Answer:

4x + 3x = 35

Step-by-step explanation:

4x + 3x

well first let's simplify this

4x + 3x = 7x

now let's replace the variable

7x = 7 x 5

now we can do the math

7 x 5 = 35

Answer:

Simplifying

4x = 3x + 5

Reorder the terms:

4x = 5 + 3x

Solving

4x = 5 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

4x + -3x = 5 + 3x + -3x

Combine like terms: 4x + -3x = 1x

1x = 5 + 3x + -3x

Combine like terms: 3x + -3x = 0

1x = 5 + 0

1x = 5

Divide each side by '1'.

x = 5

Simplifying

x = 5

Find a.<br> Round to the nearest tenth:<br> 2 cm<br> с<br> 150<br> 1050<br> a =<br> = [? ]cm
VLD [36.1K]

Answer:

a = 1.8 cm

Step-by-step explanation:

Here. we want to find the value of a

To do this, we are going to use the sine rule

it states that the ratio of a side and the sine of the angle that faces the side is a constant for all the sides of a triangle

From the diagram, we have that;

The angle facing a is;

180-15-105 = 60

So, we have that

a/sin 60 = 2/sin 105

a = 2sin 60/sin 105

a = 1.794 cm

Pls Show your work on the slope
Semmy [17]

Answer:

1) slope = 1/5

x - intercept = (10, 0)

y - intercept = (0,-2)

2) use the method I used for number one to do number 2.

Step-by-step explanation:

slope = rise/run = y2-y1/x2-x1

1)

use any 2 points on a line. Chose one y-value which is y2 and the corresponding x-coordinate is x2. In the other coordinates, the y-value is y1 and the x-value is x1. Let's use points:

(-10, -4)

(-5, -3)

y2 = -3, which means:

y1 = -4

x1 = -10

x2 = -5

plug in the values:

-3-(-4)/-5-(-10)

=1/5

X - intercept is when y = 0. Plug in 0 for y when you see it.

x-0 = 10

x=10

x-intercept = (10,0)

Same for y intercept, except x = 0 this time.

0-5y=10

-5y=10

y=-2

y-intercept = (0,-2)
