How do you factor 8x+56?

2 answers:

8 0

If you mean how do you get x by it's you divide both sides by 8, to cancel out the multiplication between x and 8, meaning that it would end up being x=7, sorry if that didn't answer your question correctly.

Divide 56 by eight (=7)
Divide 8x by eight (=X)
So you have X + 7
So I think it would be 1(x+7)

(I could be wrong)

Three orders are placed at a pizza shop. two small pizzas, a liter of soda, and a salad cost $14; one small pizza, a liter of so

mojhsa [17]

To determine the cost of each item, we need to set up equations. From the problem statement, we have three unknowns so we need three equations. We set up equations as follows:

let x cost of small pizzas
y cost of soda
z cost of salad

two small pizzas, a liter of soda, and a salad cost $14
2x + y + z = 14

one small pizza, a liter of soda, and three salads cost $15

x + y + 3z = 15

three small pizzas, a liter of soda, and two salads cost $22
3x + y + 2z = 22

Solving for x, y and z, we will have:

x = $ 5
y = $ 1
z = $ 3

A kite is flying 20 ft off the ground. Its line is pulled taut and casts a 15 ft - shadow. Find the length of the line. If neces

Kryger [21]

Answer:

The answer to your question is 25 ft

Step-by-step explanation:

Data

height = 20 ft

leg = 15 ft

length of the line = ?

To solve this problem use the Pythagorean theorem.

Height = short leg = b

leg = long leg = a

length of the line = hypotenuse = c

- Substitution

c² = (20)² + (15)²

-Simplification

c² = 400 + 225

c² = 625

-Result

c = $\sqrt{625}$

c = 25 ft

ratelena [41]

Answer:

$10\frac{11}{20}$

Step-by-step explanation:

$5\frac{1}{2} + 3\frac{4}{5} + 1\frac{1}{4}$

1.Find the LCM(Least Common Multiple).

That would be 20.

2.Multiply so all denominators are equal.

$5\frac{10}{20} + 3\frac{16}{20} + 1\frac{5}{20}$

3. Add

$9\frac{31}{20}$

4. Simplify

$10\frac{11}{20}$
