6 - 2 x 1
= 6 - 2
= 4
We have to use the PEDMAS method in solving all kinds of calculation expression.
P = Parentheses (or brackets)
E = Exponents (or Index)
D = Division
M = Multiplication
A = Addition
S = Subtraction
Answer:
The answer is -2.
Step-by-step explanation:
7w + 18 = 10w + 24
7w = 10w + 6
-3w = 6
w = -2

Answer:
(x, y) = (1, 7.5)
Step-by-step explanation:
Solve the first equation for y, then substitute into the second equation.
y = 8 -1/2x . . . . . subtract 1/2x
2(8 -1/2x) = x +14
16 -x = x + 14 . . .eliminate parentheses
2 = 2x . . . . . . . add x-14
1 = x . . . . . . . . divide by 2
y = 8 -1/2(1) = 7 1/2
The solution is (x, y) = (1, 7 1/2).

<em>Alternate solution</em>
Type the equations into a graphing calculator and let it show you the solution.
Answer:It's an arithmetic sequence with a common difference, d, = 4
A1 = 8
A2 = 8+4 = 12
A3 = 12+4 = 16 = 8+4(3-1) = 8+4(2) = 8+8
AN = A1 + d(N-1)
AN = 8 +4(N-1) = the Nth term in the sequence
