Solve for n. 11 = -3n+ 5

Mathematics

1 answer:

Alex787 [66]3 years ago

4 0

Answer:

n= -2

Step-by-step explanation:

11= -3n + 5

subtract 5 from both sides of the equation and you get:

6= -3n

now you have to isolate n, and to do that you use inverse operation.

Therefore, divide each side of the equation by -3

6/-3 = -3/-3

Lastly,

-2= n

Hope this helps!

in a triangle two sides of the same length the ratio of each of these sides to the third side is 5:3 if the perimeter of the tri

AveGali [126]

Answer:

Step-by-step explanation:

Perimeter of a triangle equals side 1 plus side 2 plus side 2

P = s1 + s2 + s3 side 1 = side 2 = x

x/side 3 = 5 / 3

x = (5/3) side 3

x (3/5) = side 3

perimeter = 65 slove for x

65 = x + x + 3x/5

325 = 5x + 5x + 3x

325 = 13X

25 = x equal side 1 and side 2

side 3 = 25(3/5) = 15

a cardboard box holds 31.25 cubic inches of creamy butter. The butter is molded into a square prism that is 5 inches long. How m

lesya [120]

Answer:

$62.5 \:in^2$

Step-by-step explanation:

Volume of the butter in the cardboard = 31.25 cubic inches

Length of the Molded Square Prism =5 Inches

Let the length of the square cross sectional area = x

Volume of the Prism $=x^2l$

Since l=5 Inches

$5x^2=31.25\\x^2=6.25\\x=2.5\: Inches$

Next, we determine the surface area of the New Cardboard box to be made.

Length of the Cardboard Box=5 Inches

Length of the square cross sectional area = 2.5 Inches

Total Surface Area $=2(x^2+xl+xl)=2(x^2+2xl)$

$=2(2.5^2+2(2.5)(5))\\=2(6.25+25)\\=2*31.25\\=62.5 \:in^2$

Therefore, $62.5 \:in^2$ of cardboard is needed,

X intercept<br> Of v^2 +5v+6=0

postnew [5]

Answer:

<h2>x-intercepts:</h2><h2>x = -2 and x = -3 ⇒ (-2, 0) and (-3, 0).</h2>

Step-by-step explanation:

$f(v)=v^2+5v+6\\\\\text{The x-intercept is for y = 0.}\\\\v^2+5v+6=0\\\\v^2+2v+3v+6=0\\\\v(v+2)+3(v+2)=0\\\\(v+2)(v+3)=0\iff v+2=0\ \vee\ v+3=0\\\\v+2=0\qquad\text{subtract 2 from both sides}\\v=-2\\\\v+3=0\qquad\text{subtract 3 from both sides}\\v=-3$

The triangle ABC was dilated with a scale factor of 5 to form a figure with new coordinates at A'(-15, -5), B'(10, -10) and C'(-5, -20).

<h3>What is transformation?</h3>

Transformation is the movement of a point from its initial location to a new location. Types of transformation are<em> reflection, translation, rotation and dilation.</em>
