part A is just simple multiplication
since there are 2 6 sided number cubes there are 36 possible outcomes(6 sides *6 sides)

Part B is a little trickier. First off, you must find how to get seven.
1. 1+6 and 6+1

2. 2+5 and 5+2

3.3+4 and 4+3

therefore there are six combinations

you put that number over the total combos and get 6/36 or 1/6.

Hope this helps!

8.A For this, we can start with the first roll being 1, and then writing all the possibilities for the second roll. Then do the same for 2,3,4,5&6.

(1,1) (1,2) (1,3) (1,4) (1,5) (1,6) (2,1) (2,2) (2,3) (2,4) (2,5) (2,6) (3,1) (3,2) (3,3) (3,4) (3,5) (3,6) (4,1) (4,2) (4,3) (4,4) (4,5) (4,6) (5,1) (5,2) (5,3) (5,4) (5,5) (5,6) (6,1) (6,2) (6,3) (6,4) (6,5) (6,6)

8.B So lets look at the possibilities we wrote and see how many have a sum of 7.
(1,1) (1,2) (1,3) (1,4) (1,5) (1,6) (2,1) (2,2) (2,3) (2,4) (2,5) (2,6) (3,1) (3,2) (3,3) (3,4) (3,5) (3,6) (4,1) (4,2) (4,3) (4,4) (4,5) (4,6) (5,1) (5,2) (5,3) (5,4) (5,5) (5,6) (6,1) (6,2) (6,3) (6,4) (6,5) (6,6)

So out of 36 possibilities, 6 of them have a sum of seven
P(sum of 7)=6/36 simplify to 1/6

Quick help fast pleaseeeeee

Answer:

No.

Step-by-step explanation:

I am not exactly sure, but you can't divide <em>x and y, </em>which would already make the question null and void. The simplest form would be the form it is in right now.

Solve the system for (y) x+5y =-4; -x+5y=-16
kotykmax [81]

Answer:

x - 5y= -4 (equ...1)

-x + 5y=-16 (equ...2)

From equ... 1

x= -4 + 5y (equ... 3)

Substitute equ...3 into equ...2

-4 + 5y + 5y=-16

-4 + 10y=-16

Collect like terms

10y=-16 + 4

10y=-12

Divide both side by 10

y= -12/10 or -1.2

Substitute y= -1.2

x=-4 + 5y

x=-4 + 5(-1.2)

x=-4 - 6

x= -10

Hence,x= -10,y=-1.2 or-12/10

Kendra charges $11 to shovel a driveway. She shoveled 4 driveways on Saturday and then some more on Sunday. She made $143 for th
olya-2409 [2.1K]
For this case, the first thing we must do is define a variable.
 We have then:
 x: amount of driveways shoveled on Sunday
 y: total amount
 We now write the equation that models the problem:
 y = 11x + 44&#10;
 She made $ 143 for the weekend:
 143 = 11x + 44&#10;
 From here, we clear the value of x:
 11x = 143 - 44&#10;&#10;x = 99/11&#10;&#10;x = 9
 Answer:
 
She shoveled 9 driveways on Sunday

What is the area of a circle with a radius of 7 cm? (Use 3.14 for pi and round to the nearest tenth.)
vitfil [10]
Salutations!

Radius = 7cm

Area of circle = \pi r^2

                      = 3.14*7*7

                      = 153.94 cm^2

153.94 rounded to the nearest tenth = 153.9cm^2

Hope I helped (:

Have a great day!
