We are given the expression
5⁹ x 5³
We can solve this using the rule of exponents which is
a^n x a^m = a^(a + m)
Therefore, the answer is
to keep the base and add the exponents
5⁵⁺³ = 5⁸<span />
Ratio of apples to strawberries in Angie's salad
= 4:5
= 36:45 <em>(because we multiplied both numerator and denominator by 9, to get the same denominator as the other ratio)</em>
Ratio of apples to strawberries in Salim's salad
= 7:9
= 35:45 <em>(because we multiplied both numerator and denominator by </em><em>5</em><em>, to get the same denominator as the other ratio)</em>
36:45 ≠ 35:45
So, ratio of apples to strawberries in Angie's salad ≠ ratio of apples to strawberries in Salim's salad.
36:45 > 35:45
So, ratio of apples to strawberries in Angie's salad < ratio of apples to strawberries in Salim's salad.
Solving a polynomial inequation
Solving the following inequation:
(x - 8) (x + 1) > 0
We are going to find the sign both parts of the multiplication,
(x - 8) and (x + 1), have when
x < - 8
-8 < x < 1
1 < x
Then we know (x - 8) (x + 1) > 0 whenever (x - 8) (x + 1) is positive
We can see in the figure (x - 8) (x + 1) is positive when x < -8 and x > 1
Then
Answer:B
2/3 x + 15 = 17
2/3 x = 17 - 15
2/3 x = 2
x = 2 / (2/3)
2/1 * 3/2 = 6/2 = 3
x = 3
