The answer would be 101
Steps:
2+8=10
10x10=100 (because of the exponent)
100+1=101
Answer:
3/5
Step-by-step explanation:
60% means 60 out of 100. For example if you get 60 marks in an exam of 100 marks. This means you got 60% marks.
Which is 60/100. This fraction can further be reduced to 6/10 [divide both numerator and denominator by 10)
6/10 = 3/5 [divide both numerator and denominator by 2)
So, the reduced form of 60% =3/5
Z=-3 is the correct answer. Use math papa if you need help with the steps on how we got z=-3
We can factor by grouping. To do so, we multiply the leading coefficient with the constant at the end. In other words, a times c (ax^2 + bx + c).
15*-4 = -60
Now we need to split the b term into two pieces that multiply to -60 and add to 4.
-6 and 10 will work.
Now group one part of b with the 15x^2 and the other part with -4.
(15x^2 + 10x) + (-6x - 4)
Now factor both terms.
5x(3x+2) - 2(3x+2)
3x+2 is one of our factors and 5x-2 is the other.
(3x+2)(5x-2)=0
Now just find the zeros.
3x+2 = 0
3x = -2
x = -2/3
And
5x-2 = 0
5x = 2
x = 2/5
So the answer is x = -2/3 and x = 2/5
