We can think of this as an equality

5 Lawns = 8 Hours

If she needs 40 hours, you can multiply 8 hours by 5 to get 40, but now it's not balanced. So, you need to multiply 5 to the other side too so:

5 x (5) = 8 x (5)

Therefore she mows 25 Lawns in 40 Hours

If g(x) = 3x - 5, then g -1(x)=<br><br><br><br> 3x + 5
ludmilkaskok [199]

Hey!

-------------------------------------------------

This just shows to substitute all of x with -1.

g(-1) = 3(-1) - 5

g(-1) = -3 - 5

g(-1) = -8

-------------------------------------------------

Hence, the answer is -8!

-------------------------------------------------

Hope This Helped! Good Luck!

Answer: 225 square feet

Step-by-step explanation:

We find the area of the 4 triangle and the area of the rectangle and thereafter we add everything together.

Area of triangle 1 = 1/2 base × height

= 1/2 × 12 × 8

=96/2

=48

Area of triangle 2 = area of triangle 1= 48( because the opposite triangle are congruent so they have equal base and height)

Area of triangle 3 = 1/2×base×height

= 1/2 × 6 ×9.5

= 57/2

=28.5

Area of triangle 4=Area of triangle 3 = 57 (the opposite triangle are congruent and so they have the same base and height hence the same area)

Area of the rectangle = length×breadth

=12 × 6 =72

Total surface area = addition of all the areas of the triangles and the rectangle

Total surface area= 48+48+57+57+72 = 225

Therefore, the total surface area is 225 square feet

??????????????????????
Degger [83]

Answer:

The total golf balls Jack has now in terms of expression is as below

a = 3b + 6

Where a is total number of balls and b is number of balls in each bag.

Step-by-step explanation:

Solution:

let a be the total number of balls and b is the number of balls in each bag.

Number of bags is 3.

So total number of balls before the friend gave is 3\times b

Now the friend has given him 6 more golf balls then the total number of balls will become 3b + 6.

Therefore, the required expression is

a = 3b + 6
