Answer:
-2 1/2
Step-by-step explanation:
The first thing to do here is turn 8 3/4 and -3 1/2 into fractions(we will convert to mixed number at the end). So you get: 35/4 and -7/2.
That gives you (35/4)/(-7/2).
Then you use keep change flip to simplify this.
(35/4) * -2/7 = 2.5
2.5 as a mixed number is:
-2 1/2
Answer:
−40+2n=−4n+8
−40+2n+40=−4n+8+40
2n=−4n+48
2n+4n=−4n+48+4n
6n=48
answer: n=8
Step-by-step explanation:
Answer:
speed = 15cm/s
Step-by-step explanation:
To find the speed of the ant, we take the distance (30cm) and divide by the time (2s)
speed = 30cm/2s = 15 cm/s
4x+6+3=17
4x+9(add the 6 and 3)=17
4x=8(subtract 9 from each side 4x+9-9=17-9)
x=2(divide each side by 4, 4x/4=8/4)
2 is the final answer.
You can check your work...
4(2)+6+3=17
8+6+3=17
14+3=17
17=17
So this is correct!!! Hope this helps you.
Answer:
<em>1. 21, 22</em>
<em>2.29,30</em>
Step-by-step explanation:
1. m+4>24
subtract both sides by 4
m>20
Two values that are greater than 20 are 21 and 22.
2. 7<x/4
multiply both sides by 4
28<x
Two values that are greater than 28 are 29 and 30.
