Answer: Well since the ratio is 9:7 for red to blue well transfer that first by finding out the blue if there are 117 xc=9:7x13 would be 117 red and 7x13=91 blue so the new ratio is 117:91.
So now we add which I'm sure you can do,
117
+
91

Answer:
He needs to get up at 6:30 am.
Step-by-step explanation:
- convert all time to minutes (easier to add times and you can later convert back to hours)
- add all the minutes up
- divide by 60
- subtract the quotient from 9 (since that is the time he needs to get there)
- you should get 6.5 which is 6:30
Answer:
x is 7.5 so the answer is D
Step-by-step explanation:
Since the triangles are similar, you can flip the 1st one to match the 2nd.
Now you can write
16/12=10/x
(the 9 is irrelevant)
now cross multiply to solve for x
12x10=120
120/16=7.5
x is 7.5
Is this math? I'm sorry I don't get what formula I'm supposed to rewrite or -
