Answer: + or - in between the 3x and 6? Can be either 7 or 3
Step-by-step explanation:
3x+6=15.
Subtract '6' on both sides.
3x=9.
Divide by '3'.
x=3
3x-6=15.
Add '-6' on both sides.
3x=21
Divide by '3'.
x=7

mary robertson sells tires at a large car service center she earns 10 commission on the first $1000 15 on the next $2000 and 20 on sales of more than $3000 last
Her total commission was $560.
As 10% of the first $1,000, 15% of the next $2,000, and 20% of sales beyond $3,000 are commissions that she receives. She sold $3,400 worth of tires last week.
What does "total commission" mean?
The commission serves as a benefit or an inducement for the worker to close agreements so that the business can increase revenue and profits. The total commission is calculated by multiplying the total sales by the commission percentage.
After dividing the outcome by 100, multiply the sale price by the commission percentage. Perform the subsequent calculation: Each blue gadget costs $70. The salesman receives a 14% commission on each sale, or $9.80.
The percentage or fixed payment connected to a specific number of sales is referred to as a "commission rate." A commission, for instance, can be $30 or 6% of sales.
It is therefore $560.

From 2018 to 2010, the total number of passengers passing through Changi Airport increased by 4% In 2019, the total number was 68 280 000. Calculate the number of passengers passing through Changi Airport in 2018.
Leave your answer correct to the nearest whole number.
Step-by-step explanation:
I guess this means from 2018 to 2019 (and not to 2010).
so, compared to 2018 the numbers of 2019 were 104% (100% of 2018 plus 4% increase).
104% = 68,280,000
100% = 104%/1.04 = 68,280,000/1.04 =
= 65,653,846.15 ≈ 65,653,846
the number of passengers in 2018 were about

17h - 7 = 10h - 2 + 7h
Our initial equation:
17h - 7 = 10h - 2 + 7h
I want to get variables ("h") on one side, and numbers on the other, hence I will add 2 to both sides to shift numbers to the left side.
17h - 5 = 10h + 7h
Now I want to simplify the "h" on the right side.
17h - 5 = 17h
Now I will move the variable from the left to the right.
-5 = 0
17h - 17h is zero, think of h being equal to 1 if you don't get it.
-5 = 0 is a false inequality, there are no solutions.

The value of the variable x is 5 and the lengths of PL and LQ are 9 and 48, respectively.
How to find the value of a variable and the length of the line segments behind that variable
In this problem we find a line segment generated by points P and Q and in which a point L divides the line segment PQ in two sections: PL and LQ. In accordance with the statement, we have the following equations describing the geometric system:
PQ = PL + LQ
PQ = PL + LQ
57 = (2 · x - 1) + (9 · x + 3)
Now we proceed to clear the variable x with the resulting equation:
57 = 11 · x + 2
55 = 11 · x
x = 5
And finally we find the length of each line segment:
PL = 2 · 5 - 1
PL = 9
LQ = 9 · 5 + 3
LQ = 48
The value of the variable x is 5 and the lengths of PL and LQ are 9 and 48, respectively.

Jill records the temperature outside every hour for 4 hours. She finds that the temperature dropped by the same amount each hour. After 4 hours, she finds that the temperature dropped a total of 20∘F. She writes this number sentence.
(−20)÷4=−5
What does the number sentence mean?
1. The total drop in temperature, −20∘F, divided by 4 hours equals −5∘F per hour. The temperature dropped 5∘F each hour.
2. The total number of drops, 20, divided by 4 hours equals 5 times per hour. The temperature dropped 5 times per hour.
3. The total drop in temperature, −20∘F, divided by 4∘F in the first hour, equals −5 drops. The temperature dropped 5 times.
4. The total number of hours, 20, divided by 4∘F equals 5 hours. The temperature dropped once every 5 hours.
The total drop in temperature, −20∘F, divided by 4 hours equals −5∘F per hour. The temperature dropped 5∘F each hour. (option 1)
What does the sentence mean?Division is the process of grouping a number into equal parts using another number. The sign used to denote division is ÷. Division is one of the basic mathematical operation.
If the total drop in temperature over 4 hours is −20∘F, in order to determine the temperature drop each hour, divide −20∘F by 4.

Find the missing angles x and y vertical/adjacent angles
Answer: x = 49 degrees, y = 41 degrees
Step-by-step explanation:
Using supplementary angles, we know that x + y + 90 degrees = 180 degrees.
Using complimentary angles, we know that x + 41 degrees = 90 degrees, and x + y = 90 degrees.
Solving first for x,
x + 41 degrees = 90 degrees
x = 90 - 41 degrees
x = 49 degrees
Solving for y,
x + y = 90
Substituting 49 degrees in for x,
y + 49 degrees = 90 degrees
y = 90 - 49 degrees
y = 41 degrees

Based on your computations from part I of this exercise, determine which one of the following rules holds for matrices. select all that applies. group of answer choices:
a) A( B + C ) = AB + AC
b) A( B + C ) = BA + CA
c) (A + B)² = A² + 2 AB + B²
d) (AB)² = A²B²
e) (A - B)( A + B ) = A² - B²
The option that is correct is option (a) A( B + C ) = AB + AC.
We know that distributive property holds for all the matrices.
So, we get that:
A( B + C ) = AB + AC
We also know that commutative property does not hold for matrices.
So, we get that:
A( B + C ) = AB + AC ≠ BA + CA
A( B + C ) ≠ BA + CA
(A + B)² = A² + BA + AB + B²
(A + B)² ≠ A² + 2 AB + B² (as AB ≠ BA)
(AB)² = ABAB ≠ A²B²
(A - B)( A + B ) = A² - BA + AB + B² ≠ A² - B²
Therefore, we get that only option (a) A( B + C ) = AB + AC is the correct option.

What is the maximum value for y in the following function?
Answer:
D. 8
Step-by-step explanation:
well, let's look at the different parts of the functional expression :
the maximum of 5 is 5, of course.
the maximum of 3 is 3.
the maximum of sin(2x) is the maximum of any sine = 1.
sin(2x) only changes the frequency of the sine wave (the max and min values appear twice as often than for sin(x)), but does not have an impact on the amplitude, which defines the max. and min. values.
sin(2x) is NOT the same as 2×sin(x).
sin(2x) still "waves" between +1 and -1.
so, the total maximum is
5 × 1 + 3 = 8

Two riders leg length are 80 centimeters and 85 centimeters. To the nearest tenth of a centimeter, how much taller should the taller mountain bike frame be?
The taller mountain bike frame should be 3.4cm taller.
What should be the difference in the frames?The equation that can be used to determine the ideal height of the mountain bike frame is:
Mountain bike frame : (2/3 x length of the bike rider's leg) - 10
Mountain bike frame when leg length is 80cm: (2/3 x 80) - 10 =53.3 - 10 = 43.3 cm
Mountain bike frame when leg length is 85cm: (2/3 x 85) - 10 = 56.7 - 10 = 46.7cm
