Answer:

1a + 3

Step-by-step explanation:

What's the perimeter of a triangle?

  ❖ The perimeter of a triangle is the distance around a triangle, or the

       sum of all its side lengths.

How does it apply here?

  ❖ In this case, we're given the perimeter of the triangle as 3a + 11. We

      also have two dimensions of the triangle: 2a and 8. Now, we need to

      find the third side. To find the third side, we subtract 2a + 8 from 3a +

      11.

Solving

Now, let's check if 1a + 3, 2a, and 8 add up to 3a + 11.

Therefore, the answer is 1a + 3.

Step-by-step explanation:

Pages is directly proportional to Minutes

P = KM

k = P/M

when P = 6, M = 12.

k = 6/12

k = 0.5

_____________________

when M = 1

P = Km

P = 0.5×1 = 0.5

P = half a page.

______________________

when M = 6

P = 0.5× 6

P = 3 pages

______________________

when M = 17

P = 0.5×17 = 8.5

P = 8 and half pages

The scale that Denise used for a community college and made a scale drawing is 3 centimetres: 2 meters.

Given that;

Denise measured a community college and made a scale drawing.

Now, for the scale Denise used, set up a proportion using the measurements from the drawing and real life.

So, from the proportion:

3 centimetres (drawing): x meters (real life) = 183 centimetres (drawing): 122 meters (real life)

Using cross-multiplication, solve for x:

3 centimeters × 122 meters = 183 centimeters × x meters

366 centimeters meters = 183 centimeters x meters

Now divide both sides of the equation by 183 centimetres to isolate x:

366 centimetres meters / 183 centimetres = x meters

x = 2 meters

Therefore, the scale Denise used is 3 centimetres: 2 meters.

Answer:

135kg

Step-by-step explanation:

In room number one, there are five old models and a new model, which weights 240kg. So, it can be concluded that there are 6 models in there, and we can write it as 5x ( x = old models ) + 240 ( weight of new model ). then informed room number two, there are 3 old models and a new one, weighting 510kg. write it as 3x + 510.

the equation will be as: 5x + 240 = 3x + 510

move 3x to the front behind 5x, move +240 to the back behind 510. you will get 5x - 3x = 510 -240

which will be 2x = 270, then move 2 behind 270, means 270 divide 2, which then you will get 135kg

Hii.

First, lets divide 1/9 by 5 .

1/9 divided by 5 is 1/45

Lets multiply to find out the answer.

1/9 x 5 =5/9.

So this is not correct since it does not equal 1/45

9/1 x 5/1 is 45

This is not correct because it does not equal 1/45

1/9 x 1/5 is 1/45

This is correct because it equals 1/45

The fraction of the album that is still empty is 28/100, the correct option is A.

A fraction represents a part of a number or any number of equal parts.

A fraction consisting of a quotient and remainder is a mixed fraction. we can convert the mixed fraction to improper fraction by first dividing the numerator by denominator and then taking the quotient as whole number and remainder as the numerator of proper fraction keeping the denominator same.

We are given that;

The fraction 42/100

Now,

To rewrite 3/10 with a denominator of 100, we need to multiply both the numerator and denominator by 10. This gives us:

3/10 = (3 × 10) / (10 × 10) = 30/100

Now, we can add the numerators of the fractions and write the sum over the common denominator.

42/100 + 30/100 = (42 + 30) / 100 = 72/100

Therefore, the total fraction of the album that is filled with football and baseball cards is 72/100.

we need to subtract the fraction that is filled from the whole fraction, which is 1 or 100/100. To subtract fractions, we need to have a common denominator, which we already have as 100. So, we can subtract the numerators of the fractions and write the difference over the common denominator.

100/100 - 72/100 = (100 - 72) / 100 = 28/100

Therefore, the fraction will be 28/100.

Answer:

line 1: y= 1x+ 2

line 2: y= -1x-0.5

(usually 1 is omitted but I added for clarity)

Step-by-step explanation:

slope (x)= yfinal-yintial/xfinal-xinitial

b= where line intersects y axis

line 1:  (-1,0), (0.5,1.5)

(1.5-0)/(0.5-(-1))

(1.5)/(1.5)

slope= 1x

y=x+ 2

line 2: (-0.5,0), (0.5,-1)

(-1-0)/(0.5-(-0.5))

(-1)/(1)

slope= -1x

y=-x-0.5
