Answer:
3
Step-by-step explanation:
because if N = 6, then you will have to substitute the n to n and then do the order of operation. first it will be 6+3=9 and then 9*5=45. then you will do 7*6=42 and then subtract 45-42=3
Let x = hats she knitted
Less than means to subtract and it’s an order switcher so it would be
2x - 6 = 78
First step: Add six to both sides -6 + 6 = 0 6 + 78 = 84
2x - 6 = 78
+ 6. +6
2x = 84
Second step: Divide the coefficient on both sides, two is the coefficient
2x/2 = x
2/84 = 42
Therefore, the answer is x= 42
Answer:
4 3/8
Step-by-step explanation:
4 and 7/8 - 1/2 = 4 and 7/8 - 4/8 = 4 and 3/8 of a box more
9x² - 49
(3x)² - (7)²
= (3x + 7)(3x - 7)
This type of factoring is called Difference of Two Squares
where x² - y² = (x + y)(x - y)
Answer:
Step-by-step explanation:
4. 2 2/3 = 2 4/6
1/2 = 3/6
3/6 + 2 4/6 = 3 1/6
95÷3 1/6=30
5. 500,000
