Answer:
Equivalent expressions are expressions which are equal. This means they simplify to the same expression. Simplify the two expressions -1.3x - (-8.9x) = 7.6x and -1.3 + (-8.9X) = -10.2x.
Then simplify each option to determine if it is equal -1.3x - (-8.9x), -1.3 + (-8.9X) or neither:
−1.3x−8.9x = -10.2x. This is equivalent to -1.3 + (-8.9X) .
8.9x+(−1.3x) = 7.6x This is equivalent to -1.3x - (-8.9x) .
−8.9x+(−1.3x) = -10.2x This is equivalent to -1.3 + (-8.9X) .
8.9x−(−1.3x) = 10.2x Neither
−1.3x+8.9x = 7.6x This is equivalent to -1.3x - (-8.9x) .
−8.9x+1.3x = -7.6x Neither
Step-by-step explanation:
The time to complete 2 levels is (c) 60 minutes
<h3>How to determine the time to complete 2 levels?</h3>
The table of values is given as
Number of Levels Time (hours)
2 ?
3 1.5
Express the blank (?) with y
Number of Levels Time (hours)
2 y
3 1.5
The ordered pairs from the table are
(x, y) = (2, y) and (3, 15)
The table shows the proportional relationship
This means that the equation can be represented as
y = Y/X * x
Where
(x, y) = (2, y)
(X, Y) = (3, 1.5)
So, we have
y = 1.5/3 * 2
Evaluate the quotient
y = 0.5 * 2
This gives
y = 1 hour
Convert to minutes
y = 60 minutes
Hence, the time is 60 minutes

Answer:
It's 10 times larger.
Step-by-step explanation:
If you just have 500,000, and the other one is 50,000, That means 50,000 x 10 is 500,000.
