Rosa brought d drawings to an art show. after selling 17 of them, she had 22
left. identify the equation that represents this situation and the correct
solution

for me it’s

a)d+17=22; d=39

b)d+17=22; d=5

c)d-17=22; d=5

d)d-17=22; d=39

C) d - 17 = 22

Step-by-step explanation:

selling 17 means she had 17 less than what she brought

d - 17 = 22 means: 22 is 17 less than what she brought

Option D

ANSWER:

Rosa brought d drawings to an art show. The equation that represents this situation is d - 17 = 22; d = 39

SOLUTION:

Given, Rosa brought d drawings to an art show.  

After selling 17 of them, she had 22 left.

We have find the total drawings brought by rosa and the equation representing the situation.

Now, let us find the equation that represents the situation.

At first, she had d drawings.

Then she sold 17 drawings, so she has d – 17 drawings.

Finally she has 22 drawings, which means d – 17 = 22.

So the equation is d – 17 = 22.

From the above equation,

d = 22 + 17  = 39.

Hence, the correct option is d.

25, 37

Step-by-step explanation:

Let "a" and "b" be natural numbers.

Your friend tells you that 2 times the first number is 13 more than the second number.

2a = b + 13 [1]

She also tells you that the sum of the two numbers is 62.

a + b = 62

b = 62 - a [2]

We can replace [2] in [1],

2a = (62 - a) + 13

3a = 75

a = 25

From [2]

b = 62 - a = 62 - 25 = 37
