Mathematics

Otrada [13]3 years ago

Recall that the slope or gradient of a line segment through two points is the ratio of the change in the <em>y</em> coordinate to the change in the <em>x</em> coordinate.

If the gradient is 1, then

1 = (-3 - 4) / (<em>a</em> - 3<em>a</em>)

Solve for <em>a</em> :

1 = -7 / (-2<em>a</em>)

1 = 7/(2<em>a</em>)

2<em>a</em> = 7

<em>a</em> = 7/2

Liam went to the zoo with his parents and a ticket for the zoo cost's him $5.3. It costs an adult $10.70. How much would it cost
jarptica [38.1K]

Answer:

If 4 more kids came to the zoo with Liam and his two parents, and so did 4 more adults, the price they would pay would be:

5.3(5) + 10.7(6)

90.7

So, it would cost a total of $90.70 dollars for Liam, his two parents, four other friends, and four other parents, to come to the zoo.

Let me know if this helps!
