Answer:
x = 2, y = 1.
Step-by-step explanation:
3x + y = 7
2x - 3y = 1
Multiply the first equation by 3:
9x + 3y = 21 Add this to the second equation we get:
11x + 0 = 22
x = 2.
Substitute this value in the second equation:
2(2) - 3y = 1
-3y = -3
y = 1.
Answer:
1. 24 cubic units
2. 180 cubic units
3. 1/16 cubic units
Step-by-step explanation:
<u>Question 1</u>
Volume of a rectangular prism = width × length × height
= 3 × 4 × 2
= 12 × 2
= 24 cubic units
<u />
<u>Question 2</u>
Volume of a rectangular prism = width × length × height
= 5 × 12 × 3
= 60 × 3
= 180 cubic units
<u>Question 3</u>
Volume of a rectangular prism = width × length × height
= 1/4 × 1/2 × 1/2
= 1/8 × 1/2
= 1/16 cubic units
Step-by-step explanation:
Given
8(x - 1) = - 4x + 136
8x - 8 = -4x + 136
8x + 4x = 136 + 8
12x = 144
x = 144 / 12
x = 12
