Explanation:

s = Sam's age right now

2s = the mother's age right now, since she is twice as old as Sam currently.

In 12 years time, Sam will be s+12 years old.

12 years ago from this current year, the mother was 2s-12 years old.

Since we're told these future and past ages line up, this means s+12 and 2s-12 are the same value

Set the expressions equal to one another and solve for s.

s+12 = 2s-12

s-2s = -12-12

-s = -24

s = 24

Sam is currently 24 years old.

His mother is currently 2s = 2*24 = 48 years old.

12 years ago, his mother was 2s-12 = 48-12 = 36 years old.

12 years from now, Sam will be s+12 = 24+12 = 36 years old.

Since we get 36 each time, this confirms we have the correct answers.

Answer:

probs too late, but i think the answer is x=12

Step-by-step explanation:

the angles should add up to equal 180

180-36=144

144=8x+4x

144=12x

now divide by both sides to isolate x

12=x

u can check by plugging in ofc, 36+(8x12)+(4x12)=36+96+48=180

Answer:

A = -28

B = -22

C = -13

D = -4

E = 2

Step-by-step explanation:

Answer:

A = -21

B = -19

C = -13

D = -7

E = -4

Step-by-step explanation:

Looking at the only two numbers provided, and that one space between them, we can only assume that they're being increased by 3. :

-16 + 3 = C

-16 + 3 = -13

-13 + 3 = -10

So we can do the same for all answers except A and B because they're before -16. Instead for A and B, we subtract 3 because they're before -16.

-16 - 3 = B = -19

-19 - 3 = A = -21

-10 + 3 = D = -7

-7 + 3 = E = -4

-21 , -19 , -16 , -13 , -10 , -7 , -4

A      B               C             D   E

Answer:

Mrs. grub bought total number of shirts = 1

Mrs. grub bought total number of hats = 8

Step-by-step explanation:

Let Mrs. grub bought total number of shirts = x

Let Mrs. grub bought total number of hats = y

As given,

Price of 1 shirt = $4

Price of 1 hat = $12

⇒ Price of x shirts = $ 4x

   Price of y hats = $ 12y

Given that,

Mrs. Grubb bought total piece of clothes = 9

⇒ x + y = 9     .......(1)

Also given,

She bought all clothing for $100

⇒ 4x + 12 y = 100       ........(2)

Divide equation (2) by 4 we get

x + 3y = 25     .......(3)

Now,

Subtract equation (1) from equation (3) , we get

x + 3y  - ( x + y ) = 25 - 9

⇒ x + 3y - x - y = 16

⇒2y = 16

⇒y = [tex]\frac{16}{2}[/tex] = 8

⇒ y = 8

Put value of y in equation (3), we get

x + 3(8) = 25

⇒x + 24 = 25

⇒x = 25 - 24 = 1

⇒x = 1

∴ we get

Mrs. grub bought total number of shirts = x = 1

Mrs. grub bought total number of hats = y = 8

Answer:

I believe the answer is - they are the same shape but different sizes

Answer:

15cm by 20cm by 25cm

Step-by-step explanation:

Let the sides of the right angle be x, y and h

x is the breadth

y is the height

h is the hypotenuse

Perimeter = x + y + h

x + y +h  = 60

x+y = 60-h .... 1

If its area is equal to 150 square cm, then;

Area = 1/2 * base * height

Area = 1/2 *x * y

xy/2 = 150

xy = 300 ....2

According to pythagoras theorem;

x² + y² = h²

On expanding x² + y²

x² + y² = (x+y)² - 2xy

The equation becomes

(x+y)² - 2xy = h² ... 3

Substitute equation 1 and 2 into 3;

From 3;

(x+y)² - 2xy = h² ... 3

(60-h)² - 2(300) = h²

3600-120h + h² - 600 = h²

3600-120h - 600 = 0

-120h = 600-3600

-120h = -3000

h = 3000/120

h = 25cm

Recall that x+y+h = 60

x+y+25 = 60

x+y = 60 - 25

x+y = 35 ... 4

From equation 2;

xy = 300

x = 300/y ..... 5

Substitute 5 into 4;

300/y + y = 35

(300+y²)/y = 35

300+y² = 35y

y²-35y + 300 = 0

y²-20y-15y + 300 = 0

y(y-20)-15(y-20) = 0

y-20 = 0 and y - 15 =0

y = 20 and 15

since x+y = 35

x + 20 = 35

x = 35 - 20

x = 15

Hence the sides of the triangle are 15cm by 20cm by 25cm

Answer:

88,959

Step-by-step explanation:

it's subtraction. I got the answer

Answer:

88,959

Step-by-step explanation:

Clearly, we do the ones place first, and so..

054

-

095 =

We borrow from 5 which turns into 4 and 4 turns into 14.

14 - 5 = 9

So our first number is 9!

= __9

We borrow from the thousands, 3 becomes 2 and 0 becomes 10!

We can't subtract 4 from 9 so we borrow from 10, 10 becomes 9 and 4 becomes 14.

14 - 9 = 5

( Now i'm getting lazy so I will just show the steps without as many words )

9 - 0 = 9

~~~~~~~~~~~~~~~

054 - 095 = 959

! Hundreds place !

( 3 is now a 2 since we borrowed from 3)

272

-

184 =

( Borrowed from 7 to make 12 so 7 is now 6 )

12 - 4 = 8

~~~~~~~~~~~~~~~

(We need to borrow from the first 2 in 272 to make 16 from when we borrowed from 7 )

16 - 8 = 8

~~~~~~~~~~~~~~~

(2 was borrowed so it's now 1 )

1 - 1 = 0

~~~~~~~~~~

And we get 088,959

Remove the 0 and we have 88,959

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I hope this helps you!

Answer:

A: SSS | B: HL | C: SAS

Step-by-step explanation:

Firstly, SSS is where you know that each side of a triangle is congruent to the other triangle.

Secondly, SAS is where you know two sides and an angle are congruent. This angle will be between two sides that are congruent. This can be put clockwise or counterclockwise, but the sides and angle must be consecutive.

Thirdly, AAS is where you know two angles and one side are congruent.

Lastly, HL (Theorem) is where you know that the hypotenuse and a leg of a right triangle are congruent.

A: TU≅WX, ST≅XV, and SU≅VW

B: Two right triangles; HA and OK are the hypotenuses, and HA≅OK, RH≅RK

C: ZW≅YX, ∠W≅∠X, and WX≅WX

Answer:

6

Step-by-step explanation:

3√2x√2=6

Step-by-step explanation:

linear equations have one solution are:-

5x - 1 = 3(x + 11)

4(x – 6) + 4 = 2(x - 3)

2(x – 4) = 5(x – 3) + 3

Answer:

The linear equations that have one solution are:

5x - 1 = 3(x + 11)

4(x – 6) + 4 = 2(x - 3)

2(x – 4) = 5(x – 3) + 3

Answer:

8.48%

Step-by-step explanation:

Bill's weight decreases from 64.8 kg to 59.3 kg.

We need to find the percentage decrease in Bill's weight. It can be calculated as follows :

[tex]\%=\dfrac{64.8 -59.3 }{64.8 }\times 100\\\\=8.48\%[/tex]

So, the required decrease in percentage is 8.48%.
