Answer:

Janie is 12

Chad is 15

Step-by-step explanation:

27 - 3 = 24

24 : 2 = 12

12 + 3 = 15 (Chad)

27 - 15 = 12 (Janie)

Janie is three years younger than her brother Chad and she is 12 years old

Janie is 3 years younger than her brother Chad.

let

Chad age = x

Janie age = x - 3

The sum of there ages is 27. Therefore,

x + x - 3 = 27

2x - 3 = 27

2x = 30

divide both sides by 2

x = 30 / 2

x = 15

Chad age = 15 years

Janie's age = 15 - 3 = 12 years

Answer:

264.6

Step-by-step explanation:

Answer:

264.6

Step-by-step explanation:

ok first of all if you are subtracting a negative the it becomes a positive

136 - (-128.6)

136 + 128.6

this is what goes on in my head you don't have to do it this way but i do

100 + 100 = 200

30 + 20 = 50

6 + 8.6 = 14.6

200 + 50 + 14.6 = 264.6

Answer:

y = 50

Step-by-step explanation:

Firstly, let's make an equation. We know that when y is 15, x is 3. Or, in other words, y is 5 times what x is. Therefore we can use the equation, y = 5x.

Now, just plug x into the equation.

y = 5(10)

y = 50

Answer:

A = 2044 sqcm; P = 221 cm (PLEASE DOUBLE CHECK CALCULATIONS!!)

Step-by-step explanation:

the area of a triangle is half of its base times height.

the base and the height must be perpendicular to each other; so they would be 56 and 73.

56(73)/2=2044

the perimeter is the sum of all the sides

73+56+92=221

The area of the right-angled triangle is 2044 cm² and the perimeter of the right-angled triangle is 221 cm.

To find the area and perimeter of a right-angled triangle with dimensions 73 cm, 92 cm, and 56 cm.

Area of a right-angled triangle:

The area of a triangle can be found using the formula:

A = (1/2) x base x height

Plugging these values into the formula, we get:

A = (1/2) x 73 cm x 56 cm

A = 2044 cm²

Therefore, the area of the right-angled triangle is 2044 cm².

Perimeter of a right-angled triangle:

The perimeter of a triangle is the sum of all its sides.

In this case, the sides of the triangle are 73 cm, 92 cm, and 56 cm.

Perimeter = 73 cm + 92 cm + 56 cm

Perimeter = 221 cm

Therefore, the perimeter of the right-angled triangle is 221 cm.

Answer:

20

Step-by-step explanation:

Using order of operations, we have to divide 32 by 8 first since its in parentheses, then add and subtract from left to right, so: (32/8)+27-11 = 4 + 27 - 11 = 31 - 11 = 20

Answer:

X=-5

X=-7

Step-by-step explanation:

-12x+(-4)=56

rewrite the equation to -12x-4=56

add 4 to both sides

-12x=60

Divide by -12 on both sides

x=-5

-2.1x+(-3.9)=10.8

-2.1x-3.9=10.8

-2.1x=14.7

divide by -2.1 on both sides

x=-7

Answer:

y = 1/4x + 1.5

Step-by-step explanation:

To solve a problem like this we can use the formula y - y1 = m(x - x1), in which y1 is the y coordinate, x1 is the x coordinate, and m is the slope.

Equation:

y - 1 = 1/4(x + 2)

y - 1 = 1/4x + 0.5

y = 1/4x + 1.5
