Answer:

2x+5=19

2x=19-5

x=14/2

x=7

Answer:

[tex] \large \boxed{x = 7}[/tex]

Step-by-step explanation:

Goal

Given

[tex]2x + 5 = 19[/tex]

Step 1

[tex]2x + 5 - 5 = 19 - 5 \\ 2x + 0 = 14 \\ 2x = 14[/tex]

Step 2

[tex] \frac{2}{2} x = \frac{14}{2} \\ \frac{1}{1} x = 7 \\ 1x = 7 \\ x = 7[/tex]

Step 3 (Optional)

[tex]2x + 5 = 19[/tex]

Substitute x = 7 in the equation.

[tex]2(7) + 5 = 19 \\ 14 + 5 = 19 \\ 19 = 19[/tex]

The equation is true for x = 7. Hence, the answer is x = 7.

Answer: (B) SinA = 4/5

Step-by-step explanation: Sine= O/H or opposite of hypotenuse so in regards to the triangle opposite is 28 and hypotenuse 35 or 28/35 which also equals 4/5

Answer:

1. x= 5, x=1

2. x= -4, x=2

3. x= -6, x=7

4. x= -7, x=5

5. x= -9, x=0

Step-by-step explanation:

You do the X factoring-

1.

A   B   C

x²+6x+5

(A)(C) and B

(1)(5)=5      6

Then figure out what two numbers multiply to get 5

but also add to 6. In this case, it would be 5 and 1

5x1= 5 and 5+1= 6

so it is:

x= 5, x= 1

Hope this helps!

Answer:

The linear speed in which Darlene is traveling is 24.74 miles per hour.

Step-by-step explanation:

The wheel experiments rolling, which is a combination of translation and rotation. The point where linear speed happens is located at geometrical center of the wheel and instantaneous center of rotation is located at the point of contact between wheel and ground. The linear speed ([tex]v[/tex]), measured in inches per second, is defined by following expression:

[tex]v = R\cdot \omega[/tex] (1)

Where:

[tex]R[/tex] - Radius of the wheel, measured in inches.

[tex]\omega[/tex] - Angular speed, measured in radians per second.

If we know that [tex]R = 11\,in[/tex] and [tex]\omega \approx 39.584\,\frac{rad}{s}[/tex], then the linear speed, measured in miles per hour, in which Darlene is traveling is:

[tex]v = 11\,in\times \frac{1\,mi}{63360\,in} \times 39.584\,\frac{rad}{s}\times \frac{3600\,s}{h}[/tex]

[tex]v \approx 24.74\,\frac{mi}{h}[/tex]

The linear speed in which Darlene is traveling is 24.74 miles per hour.

Answer:

x    10    4    6     1

y     5    2     3    0.5

Step-by-step explanation:

You have to start with a guess and see if it works. If it works, you're done. If it doesn't work, you need to make a difference guess.

I'll start by guessing that above the 0.5 is a 1.

If that is correct, then every x value is double the y value below it.

5 goes below the 10. 3 goes below the 6. Then you have 4 and 2 left.

That is every whole number from 1 to 5. It works.

x    10    4    6     1

y     5    2     3    0.5

Answer:

40%

Step-by-step explanation:

Answer:

40%

Step-by-step explanation:

To convert 2/5 to a percent, we need the denominator to be 100 .

2/5 = 40/100

Now that you have have a denominator equal to 100, just look at the numerator.

40% or 0.4

Answer:

8

Step-by-step explanation:

have a good day

Answer:

The Answer is 8

Step-by-step explanation:

Hello,

The answer to the question is 8, let me explain why.

1. we know how many balloons Fred can blow up in 15 minutes

Fred can blow up 20 balloons in 15 minutes.

2. we need to find out how many balloons Fred can blow up in 1 minute.

To solve this we just divide 20 by 15

20 ÷ 15 = 1.3 (repeated)

3. Finally we multiply the answer by 6

This will give us the answer of 8

because 1.3 × 6 = 8

Hope I could help, Hope it was easy to understand as well.

Answer:

11:5

Step-by-step explanation:

The computation is shown below:

Given that

Cube root of 1331: reciprocal of 0.2

11: 5

So here n denotes the 11

And, 1 denotes the 5

Therefore the answer is 11:5

Hence, the same would be considered and relevant too

Answer:

1/9

Step-by-step explanation:

To find this probability, we simply divide the number of yellow marbles by the total number of marbles

From the question, there are a total of 18 marbles and 2 yellow ones

thus, the theoretical probability of selecting a yellow marble will be;

2/18 = 1/9
