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.

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

Answer:

G. 7(200)+7(10)

Step-by-step explanation:

First, you would multiply 200 by 7

Once you do that you should get 1400

After that you mulitply 7 by 10

You should get 70

Add 1400 by 70 and there you go your answer 1,470

Answer:

7(200)+7(10)

Step-by-step explanation: it is quite simple.first you look at the number out side of the () and that is the first number of your answer.then you look at the other number and split it into the 100 place and the tenth place.finally you know it is G because you have to have the () in the answer so it is G.

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 =)

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.

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;

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;

Substituting into the equation, we have;

[tex] CSA = 3.142*6*10 [/tex]

CSA = 188.5 cm² (to 1d.p)

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.

Given:

A blueprint of a house shows a wall that is 5 inches long.

The blue pretty strong to a scale of 1:60.

To find:

The actual width of the wall in the house.

Solution:

The blue pretty strong to a scale of 1:60.

It means, the dimensions of blueprint to the actual house is 1:60.

Width of a wall in blue print = 5

Let the actual width of the wall in the house be x.

[tex]\dfrac{5}{x}=\dfrac{1}{60}[/tex]

[tex]5\times 60=1\times x[/tex]

[tex]300=x[/tex]

Therefore, the width of the wall in the house is 300 inches.
