Answer:
1. 3 + x/3 = 9
2. 10 + 1/2x = 15
3. -3 + x/7 = -2
Step-by-step explanation:
What will be the result of substituting 2 for x in both expressions below?
1/2 x + 4
x + 6 - 1/2 x minus 2
Both expressions equal 5 when substituting 2 for x because the expressions are equivalent.
Both expressions equal 6 when substituting 2 for x because the expressions are equivalent.
One expression equals 5 when substituting 2 for x, and the other equals 2 because the expressions are not equivalent.
One expression equals 6 when substituting 2 for x, and the other equals 2 because the expressions are not equivalent.
Answer:pretty sure the answer is A
Step-by-step explanation:
1/2(2) + 4 = 1 + 4 = 5
2 + 6 - 1/2(2) -2 = 8 - 1 - 2 = 5

Find the reasons to prove the problem
cam hits the bullseye in 8 darts out of 15 throws. what is the experimental probability that came next throws will hit the bullseye?
Answer:
A darts player practices throwing a dart at the bull’s eye on a dart board. Her probability of hitting the bull’s eye for each throw is 0.2.
(a) Find the probability that she is successful for the first time on the third throw:
The number F of unsuccessful throws till the first bull’s eye follows a geometric
distribution with probability of success q = 0.2 and probability of failure p = 0.8.
If the first bull’s eye is on the third throw, there must be two failures:
P(F = 2) = p
2
q = (0.8)2
(0.2) = 0.128.
(b) Find the probability that she will have at least three failures before her first
success.
We want the probability of F ≥ 3. This can be found in two ways:
P(F ≥ 3) = P(F = 3) + P(F = 4) + P(F = 5) + P(F = 6) + . . .
= p
3
q + p
4
q + p
5
q + p
6
q + . . . (geometric series with ratio p)
=
p
3
q
1 − p
=
(0.8)3
(0.2)
1 − 0.8
= (0.8)3 = 0.512.
Alternatively,
P(F ≥ 3) = 1 − (P(F = 0) + P(F = 1) + P(F = 2))
= 1 − (q + pq + p
2
q)
= 1 − (0.2)(1 + 0.8 + (0.8)2
)
= 1 − 0.488 = 0.512.
(c) How many throws on average will fail before she hits bull’s eye?
Since p = 0.8 and q = 0.2, the expected number of failures before the first success
is
E[F] = p
q
=
0.8
0.2
= 4.
An equation is shown below: 4c + 2(x-3) = 4x + 2x - 11 Part A: solve the equation and write the number of solutions. Show all the steps. Part B: Name one property you used to solve this equation.
Part A: first multiply 2 by x and -3 → combine all like terms → Add 6 on both sides → subtract 6x from both sides.
Your final answer should be -5
step by step: 4x + 2(x-3) = 4x + 2x - 11
4x +2x -6 = 4x + 2x - 11
6x -6 = 6x - 11
6x = 6x -11 +6
6x = 6x -5
6x-6x= -5
0 = -5
Part B: Add all like terms.

The human skeleton can be divided into two systems. The axial system has 80 bones. It consists of the skull, spine, and ribs. The appendicular system has 126 bones. It consists of the shoulders, pelvis, and limbs. What fraction of the body’s bones are in the axial system? Give your answer in the simplest form. PLEASE HELP
The fraction of the body’s bones in the axial system is 40/103.
Given that, the axial system has 80 bones and the appendicular system has 126 bones.
What is the fraction?In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.
Total number of bones in the human skeleton system
= 206
Fraction of bones in the axial system
= 80/206
= 40/103
Hence, the fraction of the body’s bones in the axial system is 40/103.

Step-by-step explanation:
Three salesmen work for the same company, selling the same product. And, although they are all gold on
a weekly basis, each salesman earns his paycheck differently
Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of
$1,300
Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits
on the amount of commission he can earn
Salesman C does not corn any commission. His weekly salary is $900,
Suppose Salesmen A and B have the same number of sales and earn the same amount in Week of this
month. How many sales must they both have had?
Answer:
none of them are proportional. proportional would mean that they would earn 10 times as much if they sold 10 times as much.
A = 65 s maximum of 1300
B = 300 + 40 s
C = 900

A store sells two kinds of candles,scented candles and unscented candles. The candles burn at different rates which kind of candle burns more in one hour? How much more per hour? The scented one burns 1/8inch an hour 1/4 hour and the unscented one burns 1/9 inch in 1/3 hour. SHOW WORK!!!!
Step-by-step explanation:
The first thing we must observe is that the hourly rate for each candle is:
scented candles:
(1/12) / (20/60)
Simplifying:
= (1/12) / (10/30)
= (1/12) / (5/15)
= (1/12) / (1/3)
= (3/12)
= (1/4) inches / hour
Unscented candles:
(1/6) / (30/60)
Simplifying:
= (1/6) / (15/30)
= (1/6) / (3/6)
= (1/6) / (1/2)
= (2/6)
= (1/3) inches / hour
Answer:
The unscented candles burn faster at a rate of:
(1/3) inches / hour.
Answer:

The exponents are solved and the number of times larger is n = 290,476,190,476.19
What is Exponential Form?The exponential form is an easier way of writing repeated multiplication involving base and exponents. It has a base and a power
The exponential form of a number is a way of representing a number using exponents, where the base is typically a number greater than 1.
It is often used in mathematics and science to represent large or small numbers more efficiently. It can also be used to simplify certain mathematical operations, such as multiplication and division, by using the properties of exponents.
Given data ,
Let the first number be p = 6.1 x 10⁷
Let the second number be q = 2.1 x 10⁻⁴
And , the exponents are divided and the value of n is
To estimate how many times larger 6.1 x 10⁷ is than 2.1 x 10⁻⁴, we can divide the two numbers and then round the result to the nearest whole number.
n = 6.1 x 10⁷ / 2.1 x 10⁻⁴ ≈ 290,476,190,476.19
Rounding this to the nearest whole number gives us:
n ≈ 290,476,190,476
Hence , we can estimate that 6.1 x 10⁷ is approximately 290,476,190,476 times larger than 2.1 x 10⁻⁴

1 inch represents 1/3 foot
Step-by-step explanation:
Scale = 51 inches
Actual = 17 feet or 204 inches
Use a ratio to compare the two 204:51 or 204/51 = 4
This means that the actual size is 4 times the scale size
Take 1 inch in the scaled size and multiply it by 4 to get the actual size to get 4 inches
4 inches = 1/3 foot, therefore 1 inch represents 1/3 foot
