11. An astronaut who weighs 180 lb on Earth weighs only 9 lb on Mars. How much would a person who weighs 13 lb on Mars weigh on Earth?
I also need fraction work

260 lb

Step-by-step explanation:

180/9=20

13*20=260

Step-by-step explanation:

Use the ratio

Simplify

Find the weight x on Earth of the person with weight 13 lb on Mars:

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
