You can make a number line and draw the 0 to 5.
7/4=1 3/4
So, mark 1 3/4 between 1 and 2.
s<7/4
draw a small Hollow circle, draw a line to the 7/4 left.
That's all
Answer:y=4
Step-by-step explanation:
Combine like terms that share a common variable. If a scalar multiple is outside the parentheses, use the distributive property to expand the expression.
15) I cannot read the whole expression.
16) 4n - n = 3n
17) -3x - 9 + 15x = 12x - 9
18) -9k + 8k = -k
19) -16n - 14n = -30n
20) 15n - 19n = -4n
21) - 4 + 7(1 - 3m) = -4 + 7 - 21m = -21m + 3
22) -5n + 3(6 + 7n) = -5n + 18 + 21n = 16n + 18
23) -2n - (9 - 10n) = -2n - 9 +10n = 8n - 9
24) 10 - 5(9n - 9) = 10 - 45n + 45 = -45n + 55
25) 9a + 10(6a - 1) = 9a + 60a - 10 = 69a - 10
26) -9(6m - 3) + 6(1 + 4m) = -54m + 27 + 6 + 24m = -30m + 33
27) -10(1 - 9x) + 6(x - 10) = -10 + 90x + 6x - 60 = 96x - 70
28) 5(-2n + 4) + 2(n + 3) = -10n + 20 + 2n + 6 = -8n + 26
Answer:
180000
Step-by-step explanation:
2 significant figures means you see the digit next 2 second number. here next number is 5, then you round off second number to the next one. in the case 17 rounded to 18. rest all become 0000
hope it helps!
