Answer:
Step-by-step explanation:
1: Distribute or Divide (3) or Subtract (2)
3 (x + 5) + 2 = 3x + 15
2: Combine like terms
3x + 17 = 42.5 + 5
3: Subtract/Add
3x = 42.5 - 17 + 5
4: Divide/Multiply (If divide in first step, this one is skipped.)
x = 30.5 / 3
5: Solve
x = 10.166...

Answer:
x=-6 if y=8
Step-by-step explanation:
First, plug in 8 for y then solve:
2x+3(8)=12
2x+24=12
Next, subtract 24 from each side:
2x+24=12
2x-24=-24
2x=-12
x=-6

What is a ratio defined?The quantity, amount, or size link between two or more things: proportionRatios are used to compare two numbers by dividing them. If you want to compare one data point (A) to another (B), your formula would be A/B. This signifies that you are dividing data A by data B. If A is five and B is ten, your ratio will be 5/10.A ratio indicates the number of times one number contains another. For example, if a dish of fruit contains eight oranges and six lemons, the orange-to-lemon ratio is eight to six (that is, 8:6, which is equivalent to the ratio 4:3).a line segment on a coordinate plane has a slope of 1 and the end points at (1,a) and (9,b).

Which line is perpendicular to the line shown on the graph Map testing
Answer:
Step-by-step explanation:
Since the graph with the line isn't provided, I can only tell/show you how to find the perpendicular line.
When two lines a perpendicular, they can have different y-intercepts. But the slope of line will change to it's reciprocal.
So if you have a line that is y = 2x + 7 the perpendicular line would be,
y = -1/2 x + 7
A customer paid $53.00 for a jacket after a 6 percent sales tax was added. What was the price of the jacket before the sales tax was added?
Show work
Answer:
$50.00
Step-by-step explanation:
Answer:
The correct answer is: 49.82
Step-by-step explanation:
First, you have to turn 6% into a decimal.
6%=0.06 (6/100)
Then, you multiply 6% by $53.00
0.06*53=3.18
Finally, you subtract the sales tax ($3.18) from the total paid ($53.00)
53-3.18=49.82

if the original quantity is 20 and the new quantity is 18, what is the percent decrease?
Answer:
The answer is 10%
Step-by-step explanation:
The percentage decrease for the quantity change from 20 to 18 will be 10%.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that the original quantity is 20 and the new quantity is 18. The percentage decrease will be calculated as,
Percentage decrease = ( Original - decreased ) / original
Percentage decrease = ( 20 - 18 ) / 20
Percentage decrease = 2 / 20
Percentage decrease = 0.1
Percentage decrease = 0.1 x 100
Percentage decrease = 10%
Therefore, the percentage decrease for the quantity change from 20 to 18 will be 10%.

The numbers of ancestors in different generations of a male honey be follow a fibonacci sequence In 5 generations email honey bee has 8 relatives and 6 generations it has 13 oz and in 7 generations it has 21 relatives how many relatives does it have an 8 and 9 generations?
Answer:
8th generation: 34 relatives
9th generation: 55 relatives
Step-by-step explanation:
Fibonacci sequence is a sequence that is in such a manner that each number will be the sum of the two preceding ones.
Thus, to get how many relatives in the 8th generation, we will need to add the number of relatives in both the 6th and 7th generation.
We are given number of relatives in the 6th and 7th generation as 13 and 21 relatives respectively.
Thus;
No. of relatives in 8th generation = 13 + 21 = 34 relatives
Similarly;
No. of relatives in 9th generation is = no. in 7th generation + no. in 8th generation = 21 + 34 = 55 relatives

In the figure at the right, if PQ is perpendicular to QR,
then a + b + c + d =?
A) 180°
B) 225°
C) 270°
D) 360°
The correct answer is 270°
a + b + c + d = 270°
Given,
In the figure at the right, if PQ is perpendicular to QR.
We need to find a + b + c + d.
What is the sum of the angles in a right triangle?The sum of the angles in a right triangle must be 180 degrees.
We have,
In right-triangle PQR
PQ is perpendicular to QR.
So,
∠PQR = 90 degrees.
∠QPR = ∠QRP = 45 degrees.
We see that,
QS is perpendicular to PR
So,
∠QSP = b = 90 degrees
∠QSR = c = 90 degrees
Now,
From right-triangle QSP and right-triangle QSR.
We have,
QSP = b = 90 degrees
QPS = a = 45 degrees
QSR = c = 90 degrees
QRS = d = 45 degrees
Find a + b + c + d.
= 45 + 90 + 90 + 45
= 270 degrees
Thus the correct answer is 270°
a + b + c + d = 270°

Firefighters just arrived at the Farquand building with a rescue truck. Mr. Farquand is stuck on a window ledge 44 feet directly above the top of the truck. The base of the ladder is a horizontal distance of 33 feet away from the building. Using the Pythagorean Theorem, determine how long the ladder must extend to reach Mr. Farquand.
Answer:
Step-by-step explanation:
The ladder must extend to a length of 55 feet in order to reach Mr. Farquand on the window ledge.
In this scenario, the height of the building (opposite side) is 44 feet, and the horizontal distance from the base of the ladder to the building (adjacent side) is 33 feet.
Using the Pythagorean theorem, we can calculate the length of the ladder (hypotenuse) as follows:
Ladder length² = Height² + Distance²
Ladder length² = 44² + 33²
Ladder length² = 1936 + 1089
Ladder length² = 3025
Ladder length = √3025
Ladder length = 55 feet
Therefore, the ladder must extend to a length of 55 feet in order to reach Mr. Farquand on the window ledge.

The volumes of two similar solids are 729 m^3 and 125m^3. The surface area of a larger solid is 324 m^3. What is the surface area of the smaller solid
Answer:
100 m^2
Step-by-step explanation:
The scale factor of the volume of solids is the cube of the scale factor of linear dimensions.
The scale factor of the area of solids is the square of the scale factor of the linear dimensions.
Volume scale factor:
125/729 = (5/9)^3
Linear scale factor:
5/9
Area scale factor:
(5/9)^2 = 25/81
Proportion to find the area of the smaller one:
Let the area of the smaller one equal x.
25/81 = x/324
81x = 25 * 324
Divide both sides by 81
x = 25 * 4
x = 100
Answer: 100 m^2
