Answer:
x=15
Step-by-step explanation:
165+x=180
x=180-165
x=15
Answer:
it is not a right triangle because 130 does not =121
Answer:
His error is adding 10 and 2/3 before multiplying by a(age of the tree)
Step-by-step explanation:
The sum of 10 and two-thirds of that tree's age, in years, is equal to 50.
Correct equation
Sum = addition (+)
two-thirds = 2/3
The tree's age = a
10 + 2/3a = 50
2/3a = 50 - 10
2/3a = 40
a = 40 ÷ 2/3
= 40 × 3/2
= 60
a = 60 years
Javier writes the equation
(10 + two-thirds) a = 50
(10 + 2/3)a = 50
(30+2/3)a = 50
32/3a = 50
a = 50 ÷ 32/3
= 50 × 3/32
= 150/32
a = 150/32
His error is adding 10 and 2/3 before multiplying by a(age of the tree)
Answer:
1.92
Step-by-step explanation:
mean ( or average ) = sum of values / the total number of values
so the sum of the values is counting each value
doing so we would get 46
we then add the number of values given which would be 24
so we have mean = sum of values / # of values
and we have sum of values = 46 and # of values = 24
so mean = 46/24 = about 1.92
The GCF of those three monomials is y².
