<em>Greetings from Brasil... </em>
Check Attachment!!!
According to the statement of the question, we have:
a/b = 3/4
<em>Note that according to the attached figure, </em><em>b > a</em><em>, then the correct proportion will be </em><em>a</em><em> to </em><em>3</em><em>, as well as </em><em>b</em><em> to </em><em>4</em><em>, because </em><em>b > a</em><em> and </em><em>4 > 3</em>
Isolating a and b:
a = 3b/4
b = 4a/3
From Pythagoras:
h² = a² + b² - as a = 3b/4 and b = 4a/3, so
<h3>b = 4h/5</h3><h3>a = 6h/5</h3>
For Area:
A = b.a/2
as b = 4h/5 and a = 6h/5, so
<h3>A = 12h/25</h3>
Answer:201 students
Step-by-step explanation: Since there are seven kids riding in cars, you would subtract 7 from 1213 to get 1206 students. The six buses means you divide by 6 to get 201 students in each bus.
Answer:
You''ll have 3 boxes of eggs.
Step-by-step explanation:
1 x 3 = 3
It depends on how many eggs are in the box. If there were a dozen eggs then that would be thirty six.
I hope this helps!
Eliminate parenthesis by using the distribution property
= 5x² -3x +3 - x² - 2x +1
Group similar terms
= (5-1)*x² + (-3 -2)*x + (3+1)
Then sum everything:
= 4x² -5x +4
Answer:
Infinite amount of solutions.
General Formulas and Concepts:
- Order of Operations: BPEMDAS
- Regular + Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
6y + 4 - 3y - 7 = 3(y - 1)
<u>Step 2: Solve for </u><em><u>y</u></em>
- Combine like terms: 3y - 3 = 3(y - 1)
- Distribute 3: 3y - 3 = 3y - 3
- Subtract 3y on both sides: -3 = -3
Here we see that there will be infinite amount of solutions. We can plug in any number <em>y</em> and it will render the equation true.
