You and your friend Sam are going to paint your 300 square feet room together.
Elza [17]
Fraction that Sam painted in 1 min is:
10/25=2/5
Fraction that you painted in 1 min:
5/25=1/5

Fraction pained by both in 1 min:
1/5+2/5=3/5 ft²/min
Time taken to paint 50 ft² will be:
time=3/5×50=30 min
Thus we conclude that Sam was wrong.

4n=1/2(2n-12) check the solution to the example problem by replacing n in the original equation with -2 and evaluating both side
worty [1.4K]

Answer:

The true statement is that the expression is satisfied for n = -2.

Step-by-step explanation:

Given:

4n = \frac{1}{2}\times (2n-12)

To check:

Left hand side = Right-hand side ( for n = -2)

Proof :

For n = -2

Consider  Left hand side of the equation given above.

∴ Left hand side = 4n

                            = 4×(-2)   ......................for n = -2

                            = -8

Consider Right-hand side of the equation given above

∴ Right-hand side = \frac{1}{2}\times (2n-12)

                              =\frac{1}{2}\times (2\times(-2) - 12) \\= \frac{1}{2}\times (-4 - 12)\\ =\frac{1}{2}\times (-16)\\ =-8

Now we get Left hand side equal to Right hand side

i.e. Left hand side = Right hand side

i.e. 4n = \frac{1}{2}\times (2n-12) is true for n = -2

The line passing through (-4,6) and parallel to the line y=3x+8
Allisa [31]
<span>y=3x+8
if it's parallel to this line, then the slope will also be 3.

slope = 3
</span><span>x</span>₁ = -4
<span>y</span>₁ = 6
<span>
</span><span>for this question, we use point-slope
y - y</span>₁ = m(x - x₁)

y + 4 = 3(x - 6)
y + 4 = 3x - 18

y = 3x - 14
this is your equation
