5x - 1 - 2x = 20. Solve for x.
Answer:
x = 7
Step-by-step explanation:
Given
5x - 1 - 2x = 20, that is
3x - 1 = 20 ( add 1 to both sides )
3x = 21 ( divide both sides by 3 )
x = 7
Step-by-step explanation:
5x-1-2x=20
3x-1=20
3x=20+1
3x=21
3x/3=21/3
x=7

Find the value of A in each cases:
- cosA=√3/2
Answer:
A = [tex]\frac{5\pi }{6}[/tex]
Step-by-step explanation:
Given that Cos A = [tex]-\frac{\sqrt{3} }{2}[/tex]
cos A = [tex]cos (\pi -\frac{\pi }{6} )[/tex]
A = [tex]\pi - \frac{\pi }{6}[/tex]
A = [tex]\frac{5\pi }{6}[/tex]

A car moves at a constant speed of 50 miles per hour. How many hours does it take the car to go 200 miles?
Answer:
4 hoursStep-by-step explanation:
Speed = 50 mphDistance = 200 milesUse formula:
distance = time x speedtime = distance / speedFind the value:
Time = 200 / 50 = 4 hoursRenee calculated 3/6 plus 2/4 and said the answer equaled 5/10. Amanda solved the same problem and said the answer equaled one whole. Whose answer is more reasonable?
Answer:
Amanda's
Step-by-step explanation:
Given :
3/6 + 2/4
The L. C. M of 6 and 4 = 12
(6 + 6) / 12
12 / 12
= 1
Renne's result = 5/10
Amanda's result = 1 whole
Hence, Amanda's result makes more sense.

Are there any balls of another colour in the bag? Give a reason for your
answer.
No because 0.4+0.15+0.06+0.14+0.25=1 and you cant get probability over 1

Anna saved $30 each month from babysitting for 2.75 years. She spent 75% of her savings on a computer.
How much money did Anna have left?
Answer:
45.00 is what she has left
Step-by-step explanation:
Anna has $275.5 left after buying computer.
What is the percentage?A percentage is a minimum number or ratio that is measured by a fraction of 100.
Given that Amount saved by Anna each month = $30
Time period = 2.75 years.
1 year = 12 months
2.75 years = 2.75 years x 12 = 33 months
The Amount saved in 33 months = 33 x 30 = $990
She spent 75% of her savings.
Amount spent = 75% of 990
Amount spent = 75% x 990
Amount spent = $742.5
Amount left = Savings - Amount spent
Amount left = 990- 742.5= $275.5
Hecne, Anna has $275.5 left after buying computer.

solve the system of equations
-3y+4x=13
-5y-6x=-67
Answer:
{x,y} = {67/16,-15/4}
Step-by-step explanation:
// Solve equation [2] for the variable y
[2] 2y = -8x + 26
[2] y = -4x + 13
// Plug this in for variable y in equation [1]
[1] 4x + 5•(-4x+13) = -2
[1] -16x = -67
// Solve equation [1] for the variable x
[1] 16x = 67
[1] x = 67/16
// By now we know this much :
x = 67/16
y = -4x+13
// Use the x value to solve for y
y = -4(67/16)+13 = -15/4

A large box of pencils contains 45 pencils. A small box of pencils contains 25 pencils.
How many more pencils are in 18 large boxes than in 18 small boxes?
180 pencils
360 pencils
450 pencils
810 pencils
Answer:
360 more pencils.
45x18=810 large pencils
25x18=450 small pencils
810-450+360
Step-by-step explanation:
</3 PureBeauty
Answer:
360
Step-by-step explanation:
So we do 45*18 for the large boxes which is 810 and 25*18 for the small boxes which is 450 so now we subtract 450 from 810 which is 360!
You flip a coin 100 times in the air and find that it lands on heads 65 times. Determine the theoretical and experimental probability of landing on heads. In your final answer, include all of your calculations.
Answer:
The experimental probability --> [tex]\frac{13}{20}[/tex]
The theoretical probability --> [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Key skills needed: Experimental vs theoretical probability, Fractions
1) The first thing you need to understand is experimental probability vs theoretical probability. (Do not include this in your work!!)
- Theoretical probability is based on simple reasoning
- Experimental probability is based on the results a person gets (so the experiment you did by flipping the coin)
2) Now with this, let's start solving:
Experimental probability ---> [tex]\frac{heads}{total}[/tex] --> You flipped the coin a total of 100 times, so the denominator would be 100. 65 of those would be heads so 65 is our numerator. So our experimental probability is --> [tex]\frac{65}{100}[/tex] --> Both have the factor of 5, so take the factor of 5 out of the numerator and denominator and you will get --> [tex]\frac{13}{20}[/tex] Now onto theoretical probability --> [tex]\frac{heads}{total}[/tex] --> There are 2 faces of a coin, 1 side is heads, and 1 side is tails --> The total number of faces is 2, so 2 is our denominator. There is only 1 side that is heads, so 1 is the numerator. This means --> Our theoretical probability is [tex]\frac{1}{2}[/tex]Hope you understood and have a nice day!! :D
Answer:
Experimental Probability: 65/100 We tested the probability 100 times, 65 of those times being heads. So %65 is our experimental probability (in percentage form) of flipping a coin and landing on heads. Simplified, 13/20 is our fraction.
Theoretical Probability: 50/100 or 1/2. There are two sides to a coin, and one is heads, so the theoretical probability is 1/2. In percentage form, the probability would be %50, or 50/100.
