When multiplying with fractions you can multiply the top and the bottom independantly
5*3 = 15
1*4 = 4
so 5 * (3/4) = 15/4
Answer:
We have a + b as;
2 + 3 = 5
Step-by-step explanation:
Here, we want go get the value of a and b
from the second equation, we can get an expression for b
We have this as;
7a - b = 11
Thus,
b = 7a - 11
Now, from here, we can substitute the value of b into the first equation
We have this as;
5a + 4(7a - 11) = 22
5a + 28a -44 = 22
33a = 22 + 44
33a = 66
a = 66/33
a = 2
Recall;
b = 7a - 11
substituting the value of a from above;
b = 7(2) - 11
b = 14 - 11
b = 3
Answer:
17/3
Step-by-step explanation:
You would need to convert 5 into a fraction with the denominator 3, so 5 = 15/3. 15/3 + 2/3 = 17/3
None of them because they are not in order
