7/10 must be added to 3/10 to make a whole number, 1.
-3/4 - 3/7 = (-3×7)/(4×7) - (3×4)/(7×4) = -21/28 - 12/28 = -33/28 You need to add -33/28 = -1 5/28
The number 2.
What must be added to 3 tenths to make 1 whole
7/10 must be added to 3/10 to make 1 whole.
7 just 7
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
-7
Add 7 to 5,621, to get 5,628. That's (469 x 12).
Let the number be n.Then 3n + 7 = 1 : 3n = 1 - 7 = -6 : n = -6/3 = -2.Answer n = -2
The perimeter is all the sides added together so it would Be 3+3+7+7 the perimeter is 20
in the equation 3+4=7, 3 and 4 are the addends. 7 is the sum.
