Answer:

Millie is 11. Molly is 8.

Step-by-step explanation:

Step 1: Subtract 3 from 19. The reason why you do this is to make sure that you don't have an extra 3 lying in there for the next few steps.

19-3=16

Step 2: Divide 2 from 16. You do this because there are two sisters.

16÷2=8

8 will then become Molly's age

Step 3: Add 3 to 8. This will give you Millie's age because she is 3 years older than Molly.

3+8=11

In conclusion, Millie is 11 and Molly is 8.

Answer:

  (x, y, z) = (x, x+2, 3x+1)

Step-by-step explanation:

We can add twice the second equation to the first to get ...

  [eq4] -3x +0y +z = 1

Adding the first and second equations gives ...

  [eq5] -x +y +0z = 2

Solving [eq4] for z gives ...

  z = 3x +1

Solving [eq5] for y gives ...

  y = x +2

Then the solution triple is (x, y, z) = (x, x+2, 3x+1).

En total, Juan gastó $205.25. 1 kilo de queso cuesta $90. 1/2 kilo de jamón cuesta $60. Si comprara un kilo de tortilla, un kilo de pepino y un kilo de jamón, Juan gastaría $129. Si Juan tiene $430, puede comprar 3 kilos de jamón, 1 kilo de queso, 5 kilos de pepino y 1 2/3 de tortillas.

Dado que Juan compró 1/4 de pepino que cuesta $3, 1 1/2 de jamón que cuesta $120, 1/3 de tortillas que cuesta $6 y 4/8 de queso que cuesta $45, para determinar cuánto dinero gastó en total, cuánto cuesta un kilo de queso, cuánto cuesta medio kilo de jamón, cuánto gastaría si comprara un kilo de tortilla, un kilo de pepino, y un kilo de jamón y, si Juan tiene $430, qué puede comprar sin que le sobre ni un peso, se deben realizar los siguientes cálculos:

Answer:

m∠EFD = 90°

m∠EHF = 127°

m∠HFG = 56°

m∠G = 71°

m∠E = 19°

Step-by-step explanation:

From inspection of the given diagram, line segment GD is a straight line and m∠EFG=  90°.  

Angles on a straight line sum to 180°:

⇒ m∠EFG + m∠EFD = 180°

⇒ 90° + m∠EFD = 180°

⇒ 90° + m∠EFD - 90° = 180° - 90°

⇒ m∠EFD = 90°

Angles on a straight line sum to 180°:

⇒ m∠EHF + m∠FHG = 180°

⇒ m∠EHF + 53° = 180°

⇒ m∠EHF + 53° - 53° = 180° - 53°

⇒ m∠EHF = 127°

From inspection of the given diagram, m∠EFH and m∠HFG form a right angle:

⇒ m∠EFH + m∠HFG = 90°

⇒ 34° + m∠HFG = 90°

⇒ 34° + m∠HFG - 34° = 90° - 34°

⇒ m∠HFG = 56°

Interior angles of a triangle sum to 180°:

⇒ m∠HFG + m∠GHF + m∠G = 180°

⇒ 56° + 53° + m∠G = 180°

⇒ 109° + m∠G = 180°

⇒ 109° + m∠G - 109° = 180° - 109°

⇒ m∠G = 71°

Interior angles of a triangle sum to 180°:

⇒ m∠E + m∠EFH + m∠EHF = 180°

⇒ m∠E + 34° + 127° = 180°

⇒ m∠E + 161° = 180°

⇒ m∠E + 161° - 161° = 180° - 161°

⇒ m∠E = 19°

Therefore value of x is 25 .

Now, finding the the measure of each angle by putting the value of "x" in their places.

∠A = (x + 10)° => (25 + 10)° => 35°

∠B = (3x + 5)° => (3×25 + 10)° => (75 + 5)° => 80°

∠C = (2x + 15)° => (2 × 25 + 10)° => (50 + 15)° => 65°

Answer:

Step-by-step explanation:

3x + 4y = 24

Find the x intercept by solving intersecting the graph of f(x) or y with

y=0 (which is the x-axis)

4y= -3x+24, subtract 3x from both sides of the equation

y = (-3x/4) +6, divide both sides by 4

if y=0 then  

(-3x/4) +6 = 0  , subtract 6 from both sides

-3x/4 = -6, multiply both sides by 4

-3x = -24 , divide both sides by

x= 8, so the x intercept is at (8, 0)

the general formula of a line is y=mx+b , where b is the y-intercept

since our equation is y = (-3x/4) +6 then y intercept is at (0, 6)

Step-by-step explanation:

Length and width of rectangular rose garden is 15 and 5 feet

Given that;

Perimeter of rectangular rose garden = 40 feet

Length of the garden = 5 more  than twice the width

Find:

Dimensions of the rose garden

Computation:

Assume;

Width of garden = a

So,

Length of the garden = 2a + 5

Perimeter of rectangle = 2[l + b]

40 = 2[2a + 5 + a]

40 = 2[3a + 5]

40 = 6a + 10

6a = 40 - 10

6a = 30

a = 5

Width of garden = 5 feet

Length of the garden = 2a + 5

Length of the garden = 2(5) + 5

Length of the garden = 15 feet

Step-by-step explanation:

Answer:

y = -1/2x + 5

Step-by-step explanation:

x + 2y = 10

Step 1: subtract x from both sides.

you will get:    2y = -x + 10

Step 2: get the y by itself, you can do this by dividing 2 by both sides.

=  2y = -x + 10

     y = -1/2x +10/2

Then, 10/2 simplifies to 5.

So, your answer is: y = -1/2x + 5

Answer:

A  angles are 15 and 75    B.  angles are 30 and 60     C.  angles are 36 and 54

Step-by-step explanation:

Remember that the two acute angles of a right triangle = 90

A  one angle = x ; the other angle = 60 + x     so  60 +x + x = 90

 60 + 2x = 90; 2x = 30;  x = 15  one angles; the other angle is 60 + 15 = 75

B.   One angle = x ; the other angle = 2x     so  x + 2x = 90

     3x = 90 ; x = 30 one angle;    the other angle s 2x = 2(30) = 60  

C    2 : 3 means 2x:3x

       One angle = 2x ; the other angle = 3x ;  so  2x + 3x = 90

       5x = 90;  x = 18  this is what x is equal to.  Now the find the angles:

       one angle is 2x meaning 2(18) = 36 and the other angle is 3x meaning              3(18) = 54.    

To check this answer one angle to the other angle is represented by the ratio 2:3;   36:54 = 2:3   Reduced!

The distance, in feet, between the ground and the top of the ladder is 8 feet.

The diagram formed will be a right triangle having the hypotenuse, adjacent and opposite sides

To get the  distance, in feet, between the ground and the top of the ladder, we will use the Pythagoras theorem as shown:

Given the following sides

Substitute the given parameters into the formula to have:

10² = opp² + 6²

opp²=100 - 36

opp² = 64

opp = 8feet

Hence the distance, in feet, between the ground and the top of the ladder is 8 feet.
