Punctuation mark is another word for parentheses or brackets.
-2w+14+10w=348w=20w=2.5
It's 2+(-34)=-10 So put the parentheses around the -34.
(-2)^3 equals -2 times -2 times -2 which equals -8
The parentheses would be placed thus: 27 - (49 / 7 + 12) = 8
57 - (24 plus 15) = 18
No solution
8- (2x3x9)
Each of these factor pairs (multiply the numbers in parentheses) equals 225: (1, 225) (3, 75) (5, 45) (9, 25) (15, 15)
Punctuation mark is another word for parentheses or brackets.
100 - 10 + 3 = 93 You don't need any parentheses.
-2w+14+10w=348w=20w=2.5
It's 2+(-34)=-10 So put the parentheses around the -34.
3(4 plus 7) equals 33
(-2)^3 equals -2 times -2 times -2 which equals -8
60(x - 15) = 2500 (then simplify the left side of the equation) 60x - 900 = 2500 (then add 900 from both sides of the equation) 60x = 3400 (thn divide both sides by 60 to solve for x) x = 56.66666 (56-2/3)
The parentheses would be placed thus: 27 - (49 / 7 + 12) = 8
