Answer:
6x = 9
Step-by-step explanation:
4x-5y = 12
2x+5y = -3
Add the equations together
4x-5y = 12
2x+5y = -3
-------------------
6x + 0y = 9
6x = 9
Answer: 9/55
P(1st = red and 2nd = blue)
= (3/11) x (6/10)
= 18/110
= 9/55
To find the probability of something happening,
= (number of desired outcomes) / (total number of outcomes)
If you are finding the probability of more than one thing happening at the same time, you multiply the probability of both things happening together
<span>1- What is the distance formula?
distance = </span>√(x2-x1)² + (y2-y1)²<span>
2- plug in the correct values from the problem, write the diatance formula with substituted values
</span>distance = √(4-(-3))² + (-6-5)²
<span>
3- simplify the expression, what is the distance between the two points?
distance = </span>√170 = 13.04
Answer:
A = 78.5 cm²
Step-by-step explanation:
Area = π · radius²
if diameter is 10 then radius is 5
A = 5²·π
A = 25 × 3.14
A = 78.5 cm²
