Answer:
4 cm
Step-by-step explanation:
area of a triangle = 1/2 * base * height
24 = 1/2 12 * height
height = 4 cm
Bobbie: x comic books
Kenny: 9 more comic books than Bobbie: x + 9
Together: 95 comic books
To write the equation that could be used to find the number of comic books they each have, we have to put it together:
x + (x + 9) = 95
x + x + 9 = 95
2 * x = 95 - 9
2 * x = 86 /2
x = 86 / 2
x = 43
Result: Bobbie has 43 comic books, Kenny has 52 comic books (43 + 9).
Answer: x= 1, 
Step-by-step explanation:
The quadratic equation is

and

So we just need to sub in the proper numbers from the equation given, in this case, it would result in

and

Once we get this we can either manually simplify or use a calculator, using a calculator would result in the answers
x= 1, 
Answer:
y=-2.5-5/4x and no it doesn't pass through (4,12)
Step-by-step explanation:
5x-4y=10
-5x +5x

/-4 /-4
y=-2.5-5/4x
Answer:
<h2>Check the explanation.</h2>
Step-by-step explanation:
Let, the total population is 1000.
The number of republicans are 26% that is 260, Democrats are 63% that is 630 and Independents are 11% of 1000, that is 110.
20% of 260 =
Republicans favor some type of corporate tax reform.
51% of 630 =
.
29% of 110 =
.
Total number of people, who favor some type of corporate tax is (52 + 321.3 + 31.9) = 404.2 ≅404.
The required probability is
.
