The equation would be d - 19 = 73. So the zoologist would take the number of deer recorded and subtract it from 19 (since it said 19 fewer deer) and the answer would be 73 (because that is how many deer were recorded a year later. I hope this helps!

<h2>Note this is step not a awnser because not all evidence was applied!</h2>

Step-by-step explanation:

24-small

12-medium

5-large

then what you want to do is find how many are there together im gonna say small has 12 medium has 16 and large has 20

Next you want to subtracts 3 small boxes cause of defects 24-3=21

Then, you want to multiply what your numbers are.

21*12=252

12*12=144

5*20=100

Then add

252+144+100=496

The local skating rink pays Mary a fixed rate per pupil plus a base amount to work as a skating instructor. She earns $90 for
baherus [9]

Answer:The expressions for the payment made to Mary are,

        (Monday)      90 = 15m + b

        (Tuesday)     62 = 8m + b

where m and b are the fee per student and the base fee, respectively. Solving for m and b, the values are 4 and 30.

The equation that represents Mary's earning is

                                   y = 4x + 30

For 20 students,

                                   y = 4(20) + 30 = 110

For Lisa's earnings,

                                    y = 8x + 15

Substituting 20,

                                   y  =8(20) + 15 = 175

Thus, Lisa would earn more than Mary by $65.

What is the LCM of 12,30 and 42
Hoochie [10]

Answer:

420

Step-by-step explanation:

We can find the prime factors of each of the numbers first before finding their LCM.

12: <em>2</em> × 2 × <u>3</u>

30: <em>2</em> × <u>3</u> × 5

42: <em>2</em> × <u>3</u> × 7

To find the LCM, we need to see if they are any common prime factors between all three numbers. The common prime factors are <em>2</em> and <u>3</u>. Then, we multiply 2 and 3 with the remaining outstanding factors, which are 2, 5, and 7.

LCM: <em>2</em> × 2 × <u>3</u> × 5 × 7 = 420
