Answer:
x=4
y=-3
Step-by-step explanation:
3x+4y=0
2x+5y=7
Change 3x+4y=0 into y= -3/4x
so substitute for y
2x-15/4x=7
-1 3/4x = 7
x=-4
substitue x for y and get
-3/4 * 4
y=-3
Answer:
Lana can put 24 drops of bubble bath for her sister
Step-by-step explanation:
If package says to put in a drop of bubble bath for every half gallon of water in the bath tub.
If the bathtub can hold 12 gallons of water
There are 12÷1/2 gallon
=12×2/1
=24
It means there are 24 half gallons in the bathtub
If every half gallon of water requires a drop of the bubble bath
Then,
24 half gallons of water requires 24 drops of the bubble bath
The answer should be 2.5, because you are cutting the value that they gave you in half
You would start by 6÷3. This would tell you that for every proud of hamburger you pay $2.
Therefore multiply 10×2 and that equals 20.
Therefore, your answer is $20.
Answer:
Option 1. F F → T is the answer.
Step-by-step explanation:
In this question the given conditional statements are
3×2 = 5 then 6 < 0
We have to find the truth value of these conditional statements.
Since multiplication of 3×2 = 6 therefore the truth value of this statement is False.
For the statement 6<0 truth value is false because 6 is always greater than 0.
Now we know in two statements P → Q, if they follow the Implication rule then truth value is False only when P is true and Q is false otherwise in every condition the truth value is True.
Therefore F F → T illustrates the statements of the question.
