4) -8 – 3a = 46 whoever has best answer gets brainliest
Answer:
A= -18
Step-by-step explanation:
-8-3(-18)= 46= -18
Answer:
a=-18
Step-by-step explanation:
Let's break this down step by step.
-8-3a=46
Since 3a has a variable, a, we want to get it by itself. So the first step is to do the inverse operation and add 8 on both sides. That leaves this equation:
-3a=54
The 3a is -3a because of the subtraction sign in front. Now we divide on both sides because we want the variable, a, to be by itself. That leaves this simplified expression.
a=-18.
Now, let's work it out in context of the problem.
-8-3x-18=46
3x-18 is -54, and -8-(-54), it would become 46.

A pharmacist need to fill an order for a patient weighing 90.0 kg. The patient was prescribed 15 mg of a drug per
kg of body weight (15 mg = 1 kg) How many milligrams (mg) will the pharmacist need to order for the
prescription for the 90.0 kg patient?
Answer:
1,350 mg.
Step-by-step explanation:
Multiply the amount of mg per kg by the number of kg to get the total amount of mg needed by the patient.
1350 milligrams pharmacist needs to fill the order for that patient.
What is multiplication?Multiplication is the general procedure in mathematics in which we multiply two or more numbers to each other to find a new multiplied number.
Multiplication gives us a resultant number that will be very big as compared to the number which is going to be multiplied if and only if the number which is going to be multiplied is more than one.
Given that,
The patient needs the drug according to his weight by multiplying of 15
Since the weight of the patient is 90 kg
So,
Amount of drug needed = 15 × 90 = 1350 miligram.
Hence "1350 milligrams pharmacist needs to fill the order for that patient".

give the equation of the line goinng through (4, 6) and parallel to the line 2y-6x=4
Answer:
y = 3x-6
Step-by-step explanation:
First we need to find the slope of the line
2y-6x=4
Solve for y
Add 6x to each side
2y-6x+6x=4+6x
2y = 6x+4
Divide each side by 2
2y/2 =6x/2 +4/2
y = 3x +2
The slope is 3
We want a line parallel, so it will have the same slope
We have a slope and a point
y = 3m+b
Substitute in the point
6 = 3(4)+b
6 =12+b
Subtract 12 from each side
6-12 = 12-12+b
-6 =b
y = 3x-6
Answer:
y = 3x - 6
Step-by-step explanation:
2y = 6x + 4
y = 3x + 2
Slope = 3
y = 3x + c
6 = 3(4) + c
c = 6 - 12
c = -6
y = 3x - 6

Mr. Wilson is putting together information package for his students. Each package has 5 sheets of paper and is held together with 2 Staples. What ordered pair represents how many staples (x) and sheets of paper (y) Mr Wilson needs for 13 packets?
Answer:
(26,65)
Step-by-step explanation:
We know that each package has 5 sheets of paper and 2 staples. So, to know how many sheets of paper and staples that will be used in 13 packages, we just need to multiply each quantity of material used by 13.
So, we have that:
Total sheets of paper = 13 * 5 = 65
Total staples = 13 * 2 = 26
So the ordered pair (x,y), where x is staples and y is sheets of paper is:
(26,65)
Answer:
The ordered pair is (26, 65).
Step-by-step explanation:
From the given information, a package has 5 sheets of paper and is held together with 2 staples.
13 packets contains 13 packages, so that:
Number of sheet of paper required = 13 × 5
= 65
Number of staples required = 13 × 2
= 26
Therefore, the ordered pair is; staples (26) and sheets of paper (65) i.e (26, 65).
A line passes through the point (4, -1) and has a slope of -5/4
Answer:
y = -5/4x+4
Step-by-step explanation:
We can use the slope intercept form of a line
y = mx+b
where m is the slope and b is the y intercept
y = -5/4x +b
Substitute the point into the equation
-1 = -5/4(4) +b
-1 =-5+b
Add 5 to each side
-1+5 = -5+5+b
4 = b
y = -5/4x+4

How many integers are there in the solution set of the inequality |x−2000|+|x| ≤9999
Answer:
9999
Step-by-step explanation:
Find the greatest value of x and the least value of x that satisfy the equation:
2x-2000 = 9999 (Yields the greatest solution)
2x + 2000 = -9999 (Yields the least solution)
Solve both equations and you get:
3999.5 (Greatest solution)
-5999.5 (Least solution)
That means the range of integer solutions is between 3999 and -5999 (inclusive). That means there are 9999 integral solutions
Answer:
20,000 integers
Step-by-step explanation:
By triangular inequality,
|x - 2000 + x| ≤ |x−2000|+|x|
|x−2000|+|x| ≤ 9999
|x - 2000 + x| ≤ 9999
|2x - 2000| ≤ 9999
|x - 10000| ≤ 4999.5
x - 10000 ≤ 4999.5
x ≤ 4999.5
x ≤ 14999.5
-(x - 10000) ≤ 4999.5
-4999.5 ≤ x - 10000
-5000.5 ≤ x
All solutions:
-5000.5 ≤ x ≤ 14999.5
No. of inyegers:
14999 - (-5000) + 1

Joey's cleaning service charges $50 per week to clean a home. Amy's cleaning service charges $50 per week , plus $25 for cleaning supplies.
which equation can be used to express the amount that Amy's cleaning service charges?
A y=50x
B y=50x-25
C y=1/50x
D y=50x + 25
Answer:
D y=50x + 25
Step-by-step explanation:
The number of weeks can vary, so it is placed in front of a variable. The cleaning supplies cost does not, so it does not have a variable, but instead, it is a constant.
Answer:
D
Step-by-step explanation:
y = mx + b is the equation, where m = cost per week and b = cleaning supply cost (constant)
That means the equation is y = 50x + 25

Which set of line segments could create a right triangle? (4 points)
O 15,30,35
O 15,36,39
O 15, 20, 29
O 5,15,30
Answer:
(B)15,36,39
Step-by-step explanation:
To determine which of the line segments could create a Right Triangle, we check if it satisfies the Pythagoras Theorem, taking the longest part to be the Hypotenuse in all cases.
By Pythagoras Theorem: [tex]Hypotenuse^2=Opposite^2+Adjacent^2[/tex]
In 15,30,35
[tex]35^2\neq 15^2+30^2\\1225\neq 1125[/tex]
In 15,36,39
[tex]39^2=36^2+15^2\\1521=1521[/tex]
In 15, 20, 29
[tex]29^2\neq 15^2+20^2\\841\neq 625[/tex]
In 5,15,30
[tex]30^2\neq 15^2+5^2\\900\neq 250[/tex]
We can see that only 15,36,39 satisfies the required condition and thus it could be used to create a right triangle.

A boy owns 7 pairs of pants, 3 shirts, 2 ties, and 6 jackets. How many different outfits can he wear to school if he must wear one of each item?
He can wear different outfits.
Answer:
252 7 x 3 x 2
Step-by-step explanation:
The boy can wear 252 different outfits to school.
To calculate the number of different outfits, you can multiply the number of choices for each clothing item.
In this case, he has 7 choices of pants, 3 choices of shirts, 2 choices of ties, and 6 choices of jackets.
To find the total number of outfits, simply multiply these choices together: 7 pants x 3 shirts x 2 ties x 6 jackets = 252 different outfits.
This calculation works because for each choice of one item of clothing, there are still all the other choices available for the remaining items.
So, for every pair of pants, he can choose from 3 different shirts, and for each shirt-pants combination, there are 2 tie options, and so on.
Multiplying these choices together gives us the total number of outfits he can create while wearing one of each item.

What percent represents the probability that the spinner will stop on a yellow section?
A.
20%
B.
30%
C.
40%
D.
80%
To calculate the probability of a spinner landing on a yellow section, specific information about the spinner is required. For instance, with 5 sections where 1 is yellow, the probability would be 20%. Without such information, however, the correct percentage cannot be determined from the choices provided.
Explanation:To determine the probability of the spinner stopping on a yellow section, we need specific information about the spinner such as the number of sections and the number of yellow sections. Without this information, we are unable to calculate the exact percentage. Assuming a student is given this type of probability question, they would typically be provided with a diagram or description of the spinner. For example, if there are 5 equal sections and 1 of those is yellow, then the probability (in percentage) would be 20%, calculated as (1 yellow section / 5 total sections) × 100%. However, since we do not have this information here, the correct option cannot be determined from the choices provided (A. 20%, B. 30%, C. 40%, D. 80%).
As for the probability of a randomly chosen student not living within five miles of the campus, this would typically be based on specific data provided in the context of the problem. Without the data, we cannot determine the correct percentage for this scenario as well, thus the correct answer is "Cannot be determined."
