Answer:
Answer: D. x/4 = 13
Step-by-step explanation:
Equations
Solve the following equation:
x - 12 = 40
Adding 12:
x = 52
Let's test each option to find which one of them has the same solution.
A. x/2 = 14
Multiplying by 2:
x = 28
B. x + 12 = 40
Subtracting 12:
x = 28
C. 12 - x = 40
Subtracting 12:
-x = 28
Multiplying by -1:
x = -28
D. x/4 = 13
Multiplying by 4:
x = 52
This last option is true.
Answer: D. x/4 = 13

An experiment involves studying the composition of genders of a set of triplets. What is the \nprobability that there are 2 boys and a girl in the set?
Answer:
37.5%
Step-by-step explanation:
The computation is shown below:
Here we assume that the 1st, 2nd and 3rd child be the triplet and it could be either a girl or boy
Now
B = Boy
G = Girl
The possible triplets are
(BBB) (BBG) (BGB) (BGG) (GBB) (GBG) (GGB) (GGG)
These are 8 triplets
Now find the sets that involves 2 boys and a girl
(BBG) (BGB) (GBB)
Now the probability is
P = 3 ÷ 8
= 37.5%

Find the domain and range of the exponential function h(x) = –343x.
Explain your findings.
As x decreases, does h increase or decrease? Explain.
As x increases, does h increase or decrease? Explain.
The function is supposed to be;
h(x) = -343^(x)
Answer:
The domain will be a set of real numbers while the range will be y ≤ 0 and on the interval (-∞, 1)
As x is increasing, h is decreasing and as x is decreasing, h is increasing
Step-by-step explanation:
We are given the function as;
h(x) = -343^(x)
The formula is;
y = a^(x) since it's symmetrical to the x-axis
However in this case;
y = -a^(x)
Now, the domain is y and the range is a set of values of x.
I've attached a graph of this function drawn on desmos.
From the graph we can see that The domain will be a set of real numbers while the range will be on the interval (-∞, 1)
For a value of x = 0,we have;
h(0) = -343^(0)
h(0) = -343
When we increase the value of x to 3,we have;
h(3) = -343^(3)
h(3) = -40353607
When we decrease the value of x to -3, we have;
h(-3) = -343^(-3)
h(-3) = 0.00000002478
Thus, we can conclude that;
As x is increasing, h is decreasing and as x is decreasing, h is increasing
Henry went clothes shopping and bought 3 pairs of shorts for $22.99 each, 2
shirts for $32.99 each and one pair of shoes for $54.99. What is the most
reasonable estimate of the total amount he spent on all the clothing?
A. $135
O B. $184
C. $190
D. $223
Answer:
$190
Step-by-step explanation:
22.99 times 3 = 66.97
32.99 times 2 = 65.98
one pair of shoes is 54.99.
66.97 + 65.98 + 54.99 = 187.94
187.94 is closer to 190

Evan earns money for doing chores. He earns $3 for putting away laundry and $4 for unloading the dishwasher. Evan wants to earn a total of $36. Let x represent the number of times Evan puts away the laundry and y represent the number of times he unloads the dishwasher. Write a linear equation for the situation and determine which ordered pair below would be a solution. a.(0,8) b.(4,6) c.(3,6) d.(1,12)
Answer:B(4,6)
Step-by-step explanation: ima pro at math
3*4=12+ 6*4=24
=36
The linear equation representing the situation is 3x + 4y = 36 and the coordinate (4, 6) represents the solution of this linear equation.
What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is Evan who earns money for doing chores. He earns $3 for putting away laundry and $4 for unloading the dishwasher.
Assume that [x] represent the number of times Evan puts away the laundry and [y] represent the number of times he unloads the dishwasher.
The total money Evan needs = $36.
We can write the linear equation representing the situation is as follows -
3x + 4y = 36
It can be seen that, the coordinate (4, 6) would be the solution of the linear equation as -
3 x 4 + 4 x 6 = 12 + 24 = 36
Therefore, the linear equation representing the situation is 3x + 4y = 36 and the coordinate (4, 6) represents the solution of this linear equation.

The Cheer Team is cooking for a breakfast fundraiser. They know that 22 pancakes can feed 8 people. They are wondering how many people they can serve with 220 pancakes (assuming everyone gets the same number of pancakes
Answer:
220 pancakes could feed 80 people.
Step-by-step explanation:
Since the Cheer Team is cooking for a fundraiser breakfast, and they know that 22 pancakes can feed 8 people, to determine the number of people that can be fed 220 pancakes it is necessary to perform the following calculation:
22 = 8
220 = X
(220 x 8) / 22 = X
1760/22 = X
80 = X
Therefore, 220 pancakes could feed 80 people.

3x 32 = 7x + 28
Answer:
x= 28 /89
Step-by-step explanation:
3x(32)=7x+28
Step 1: Simplify both sides of the equation.
96x=7x+28
Step 2: Subtract 7 from both sides.
96x 7x+28
−7 −7
89x=28
Step 3: Divide both sides by 89.
89x /89 = 28 /89

Ben bought a bag of potatoes that weighed 2.25 pounds. He also bought 2 boxes of raisins that weighed 0.375 pound each and 2 bags of apples that weighed 1.5 pounds each. Ben carried all items except for one bag of apples, which his brother carried. How many total pounds did Ben carry?
A.
1.5 pounds
B.
4.125 pounds
C.
4.5 pounds
D.
5.625 pounds
Answer:
The correct answer is C. 4.5 pounds.
Step-by-step explanation:
Since Ben bought a bag of potatoes that weighed 2.25 pounds, 2 boxes of raisins that total weighed 0.750 pounds (0.375 x 2), and 2 bags of apples that weighed 3 pounds total (1.5 x 2), the total weight of the merchandise purchased by Ben was 6 pounds.
Now, since his brother carried a bag of apples, which weighed 1.5 pounds, the total weight carried by Ben was 4.5 pounds (6 - 1.5).
