If –3x = -18, what is the value of x?​

Mathematics

yan [13]3 years ago

-3x=-18

divide both sides by -3

to get +x

to get x by itself

-3x/-3=-18/-3

cross out -3 and -3, divide by -3

then becomes -1*-1*x=1*x=x

x=-18/-3

answer:

x=6

Answer: x = 6

Step-by-step explanation: To solve for <em>x </em>in this equation, we want to get <em>x</em> by itself on the left side of the equation. Since <em>x</em> is being multiplied by -3, to get <em>x</em> by itself, we need to divide by -3 on the left side of the equation. Since we divided by -3 on the left side, we must also divide by -3 on the right side.

On the left side, notice that the -3's cancel out so we are simply left with <em>x</em>. On the right side, we have -18 ÷ -3 which is 6 so we have x = 6.

Finally, remember to check your answer by substituting a 6 back into the original equation. So we have -3 (6) = -18 which is a true statement.

So our answer x = 6 is correct.

Remember to show all your work when solving equations.

Lisa [10]

Answer:

640 yard²

Step-by-step explanation:

From the question,

The surface are of a triangular prism is given as

A = bh+2ls+lb.................. Equation 1

Where A = Surface area of the triangular prism, b = base of of the triangular face, h = height of the triangular face, l = length of the triangular prism, s =  length of one of the other sides of the triangle

Given: l = 17 yards, b = 12 yards, h = 8 yards, s = 10 yards.

Substitute these values into equation 1

A = [(12×8)+(2×17×10)+(17×12)]

A = 96+340+204

A = 640 Yard²

Vector V is in standard position and makes an angle of 50° with the positive x-axis. Its magnitude is 18. Write V in component f
Umnica [9.8K]

Answer:

11.57 units east, 13.79 units upwards

11.57i + 13.79j

Step-by-step explanation:

V = 18 units at an angle of 50° to the positive x-axis

In component Form, this is how each component is calculated

a = 18cos50° = 11.57 units east

b = 18sin50° = 13.79 units upwards

check if your answer is correct

\sqrt{11.57^{2} +13.79^{2} } = 18.0

In vector component form ai + bj = 11.57i + 13.79j
