Felix has $11 and begins saving $5 each week toward buying a new phone. eddy has $60 and begins spending $2 per week on supplies for his art class. what is the unit rate for felix and eddy?

Unit rate for Felix= $5 per week.

Unit rate for Eddy= -$2 per week.

Step-by-step explanation:

We have been given that Felix has $11 and begins saving $5 each week toward buying a new phone. Eddy has $60 and begins spending $2 per week on supplies for his art class.

Let us find unit rate for Felix.    

We can see that unit rate for Felix is $5 per week as each next week Felix's saved amount will be $5 greater than last week, therefore, unit rate for Felix will be $5 per week.  

Now let us find unit rate for Eddy.

We have been given that Eddy has $60 and he is spending $2 per week, which means each next week Eddy will have $2 less than last week, therefore, unit rate for Eddy will -$2 per week.

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
