Step-by-step explanation:
First, let us find the magic sum in each row/column/diagonal.
Sum of numbers from 1 to 9 = 45.
45 divide by 3 rows = 15 each row.
The magic sum is 15.
For the diagonals, we have:
8 + 5 + x = Magic sum = 15,
6 + 5 + y = Magic sum = 15.
Therefore x = 2 and y = 4.

180 - 94 = 86
So all the inside angles of a triangle = 180
180 - 86 - 60 = 34
34/2 = 17
Answer:
it's answer is 17
Step-by-step explanation:
we know exterior angle of a triangle is equal to the sum of two opposite interior angles. So,
2x + 60° = 94°
2x = 94° - 60°
2x = 34°
x = 34° /2
x = 17°

The answer is A) (3.1, 2.2)
Answer:
A
Step-by-step explanation:
Given the 2 equations
y = 2x - 4 → (1)
2x + 4y = 15 → (2)
Substitute y = 2x - 4 into (2)
2x + 4(2x - 4) = 15 ← distribute and simplify left side
2x + 8x - 16 = 15
10x - 16 = 15 ( add 16 to both sides )
10x = 31 ( divide both sides by 10 )
x = 3.1
Substitute x = 3.1 into (1) and evaluate for y
y = 2(3.1) - 4 = 6.2 - 4 = 2.2
solution is (3.1, 2.2 ) → A

Luna entered a raffle for a new pair of running shoes. She purchased 20 tickets and was told that she had a 20% chance of winning. How many tickets were sold? P (Luna winning) = StartFraction Number of tickets purchased over Total number of tickets sold EndFraction. 20 percent = StartFraction 20 over x EndFraction. One-fifth = StartFraction 20 over x EndFraction. x = tickets
Answers
Answer:
100 ticketsStep-by-step explanation:
Probability of winning = amount of tickets purchased/Total number of tickets
20% = 20/total number of tickets
20/100 = 20/total number of tickets
cross multiply
20 * total number of tickets = 20 * 100
20 * total number of tickets = 100
total number of tickets sold = 100 tickets
Answer:
100 tickets

What is the next term of the arithmetic sequence? -3,0,3,6,9,−3,0,3,6,9,minus, 3, comma, 0, comma, 3, comma, 6, comma, 9, comma
Answers
Answer:
12
Step-by-step explanation:
Given the arithmetic sequence :
-3,0,3,6,9
Using the relation :
Tn = a + (n- 1) d
d = common difference = t2 - t1 = 0 - (-3) = 3
The next term = 6th term ; n = 6
a = first term
T6 = - 3 + (6 - 1)3
T6 = - 3 + (5)3
T6 = - 3 + 15
T6 = 12
This formula gives the yearly depreciation D for
an item in terms of its cost C, its salvage value
S, and the number of years 71. Solve the
equation below for C.
C-S
De
Answers
Answer:
C = 71D + S
Step-by-step explanation:
The computation of the equation for C is as follows:
Given that
Yearly Depreciation = D
Cost = C
Salvage value = S
Number of years = 71
Based on the above information
The formula for the yearly depreciation i.e. D is
D = (C - S) ÷ 71
71D = C - S
71D + S = C
So, the equation would be
C = 71D + S
