Answer:
The answer is 29.25
Step-by-step explanation:
Using distributive property, the equation would be 3(9.75).
9.75*1+9.75*1+9.75*1=29.25
It looks like there’s a pattern going on here so i believe it would be B
(-7x)(9-2x)
-63x+14x
-49x is the answer
I'll show you a couple of examples, since all the exercises are to be done in the same way.
The point is that we can only sum two fractions if they have the same denominator. So, for example, we can sum
So, we first need to transform the two fractions so that they have the same denominators. A fraction can be transformed by multiplying both numerator and denominator by the same number. By doing so, you write another fraction with the same value as the original.
Let's deal with the first sum: we have 1/3 + 3/5. We transform the fraction as follows:
And now we can sum them:
