The third choice is very useful. It's valid because two things that are both equal to 'y' are equal to each other, and it can be easily solved to find 'x'.
Answer:
14x+8
Step-by-step explanation:
Answer:
you mulitple the two bottomz by the other number
example 3/4 and 2/8
8 is a common mulitple so 3/4 becomes 6/8 and now they have common denominators
Step-by-step explanation:
example 3/4 and 2/8
8 is a common mulitple so 3/4 becomes 6/8 and now they have common denominators
and the numerator gets multipled with the same number as the denominator
Answer:
Step-by-step explanation:
Let the number be x.
four times the number:
4x
If the exprression is increased by 1, it will become:
4x+1
If the value is between -7 and 13, the value of x will be within the range [-6, 12]
Equating the resulting expression to each end point.
At end point of -6
4x+1 = -6
4x = -6-1
4x = -7
x = -7/4
At the end point of 12:
4x+1 = 12
4x = 12-1
4x = 11
x = 11/4
Hence all the numbers will be within the range [-7/4, 11/4] or -7/4≤x≤11/4
