x < 35 + 35 + 15x < 85x > 40 x 2x > 80Therefore x is between 81 to 84 (inclusive).The only number in this range in which the digits sum to 9 is 81.
the sum for 20 + 40 + 70 + 80 = 210
20+35+40+55+60+55+80=345
The sum of these numbers is 563.
7/8 + 9/10 Easy in decimal, .875 + .9 = 1.775 35/40 + 36/40 = 71/40 = 1 and 31/40
36 + 35 + 40 + 40 + 40 + 40 + 40 = 271 271 is the answer
x < 35 + 35 + 15x < 85x > 40 x 2x > 80Therefore x is between 81 to 84 (inclusive).The only number in this range in which the digits sum to 9 is 81.
the sum for 20 + 40 + 70 + 80 = 210
figure it out.
20+35+40+55+60+55+80=345
The sum of these numbers is 563.
50
The sum is 40
7/8 + 9/10 Easy in decimal, .875 + .9 = 1.775 35/40 + 36/40 = 71/40 = 1 and 31/40
40
75 = 40 + 35
7 40 plus 2 as the sum of two products can be expressed as 1.47 x 1.47.
