Last Saturday, Kevin walked his dog 1 2/7 miles. Sam walked his dog 7 times as far. How many miles total did both guys walk thei

Annette [7]

Answer:

$10\dfrac{2}{7}\ miles$

Step-by-step explanation:

If Kevin walked his dog 1 2/7 miles and Sam walked his dog 7 times as far, then Sam walked his dog

$1\dfrac{2}{7}\cdot 7=\dfrac{1\cdot 7+2}{7}\cdot 7=\dfrac{9}{7}\cdot \dfrac{7}{1}=9\ miles.$

Together they walked

$1\dfrac{2}{7}+9=10\dfrac{2}{7}\ miles.$

as of a certain date there has been a total of 18072 performances of two show on broadway with 2892 more performances of show A

Nataly_w [17]

Answer:
A = 10,482
B = 7,590

Explanation:

If A is the number of times show A was performed, and B is the number of times show B was performed:

We know that A + B = 18072
And we know A = B + 2892

So we’ll substitute the expression (B + 2892) for A in the first equation and solve for a numerical value of B:

A + B = 18072
B + 2892 + B = 18072
2B + 2892 = 18072
2B = 15,180
B = 7,590

A = B + 2892
A = 7590 + 2892
A = 10,482

Check the math
A + B = 18072
10,482 + 7,590 = 18,072

What does the line 5x + 4y = -6 look like

RoseWind [281]

Answer:

See attached photo for graph

Step-by-step explanation:

Solve the equation for y... (that means get y by itself)

4y = -5x - 6 (subtract 5x from both sides)

y = -(5/4)x - 6/4 (divide both sides by 4)

y = -(5/4)x - 3/2 (simplify)

Now you can graph using slope-intercept method. The y-intercept is -3/2, and the slope is -5/4
