6, 1.5, 10, 16, 80, and 2
Answer:
yes and
Step-by-step explanation:
Answer: Part A An equivalent expression of 4(a + 12) + 5(8) is 4a + 4(12) + 5(8)
or 4a + 48 + 40
Part B: using 15 in place of a, the Rodriguez family spent $148 on tickets.
Step-by-step explanation: We can use the distributive property to create equivalent expressions.
Part B: Substitute 15 in place of <em><u>a </u></em> and do the calculations
4(15 + 12) + 5(8)
60 + 48 + 40
148
Answer:
The two x-intercepts are (-1, 0) and (3, 0).
Step-by-step explanation:
Set each factor = to 0 and solve for x:
x + 1 = 0 => x = -1. One x-intercept is thus (-1, 0).
x - 3 = 0 => x = 3. The other x-intercept is (3, 0).
8/20(2/5) are boys
12/20(3/5) are girls
6/20(3/10) are girls with glasses
You have a 3/10 chance of the student is being a girl with glasses.
