The difference of a number and 5 = n - 5
Twice that = 2(n - 5)
‘is’ is the equal sign, so the expression before is equal to 7.
Equation: 2(n - 5) = 7
Answer:
Factors of 6 are,6,3,2,1
and factors of 7 are, 7,1
Step-by-step explanation:
The common factors of 6 and 7 are 1, intersecting the two sets above.
In the intersection factors of 6 factors of 7 the greatest element is 1.
Therefore, the greatest common factor of 6 and 7 is 1.
Answer:
in one year the tofu will cost $3,16
In five years the tofu will cost $3,88
Answer:
The first option is the answer (k = +/- 2 square root of J)
Step-by-step explanation:
Since you need to leave k by itself, You multiply both sides by 4 which will leave you with 4J=k^2. To get rid of the square(^2), you need to square root both sides which will leave k by it self. So now you have 4J inside the square root = k. The last step is to take the square root of 4 (which is + or -2) and put it outside the square root sign, leaving J inside the square root.
