Two runners are saving money to attend a marathon. The
first runner has $112 in savings, received a $45 gift from a
friend, and will save $25 each month. The second runner
has $50 in savings and will save $60 each month
Which equation can be us
. months it will take for both
amount of money?
112 - 25m + 45 = 50 -
112 + 25 + 45m = 50m
112 + 25 – 45m = -50m
0 112 + 25m + 45 = 50 + 60

all but the second one

step-by-step explanation:

cuz that one goes over 180

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a

step-by-step explanation:

mark brainliest!

none of these

step-by-step explanation:

23 + 34 add up to 57 so just inform the teacher of this really stupid mistake
