2x2-6x= - 8
Simplify both sides
2x(2) = 4x
Combine like terms
4x + (-6x) =-8
-2x = -8
Divide each side by -2
X = 4
the age of this person is dead or 312
Answer:
0.60
Step-by-step explanation:
In the category of pets
22 students had a cat = P(C)
17 students had a dog = P(D)
9 students had both a dog and a cat = P(C and D)
The formula to find the Probability of two events =
P(C or D) = P(C) + P(D) - P(C and D)
P(cat or dog) = P(cat) + P( dog) - P(cat and dog)
P(cat or dog) = 22/50 + 17/50 - 9/50
P(cat or dog) = 0.44 + 0.34 - 0.18
P(cat or dog) = 0.60
The probability the student will have a dog or a cat is 0.60

Answer:
the third angle is 70 degrees
Step-by-step explanation:
an isosceles triangle has two equal angles and one other with a different angle value.
All angles add up to 180 degrees
therefore we can create the equation
180 = 55 + 55 + x
NB : x is the value of the third angle
180 = 110 + x
x = 180 - 110
x = 70
<u>the third angle is 70 degrees</u>
