Rufus collected 18 pounds of aluminum cans to recycle. He plans to collect an additional 2 pounds each week. He wants to collect a total of 42 pounds of aluminum cans. Let x represent the number of weeks Rufus collects aluminum cans.

12 weeks

Step-by-step explanation:

Given

weekly

Required

Determine the number of weeks

Represent the maximum number of pounds with y and the number of weeks with x.

Such that

From the given parameters, the relationship between y and x is as follows:

Substitute 42 for y and 18 for base value

Subtract 18 from both sides.

Divide both sides by 2

Hence, the number of weeks is 12

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
