Mathematics

Answer:≈2.67

Step-by-step explanation:

To figure this problem out, we must first figure out what a single piece of candy costs. So we take the total cost of the three candies and divide that number by the number of candies, or:

4/3,

to give us the number 1.3 repeating. This means that a piece of candy would cost $1.33. We multiply this by two to get approx. 2.67, or $2.67.

Hope that helped.

Well you have to find the cost for a single price of candy witch would be 1.33 and you would multiply that by 2 and get $2.66

Use substitution to write an equivalent quadratic equation.<br> (3x + 2)2 + 7(3x + 2) – 8 = 0
ANEK [815]
Let z = 3x+2. Then, by substitution, your equation is
.. z^2 +7z -8 = 0

_____
This equation can be factored as
.. (z +8)(z -1) = 0
.. x = -8 or +1
Then
.. 3x +2 = -8 or +1
.. 3x = -10 or -1
.. x = -10/3 or -1/3

2. A recipe says that 6 spring rolls will serve 3 people. Complete the table as you answer the questions. Be prepared to explain
LuckyWell [14K]

Answers:

a. 0.5 people

b. 10 spring rolls will serve 5 people, 16 spring rolls will serve  8 people, 25 spring rolls will serve 12.5 people

c. n/2 or 1/2 of n

Step-by-step explanation:

if 6=3p, p representing each person, then we find that 2 spring rolls serve 1 person, so 1 spring roll serves 0.5 people!

if 1=0.5p, then p is 1/2 of the amount of spring rolls.

Divide each of the amount of spring rolls by 2.

10=5p

16=8p

25=12.5p

n=n/2

The variable p is important, as to show that it's the amount of people.

Hope this helps!

How would I graph this inequality?<br> <img src="https://tex.z-dn.net/?f=7x%2B3y%5C%20%20%5Ctextless%20%5C%206-5x" id="TexFormul
Anon25 [30]

Answer:

the graph in the attached figure

Step-by-step explanation:

we have

7x+3y

isolate the variable y

Subtract 7x both sides

3y

3y

Divide by 3 both sides

y

The solution of the inequality is the shaded area below the dashed line

The equation of the shaded line is y=-4x+2

The slope of the dashed line is negative m=-4

The y-intercept of the dashed line is the point (0,2)

The x-intercept of the dashed line is the point (0.5,0)

To graph the inequality plot the intercepts and shade the area below the dashed line

using a graphing tool
