Answer 1

Answer:

1. x=-5

2. x=24

3. -1x+19

4. 14w²-4w

5. 5x-15

6. 11a²b-12ab²

7. 6x+4

8. x=15

9. x=-12

10. x=3

11. x=20

Step-by-step explanation:

15x-24-4x=-79 We have to add the like terms

+24 +24

15x-4x=-55 Subtract 15x-4x

11x=-55 Now divide

/11 /11

x=-5

3(2x-5)-4x=33 Use distributive property

6x-15-4x=33 Add like terms

+15 +15

6x-4x=48 Subtract 6x-4x

2x=48 Divide

/2 /2

x=24

6x+4+15-7x Combine 6x and -7x

-1x+4+15 Now combine 4 and 14

-1x+19

6w²+11w+8w²-15w Combine 11w and -15w

6w²+8w²-4w Now combine 8w² and 6w²

14w²-4w

12x-5-7x-11 Combine -5 and -11

12x-7x-15 Now subtract 12x-7x

5x-15

11a²b-12ab²

Nothing else can be done with this equation

2(3x+2)

6x+4

x/5=3

5×3=15

15=x

2/3x=-8

-4×2=-8

-4×3=-12

x=-12

10.

9x-11=-38

+11 +11

9x=-27

/9 /9

x=3

11.

-x/5+3=7

-3 -3

-x/5=4

-x=-20

x=20

Step-by-step explanation:

SA= 2 (Length x Breadth + breadth x height + Length x height)

SA= 2(2*5+5*6+6*2)=2(10+30+12)=104cm^2

2(3*4+4*5+5*3)= 2(12+20+15)=94cm^2

2(7*9+9*12+12*7)=2(63+108+84)= 510cm^2

SA=

[tex]A=2πrh+2π {r}^{2}

[tex]A=2πrh+2π {r}^{2} [/tex]

= 2π 6*5+2π6*6= 188.495+226.194

SA= 414.689 cm^2

2π7*4+2π*4*4=

SA=276.46 cm^2

2π6*4+2π*4*4=

SA= 251.33 cm^2

(3*4)/2=6

(3*8)=24

4*8=32

8*5=40

SA =6+6+24+32+40=108 cm^2

(6*8)/2=24

(6*8)/2=24

6*12=72

8*12=96

10*12=120

SA= 24+24+72+96+120= 336 cm^2

(5*12)/2=30

(5*12)/2=30

5*8=40

12*8=96

13*8=104

SA= 30+30+40+96+104= 300 cm^2

The variables x and y are proportional. Use the values to find the constant of proportionality. Then write an equation that relates x and y. Write any fractions in the simplest form. When y=20 , x=12.

Answers

Given:

y is proportional to x.

y=20 and x=12.

To find:

The constant of proportionality and the equation for the proportional relationship.

Solution:

y is proportional to x.

[tex]y\propto x[/tex]

[tex]y=kx[/tex] ...(i)

Where, k is the constant of proportionality.

Putting y=20 and x=12, we get

[tex]20=k(12)[/tex]

[tex]\dfrac{20}{12}=k[/tex]

[tex]\dfrac{5}{3}=k[/tex]

Putting [tex]k=\dfrac{5}{3}[/tex] in (i), we get

[tex]y=\dfrac{5}{3}x[/tex]

Therefore, the contestant of proportionality is [tex]k=\dfrac{5}{3}[/tex] and the equation for the proportional relationship is [tex]y=\dfrac{5}{3}x[/tex].

In a group of 20 students, 7 study both Art and Biology.
5 study Biology but not Art.
8 study neither subject.
Given that a randomly selected student studies Art, what is the probability the student studies Art and Biology?

Answers

Answer:

Step-by-step explanation:

A + B = 7

(Not A) + B = 5

(Not A) + (Not B) = 8

(Not A) = ((Not A) + B) + ((Not A) + (Not B) = 13

A = 20 - (Not A) = 7

Prob (A + B) given (A)

Prob (A+B) || A = (7/20) / (7/20)

Prob (A + B) || A = 1

4 boys have a mean height of 162cm.Another boy with a height of 165cm joins them.What is the new mean height?

Answers

Answer: 162.6cm

Step-by-step explanation:

4 boys have a mean height of 162cm. Their total height will be the average multiplied by the number of boys which will be:

= 162 × 4

= 648cm

A new boy with height of 165cm joined. This means that we now have 5 boys and their total height will be:

= 648cm + 165cm

= 813cm

The new mean height will be:

= Total height / Number of boys

= 813 / 5

= 162.6cm
