Answer:
Red
Step-by-step explanation:
To solve this we can use substitution.
We know that y=4-x, so we can substitute "4-x" into anywhere that y appears in the first equation.
4-x=3x-8
Now we can move the variables to one side and the numbers to the other.
We can do that by adding x to both sides.
4=3x-8+x
Now, let's add 8 to both sides.
4+8=3x+x
Combine like terms.
12=4x
x=3
Now, we can plug that back into the equation to find y.
y=3(3)-8
y=8
y=1
So our answer is (3,1)
Answer:
16 pounds.
Step-by-step explanation:
As you said, objects weigh 6 times more than what they weigh on the moon. Therefore, the robot originally weighing 96 pounds will be reduced to 16 pounds.
16*6=96. (Original Weight)
96/6=16. (Weight after being on the moon.)
Answer:
C.
Step-by-step explanation:
-3 7/8 rounds down to -4
4.63 rounds up to 5
-4 x 6 + 5
-24 + 5
-19
her answer (-19.14) also rounds to -19
So yes, it is reasonable and the correct response is C.
3x*5x-2=4-2x*1
15x-2=4-2x
13x=2
x=6.5
