Answer:
Step-by-step explanation:
The reciprocal would be 9/7 because a reciprocal is when you flip a fraction and put the denominator as the numerator and vice versa.
The answer is 68.
To solve 2 more tens than 40, you add 20 to 40, which is 60.
To solve for the same number of ones as 18, then it would only be 68.
Hope this helps!!
y = 8 -2x
x + 2 (8 - 2x) = 1
x + 16 - 4x = 1
x - 4x = -15
-3x = -15
x = 5
If x = 5, then we can substitute in...
5 + 2y = 1
2y = -4
y = -2
Now let us check that by substituting those values in to the equation
2x + y = 8
2 (5) + (-2) = 8
That is correct so we have the right values for x and y/
531,441
solution:
Multiply.
(9²)³
Multiply 9².
9 x 9
9² the 2 means multiply to itself.
so 9x9 is equal to (81)³
Now multiply it again
81 x 81 x 81
= 531,441
