Answer:
x=1
Step-by-step explanation:
Step 1: Subtract 3x from both sides.
x+4−3x=3x+2−3x
−2x+4=2
Step 2: Subtract 4 from both sides.
−2x+4−4=2−4
−2x=−2
Step 3: Divide both sides by -2.
-2x/-2 = -2/-2

Gary Sanchez struck out 112 times in 350 at bats. What PERCENTAGE of his at-bats were strike outs?
Given :
Gary Sanchez struck out 112 times in 350 at bats.
To Find :
Percentage of his at-bats were strike outs.
Solution :
We know, percentage hits is given by :
[tex]Percentage = \dfrac{\text{Number of time bats were strike out}}{\text{Total number of bats}}\times 100 \ \%[/tex]
Putting all given values in above equation, we get :
[tex]Percentage = \dfrac{112}{350}\times 100\ \%\\\\Percentage = 32\ \%[/tex]
Hence, this is the required solution.
select the correct answer consider these functions f(x)=3x-7 g(x)=X +1/x-1 what is the value of f(g(3))
Answer:
Me and my massive brain, among other massive things of mine, believe it to be -1
Step-by-step explanation:
The value of the function F(g(x) will be equal to (7 / 2).
What is a function?A function is defined as the expression that set up the relationship between the dependent variable and independent variable.
Given functions are:-
f(x)=3x-7 g(x)= x +(1/x-1)The function F(g(x) is written as :-
F(g(x) = 3 [ x + ( 1 / ( x-1 )) -7 ]
F(g(x) = 3 [ (3 + (1/2) - 7 ]
F(g(x) = 3 (7 / 2 ) -7
F(g(x) = ( 21/2) - 7
F(g(x) = ( 21-14 ) ( 2 )
F(g(x) = ( 7/2 )
Therefore the value of the function F(g(x) will be equal to (7 / 2).

In AWXY, X = 1.2 cm, ZX=45° and Y=108°. Find the length of w, to the nearest 10th
Answer:
The length of w is 0.8 cm
Step-by-step explanation:
In Δ WXY
x is the opposite side to ∠X
w is the opposite side to ∠W
y is the opposite side to ∠Y
∵ m∠X = 45°
∵ m∠Y = 108
∵ The sum of the measures of the interior angle of a triangle is 180°
∴ 45 + 108 + m∠W = 180
→ Add the like terms in the left side
∵ 153 + m∠W = 180
→ Subtract 153 from both sides
∴ m∠W = 27°
Now we can use the sine rule to find the length of w
∵ [tex]\frac{w}{sin(W)}[/tex] = [tex]\frac{x}{sin(X)}[/tex] = [tex]\frac{y}{sin(Y)}[/tex]
→ Use the first 2 ratios to find w
∵ x = 1.2 cm
∵ [tex]\frac{w}{sin(27)}[/tex] = [tex]\frac{1.2}{sin(45)}[/tex]
→ By using cross multiplication
∴ w × sin(45) = 1.2 × sin(27)
∴ w sin(45) = 1.2 sin(27)
→ Divide both sides by sin(45)
∴ w = 0.7704474263
→ Round it to the nearest tenth
∴ w = 0.8 cm
∴ The length of w is 0.8 cm

Answer:
5
Step-by-step explanation:
Area of bedroom = 13 1/3 square yards
Area of bed = 2 2/3 square yards
Unit Rate = Area of bedroom / Area of bed
Unit Rate = (40 / 3 ÷ 8/3)
Unit Rate = 5

A plastics stock dropped 1 1/4 points every day of a 5-day business week. How many points did the stock drop that week?
Answer:
That will be 1/14 points
Step-by-step explanation:
==============================================
Work Shown:
1/4 = 0.25
1 & 1/4 = 1 + 1/4 = 1 + 0.25 = 1.25
The stock dropped by 1.25 points each day for 5 days
It dropped a total of 5*1.25 = 6.25 = 6 & 1/4 points.
------------
Alternative method:
5*(1 & 1/4) = 5*(1 + 1/4)
5*(1 & 1/4) = 5*1 + 5*(1/4)
5*(1 & 1/4) = 5 + 5/4
5*(1 & 1/4) = 5*(4/4) + 5/4
5*(1 & 1/4) = 20/4 + 5/4
5*(1 & 1/4) = (20+5)/4
5*(1 & 1/4) = 25/4
5*(1 & 1/4) = (24+1)/4
5*(1 & 1/4) = 24/4 + 1/4
5*(1 & 1/4) = 6 + 1/4
5*(1 & 1/4) = 6 & 1/4
We get the same answer as before.

Complete question is;
A group of biologists is surveying the mice population in a forest. The equation n=75⋅3t gives the total number of mice, n, t years since the survey began.
what does the number 3 mean in this situation.
1. the common difference
2. the total population
3. the common ratio
4. the slope
Answer:
3 is the common ratio
Step-by-step explanation:
We are given that the equation; n = 75⋅3^(t) gives the total number of mice, n, t years since the survey began.
Normally, formula when calculating population growth takes an exponential function;
n = n_o(e^(rt))
Or in this our case, it can be written as;
n = n_o((e^(r))^(t))
Comparing this with n = 75⋅3^(t), we can see that e^(r) = 3
Where r is the growth rate.
e is exponential constant.
Thus, we can say that 3 is the common ratio

Step-by-step explanation:
A hair stylist knows that 87% of her customers get a haircut and 40% get their hair colored on a regular basis. Of the customers who get their hair cut, 24% also get their hair colored. What is the probability that a randomly selected customer gets their hair cut and colored?
Answer:
0.35
Step-by-step explanation:
The probability that a customer gets a hair cut and also gets a hair colored is 0.2088
What is probability?Probability is a measure of the likelihood of an event occurring. The probability formula is defined as the possibility of an event happening is equal to the ratio of the number of favorable outcomes and the total number of outcomes. Probability of event to happen P(E) = Number of favorable outcomes/Total Number of outcomes.
Given here: The probability of customers getting a haircut is 87% and the probability that the customers that have a haircut also get their hair colored are 24%
Thus the conditional probability that a customer who has a hair cut also gets his hair colored is
P( haircut/hair colored )= 87%×24%
=0.87×0.24
=0.2088
Hence, The probability that a customer gets a hair cut and also gets a hair colored is 0.2088

What is the multiplicative identity of -12/13
A.-13/12
B.1
C.0
D12/13
Answer:
The number '1' is called the 'multiplicative identity' of a number '-12/13' because it does not change the number '-12/13' after getting multiplied by it.
Therefore, option (B) is true.
Step-by-step explanation:
We know that when a number let say 'n' get multiplied by '1', it remains unchanged.
i.e.
n × 1 = n1 × n = nThe number '1' is called the 'multiplicative identity' of a number 'n' because it does not change the number 'n' after getting multiplied by it.
Given the number
-12/13
Multiply the number '-12/13' by '1'.
i.e.
-12/13 × 1 = -12/13
1 × -12/13 = -12/13
Thus, the number '1' is called the 'multiplicative identity' of a number '-12/13' because it does not change the number '-12/13' after getting multiplied by it.
Therefore, option (B) is true.

: A coffee shop spends $408 for an order of 17 cases of paper cups. If the coffee shop adds 5 more cases of paper cups to the order, how much will the total cost be
Step-by-step explanation:
A case of paper cups costs $408 / 17 = $24.
5 more cases => 22 cases of paper cups total.
Hence the total cost will be 22 * $24 = $528.
Answer:
$528
Step-by-step explanation:
We find the unit rate of the cost per case.
$408 / 17 cases = $24/case
Each case costs $24.
Adding 5 cases to 17 cases, the order will be for 22 cases.
22 cases * $24/case = $528
