Answer:
3
Step-by-step explanation:
So, since they are similar, so 9:12 and 15:x
to get to 12, you have to multiply 9 by 4/3. so multiply 15 by 4/3 to get your answer, which is 20.
Answer:
c
Step-by-step explanation:
Answer:
y = 3x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 3, thus
y = 3x + c ← is the partial equation of the line
To find c substitute (1, 4) into the partial equation
4 = 3 + c ⇒ c = 4 - 3 = 1
y = 3x + 1 ← equation of line

Answer:
255
Step-by-step explanation:
The factorization of 50 is 2×5×5. The sum of these factors is 12, so these are the digits of interest. Arranged with 5 as the leading digit, the number is not less than 500, so 2 must be the leading digit.
The mystery number is 255.
