17-14

= 3

I hope that's help !

Simply substitute the 7 in for c in the equation then solve...

17 - 2c =
17 - 2 (7) =
17 - 14 = 3

Answer:

He can fit 11 ft^3

Step-by-step explanation:

Here, we want to get the volume it clothes that could fit into the two boxes

What we have to do here is to add the amount of space each of the box has to offer

Mathematically, we have this as;

7 ft^3 + 4 ft^3 = 11 ft^3

Carla e Ana foram tomar sorvete e gastaram r$ 23,00 dividido a conta em partes iguais, quanto cada uma pagou ? Gente me explica

wariber [46]

Answer:

each of them has to pay $11.5 individually

Step-by-step explanation:

The computation of the amount paid by each one is shown below:

As carla and Ana gone for an icecream and the bill is $23 that should be divided equally

So here the carla should pay

= $23 ÷ 2

= 11.5

And, Ana should pay

= $23 ÷ 2

= $11.5

Hence, each of them has to pay $11.5 individually

Triangle ABC is graphed on a coordinate grid with vertices at A (-2, -4), B (2, -4) and C (0, 2). Triangle ABC is dilated by a s

Papessa [141]

Answer:

The rule which best represents the dilation that was applied to Triangle ABC to create A’B’C’ will be:

(x, y) → (1/2x, 1/2y)

Step-by-step explanation:

Given the vertices of a triangle

A(-2, -4)

B(2, -4)

C(0, 2)

After the dilation, the vertices of an image triangle be

A' (-1, -2)

B '(1, -2)

C' (0, 1)

If we closely observe, we can notice that the image triangle vertices A'B'C' are half of the original triangle ABC.

i.e. (x, y) → (1/2x, 1/2y)

verification

A(-2, -4) → A'(-2/2, -4/2) = A'(-1, -2)

B(2, -4) → B'(2/2, -4/2) = B'(1, -2)

C(0, 2) → C'(0/2, 2/2) = C'(0, 1)

Thus, it is verified and we conclude that the rule which best represents the dilation that was applied to Triangle ABC to create A’B’C’ will be:

(x, y) → (1/2x, 1/2y)

PLEASE HELP THANKS!!

mafiozo [28]

Answer: a) x = 5 b) x = 12

Step-by-step explanation: For each one you just do the inverse to get it on the other side of the equal sign. For example x + 3 = 8 would be like this :

1. x + 3 = 8

2. x + 3 - 3 = 8 -3

( + 3 - 3 cancels out)

3. x = 5

What is the area of a a trapezoid with the following dimensions h=5cm b1=9 cm b2= 15cm ?

e-lub [12.9K]

Answer:

60cm^2

Step-by-step explanation:

The formula for the area of a trapezium is : $\frac{a+b}{2}*height$

To work out the area of the trapezium you would first have to add the lengths at the top and bottom (a and b) which is 9+15, this gives you 24cm.

The next step is to divide the value of 24 by 2, this gives you 12cm.

The final step is to multiply the value of 12cm by the height of 5, this gives you 60cm^2. This is because if you were to substitute the values into the formula you would get the same answer.

1) Add 9 and 15.

$15+9=24$

2) Divide 24 by 2.

$24/2=12$

3) Multiply 12 and 5.

$12*5=60cm^2$
