Answer:
x = 11.8639
Step-by-step explanation:
cos∅ = adjacent / hypotenuse
Since we are dealing with right triangles, we can use trig to help solve for missing values:
cos22° = 11/x
xcos22° = 11
x = 11/cos22°
x = 11.8639
Answer:
y = x + 2
Step-by-step explanation:
y - 3 = x - 1
+3 +3
y = x + 2
Answer:
$16000 invested in 4.25% and 16000 invested in 6.25%
Step-by-step explanation:
Let x be the amount invested in 4.25% and y be the amount invested in 6.25%
4.25%= 0.0425
6.25%= 0.0625
subtract x from both sides
total interest earned is 1680
Now solve for x and y
subtract 2000 from both sides
divide by -0.02 from both sides
x=16000

Step 1: Simplify each side, if needed.
Step 2: Use Add./Sub. Properties to move the variable term to one side and all other terms to the other side.
Step 3: Use Mult./Div. ...
Step 4: Check your answer.
I find this is the quickest and easiest way to approach linear equations.
Example 6: Solve for the variable.
