-5x+y=-2 solve system of equations by subtraction

1 answer:

8 0

Let's solve for x.
-5x+y= -2

step 1: add -y to both sides.
-5x + y -y = -2 + -y
-5x = -y -2

step 2: divide both sides by -5
-5x/-5 = -y-2/-5

answer:
x= 1/5 y+ 2/5

What is the area of a regular octagon with a apothem of 16 inches long and a side of 19 in Long round the answers to the nearest

azamat

To find the area of any regular (regular means all sides are = and all angles are =) poylgon when you know the length of the apothem and the length of the side you can use the formula:
A = (1/2)ap where a = the length of the apothem and p = the perimeter of the polygon. You can also use n*s in place of p where n = the number of sides of the polygon and s = the length of the side.

A= (1/2)(16)(19*8) (An octagon has 8 sides.)
A = 1216 in^2

xenn [34]

Answer:

angle ABC = angle MNP

(See the single curved shape at angle B? Match it to the same one on the other triangle. The same with the double and triple angles. The marks in the middle of the lines work the same way. Lines BC, BA, NM, and NP are all the same length.)

Answer:

3(4+√2)

Step-by-step explanation:

Here we need to find the perimeter of the given figure. Here the given figure is made from a triangle and a square. The side lenght of the square is 3. We need to find the hypontenuse of the triangle in order to find Perimeter .

• Using Pythagoras Theorem :-

⇒ h² = p² + b²

⇒ h² = 3² + 3²

⇒ h² = 9 + 9

⇒ h² = 18

⇒ h = √[ 9 × 2 ]

⇒ h = 3√2 .

Therefore the perimeter will be ,

⇒ P = 3√2 + 3 + 3 + 3 + 3

⇒ P = 3√2 + 12

⇒ P = 3( 4 + √2)

<h3>Hence the perimeter of the figure is 3(4+√2) .</h3>

X + 11 < 6 Solve and graph on a number line

Drupady [299]

Answer & Step-by-step explanation:

So I can't exactly graph exactly, but I'll try...

To solve:

x+11<6 Subtract 11 on both sides.

x<-5

To graph:

<-------|---------o---------|-------->

-6 -5 -4

(The bolded part of the line is the side you shade the graph on. In case you can't see it, you have to shade the left side of the open circle.)

Hope this helps! Have an awesome day ( • ω • )^

There are 1,200 students at Roosevelt middle school. There are 700 boys at the school. What percentage of the students at Roosev

Stella [2.4K]

Out of 1,200 students, 700 are boys. Therefore, the fraction would be $\frac{700}{1200}$ .

To convert this into a percentage, divide 700 by 1,200.

$\frac{700}{1200}$ = 0.583333 (or just 0.583 if you round)

Multiply 0.583 by 100 to get a percentage.

0.583 · 100 = 58.3

So, the percent of boys at the school is 58.3%.
