Answer: A) a number is negative
Step-by-step explanation:
A conditional statement is written as:
If P, then Q.
Where P is the hypothesis and Q the conclusion.
In this case, we have:
If a number is negative, then the number is less than zero.
then we have:
P = a number is negative.
Q = the number is less than zero.
Then the hypothesis will be "a number is negative"
The correct option is A.
Answer:
A
Step-by-step explanation:
they are equal on the same side
35kg - a mass of sugar syrup
30% of 35kg it's a mass of sugar
30% = 30 : 100 = 0.3
30% of 35kg = 0.3 · 35kg = 10.5kg - a mass of sugar
Add xkg water. Then we have (35 + x)kg of sugar syrup and still 10.5kg of sugar.
10.5kg is 25% of (35 + x)kg .
(35 + x) -- 100%
10.5 -- 25% <em>multiply both sides by 4</em>
42 -- 100%
Therefore we have the equation:
35 + x = 42 <em>subtract 35 from both sides</em>
x = 7
<h3>Answer: We should add 7kg of water.</h3>
