Answer:
1) 42
2) 41
Step-by-step explanation:
1) 7 + x = 49
Subtract 7 from both sides.
x = 49 - 7 = 42
2) 5 + x + 3 = 49
Combine like terms.
x + 8 = 49
Subtract 8 from both sides.
x = 49 - 8 = 41
There is no x-intercept, the y-intercept is 3.75. The slope is 0.
For the first one, the answer is 2. You can only fold it vertically and horizontally. For the second one, the answer is O because any way you turn it, it still looks like O. I hope this helps!
Answer : The greatest number of red marbles is 24.
Explanation:
Let the number of red marbles be x
Let the number of blue marbles be y
Since we have given that sum of blue and red marbles is atmost 36
i.e. x+y ≤ 36 (Equation 1)
and we have also given that red marbles is twice of blue marbles .
i.e. x= 2y ( Equation 2)
By putting the value of x from( Equation 2) in ( Equation 1) ,
we have,
2y+y ≤ 36
⇒ 3y ≤ 36
⇒ y ≤
⇒ y≤ 12
Now, we put the value of y in Equation 1
x+ 12 ≤ 36
⇒ x ≤ 36-12
⇒ x ≤ 24
So the greatest number of red marbles are in the bags is 24 .
