Answer: 15/7
Step-by-step explanation: Simplify 6/2 to 3
8x-3=x+12
Add 3 to both sides
8x=x+15
Subtract x from both sides
7x=15
Divide both sides by 7
x=15/7
Answer:
x = 2.14
Step-by-step explanation:
8x - 3 = x + 12 (6/2 = 3)
7x - 3 = 12 (subtracted 1x from both sides)
7x = 15 (added 3 to both sides)
x = 2.14 (divided 15 by 7)

How much would you have to deposit today to have an accumulated amount of $20,000 in 20 years if yearly interest is 4.75% compounded continuously?
Answer: $7734.82
Step-by-step explanation:
You would use the equation F=Pe^rt because the interest is continuous.
What we know:
F= 2000
r= 4.75%
t= 20
Plug in the information to the equation: 2000=Pe^.0475*20.
Because we need P by itself, you would divide the e^rt on both sides so then they cancel out and you get 2000/e^.0475*20 = 7734.820469.
Rounding it to the hundredth place, you’ll get $7734.82
Hope that this helps :)

I say this mainly because if you buy two 6 packs of soda that will add up to 4 dollars and 8 cents which is cheaper than the 12 pack.
Triangle Sum- Therorem
If m∠ABC=7x-2 and ∠CDE=5x+16 are congruent, find m∠ABC?
Answer: m∠ABC = 61°
Step-by-step explanation: Since angles are congruent, make the equation
7x-2 = 5x + 16
7x-5x = 16 +2
2x = 19
x = 9
Substitute 9 for x
7(9) -2 = m∠ABC . and 5(9) + 16 = m∠CDE
63-2 = 61° = m∠ABC 45 + 16 = 61 True!
Q2 - Expected and observed frequencies
It is beleived that a 6-sided dice is biased so that:
If you roll the dice 360 times, what is the expected frequency for each score?
P(1) = 0.1 P(2) = 0.15 P(3)= 0.05 P(4) = 0.2
P(5) = 0.2 P(6) = 0.3
Score | 1 2 3 4 5 6
expect| ***6 boxes are here**
-ed |
frenqu|
-ency |
—————————
In fact the observed frequencies are as follows:
Score 1. 2. 3. 4. 5. 6
Observed. 39 59. 17. 71. 78. 96
frequency
What does this tell you?
1. the model seems reasonable
2. the model is wrong
3. you need to buy a new dice
Answer:
1 and 3. For 1, look below. You really do need to buy new dice.
Step-by-step explanation:
For the sake of simplicity let's turn all these decimals to ratios.
Divide all by 0.05, then let's add the observed frequency on top. Then we can divide the big number by the small one.
2 - 39: 20
3 - 59: 20
1 - 17: 17
4 - 71: 18
4 - 78: 20
6 - 90: 15
It's up to you to decide if the model is reasonable. To me, it is.

A man has 27 coins in his pocket, all of which are dimes and quarters. If the total value of his change is 525 cents, how many dimes and how many quarters does he have?
Your answer is
number of dimes equals=
number of quarters equals=
17(quarters)
10(dimes)
Step-by-step explanation:Hi there !
dimes = 0.1$ = 10c
quarters = 0.25$ = 25c
d + q = 27 => d = 27 - q
10d + 25q = 525
replace d
10(27 - q) + 25q = 525
270 - 10q + 25q = 525
25q - 10q = 525 - 270
15q = 255
q = 255 : 15
q = 17(quarters)
d = 27 - q
= 27 - 17
d = 10(dimes)

Marla is solving the equation shown below. Two of her friends, Peter and
Uma present equations that they claim are equivalent to Marla's. Which
statement is correct about their equations.
=
Marld's equation :
[(x + 5) + x ] + 8 15
Peter's equation : (x + (5 + x)] + 8
+ 8 = 15
Uma's Equation : (x + 5) + (x + 8]
= 15
Only Peter's equation is equivalent to Marla's
Only Uma's equation is equivalent to Marla's
Both Peter and Uma have written equations that are equivalent to Marla's.
Neither Peter nor Uma's equations are equivalent to Marla's.
Answer:
2(2x +4y) +(3x -y) = 2(10) +(8)
.. 7x +7y = 28
Marla has incorrectly calculated the constant as 12. It should be 28.

The function f(x) = 4x + 10 models the amount of money Francis makes when babysitting for x hours. How much money will he make
for 2 hours of babysitting work?
18
-3
-2
2
Answer:
18
Step-by-step explanation:
You plug in 2 hours as your x value. You get 4(2) + 10 = 18.
The amount of money he will make for 2 hours of babysitting work is 18 dollars.
What is a function?The function is a type of relation, or rule, that maps one input to a specific single output.
We have been given that the function f(x) = 4x + 10 models the amount of money Francis makes when babysitting for x hours.
Plug in 2 hours as x value.
f(x) = 4x + 10
f(2) = 4(2) + 10
f(2) = 8 + 10
f(2) = 18
Hence, he will make 18 dollars for 2 hours of babysitting work

Step-by-step explanation:
so yu do 18+18 and yu get 36 and then you do 43+3 vause that is how muvk the lockers cost
Answer:
$2
Step-by-step explanation:
Fees = $18
Locker fee =$d
Total cost for 2 people,including locker for 2 people
=$40
2($18 + d) = $40
$36 +2d = $40
2d = $4
d = $2

Fees for one people =$18
Two people =$18 × 2 = $36
Total cost for 2 people - locker for 2 people = $40 - $ 2($2) = $40 - $4 = $36
