Answer:
BC
Step-by-step explanation:
because they never intersect each other
2/25
To find percent divide 2 by 25
2 ÷ 25 = 0.08
Multiply 0.08 by 100 because percent is always out of 100
0.08 x 100 = 8 .
The answer is 8%
174/29 = 6 times the difference
17*6 = 102
12*6= 72
34*6 =204
15*6 = 90
so the answer is A

- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
4x + y = 2
y = x - 3
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: 4x + (x - 3) = 2
- Combine like terms: 5x - 3 = 2
- Isolate <em>x</em> term: 5x = 5
- Isolate <em>x</em>: x = 1
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: y = x - 3
- Substitute in <em>x</em>: y = 1 - 3
- Subtract: y = -2
