6x-8+2x-5 = 7-2x 6x+2x+2x = 7+8+5 10x = 20 x = 20/10 x = 2
x*-4=8+(2-5*x) =-4x=8+2-x5 x*-4=8+(2-5*x) =-4x=8+2-x5 x*-4=8+(2-5*x) =-4x=8+2-x5
1 x 40, 2 x 20, 4 x 10, 5 x 8, 8 x 5, 10 x 4, 20 x 2, 40 x 1
The answer is 8. One fifth of 20 is 4 because 20/5 is 4, and 4*2=8
1/2*base*height = area 1/2*8*5 = 20 square units

2/5 of 20 is 8.(2 / 5) * 20 = 8
6x-8+2x-5 = 7-2x 6x+2x+2x = 7+8+5 10x = 20 x = 20/10 x = 2
The correct equation to solve 20 ÷ 4 x 4 + 8 equals 18 is as follows: First, divide 20 by 4 to get 5. Then, multiply 5 by 4 to get 20. Finally, add 8 to 20 to get the final answer of 28.
Do you mean a question like 20/5/2? Without any parentheses, the rule would be to work from left to right, dividing 20 by 5 first: (20/5)/2 = 4/2 = 2. If there were parentheses telling us to do the second division first, the answer would be different: 20/(5/2) = 20/2.5 = 8.
5/8 × 20 = 5/8 × 20/1 = (5×20)/(8×1) = 100/8 = 25/2 = 12½

the answer is 20. the formula is 1/2 * 8 * 5 then this will be 8 * 5 /2 = 40/2 20.
8/20 = 2/5
The fraction 8/10 is equal to 4/5. To solve, divide the numerator and denominator of 8/10 by 2. 8/2=4, 10/2=5 as such (8/10)/2=4/5 It is also equal to 16/20, 32/40, 64/80, 80/100 and so forth.

Always do the Multiplication/Division before Addition/subtraction. Hence 20 - 8 divide 2 x 5 = 20 - 4 x 5 = 20 - 20 = 0
