they are the same but the seccond one is minus so the lines go the opposite way

Step-by-step explanation:

y=3x-5

6x+3y=15

6x+3(3x-5)=15

6x+9x-15=15

15x-15=15

+15 +15

15x=30

/15. /15

x=2

6(2)+3y=15

12+3y=15

-12. -12

3y=3

/3 /3

y=1

(2,1)

The answer is (2,1)

Step-by-step explanation:

6x + 3(3x - 5) = 15

6x + 9x - 15 = 15

15x - 15 = 15

+15 +15

15x = 30

/15 /15

x = 2

6(2) + 3y = 15

12 + 3y = 15

-12 -12

3y = 3

/3 /3

y = 1

(2, 1)

This should be right if it is please make me brainliest.

Step-by-step explanation:

Answer:

a. 76 b. 190

Step-by-step explanation:

a. Number of white lights

Since the ratio of blue lights to white lights is 3 to 2 and the number of blue lights is 114, it follows that 3 : 2 = 114 : x where x is the number of white lights.

So, 3/2 = 114/x

cross-multiplying,

3x = 114 × 2

3x = 228

x = 228/3

x = 76

b. Total number of lights

So, the total number of lights is thus number of blue lights + number of white lights = 114 + 76 = 190

Answer:

B = -3

Step-by-step explanation:

Answer:

The interest is: $2550.00

Step-by-step explanation:

I = P x r x t

    P is the principal amount, $12000.00.

   r is the interest rate, 4.25% per year, or in decimal form, 4.25/100=0.0425.

   t is the time involved, 5....year(s) time periods.

   So, t is 5....year time periods.

To find the simple interest, we multiply 12000 × 0.0425 × 5 to get that:

The interest is: $2550.00

Answer:

y = 2[tex]\sqrt{5}[/tex], if you plug into expressions for angles K and J they equal 80°

Step-by-step explanation:

from notations given it appears that ΔFKH is similar to ΔIJG, which means their angles are congruent

therefore, we can say that 4y² = 6y² - 40

-2y² = -40

y² = 20

y = √20 or 2√5

to find the measure in degrees, plug 2√5 into each expression:

4 · (2√5)² = 4 · 4 ·5 = 80°

6 · (2√5)² = (6 · 4 ·5) - 40 = 80°

Answer:

A-J=4

B-G=50

C-F=2

D-I=32

E-H=8

Answer:

21.25

Step-by-step explanation:

The sum of all angles in a triangle equals 180°

Since it's an isosceles triangle, the base angles are congruent.

180 = 75 + (2x + 10) + (2x + 10)

180 = 95 + 4x

-95    -95

85 = 4x

x = 21.25

1,081,620

2 x 2 is 4

9 x 30045 is 270,405

so 4 x 270,405 is 1,081,620

Answer:

The length of one of the spoke is 7 m

Option C is correct answer.

Step-by-step explanation:

Area of Ferris Wheel = 154 square meters.

We need to find  the length of one of the spokes.

We are given: Assume  the spokes go from the centre to the edge of the Ferris wheel.

So, We are given area of circle and we need to find radius of circle.

The formula used is: [tex]Area\:of\:circle=\pi \:r^2[/tex]

Putting values and finding radius

[tex]Area\:of\:circle=\pi \:r^2\\154=3.14\:r^2\\r^2=\frac{154}{3.14}\\r^2=49\\Taking\:square\;root\\\sqrt{r^2}=\sqrt{49}\\r=7\:m[/tex]

So, Radius of circle = 7 m

The length of one of the spoke is 7 m

Option C is correct answer.

Answer:

x=17

Step-by-step explanation:

So first we know that vertical angles are equal

And for the first part we have a 73 and x

So 73+x=90 Becuase in this situation if you add them up its gonna give you a right angle

you’ll get 17

SO 17 is X

Answer:

Step-by-step explanation:

Some of the expressions that can be derived that have the values of 12 are:

i. 2a = 2 x 6

      = 12

ii. 3b = 3 x 4

        = 12

iii. (b  + c) x a = (4 - 2) x 6

                = 2 x 6

                = 12

iv. 2b + [tex]c^{2}[/tex] = (2 x 4) + (-2 x -2)

                = 8 + 4

                = 12

v. [tex]b^{2}[/tex] -  [tex]c^{2}[/tex] = (4 x 4) - (-2 x -2)

             = 16 - 4

             = 12

vi. [tex]c^{4}[/tex] - b = (-2 x -2 x -2 x -2) + 4

             = 16 - 4

             = 12

Answer: 73%

Step-by-step explanation:

The plant is capable of producing 10 tons of product in one day.

Currently however, it is only able to produce 7.3 tons per day.

Utilization is therefore:

= Actual production/ Potential production * 100

= 7.3/10 * 100

= 73%

Answer:

c + d = 400

0.2c + 0.5d = 156

Step-by-step explanation:

Let

c = number of liters of 20% acid solution

d = number of liters of 50% acid solution.

c + d = 400 (1)

0.2c + 0.5d = 400(0.39)

0.2c + 0.5d = 156 (2)

From (1)

c = 400 - d

Substitute c = 400 - d into (2)

0.2c + 0.5d = 156 (2)

0.2(400 - d) + 0.5d = 156

80 - 0.2d + 0.5d = 156

- 0.2d + 0.5d = 156 - 80

0.3d = 76

d = 76/0.3

d = 253.33 liters

Substitute d = 253.33 into (1)

c + d = 400

c + 253.33 = 400

c = 400 - 253.33

c = 146.67 liters
