<u>Algebra I</u>
- Terms/Coefficients
- Coordinates (x, y)
- Solving systems of equations by substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
y = 5x
20x - 4y = 0
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em> [2nd Equation]: 20x - 4(5x) = 0
- Multiply: 20x - 20x = 0
- Combine like terms: 0 = 0
Here we see 0 does indeed equal 0.
∴ our systems has an infinite amount of solutions.
Gross pay is before taxes and everything is taken out. There a re 52 weeks in a year.
weekly pay = $52,000 / 52wks
= $1,000
Biweekly = 2 * $1,000
= $2,000
Monthly = $52,000 / 12 months
= $4,333.33
Answer:
Machine A makes 432 on Monday. Machine 2 makes 520 parts on monday. 432+520=952
Step-by-step explanation:
Answer:
x=16;y=8
Step-by-step explanation:
x=length
y=width
the length of a rectangle is twice the width
so,
x=2y........(1)
the perimeter is 48 inches
so,
2(x+y)=48
x+y=24....(2)
2y+y=24 [from 1]
y=8........(2)
so
x=2.8 [from 1 &2]
x=16
