Answer:

1. $33.00

2. $48.00

3. $3.00

4. $36.40

Step-by-step explanation:

44.00 - 25% = 33 —> $33.00

80.00 - 40% = 48 —> $48.00

9.99 - 70% = 2.997 —> (round the 7 up because it's above 5) $3.00

52.00 - 30% = 36.4 —> $36.40

Use the distributive property to rewrite 6(4-x)
Arlecino [84]

Answer:

24-6x

Step-by-step explanation:

To distribute, you multiply the number outside the parenthesis by each number inside, keeping in mind the signs.

So, 6(4-x) = 6(4) - 6(x) = 24-6x

What is an equation of the line that passes through the points (4,-6) and (8,-4)​
qaws [65]

Answer:

y =  \frac{1}{2} x - 8

Step-by-step explanation:

The equation of a line is usually written in the form of y=mx+c, where m is the gradient (also known as slope) and c is the y-intercept (the point through which the line cuts through the y-axis).

\boxed{gradient =  \frac{y1 - y2}{x1 - x2} }

Using the gradient formula above,

m =  \frac{ -4 - ( - 6)}{8 - 4}  \\ m =  \frac{ - 4 + 6}{4}  \\ m =  \frac{2}{4}  \\ m =  \frac{1}{2}

Substitute the value of m into the equation:

y= ½x +c

To find the value of c, substitute a pair of coordinates.

When x=4, y= -6,

-6= ½(4) +c

-6= 2 +c

c= -6 -2 <em>(</em><em>-2</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>

c= -8 <em>(</em><em>simplify</em><em>)</em>

Thus, the equation of the line is y= ½x -8.

Four consecutive positive prime numbers have a sum that is divisible by three. What is the smallest possible value of this sum?
LuckyWell [14K]

Answer:

36

Step-by-step explanation:

1 + 3 + 5 + 7 = 16

3 + 5 + 7 + 11= 26

These consecutive positive prime numbers above have sums that are not divisible by three.

5 + 7 + 11 + 13 = 36

This consecutive positive prime numbers above has a sum that is divisible by three: 36.

36 : 3 = 12
