belka [17]

Q+B=13. When B+3=0

You have 2 separate equations.

First solve the 2nd equation for B:

B +3 = 0

Subtract 3 from both sides:

B +3 - 3 = 0-3

Simplify:

B = -3


Now we have a value for B, we can replace b with -3 in the first equation and solve for Q:


Q + -3 = 13

Add 3 to each side:

Q + -3 + 3 = 13+3

Simplify:

Q = 16


So you have Q = 16 and B = -3

Find the area and perimeter of the shaded figure
puteri [66]

Answer:

Area - 6 unit^2   Perimeter - 10 units

Step-by-step explanation:

The shaded figure is 3 units long and 2 units high.

L = 3  W = 2

A = LW

A = 3 x 2 = 6 unit^2

Perimeter = 2L + 2W

P = 2(3) + 2(2)

P = 6 + 4 = 10 units

What is the probability that a standard number cube will show a two, five, or six when it is rolled?
tia_tia [17]

Answer:

p=0.5

Step-by-step explanation:

A standard die has six numbers (1 through 6). That means there is a 1/6 probability of rolling any one number. There is a 3/6 probability of rolling one of the selected numbers which simplifies to 1/2 or 0.50
