Answer:
Number : 42
Step-by-step explanation:
This number will be a two - digit number, and hence we can say that it is yz. The ratio of the units digit to the tens digit is given by 1 / 2, so z / y = 1 / 2.
In addition the tens digit is 2 more than the units digit, so y = z + 2. We therefore have the following system of equations,
y = z + 2,
z / y = 1 / 2
Substituting the first equation into the second we receive z / z + 2 = 1 / 2. Using this we can solve for z.
z / z + 2 = 1 / 2 ( Cross - Multiply )
z + 2 = 2z, z = 2
And knowing z we can solve for y. y = z + 2 = 2 + 2 = 4. Therefore our number is 42.
C = 5/9 (F - 32)
F = (9/5)C + 32
F = (9/5)(-40) + 32 = -40
F = (9/5)(125) + 32 = 257
Commutative Property of Addition
The pattern is increasing by 10 then a ding 1 to the next number. Hope this helps! :)
A C and F those would be the correct answers girlie
