The solution to the system of linear equation is (x, y) = (6, 2)

3x - 2y = 14 (1)

3x - 2y = 14 (1)5x + y = 32 (2)

From (2)

y = 32 - 5x

Substitute y = 32 - 5x into (1)

3x - 2y = 14 (1)

3x - 2(32 - 5x) = 14

3x - 64 + 10x = 14

13x = 14 + 64

13x = 78

x = 78/13

x = 6

Substitute x = 6 into (2)

5x + y = 32 (2)

5(6) + y = 32

30 + y = 32

y = 32 - 30

y = 2

(x, y) = (6, 2)

Answer:

x = -2 and y = 3

Step-by-step explanation:

In linear combination method we try one of the variables from bopth of equations by

first making the variable equal in vlaue

then either subtracting or adding the two equation as required to eliminate the variable.

_____________________________________________

7x-2y=-20   equation 1

and 9x+4y=-6   equation 2

we see that y has

has value -2 and +4

4 = 2*2

thus, if we multiply equation1 with 2 we will give value for variable y as 4y and hence y can be eliminated easily.

7x-2y=-20  

multiplying the LHS and RHS with 2

2(7x-2y)=-20 *2

=> 14x - 4y = -40   eqaution 3

now that we have got 4y

lets add equation 2 and equation 3

  9x +4y=   -6

+14x - 4y = -40

________________________________

=> 23x + 0 =  -46

x = -46/23 = -2

Thus, x = -2

substituitinng x = -2 in 7x-2y=-20

7*-2 -2y=-20

=> -14 -2y = -20

=> -2y = -20+14 = -6

=> y = -6/-2 = 3

Thus, y = 3

solution is x = -2 and y = 3

Step-by-step explanation:

The canister has a cylindric form

The volume of a cylinder is given by the following formula :

V= r^2 * Pi *h

H is the heigth and r os the radius(half of the diameter)

Let Pi = 3.14

●●●●●●●●●●●●●●●●●●●●●●●●

V= 3.14*4.5^2 * 12

V= 763.02

V = 763 cm^3(after rounding to the nearest unit)

●●●●●●●●●●●●●●●●●●●●●●●●

The surface area of a cylinder is given by the followong formula:

Sa = 3.14*r^2*2 + Pi*d*h

r is the radius, d the diameter and h the heigth

Let Pi= 3.14

Sa= 3.14*4.5^2*2 + 3.14*9*12

Sa= 466.29 cm^2

Sa= 466 cm^2 ( after rounding to the nearest unit

●●●●●●●●●●●●●●●●●●●●●●●●

The dimensions of the second canister are the double of the first one

V= r^2*Pi*h

V= 9^2 *3.14*24

V= 6104.16 cm^3

V= 6104 cm^3 (after rounding to the neatest unit)

Sa= 2*3.14*r^2+ 3.14*d*h

Sa= 2*3.14*9^2 + 3.14*24*18

Sa= 1865.16 cm^2

Sa= 1865 cm^2 (after roundong to the nearest unit)

●●●●●●●●●●●●●●●●●●●●●●●●

The volume and the surface area of the second canister are bigger than the first one

Divide the second volume by the first one :

V2/V1= 6104/763 = 8

We deduce that the voulme of the second canister is greater 8 times than the first one

Do the same for the surface area

Sa2/Sa1 = 1865/466 = 4.002 = 4 (after rounding to the nearest unit)

The second surface area is greater 4 times than the first one

Answer:

144 units²

Step-by-step explanation:

Surface area of a traingular prism is given as:

Area = 2(B.A) + P*L

Where,

B.A = base area of the triangular prism = ½*b*h

b = base of the triangular base = 4 units

h = height of the triangular base = 3 units

Base Area (B.A) = ½*4*3 = 2*3 = 6 units²

P = Perimeter of triangular face = sum of all sides the triangle = 3 + 4 + 5 = 12 units

L = length or height of prism = 11 units

Plug in all values into the formula for surface area of triangular prism = 2(B.A) + P*L

[tex] Area = 2(6) + 12*11 [/tex]

[tex] = 12 + 132 [/tex]

Answer:

1.  20 tins of milk

2.  Weight of the Carton = 8,4kg ot 8400g

Step-by-step explanation:

Given

Volume of a Tin = 77cm³

Weight of a tin = 5000g

Volume of Empty Carton = 1540cm³

Weight of Empty Carton = 5000g

Calculating the number of tins of milk

To do this, we have to make use of the given volumes;

And this is done as follows;

[tex]Number = \frac{Volume\ of\ Empty\ Carton}{Volume\ of\ a\ Tin}[/tex]

Substitute  77cm³ for Volume of a Tin and 1540cm³ for Volume of an Empty Carton

[tex]Number = \frac{1540cm^3}{77cm^3}[/tex]

[tex]Number = 20[/tex]

Hence, 20 tins of milk will filled the empty carton

Calculating the weight of the Carton after filled with tins of milk

This is calculated as thus;

Total Weight = Weight of Empty Carton + Weight of Tins of Milk

Substitute 5000g for Weight of Empty Carton

Total Weight = 5000g + Weight of Tins of Milk

_________________________________________

Calculating Weight of Tins of Milk

Since 20 tins of milk will fill the empty carton, the

Weight of Tins of Milk = 20 * Weight of 1 Tin of Milk

Weight of Tins of Milk = 20 * 170g

Weight of Tins of Milk = 3400g

_________________________________________

Substitute 3400g for Weight of Tins of Milk

[tex]Total\ Weight = 5000g + 3400g[/tex]

[tex]Total\ Weight = 8400g[/tex]

In Kilograms:

[tex]Total\ Weight = 8.4kg[/tex]

x = 1

y = 2

Step-by-step explanation:

3y +   x = 7       first equation

-2y + 4x  = 0      second equation

multiplying by -4 the first equatión

-4(3y + x = 7)

-4*3y -4*x = -4*7

-12y -4x = - 28

and sum the second equation:

-12y -  4x = -28

- 2y - 4x  =  0

-14y   -  0  =  -28

-14y = -28

y = -28/-14

y = 2

from the first equation:

3y + x = 7

3*2 + x = 7

6 + x = 7

x = 7 - 6

x = 1

Check:

from the second equation:

4x - 2y = 0

4*1 - 2*2 = 0

4 - 4 = 0

Answer:24

Step-by-step explanation:

24*5=120.

So the difference between 120-24=96.

The required number, one number is 5 times another and their difference is 96 is 24 and 120.

One number is 5 times another. If their difference is 96, To find the numbers.

In mathematics, it deals with numbers of operations according to the statements.

Let the number be x and y
According to the first condition,
One number is 5 times another.So,
y = 5x

Following the second condition,
their difference is 96. So,
y - x = 96 - - - - - (1)
Now put y = 5x in the above equation
5x - x = 96
4x = 96
x = 96/4
x = 24
Now put x = 24 in y = 5x
y = 5*24
y = 120

Thus the required number, one number is 5 times another and their difference is 96 is 24 and 120.

Answer:

D. Exponential growth will always exceed linear growth.

Step-by-step explanation:

An "exponential growth function" would always exceed the "linear growth function" in the end because the "x-values" tends to get larger in continuation, so the change rate associated with the "exponential function" also increases in continuation whereas the "linear functions' change rate is considered as constant.

In the question above, option D is correct.

Answer:

g = (h+a) - l

None of them

Step-by-step explanation:

Suppose your car has h liters of engine oil in the morning. During the day, some oil may have leaked, you may have added more oil, or both. The oil level in the evening is g liters. Which of the following expressions always represents how far away the new oil level is from the previous oil level? H+G lGl none of them

Let

h = liters of oil in the morning

l= liters that has leaked

a= liters that were added during the day

g= amount of liters at the end of the evening

Total liters of oil in the evening= (litres of oil in the morning + litres of oil added during the day) - litres of oil that leaked

Substituting each variable into the formula, we have

g = (h+a) - l

Answer:

a = 7

b = 7

c = 14             [Correct option is B. 14]

Step-by-step explanation:

Since the shape is a parallelogram, to solve this problem, use some of the properties of a parallelogram:

(i) Opposite sides are parallel and congruent. Being congruent means the sides are identical. In other words, they have the same length.

From the diagram, this means that sides PQ and SR are identical. i.e

=> PQ = SR

=> 6a + 10 = 8a - 4          [collect like terms and solve]

=> 14 = 2a

=> a = 7

(ii) Opposite angles are congruent. Angles PQR and PSR are identical. i.e

<PQR = <PSR = (9b + 2)°

Also,

<SPQ = <SRQ = (18b - 11)°

(iii) Consecutive angles are supplementary. The sum of any two angles that are not opposite to each other is 180°. i.e.

<SPQ + <PQR = 180°

<PQR + <QRS = 180°

<QRS + <RSP = 180°

.

.

.

Also,

<PSR + <SPQ = 180°      

(9b + 2)° + (18b - 11)° = 180°        [expand bracket and solve for b]

9b  + 2 + 18b - 11 = 180

27b - 9 = 180

27b = 189

b = 7

Now, since a = 7 and b = 7;

c = a + b = 7 + 7 = 14

Therefore;

a = 7

b = 7

c = 14
