Answer:
x = 12
Step-by-step explanation:
7x=8x-12
take away the 7x from both sides
0=x-12
add 12 to each side
12=x
check it
7(12)=8(12)-12
84=96-12
84=84
18/36=x/280
36x=5040
x=140 ft.

Answer:
2x^2 + 11x - 6
b = 11
Step-by-step explanation:
To write the equation in standard form, use the distributive property to multiply. Then combine like terms.
(2x - 1)(x + 6)
2x^2 - x + 12x - 6
2x^2 + 11x - 6
Now written in the standard form of a quadratic ax^2 + bx + c, the value of b here is 11.
Answer:
a+b = 12
Step-by-step explanation:
There are 36 possible outcomes for rolling two dice. Let A be the number rolled by Abed and D be the number rolled by Dawn. The sample space, in the format [A,D], of all of the possibilities in which Dawn's number is larger is:
[5,6]
[4,5] [4,6]
[3.4] [3,5] [3.6]
[2,3] [2.4] [2,5] [2.6]
[1,2] [1,3] [1.4] [1,5] [1.6]
There are 15 ways out of 36 possible ways of Dawn getting the higher number. In the simplest form:
