Answer:
x=1
Step-by-step explanation:
3x+2(4x-4) = 3
3x+8x-8 = 3
11x-8 = 3
11x = 11
x = 11/11 = 1
The solution for x in the expression 3x + 2 (4x- 4) = 3 is,
⇒ x = 1
The given expression is,
⇒ 3x + 2 (4x- 4) = 3
We can simplify by apply distributive property and combine like term,
⇒ 3x + 2 (4x- 4) = 3
Apply distributive property,
⇒ 3x + 8x - 8 = 3
Combine like term,
⇒ 11x - 8 = 3
Add 8 both side,
⇒ 11x = 3 + 8
⇒ 11x = 11
Divide by 11,
⇒ x = 11 / 11
⇒ x = 1
Therefore, The solution for x in the expression 3x + 2 (4x- 4) = 3 is,
⇒ x = 1

a bag contains 6 white marbles and 4 black marbles. a marble is drawn without replacing the first one. what is the probability of drawing a white marble on the first draw, followed by a white marble on the second?
Answer:
30/90 or 1/3
Step-by-step explanation:
This is because we know that 6+4=10. So we know the odds of drawing a white marble first is 6/10. And if we draw one without replacing it. This makes the second time 5/9 for white and 4/9 for black. We can then multiply 6/10 by 5/9 and get 30/90 which is equal to 1/3.
Hope this helps!
Answer:
1/3
Step-by-step explanation:
P=6/10 ×5/9=30/90=1/3

Answer:
7⁴, seven to the fourth power, and 7×7×7×7 all are equivalent.
Answer:
7^4, 7 to the fourth power, and 7*7*7*7
Step-by-step explanation:
7^4, 7 to the fourth power, and 7*7*7*7 all equal 2,401.
4 to the seventh power equals 16,384.
And 28 does not equal 2,400.

Answer:
U'(-14, 8)Step-by-step explanation:
The transformations include:
T<-2,2>·D3This is a dilation by a scale factor of 3 and then translation 2 units left and 2 units up.
The transformation applied to the point U:
U(-4,2) → U'(-4*3 - 2, 2*3 + 2) = U'(-14, 8)Sarah and Jack go shopping Jack spends 20 percent of his money and Sarah spends 1/4 of her money how spends more?
2. Which equation can be used to determine what number, n, is 40% of 64?
0(40) (64) = n
040 : 64 =n
00.40(64) =n
O 64n = 0.40
Rewrite the percent as a decimal and multiply by 64
The answer is: 0.40(64) = n
Assume that when adults with smartphones are randomly selected, 44% use them in meetings or classes. If 8 adult smartphone users are randomly selected, find the probability that exactly 2 of them use their smartphones in meetings or classes.
Answer: The probability is 0.448
Step-by-step explanation:
First, 44% of adults use their smartphones in meetings or classes, then the probability that a random adult uses their smartphone on a meeting is:
p = 0.44
Then the probability that a random adult do not use it is:
q = 1 - 0.44 = 0.66
If 8 adult smartphone users are randomly selected, find the probability that exactly 2 of them use their smartphones in meetings or classes.
For a random (and fixed) case, the probability will be equal to the product of the individual probabilities for each person, this leads to:
P = (0.44)*(0.44)*(0.66)*(0.66)*(0.66)*(0.66)*(0.66)*(0.66)
P = (0.44)²*(0.66)⁶ = 0.016
And now we need to consider the different combinations. If we have C combinations, then the probability for the event will be C*P.
Remember that if we have N elements, the total number of different groups of K elements (from these N elements) is:
[tex]C(N,K) = \frac{N!}{(N - K)!*K!}[/tex]
In this case, we have N = 8, and K = 2
Then we get:
[tex]C(8, 2) = \frac{8!}{(8 - 2)!*2!} = \frac{8!}{6!*2!} = \frac{8*7}{2} = 4*7 = 28[/tex]
Then there are 28 different combinations.
This means that the probability is:
Probability = 28*P = 28*0.016 = 0.448
Probability = 0.448

PLEASE ANSWER ASAP FOR BRAINLEST!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
The circumference is 615.44.
The formula is
R = C/(pi)*2
( 2 is square)
( I can't find the pi symbol sorry)
So meaning in simple term, it would look like this
R = 615.44/2*(3.14)
615.44/6.28
then we divide which we will get 98

The 24/7 Truck Rental Company has been charging an initial rental fee of $29 plus $2.50 per hour for rental of their small trucks. After a change in pricing policy, the new fee will be $19 up front plus $3.25 per hour. After how many hours of renting the truck will the new plan be more expensive than the old plan
Answer:
14 hours
Step-by-step explanation:
Old plan :
Initial fee =. $29
Hourly fee = $2.50
New plan :
Initial fee = $19
Hourly fee = 3.25
Let number of hours = x
When new plan will be more expensive than old plan :
19 + 3.25x > 29 + 2.50x
3.25x - 2.50x > 29 - 19
0.75x > 10
x > 10 / 0.75
x > 13.3333
After 14 hours

The function pictured is a straight line, so it has a constant slope for all x values.
A function that has the same slope on its domain and when graphed is a straight line is a linear function.
You are choosing between two health clubs. Club A offers membership fee of $16 plus a monthly fee of $23. Club B offers membership for a fee of $20 plus a monthly fee of $21. After how many months will the total cost of each health club be the same? What will be the total cost for each club?
Answer:
After five months, the total cost would be the same.
Step-by-step explanation:
You'd have to write equations for the price per month for each club.
Let
x
equal the number of months of membership, and
y
equal the total cost.
Club A's is
y
=
25
x
+
40
and Club B's is
y
=
30
x
+
15
.
Because we know that the prices,
y
, would be equal, we can set the two equations equal to each other.
25
x
+
40
=
30
x
+
15
. We can now solve for
x
by isolating the variable.
25
x
+
25
=
30
x
