Answer:

y=5.44

Step-by-step explanation:

47+16y=134 subtract 47 from both sides

16y=87

y=5.44

Answer:

[tex]x=-11[/tex]

Step-by-step explanation:

So we have the equation:

[tex]5+(x-2)=-8[/tex]

Let's subtract 5 from both sides:

[tex](5+(x-2))-5=(-8)-5[/tex]

The left side will cancel. Subtract on the right:

[tex]x-2=-13[/tex]

Now, add 2 to both sides:

[tex](x-2)+2=(-13)+2[/tex]

Again, the left side will cancel. Add the right:

[tex]x=-11[/tex]

And we're done!

Answer:

it should be x=5

Step-by-step explanation:

5+(x-2)= -8

3+x=8

Step-by-step explanation:

Answer:

20 seconds

Step-by-step explanation:

Alarm 1 = every 10 seconds

Alarm 2 = every 5 seconds

Alarm 3 = every 4 seconds

If they all go off at the same time due to a loud clap of thunder, how long will it take until they all sound at the same time again?

To determine how long it will take until they all sound at the same time again, find the lowest common multiple of the three alarm

Alarm 1 (every 10 seconds) = 20, 30, 40, 50, 60, 70, 80, 90,

Alarm 2 (every 5 seconds) = 10, 15, 20, 25, 30, 35, 40, 45, 50

Alarm 3 (every 4 seconds) = 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48

The lowest common multiple of Alarm 1 (every 10 seconds), Alarm 2 (every 5 seconds) and Alarm 3 (every 4 seconds) is 20 seconds

Therefore, they will all sound at the same time again in the next 20 seconds

Answer:

z = - 6 - 14x

Step-by-step explanation:

Given

z - 7x(- 2) = - 6 , that is

z + 14x = - 6 ( subtract 14x from both sides )

z = - 6 - 14x

Answer:

2

Answer:

r = 7

Step-by-step explanation:

Step 1: Write out equation

4r + 7 = 35

Step 2: Subtract 7 on both sides

4r + 7 - 7 = 35 - 7

4r = 28

Step 3: Divide both sides by 4

4r/4 = 28/4

r = 7

Solve 4r+7=35

4r=35-7

4r=28

r=7

Answer:

15

Step-by-step explanation:

The product of the prime factors of 3375 are

3375 = 3³ × 5³, then

[tex]\sqrt[3]{3375}[/tex]

= [tex]\sqrt[3]{3^3(5^3)}[/tex]

= [tex]\sqrt[3]{3^3}[/tex] × [tex]\sqrt[3]{5^3}[/tex]

= 3 × 5

Answer:

D) 3x + 15 ≥ 300

Step-by-step explanation:

The rectangle must have a area of AT LEAST 300 square ft, or 300 or greater. Use the greater than or equal sign: ≥ 300.

Note that your are solving for the area, and that this shape is a rectangle. To get the area of the rectangle, simply multiply length and width:

(3) * (x + 5) = Area of rectangle.

Distribute the 3 to all terms:

3(x + 5) = 3x + 15 = Area of rectangle.

Put the two parts together:

3x + 15 ≥ 300.

~

Answer:

The last answer.

Step-by-step explanation:

The area of a rectangle is

Area=(width)*(length)

If we substitute the 2 given values into the formula we will get

Area= 3(x+5)

=3x+15

Since it's asking that it has to be "at least 300", it's saying that the equation has to be 300 or more.

3x+15>(less than or equal to) 300.

The equation that has a graph with a y-intercept of -8 is y =3x - 8. The correct option is A. y =3x - 8

To determine which of the given equations has a graph with a y-intercept of -8.

We will compare the equations with the slope-intercept form of the equation of a straight line.

The slope-intercept form of the equation of a straight line is

y = mx + c

Where m is the gradient or slope

and c is the y-intercept

By comparing with y = mx + c

m = 3 and c = -8

∴ The y-intercept here is -8

By comparing with y = mx + c

m = -8 and c = 3

∴ The y-intercept here is 3

This can be written as

y = (3/8)x + 5/8

By comparing with y = mx + c

m = 3/8 and c = 5/8

∴ The y-intercept here is 5/8

This can be written as

y = (8/3)x - 5/3

By comparing with y = mx + c

m = 8/3 and c = - 5/3

∴ The y-intercept here is -5/3

Hence, the equation that has a graph with a y-intercept of -8 is y =3x - 8. The correct option is A. y =3x - 8
