The volume of the triangluar block is 4 cubic inches. What is the approximate length of y? -- 2.8 inches
Answer:
You can use Gaussian Elimination.
Double both sides of the first equation and add the second equation.
6x + 4y = 8
5x - 4y = 3
---------------
11x = 11
x = 1
5 - 4y = 3
-4y = -2
y = 1/2
Step-by-step explanation:
Answer:
142 3/8
Step-by-step explanation:
45 + 42 = 87
87 + 54 = 141
7/8 + 3/8 = 1 2/8
1 + 141 = 142
2/8 + 1/8 = 3/8
Answer:
(24x+9)yd
153yd
Step-by-step explanation:
The perimeter is the sum of all the sides, so put all the sides together.
(7x+3)+(6x+3)+(6x+3)+(5x)
7x+6x+6x+5x+3+3+3
24x+9
IF x=6:
(24(6)+9)yd
(144+9)yd
153yd
