Answer:
B
Step-by-step explanation:
We have 2 inequalities, so we will obtain at maximum 2 ranges for x
5x-29>-34. Lets solve for x, pass -29 to the other side
5x>-34+29, this gives 5x>-5, from that we obtain the first range x>-1
(-1, inf)
The second one is similar
2x+31<29, solving for x you have the following: 2x>-2 <(note that we have to reverse the < sign since the "-" sign that appears when performing the subtraction -31+29=-2) thus you have x>-1, our second range is (-1, inf)
Comparing the two ranges... we have x>-1 repeating, thus, is enough to say that we have only one range, x>-1
Answer:
d=rt
r=420 per hr, 3 hrs = 420/3= 140
t=1
d=140×1=140miles
Answer:
? = 49
Step-by-step explanation:
To solve this we just need to understand that when A=1, B=7. So when the side for a is 7 that is basically multiplying A by 7 so we have to do the same to the B side. So when the B side is multiplied by 7 it would be 7*7 =49 so the ? is equal to 49 when that similar side is equal to 7.
This is all based on the fact that the two triangles must be similar triangles.
