A company has two manufacturing plants with daily production levels of 7x+19 items and 5x−2 items, respectively. The first plant produces how many more items daily than the second plant?
Answers
Answer:
The first plant manufactures 2x + 21 more items daily.
Step-by-step explanation:
Given that:
Production level of plant one = 7x + 19
Production level of plant two = 5x -2
To find the number of items first plant manufactures more than second plant, we will find the difference between production levels.
Difference = (7x + 19) - (5x - 2)
Difference = 7x + 19 - 5x + 2
Difference = 2x + 21
Hence,
The first plant manufactures 2x + 21 more items daily.
What should be done to these equations in order to solve a system of equations by elimination?
-3x+2y=16
2x+5y=21
A. Nothing needs to be done, since they both equal have 2’s and 3’s for coefficients.
B. Multiply the first equation by 3 and the second equations by 2.
C. Multiply the first equation by 2 and the second equation by 3.
D. Multiply the first equation by 3.
Answers
Answer:
The answer is C.
Step-by-step explanation:
I did the test and got it right. :)
The correct is C = Multiply the first equation by 2 and the second equation by 3.
What is system of equations by elimination?The elimination method exists utilized to solve a system of linear equations. It is the most widely used and simple method as it concerns fewer calculations and steps. In this manner, we eliminate one of the two variables and test to solve equations with one variable.
if we'll multiply the first equation by 2 and second by 3 we will be able to solve the equation by elimination.
(-3x+2y=16) X 2 = -6x + 4y = 32
(2x+5y=21) X 3 = 6x + 15y = 63
the coeffients of x gets cancelled out on adding the new equations
4y+ 15y = 32+ 63
19y = 95
y= 95/19

The amount of money that Ariana needs to invest today in order to reach $25,000 in 14 years is $14,913.
How much should Ariana invest today?In order to determine the amount of money that Ariana should invest today, the present value of $25,000 has to be determined.
The formula that can be used to determine the present value is:
P = FV / (1 + r)^nm
Where:
FV = Future value P = Present value R = interest rate = 3.7% / 12 = 0.308%m = number of compounding = 12N = number of yearsP = 25,000 / (1.00308)^(12 X 14) = $14,913

Of the 40 randomly chosen students surveyed, 27 are involved in extracurricular activities at school. There are 680 students at the school. Predict the number of students in the school who are involved in after-school activities. (Please answer the right answer and how you got the answer)
Answers
Answer:
It's around 459. So 460 if need to round
Step-by-step explanation:
So, 40 randomly chosen people do not represent the whole school, but using the ratio 27:40 you are given in the equation, you can divide the number of students (680) by the surveyed students (40) to get 17. What this means is there is 17 groups of 40 in the school, so to distribute the amount of people who are in a after-school activity, you must multiply 17 x 27 to get the assumption of about 459 kids. Hopefully you understand =)

1. Candace has $15 more than Amar. Their combined money totals $85. Which system of equations represents this situation? F. c + a = 85 G. c + a = 85 H. c – a = 85 I. c – a = 85 c – a = 15 a + c = 15 c – a = 15 c + a = 15 Also please show explanation
Answers
Explanation: Candaces total money + Amar’s total money equals out to $85, it can be wrote either way and still equal $85.
The system of equations that represents Candace's and Amar's combined money is c + a = 85.
What is a linear equation?
A linear equation is an algebraic equation of degree one. In general, the variable or the variables(in the case of a linear equation in two variables) the variables are x and y.
Given, Candace has $15 more than Amar.
Assuming Amar has $a.
∴ Candace(c) has $(x + 15).
Their combined money totals $85.
So, the equation that represents their combined money is
x + (x + 15) = 85 or a + c = 85.

Find the following, giving your answers to 1 decimal place?
Answers
Answer:
I. Volume = 301.6 cm³ (to 1d.p)
II. CSA = 188.5 cm² (to 1d.p)
Step-by-step explanation:
Given the following data;
Height, h = 8cm
Radius, r = 6cm
Curved length = 10cm
a. To find the volume of the cone
[tex] V = \frac{1}{3} \pi r^{2}h[/tex]
Where;
V is the volume of the cone.r is the radius of the base of the cone.h is the height of the cone.Substituting into the equation, we have;
[tex] Volume = \frac{1}{3} * 3.142*6^{2}*8 [/tex]
[tex] Volume = \frac{1}{3} * 3.142*36*8 [/tex]
[tex] Volume = 3.142*12*8 [/tex]
Volume = 301.6 cm³ (to 1d.p)
b. The curved surface area of the cone
[tex] CSA = \pi rl[/tex]
Where;
CSA is the curved surface area of the cone.r is the radius of the base of the cone.l is the curved length of the cone.Substituting into the equation, we have;

Answer:
Two possible equations:
[tex]y = x + 1\\y = x - 5\\[/tex]
The system has 0 solution as parallel lines never cross each other.
Step-by-step explanation:
Considering the two lines are parallel, they both have the same slope.
let m be the slope of the two lines:
[tex]y = mx + y_{0}\\y=mx+y_{1}[/tex]
[tex]y_{0}, y_{1}[/tex] are the value on y axis where the two lines cross the axis.
Because the lines are parallel, there exists no point that lies on both lines, therefore the system has 0 solution.
