Before adding dissimilar fractions (fractions with different denominator), you have to make the fractions similar first. To make the fractions similar, find the Least Common Multiple of the denominator. In this case, the LCM is 10. Then rewrite the fractions using the LCM as the denominator.
9/10 = 9/10; 4/5 = 8/10
You can now proceed with addition -
9/10 + 8/10 = 17/10 or 1 7/10

Step-by-step explanation: 7829219882 / 278892828891271289289
depends on the situation like this one at times :)
Number 1 is x=8!!
2 is pretty confusing so I hope someone else can answer two as I have answered 1!
T=90-Z
Because 9 solved correctly*10 points per question answered correctly=90 and each incorrect question is a point lost
7 is the most common in this expression.
therefore to factorise, you will choose the most common factor.
the answer will be -7(r+5x)
