Cross-Multiply
(5x/2)*(5)=(3/1)*(11)
12.5x=33
Divide both sides by 12.5
12.5x/12.5=33/12.5
x=2.64
I hope that's help ! Please don't forget to write it as a fraction in lowest terms. I am totally don't remember . Good night .
Answer:
Answer is at the bottom!!
Step-by-step explanation:
y = - \frac{2}{5} x - 2
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
rearrange 2x + 5y = 10 into this form
subtract 2x from both sides
5y = - 2x + 10 ( divide all terms by 5 )
y = - \frac{2}{5} x + 2 ← point- slope form with slope m = - \frac{2}{5}
Parallel lines have equal slopes hence
y = - \frac{2}{5} x + c is the partial equation of the parallel line
to find c, substitute ( 5, - 4 ) into the partial equation
- 4 = - 2 + c ⇒ c = - 4 + 2 = - 2
y = - \frac{2}{5} x - 2 ← equation of parallel line
Hope this helps!!
Answer:
Volume of rectangular prism = 1200 cubic inches
Step-by-step explanation:
Given that:
Length of rectangular prism = 10 inches
Width of rectangular prism = 8 inches
Height of rectangular prism = 15 inches
Volume of rectangular prism = Length * Width * Height
Volume = 10 * 8 * 15
Volume = 1200 cubic inches
Hence,
Volume of rectangular prism = 1200 cubic inches
Let Cameron be x years old now.
-
<u>Now:</u>
Cameron = x
Uncle =3x
-
<u>4 years ago:</u>
Cameron = x - 4
Uncle = 3x - 4
-
<u>4 years ago, Uncle is 4 times older:</u>
3x - 4 = 4(x - 4)
-
<u>Find x:</u>
3x - 4 = 4(x - 4)
3x - 4 = 4x - 16
4x - 3x = 16 - 4
x = 12
-
<u>Find the age:</u>
Cameron = x = 12
-
Answer: Cameron is 12 years old now.
4. 75x^3-48x
3x (25x^2-16)
3x (5x-4)(5x+4)
