Answer:

Her mother will donate $11.20

Step-by-step explanation:

  • $0.40 every 0.75 miles.
  • 21 miles biked.

Step 1: Figure out how many 0.75 increments are in 21 miles.

21 ÷ 0.75 = 28

  • There are 28 increments of 0.75 in 21 miles.

Step 2: Multiply 28 by $0.40

28 * $0.40 = $11.20

Andrews [41]

Step-by-step explanation:

Step one:

Johny Deposited 50000 rupees,

Jaleel 40000 and

Jaleel 20000 rupees

total deposits = 110,000

They got 3300 rupees as a profit in a month

Johny's investment in percent

50000/110000= 0.45%

Jaleel's investment in percent

40000/110000= 0.36%

Jaleel's(2) investment in percent

50000/110000= 0.18%

They will get

Johny =0.45*33000= 1485 rupees

Jaleel= 0.36*3300= 1188 rupees

Jaleel(2)= 0.18*3300=594 rupees

What is the solution to the system of equations below?
disa [49]

The solution to the system of equation are x=2, y=0, z=6

<h3>System of equations</h3>

System of equations are equations that contains unknown variables.


Given the equations

3x+y+2z=8

8y+6z=36

12y+2z=12

From equation 2 and 3

8y+6z=36 * 1

12y+2z=12 * 3

______________

8y+6z=36

36y+6z= 36

Subtract

8y - 36y = 36 - 36

-28y =0

y = 0

Substitute y = 0 into equation 2

8(0)+6z=36

6z = 36

z = 6

From equation 1

3x+y+2z =8

3x + 0 + 2(6) = 8

3x = 8 - 12

3x = 6

x = 2

Hence the solution to the system of equation are x=2, y=0, z=6
