21 = 45
4x = 45 - 21 = 24
x = 6
Now that we found the value of "x", we can find the lenght of MN
MN = x + 19
MN = 6 + 19
MN = 25
Hope it was helpful ;)
Answer: MN = 25
Step-by-step explanation:
Since the length is already given we just add the equations equal to it.
45 = 3x + 2 + x + 19 Combine like terms
45 = 4x + 21 Subtract 21 from both sides
24 = 4x Divide by 4
x = 6
Now we plug x into the equation needed.
X + 19
6 + 19 = 25

OB. 6
C. 673
D.

This is a special kind of right triangle, called a 30-60-90 triangle.
Across from the 30 degree angle, the side is equal to x. Across from the 60 degree angle, the side is equal to x[tex]\sqrt{3}[/tex]. And across from the 90 degree angle, the side is equal to 2x.
Using what we know about 30-60-90 triangles, lets first solve for x. We know that the hypotenuse, given, is equal to 6.
2x = 6
x = 3
Then, we are looking for the side opposite of the 60 degree angle. So its value is x[tex]\sqrt{3}[/tex].
x = 3
3 * [tex]\sqrt{3}[/tex] = 3 [tex]\sqrt{3}[/tex]
y = 3[tex]\sqrt{3}[/tex] (option D)
Hope this helps!! :)
The value of y for the given triangle will be 3√3, hence option (D) will be correct.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
Right angle triangles are triangles in which one angle is 90°.
The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.
Given a right-angle triangle
Let the side opposite to 30° is perpendicular and the remaining y will be base.
By trigonometric relation
cosx = base/hypotenuse
cos30° = y/6
y = 6 × cos30° ⇒ y = 6 × √3/2
y = 3√3 hence the value of the hypotenuse or y will be 3√3.

Read the excerpt from "Bone Detective."
Diane stood in front of a mirror and stuck out her tongue. It looked like a rosy pink welcome mat to her delicate insides. Her usual rubber mold formula was out of the question—too toxic. She wondered, What is safe to swallow, fast and easy to apply, and hardens quickly into a firm mold?
One of her horse-riding pals, a veterinarian named Mary Wright, had the answer: alginate. Mary told Diane that alginate was a pink gummy material used to make molds of teeth. If it was safe for pets, it should be safe for a tiger.
And people, too, Diane thought.
At her lab she mixed the alginate powder with water to form a paste. Standing in front of a mirror, she scooped up a blob and spread it on her tongue. She pressed it down with her fingers to get out any air bubbles. Not bad, she thought. Tastes just like spearmint. She decided to make an extra-thick mold to make it easier to peel off. So, she added another gloopy blog—and another.
With her thickened tongue hanging out, Diane padded around the lab doing odds and ends while the material set. After about 10 minutes, she peeled off the alginate slowly and carefully. It was fragile—bendable and easy to tear—but it made an excellent impression of her tongue.
Which action in the excerpt illustrates that Diane is dedicated to her work?
She makes a mold of her own tongue.
She performs odd jobs around the lab.
She stands in front of the mirror.
She goes horseback riding with a friend.
Answer:

Jackson, Christabelle and Janessa have $438. Jackson has 3 times as much money as Christabelle. Janessa has $263 more than Jackson. How much money does Jackson have?
Answer: Jackson has $75
Step-by-step explanation:
Step 1
Let the amount of money Christabelle has = x
Let the amount of money Jackson has = 3x
and the amount of money Janessa has= 3x+ 263
Such that the total money they all have which = $438 be expressed as
Christabelle's money +Jackson's money + Janessa's money= $438
x+ 3x+ 3x+ 263 = 438
Step 2 ---Solving
x+ 3x+ 3x+ 263=438
7x= 438-263
7x=175
x =175/7
x=25
Therefore,
Christabelle = $25
Jackson = 3x= 3 x25 = $75
Janessa= 3x+ 263= $75+263=$338

Original Price
Percent of Discount 25%
Sale Price $40
The original price is $53.33, as per linear equation.
What is a linear equation?"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, 'x' is a variable, 'A' is a coefficient and 'B' is constant."
Given, the percent of discount 25% = 0.25.
Sale price $40.
Let, the original price is x.
Therefore, [x - (x × 0.25)] = 40
⇒ (x - 0.25x) = 40
⇒ 0.75x = 40
⇒ x = (40/0.75)
⇒ x = 53.33
Therefore, the original price is $53.33.

Laura has two jobs to help pay for her weekly expenses.
• Laura can work at most 20 hours per week.
She needs to earn at least $120.
• Laura's dog-walking job pays $9.00 per hour.
• Laura washing cars pays $11.00 per hour.
Create the system of inequalities to model Laura's situation where x represents the hours she spends dog-walking
and y represents the hours she spends washing cars.
Answer:
x*$9.00 + y*$11.00 ≥ $120
x + y ≤ 20 hrs
Step-by-step explanation:
we have the variables:
x = hours she spends dog-walking
y = hours she spends washing cars.
We know that she wins $9.00 per hour of dog-waling, and she wins $11.00 per hour of washing cars, then the total amount of money she wins per hour is:
x*$9.00 + y*$11.00
And she needs to earn at least $120, then we have the inequality:
x*$9.00 + y*$11.00 ≥ $120
And we also know that she can work, at most, 20 hours per week, then:
x + y ≤ 20 hrs
Then the system of inequalities that represents this situation is:
x*$9.00 + y*$11.00 ≥ $120
x + y ≤ 20 hrs

A rectangular garden is to cover 416 square feet of area. If the width is 10
feet less than the length, find the dimensions of the garden.
Answer:
Length = 26 feet, Width = 16 feet
Step-by-step explanation:
Let the length be l.
Width b = l-10
The area of a rectangular garden, A = 416 feet²
We need to find the dimensions of the garden. The area of a rectangular shaped object is given by :
[tex]A=lb\\\\l(l-10)=416\\\\l^2-10l-416=0\\\\l=26\ ft,-16\ ft[/tex]
Neglecting the negative value, the length of the garden is 26 feet and the width is 12-10 = 16 feet.

In your own words explain how you would solve this two step equation for the variable x. 9x-7=-7
Answer:
Add 7 to both sides
Step-by-step explanation:
The equation has to be just x = y
There cannot be another number on the same side as the variable
Now that we did that, the equation is 9x = 0
x = 0
Well, that was easy lol
Answer:
Step-by-step explanation:
Add 7 to both sides
9x = 0
Then divide by 9 both sides to get x by itself
