8 - (42/7) + (7 x 3) = 23
== == 7/12 - 11/12 = -4/12 or -1/3.
It is: (15-7)*(12-9) = 24
Subtract two, multiply by two, subtract one. :)
If you mean 8 and 7/12 subtract 2 and 3/8 then it is 6 and 5/24
18 ÷ 3 x 2 - 7 = 5
7/12 - 1/4 = 7/12 - 3/12 = 4/12 = 1/3.
8 - (42/7) + (7 x 3) = 23
You get 50.
== == 7/12 - 11/12 = -4/12 or -1/3.
It is: (15-7)*(12-9) = 24
4. Reverse the process to find the number: 7 is added to the product of 3 and a number to get 19. The last thing done is add 7; the reverse process of add is subtract, so subtract 7, leaving: The product of 3 and a number is 19 - 7 = 12. The reverse process to multiply (product) by 3 is divide, so divide by 3, leaving: a number is 12 ÷ 3 = 4
Subtract two, multiply by two, subtract one. :)
Start with the equation equaling 7; 3/4(X + 5) - 2 = 7 X + 5 = 4/3(7 + 2) = 4/3 x 9 = 12 X = 12 - 5 = 7
to triple a number that was decreased by five you subtract 5 and then multiply by three. for example if you where given 10 you would 12-5=7 -> 7*3=21
You are mistaken here with the words you use. You don't say "subtracted by". So I will show you seven twelfths subtract one fourth. 7/12 - 1/4 multiply 1/4 by 3 7/12 - 3/12 = 4/12 or = 1/3 divide by 3
3 x 7 = 21 29 -21 = -8
