Answer:
88 miles.
Step-by-step explanation:
$.40 x 88(miles) = $35.2
$35.2 + $45 = $80.20
Now, the reason it is 88 is because 87 miles would equal
$.40 x 87 = $34.8 (total is $79.80) so that would be $.20 short.
Answer:
6/5 or 1.2
Step-by-step explanation:
you can solve with an equation:
x : 5 = 12 : 50
x = 5 * 12 : 50
x = 6/5 (or 1.2)
or you can solve with an expression
12/50 * 5 = 6/5 (or 1.2)

Answer: Option D, 16/21
Answer:
f(g(2)) = 22
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 3x + 1
g(x) = 2x² - 1
<u>Step 2: Find g(2)</u>
- Substitute: g(2) = 2(2)² - 1
- Evaluate: g(2) = 2(4) - 1
- Multiply: g(2) = 8 - 1
- Subtract: g(2) = 7
<u>Step 3: Find f(g(2))</u>
- Define: g(2) = 7
- Rewrite: f(7)
- Substitute: f(7) = 3(7) + 1
- Multiply: f(7) = 21 + 1
- Add: f(7) = 22
And we have our final answer!
Answer:
x = 3 && y = - 1
Step-by-step explanation:
Just solving the two equations
the first equation
y = 4/3 x +3
y - 4/3 x = 3 ..............................................(1)
the second equation
y = -2/3x -3
y + 2/3 x = -3 ..............................................(2)
by substracting 2 from 1
-4/3x - 2/3x = -6
divide by -1
4/3x +2/3x = 6
6/3x = 6
2x = 6
x= 3
then subsititute by value x in any of given eqautions
