If you mean: -4+3+2s = 15 then s = 8
you do 2 + 2
22+22
2s-4 equals 2(s-2). You can find the answer by factoring two out of both numbers.
44 11 4 __2 2 lines go from 44 to 11 and 4 lines go from 4 to both 2s
If you mean: -4+3+2s = 15 then s = 8
2 + 2 + 2 + 2 = 8
Four 2s make 8, so 25% is your answer
you do 2 + 2
22+22
This is easy. Make two equations, and represent the sandwiches with s and the drink with d. you get: 2s+d=10 s+2d=8 After simplifying and taking away a variable, you figure out that each sandwich costs 4 dollars and each drink costs 2 dollars. (Heres the step by step algebra) 2s +dy = 10 s + 2d = 8 2s + d = 10 2s + 4d = 16 3d = 6 d = 2 2s + d = 10 2s + 2 = 10 2s = 8 s = 4 So, Sandwich = £4 Drink = £2
2, 4, 6, 8, 12, 14, 16
22/2 - 2
2, 4 8, 16, and 32.
All numbers in the 2s column on the multiplication table end in the even numbers 2, 4, 6, 8, or 0.
Assuming 34 is 3/4:Jane is 12To solve:S+4 = 3/4(J+4)(J-4) = 2(S-4)S = 3/4(J+4)-4J = 2S-4S=3/4(2S-4+4)-4S=3/4(2S)-4S=8J=2(8)-4=12
2s-4 equals 2(s-2). You can find the answer by factoring two out of both numbers.
