Answer: x = -5
Step-by-step explanation:
-8 (x + 5) = -3x - 7 + x - 3
First, we use distributive property
-8x - 40 = -3x - 7 + x - 3
Then, we combine like terms.
-3x + x = -2x
-7 + -3 = -10
-8x - 40 = -2x - 10
Add 10 to each side
-8x - 30 = -2x
Add 8x to each side
-30 = 6x
Divide each side by 6
-5 = x
Step-by-step explanation:
13x + 15 = 19x - 9 ( being opposite sides of parallelogram)
19x - 13x = 15 + 9
6x = 24
x = 24 / 6
x = 4
4y + 7° + 10y - 37° = 180° {being co-interior angles }
14y = 180° - 7° + 37°
14y = 210°
y = 210°/ 14
y = 15°

Answer:
we need to see a graph
Step-by-step explanation:
B. A smaller percentage of second-lunch students (38%) eat outside.
Answer:
If you take into account all probabilities, and work on a strategy, rather than individual guesses, you can increase the probability.
Here are the possible outcomes:
BBB
BBR
BRB
BRR
RBB
RBR
RRB
RRR
If you use the strategy:
If a person sees a blue and a red, they pass;
If a person sees a blue and a blue, they guess red;
If a person sees a red and a red, they guess blue;
The probability comes out like this:
(B=blue, R=red, P=pass)
actual guess correct?
BBB RRR no
BBR PPR yes
BRB PRP yes
BRR BPP yes
RBB RPP yes
RBR PBP yes
RRB PPB yes
RRR BBB no
As you can see, this is a 6/8, or 75% chance of being correct.
