Answer-
1. 3(2) + 5=6+5 = 11
2. 4(3) - 7 =12-7= 5
3. 2(3) - 4 =6-4 = 2
4. 6(4) - 2(3) =24-6 = 18
5. 2+3-4+5 = 5-4+5= 1+5 = 6
6. 7(4) - 2(2) = 28-4= 24
7. 2(3)(4) + 1 = 24+1 = 25
8. 2(3)(4) - 4 = 24-4 = 20
9. 8(2) /4 = 16/4 = 4
10. 6(3)/2 =18/2 = 9
11. 4(2) + 7 = 8+7 = 15
12. 2(4) - 7 = 8-7 = 1
13. 2(3) + 3(2) = 6+6 = 12
14. 6(2) - 1 = 12-1 = 11
15. 3(4) - 2 = 12-2 = 10
Answer:
$3.00
Step-by-step explanation:
5x + 3y = 30 - - - - - 1 x 4
3x + 4y =29 - - - - - -2 x 3
--------------------------------------------
20x +12y = 120 - - - - 3
9x + 12y = 87 - - - - - 4
--------------------------------------------
3-4
20x - 9x= 120 - 87
11x = 33
X= 33
11
X = 3
Answer:
x + 8 + 12 + 11 = 43
Step-by-step explanation:
The perimeter is the length of the 4 sections of fencing.
If x represents the fourth section and the perimeter is 43, then
x + 8 + 12 + 11 = 43, that is
x + 31 = 43 ( subtract 31 from both sides )
x = 12
The length of the fourth section is 12 ft
