Answer:C. (4,5)
Step-by-step explanation:
The first equation can be simplified to y=1/2x +3.
9/4 cups of flour is equal to 2 1/4 2/4 cups of flour is equal to 1/2 SO 16/4 cup flour is equal to 4 Which is 7/4 cups more than 2 1/4 7/4 cups is 1 3/4 cups (1/2 a cups less than 2 1/4) Which means he needs 1 3/4 cups of walnuts.
<span>Simplfied- 4 cups is 1/2 a cups short of double, since the flour is done is quarters, take the 1/4 cup away from the walnuts. </span>
<span>(times 1/2 by 1/2 you get 1/4 subtract it)</span>
You can add and subtract radicals by ensuring that they have same radical parts.
<h3>What's radical?</h3>
It should be noted that a radical expression is an expression that contains the radical symbol which is ✓.
The necessary steps to add or subtract radicals include:
Identify the radical parts.
Add them together.
If there's unlike radical parts, one will manipulate the parts involved before solving.
Example: Add ✓63 + 5✓7
It should be noted that ✓63 = ✓9 × ✓7 = 3✓7
Therefore, ✓63 + 5✓7 will be:
= 3✓7 + 5✓7
= 8✓7.

The answer would be D) 9 + (-9) = 0 because additive inverse is a number added to its opposite to get zero so 9 is the additive inverse of -9 and -9 is the additive inverse of 9.
In this question, you are given the water volume(6.2 cubic ft) and the water density (8.33 pounds/gallon). To find the water mass you need to multiply the volume with density, but you need to convert it so they have same unit.
The calculation would be:
mass = volume x density
mass = 6.2 cubic ft x 7.48 gallon/cubic ft x 8.33 pound/gallon= 386.31208 pounds.
In ounce it will be= 386.31208 pounds x 16 ounce/pouns= 6180,99328 ounces
