So, standard form basically takes the shape of Ax+By=C. You want all of your variables to be on the left side and your constant on the right. There can also be no fractions!

In your case, since you didn't mention a y value for y, your line is y=-3/2x+6

first we get rid of the fraction by multiplying both sides of the equation by 2:
(2)y= (-3/2x+6)(2) and get
2y=-3x+12
now all there is left to do is get x to the other side by adding it to both sides:
3x+2y=12 is your final answer

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²

a is a leg
b is another leg
c is the hypotenuse

Step-by-step explanation:

Step 1: Identify

a = x + 3

b = x

c = √117

Step 2: Solve for x

Substitute [PT]: (x + 3)² + x² = (√117)²
Expand [FOIL]: x² + 6x + 9 + x² = (√117)²
Combine like terms: 2x² + 6x + 9 = (√117)²
Exponents: 2x² + 6x + 9 = 117
[SPE] Subtract 117 on both sides: 2x² + 6x - 108 = 0
Factor out GCF: 2(x² + 3x - 54) = 0
[DPE] Divide 2 on both sides: x² + 3x - 54 = 0
Factor Quadratic: (x - 6)(x + 9) = 0
Solve roots/solve x: x = -9, 6

Since we are dealing with positive values, we can disregard the negative root.

∴ x = 6

Igoryamba

Pete needs 10.5 ounces of turkey.

Step-by-step explanation:

Given,

Number of friends = 2

One for Pete.

Total sandwiches to be made = 2+1 = 3

Quantity of turkey in one sandwiches = 3.5 ounces

For finding the quantity of turkey for three sandwiches, we will multiply.

Turkey for 3 sandwiches = 3*3.5 = 10.5 ounces

Pete needs 10.5 ounces of turkey.
