Answer:
Pretty sure it's B.
Step-by-step explanation:
The solution of given equation 10 ax + 11 ax = 12ax +45 is x = 5/a.
The correct answer is an option (B)
What is an equation?"It is a statement which consists of equal symbol between two mathematical expressions."
For given example,
We have been given an equation 10 ax + 11 ax = 12ax + 45
We need to solve given equation for x.
Assuming a ≠ 0,
⇒ 10 ax + 11 ax = 12ax +45
⇒ (10 + 11) ax = 12 ax + 45 ...............(Separate out common terms)
⇒ 21 ax = 12 ax + 45
⇒ 21 ax - 12 ax = 12ax + 45 -12 ax ...........(Subtract 12 ax from each side)
⇒ (21 - 12) ax = 45 ...............(Separate out common terms)
⇒ 9 ax = 45
⇒ 9ax/9a = 45/9a ..............(Divide both the sides by 9a)
⇒ x = 5/a
Therefore, the solution of given equation 10 ax + 11 ax = 12ax +45 is x = 5/a.
The correct answer is an option (B)

Answer:
a.x=4
b.x=4
c.(b)
Step-by-step explanation:
We are given that
[tex]9-x=5[/tex]
a. First we adding x on both sides we get
[tex]9-x+x=5+x[/tex]
[tex]9=5+x[/tex]
Now, subtract 5 on both sides we get
[tex]9-5=x[/tex]
[tex]x=4[/tex]
b.
We are subtracting 9 from both sides we get
[tex]9-9-x=5-9[/tex]

[tex]x=4[/tex]
We can solve equation both approach a and b
But I prefer (b) because in approach (b)
There are only 3 step in which we can get answer but in approach (a) we can get answer in 4 steps .

Shondra buys a bedroom suite on the in-stallment plan. She makes a down payment of $200 and monthly payments of $52 each for three years. What is her total cost
Answer:
$2072
Step-by-step explanation:
Note that:
1 year = 12 months
Hence:
1 year = 12 months
3 years = x months
Cross Multiply
x = 3 × 12
x = 36 months
She makes a down payment of $200 and monthly payments of $52 each for three years.
Her total cost is represented by the expression
= $200 + $52 × m
Where m = number of monthly payments.
$200 + $52 × 36
= $200 + $1872
= $ 2072

In the school chorus, 3 9 of the students are fourth graders. In simplest form, what fraction of the students in the school chorus are fourth graders?
Answer: 1 / 3
Step-by-step explanation:
3/9 of the students in the school choir are fourth graders.
To take a fraction to its simplest form, divide both of the numbers in the fraction by their highest common factor.
3 factors = 1 , 3
9 factors = 1, 3 , 9
Highest common factor = 3
Divide both numbers by 3

Two-sixth of the mangoes ina basket are good. If the total number of magoes in the basket is 42 how many mangoes are bad
Answer:
28 bad mangoes
Step-by-step explanation:
Two-sixth of the mangoes ina basket are good. If the total number of magoes in the basket is 42 how many mangoes are bad
Step 1
We find the amount of mangoes that are good
Two-sixth of the mangoes in a basket are good = 2/6
Total number of mangoes = 42
Hence:
2/6 × 42 mangoes
= 14 good mangoes
Step 2
Find the number of bad mangoes
This is calculated as:
Total number of mangoes - Good Mangoes
= 42 mangoes - 14 good mangoes
= 28 bad mangoes
Therefore, the number of bad mangoes = 28
what would be the solution for x inequality 47-4x<7
Answer:
x>10
Step-by-step explanation:
Think of this as an equation:
47-4x<7
Add 4x to both sides:
47<7+4x
Subtract 7 from both sides:
40<4x
Divide both sides by 4:
x>10
Answer:
x > 10
Step-by-step explanation:
Given
47 - 4x < 7 ( subtract 47 from both sides )
- 4x < - 40
Divide both sides by - 4, reversing the symbol as a result of dividing by a negative quantity.
x > 10
1. The current in a clothes washer is 15A when plugged into a 120V outlet. What is
the POWER of the washer? *
Answer:
Step-by-step explanation:
Power = Force × Velocity.
15*120=1800
To solve the problem we must know about resistance and power.
What is resistance?
Resistance is defined as the measurement that provides opposition to the current that travels through it.
It is given by the formula,
[tex]\rm Resistance = \dfrac{Voltage}{Current}[/tex]
The power of the washer is 1,800 watts.
Given to us
Current, I = 15 A
Voltage, V = 120V
Resistance Provided by the WasherUsing the formula of resistance to find the resistance,
[tex]\rm Resistance = \dfrac{Voltage}{Current}[/tex]
[tex]\rm Resistance = \dfrac{120\ V}{15\ A} = 8\ \Omega[/tex]
Thus, the resistance for the circuit will be 8 ohms.
Power of the washer[tex]\rm Power = (Current)^2 \times Resistance[/tex]
[tex]P = I^2 R\\\\P = (15)^2\times 8\\\\P = 1,800\ \rm watt[/tex]
Hence, the power of the washer is 1,800 watts.

Peter rolls 2 fair dice and adds the results from each. Work out the probability of getting a total less than 11.
Answer:
[tex]\frac{25}{36}[/tex]
Step-by-step explanation:
Since each dice has a total of 6 numbers, Peter can get a maximum roll of 5 on each dice before the total is 11 or more. Therefore, the probability of rolling a number less than or equal to 5 each roll is 5/6. Now to find the probability of rolling a 5 or less in both rolls together so that the total is less than 11 we need to multiply the probability of each separate roll together.
[tex]\frac{5}{6} * \frac{5}{6} = \frac{25}{36}[/tex]
Therefore the probability of the total being less than 11 is [tex]\frac{25}{36}[/tex]
Put the following lengths in ascending order, 900cm, 8.9m, 895cm, 9.1m, 12000mm, 0.0092km.
Answer: 8.9 m, 895 cm, 900 cm, 9.1 m, 0.0092 km, 12000 mm
===========================================================
Explanation:
To be able to compare these various measurements, all of them must be the same unit. Let's convert each measurement to meters. If the measurement is already in meters, then we'll move onto the next measurement.
Here are some useful conversion factors
1 m = 100 cm1 m = 1000 mm1 km = 1000 mWith those conversion factors in mind, we get the following conversions:
900 cm = (900 cm)*(1 m/100 cm) = (900/100) m = 9 m8.9 m = already in meters, moving on895 cm = 8.95 meters; divide by 100 to convert from cm to meters as shown above9.1 m = already in meters, moving on12000 mm = (12000 mm)*(1 m/1000 mm) = (12000/1000) m = 12 m0.0092 km = (0.0092 km)*(1000 m/1 km) = (0.0092*1000) m = 9.2 mHere is the summary of the conversions:
900 cm = 9 m8.9 m = 8.9 m895 cm = 8.95 m9.1 m = 9.1 m12000 mm = 12 m0.0092 km = 9.2 mThe original list of
{900cm, 8.9m, 895cm, 9.1m, 12000mm, 0.0092km}
becomes this equivalent list
{9 m, 8.9 m, 8.95 m, 9.1 m, 12 m, 9.2 m}
in that exact order.
After converting everything to meters, we can then sort the values from smallest to largest. Doing so gets us this sorted list of
{8.9 m, 8.95 m, 9 m, 9.1 m, 9.2 m, 12 m}
Then you convert back each measurement to its original form
{8.9 m, 895 cm, 900 cm, 9.1 m, 0.0092 km, 12000 mm}
which is the final answer.
