What is x if x-7 equals 13?
x - 7 = 13 Therefore, x = 13 + 7 x = 20
If 5x - 17 -x plus 7 then x?
5x - 17 = x + 7 4x - 17 = 7 4x = 24 x = 6 Check it. 30 - 17 = 13 It checks.
How do you find the least common denominator in a fraction?
It's the same process as finding the least common multiple. Example: 7/30 + 13/42 Factor them. 2 x 3 x 5 = 30 2 x 3 x 7 = 42 Combine the factors, eliminating duplicates. 2 x 3 x 5 x 7 = 210, the LCM Since 210 is the lowest common denominator, we can proceed to add them. 7/30 = 49/210 13/42 = 65/210 7/30 + 13/42 = 114/210 or 19/35 in lowest terms.
What does 7 X 13 equal?
7 x 13 = 9113*7=91
What is the answer to x - 7 - 4 equals 13?
x - 7 - 4 = 13 (-7 - 4 = -13) x - 11 = 13 add 11 to both sides x = 24
What is x if x-7 equals 13?
x - 7 = 13 Therefore, x = 13 + 7 x = 20

What does 7 X 13 equal?
7 x 13 = 9113*7=91
What is equal to the expression of 13 x 15 plus 13 x 7?
13 x (15 + 7) ie 13 x 22 = 286 or 13 x 15 = 195, 13 x 7 = 91, 195 + 91 = 286
What is the answer to x - 7 - 4 equals 13?
x - 7 - 4 = 13 (-7 - 4 = -13) x - 11 = 13 add 11 to both sides x = 24
What does 30 x 13 equal?
30*13 = 390
What is the prime factorization of 3185?
3185 = 5 x 7 x 7 x 13 = 5 x 7^2 x 13
What is 7 x 30?
7 X 30 equals 210.
What is x-7- 6?
-13
What is a factor tree of 728?
728 13 x 56 13 x (7x8) 13 x (7 x (2x4)) 13 x (7 x (2 x (2x2))) Since 2, 7, and 13 are prime numbers, the factor tree is complete.
