Zero pairs are basically 2 numbers that add up to zero like -1 +1 = 0 they cancel each other out. By assigning tiles to represent each number, you can cancel out the zero pairs and the remaining tiles will represent the sum or difference of the numbers.
Answer:
x = 2
y = 1
Step-by-step explanation:
-2x-3y=-7, y=6x-11
-2x - 3(6x - 11) = -7
-2x - 18x + 33 = -7
-2x - 18x = -40
-20x = -40
<u><em>x = 2</em></u>
y = 6(2) - 11
y = 12 - 11
<u><em>y = 1</em></u>
Answer:
$62.1
Step-by-step explanation:
The tube of toothpaste shown cost $3.45. Estimate the price per cubic inch of toothpaste.
= Volume = Length × Width × Height
= 8 in × 1.5 in × 1.5 in
= 18 in³
From the above question:
1 in³ = $3.45
18 in³ = $x
Cross Mulitiply
x × 1 in³ = 18 in³ × $3.45
x = 18 in³ × $3.45/ 1 in³
x = $62.1
Therefore, the price per cubic inch of toothpaste is $62.1
