The equation gives the equivalence of the distance travelled by Lucy
and the number of laps.
Correct response:
- <u>A possible equation for the distance Lucy runs is; 4 × 35 miles = 140 miles</u>
<u />
<h3>Methods by which the equation is obtained</h3>
Given:
The distance of one lap round the lake = 35 miles
Number of laps Lucy runs = 4 laps
Therefore;
Distance Lucy runs = 4 × 35 miles = 140 miles
A possible equation for the distance Lucy runs is therefore;
- Equation for the distance Lucy runs = n × 35 = 34·n
Where;
n = Number of laps
When n = 4, we have;
- Distance Lucy runs = 4 × 35 miles = <u>140 miles</u>

Answer:
can you send the image ???
Step-by-step explanation:
Answer:
by adding the first equation and the second equation:
3x+4y=16
-3x+2y=-10
6y=6
y=1. then
by substuting the value of y in equation of 3x+4y=16
then
3x=16-4
3x=12
x=4
The answer is a
√120x = √4 × √30x
= 2√30x
Answer:
x = 1/3
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
4x + 1 = 3 - 2x
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 2x on both sides: 6x + 1 = 3
- Subtract 1 on both sides: 6x = 2
- Divide 6 on both sides: x = 1/3
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: 4(1/3) + 1 = 3 - 2(1/3)
- Multiply: 4/3 + 1 = 3 - 2/3
- Add/Subtract: 7/3 = 7/3
Here we see that 7/3 does indeed equal 7/3.
∴ x = 1/3 is a solution of the equation.
