Multiply 64 x 23 first. That's 1472.
Now adjust the result.
6.4 is 1/10th of 64 and 2.3 is 1/10th of 23
so the answer is 1/10th of 1/10th = 1/100th of the result.
1/100th of 1472 = 14.72

53,11 x+y=64 x-y=42 combine terms 2x=106 x=53 substitute x and solve for y 53+y=64 y=11
4. 24 = 23 x 3 36 = 22 x 32 64 = 26 hcf = 22 = 4
24 = 23 x 3 64 = 26 88 = 23 x 11 factors in common: 23... 1, 2, 4 & 8
The first ten positive integer multiples of 64 are:1 x 64 = 642 x 64 = 1283 x 64 = 1924 x 64 = 2565 x 64 = 3206 x 64 = 3847 x 64 = 4488 x 64 = 5129 x 64 = 57610 x 64 = 640
64 + 23 = 87 64 x 23 = 1472
64 x 23 = 1472
x2-64 = (x-8)(x+8)
26 = 64
64 = 8 x 8 = 23 x 23 = 2 x2 x 2 x 2 x 2 x 2 = 26
64 = 8 x 8 = 23 x 23 = 2 x 2 x 2 x 2 x 2 x 2 = 26

x^2 = 64 x = +,- square root of 64 = +,- 8. Thus, x = -8 or x = 8
-8x + 6 = -58 -8x = -64 x= -64/-8 x = 8
8. 8(number of min.) x _ = 64 (number of min.) 8x_=64 and _=8
Devide both sides by 64 X=0.1875 0.1875 *64= 12
Just add 24 to both sides It cancels on the left, isolating x, then your left with 64 -24+x=40 X=64
