Answer:
Yes
Step-by-step explanation:
We know this because the proportion can be used to find another answer.
Example:
How many feet did the elevator ascend in 0.25 minutes?
750 x
---------- = ----------
1 0.25
750(0.25) = 1x
187.5 = x

Answer:
£910
Step-by-step explanation:
let 3x and 7x be the initial amounts in their accounts, then after alterations
Terry has 3x + 220
Faye has 7x - 300
After these changes the amounts are equal, hence
7x - 300 = 3x + 220 ( subtract 3x from both sides )
4x - 300 = 220 ( add 300 to both sides )
4x = 520 ( divide both sides by 4 )
x = 130
Faye initially had 7 × £130 = £910 in her account
Answer:
42
Step-by-step explanation:
Let the number be "x"
We translate the word equation to algebraic equation.
First,
subtract 6 from me, so we have:
x - 6
Now,
Multiply by 2, so we have:
2(x-6)
Now,
Subtract 40, then divide by 4:
Now, you get "8", so equate this to 8, we get:
We now solve using algebra:
The number is 42
The answer = 6.3 × 10-2
(scientific notation)
= 6.3e-2
(scientific e notation)
= 63 × 10-3
(engineering notation)
(thousandth; prefix milli- (m))
= 0.063
