Answer:

k = P - m - n

Step-by-step explanation:

The question is asking you to rearrange the equation so that k is alone on one side.

P = k + m + n

P - k = (k + m + n) - k

P - k = m + n

(P - k) - P = m + n - P

-k = m + n - P

-1(-k) = -1 (m + n - P)

k = -m - n + P

The equation is completely simplified so this is your answer.

3/4 picked apples. If 120 students picked apples, how many picked bananas
Oxana [17]

Answer:

40 students picked bananas

Step-by-step explanation:

3/4 picked apples    

1 - 3/4 = 1/4 picked bananas

3/4x = 120

Multiply both sides of the equation by 4/3

4/3 * (3/4x) = 120/1 * (4/3)

x = 480/3

x = 160

                                               Total of 160 students

                                               /                                   \

                                   120 = apples                  160 - 120 = 40 = bananas

40 students picked bananas

Hope this helps :)

Mary throws a plastic disc to her friend, which her friend catches six seconds after Mary throws it. The table shows the height
natta225 [31]
Unfortunately, there is no given table. However, assuming no air resistance, the projectile moves in constant acceleration in the y-axis, while constant velocity in the x-axis. If the total time of flight is 6 seconds, then at 3 seconds the reaches its maximum height. Also, there is no given initial velocity, which means any useful calculation is impossible.

A doctor ordered 300 ml of a 10% solution,but the pharmacy only has 5% and 25% solutions. How many millimeters of each solution
NARA [144]

Answer:

We have 5% and 25% solutions and we need 300 ml of 10%.

Setting up 2 equations:

A) x + y = 300

B) .05 x + .25 y = (.10 * 300)  Multiplying A) by -.25

A) -.25x -.25y = -75  Then adding this to B) we get

-.20 x = -45

x = 225 ml .05% and we use 75 ml of 25%
