Answer:
2(4+x)
Step-by-step explanation:
"Twice the sum of" tells us it will be the equation times two
"the sum of four and a number" is easy, thats 4 + x
The second number is x because the number is not specified so we need a place holder, x in this case, to tell us that the number is not given.
All this put together = twice the sum of four and a number, or <u>2(4+x)</u>
-5x-6.5>12
Add 6.5 to both sides...
-5x>18.5
Divide both sides by -5 and flip the sign...
x<-3.7
the correct answer is - 1/2
Answer:
210cm
Step-by-step explanation:
B=l•w
B=5•6
B=30
V=B•h
V=30•7
V=210
Put 1.12 on top and times regullarly you should get 1280.00
