- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
r = 4s
r = 1/2s + 7
<u>Step 2: Solve for </u><em><u>s</u></em>
<em>Substitution</em>
- Substitute in <em>r</em>: 4s = 1/2s + 7
- Subtract 1/2s on both sides: 7/2s = 7
- Divide 7/2 on both sides: s = 2
<u>Step 3: Solve for </u><em><u>r</u></em>
- Define equation: r = 4s
- Substitute in <em>s</em>: r = 4(2)
- Multiply: r = 8
Answer:
D is your answer
Step-by-step explanation:
y = x - 3
y = 2
x = 5
now insert the x and y into the equation
2 = 5 - 3
then subtract
2 = 2
last to find out if your right when both numbers equal each other like 2 = 2 then that will be you answer to your problem
Answer:
The waitress who received 20% of $20 gets a larger tip.
The waitress who received 20% of $20 gets $4.00 tip, and the waitress who received 15% of $25 gets a tip of $3.75
Step-by-step explanation:
To get 15% of 25, you multiply it by .15, giving you your answer.
To get 20% of 20, you multiple it by .20, giving you your answer.
Answer:
It is a relative minimum and an x-intercept.
Answer:
x = 27
Step-by-step explanation:
Since l, m, and n are cut across by the two transversal lines, therefore, the transversal lines are cut off proportionally.
This implies that:
6/x = 10/45
Cross multiply
x*10 = 45*6
10x = 270
10x/10 = 270/10
x = 27
