<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
-x + 4y = -8
-5x - 4y = -16
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Elimination</em>
- Combine equations: -6x = -24
- Isolate <em>x</em>: x = 4
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: -x + 4y = -8
- Substitute in <em>x</em>: -4 + 4y = -8
- Isolate <em>y</em> term: 4y = -4
- Isolate <em>y</em>: y = -1
Answer: 5(k)
Step-by-step explanation: “k”times “t” equals 6t-9 so if “k” times “t” equals 21, 6t-9=21, add 9 to 21 which equals 30 so then you divide 30 by 6 to get 5. “t”=5 which means the solution is 5(k)
(I’m just a sixth grader dont blame me if I couldn’t do this)
Answer:
i don't what you want me to do here...
You gave me the same problem just two different numbers so maybe the answer is 7... idek tho bro
k times x = 7
k times x = 49
Step-by-step explanation:
The ratio is 0.394 cm. / 1 in.
$2.38/0.40 lb = $5.95/1 lb
The spinach cost $5.95 per pound.
Hope this helps you:)
