Answer:
When ordering three or more fractions from least to greatest, compare two fractions at a time. It is helpful to write a number in a circle next to each fraction to compare them more easily.
40 divided by 45 equals about 0.89
so its 89%
{-2x + 7y = -5
{-2x - 4y = 6 | · (-1)
{-2x + 7y = -5
{2x + 4y = -6 (+)
----------------------------------
-2x + 2x + 7y + 4y = -5 + (-6)
11y = -11 | : 11
y = -1
{y = -1
{2x + 4y = -6
{y = -1
{2x + 4 · (-1) = -6
{y = -1
{2x - 4 = -6 | + 4
{y = -1
{2x = -2 | : 2
{y = -1
{x = -1
Answer:
56
Step-by-step explanation:
Since you said in order, 5+5+6+7 is 23 and times 2 equals 46 and add 10 to 56, (5+5+6+7)x2+10=56
21 is .368
22 is .71
23 is .66
24 is .1, 3/9, 2/3, 4/5, and 1.0
25 is .4, .42, .5, .55, .6
