Answer: Brian ran 9 miles
Sonia ran 24 miles
Step-by-step explanation:
Let's Brian's distance be represented by x.
Since Sonia ran 6 miles more than twice as far as Brian. This will be:
= (2 × x) + 6
= 2x + 6
Therefore,
x + 2x+6 = 33
3x + 6 = 33
3x = 33 - 6.
3x = 27
x = 27/3
x = 9
Brian ran 9 miles
Sonia ran = 2x+6 = 2(9).+ 6 = 18+6 = 24 miles
Answer:
Step 1: Define your variables. You should begin with a specific research question. ...
Step 2: Write your hypothesis. ...
Step 3: Design your experimental treatments. ...
Step 4: Assign your subjects to treatment groups. ...
Step 5: Measure your dependent variable.
Step-by-step explanation:
Generally, the experimental unit is the person, animal, or object that is the subject of the experiment. Experimental units receive different treatments from one another in an experiment.
<span>Let y represent the original price of the game.
</span><span>Ella purchased a game that was on sale for 12% off, so she purchased at 0.88y
</span><span>sales tax in her county is 6%
</span> final cost = 1.06(0.88y)
<span>answer
</span>1.06(0.88y)
I got 96.09%
--
1.7% x 10= .17
.17 x 23= 3.91
100%-3.91= 96.09%
Answer:
A = x⁵ + 13x³ - 9x² + 40x - 72
Step-by-step explanation:
The formula for the area of a rectangle is length X width, or A = lw.
Substitute the equations for the sides into the formula:
A = lw
A = (x² + 8)(x³ + 5x - 9) <= use the distributive property
A = x⁵ + 5x³ -9x² + 8x³ + 40x - 72 <= collect like terms
A = x⁵ + 13x³ - 9x² + 40x - 72
