Find x in each triangle.<br> PLZ HELP!!!

jonny [76]

Answer:

Step-by-step explanation:

Use the Pythagorean theorem:

$a^2+b^2=c^2$

a and b are the legs and c is the hypotenuse (x)*

Insert the values:

$3^2+1.6^2=x^2$

Simplify exponents

$9+2.56=x^2$

Simplify addition:

$11.56=x^2$

Find the square root:

$\sqrt{11.56}=\sqrt{x^2}$

$3.4=x\\x=3.4$

Finito.

*The hypotenuse is the side opposite the 90° angle and the longest side of a triangle, always.

Factor out the greatest common factor 6ab+9bc

Aleonysh [2.5K]

Ab+ac=a(b+c)
a is common factor
factor

6ab=2*3*a*b
9bc=3*3*b*c
common factor is 3*b or 3b

3b(2a)+3b(3c)=3b(2a+3c)

Answer:

<h2>3 3/4 Crates of Oranges</h2>

Step-by-step explanation:

We use a proportion to solve this. There are many steps involved, so I'll put each one separate, so you can easily follow.

<h3>Step 1: Set Up a Proportion</h3>

$\frac{0.5}{2.5} = \frac{0.75}{x}$

<h3>Step 2: Cross-Multiply</h3>

$\frac{1}{2}x = \frac{3}{4} * 2\frac{1}{2} \\\frac{1}{2}x = 1\frac{7}{8} \\$

<h3>Step 3: Isolate x</h3>

$1\frac{7}{8} * 2 = 3\frac{3}{4}$

$x = 3\frac{3}{4}$

<h3>Step 4: Check</h3>

$\frac{0.5}{2.5} = \frac{0.75}{3.75}$

$\frac{1}{2} * 3\frac{3}{4} = \frac{3}{4} * 2\frac{1}{2}$

$1\frac{7}{8} = 1\frac{7}{8}$ ✔

<h3>Step 5: Answer</h3>

3 3/4 crates of oranges

I'm always happy to help :)
