2c + 5 + (15+10) 3 = 120

step by step please !!

2c + 5 + (15+10) 3 = 120 Step By Step Please !!

Answers

Answer 1
Ok so I’m not sure but this is how we solve it in the way I learned.
-You add and simplify the equation first so it will be
2c + 20(3) = 120
2c + 60 = 120
-Then you subtract the 60 by itself and then the 120 and it leaves you with
2c = 60
-lastly you divide
2c/2 = 60/2
Then you find your answer is 30
C = 30
Answer 2

Answer:

solve for c

c = 20

Step-by-step explanation:

2c + 5 + 25 x 3 = 120

2c + 5 + 75 = 120

2c + 80 = 120

2c = 120 - 80

2c = 40

c = 20

At a local bakery, Emily buys 6 cookies for $4.50. Each of the cookies costs the same amount.

Which equation represents the price, P, in dollars of c cookies?

P=c0.75


P=0.75c


P=c6


P=6c

Answers

Answer:

I don't know

Step-by-step explanation:

The correct equation to represents the price P in dollars of c cookies will be;

⇒ P = $0.75c

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The cost of 6 cookies = $4.50

Now,

Since, The cost of 6 cookies = $4.50

Hence, The cost of 1 cookies = $4.50/6

                                              = $0.75

So, We can formulate;

The cost of c cookies = $0.75c

Hence, The equation to represents the price P in dollars of c cookies is;

⇒ P = $0.75c

Thus, The correct equation to represents the price P in dollars of c cookies will be;

⇒ P = $0.75c

Step-by-step explanation:

Step 1: Define

Point (2, 6)

Point (1, 9)

Step 2: Find slope m

Substitute:                    [tex]m=\frac{9-6}{1-2}[/tex]Subtract:                       [tex]m=\frac{3}{-1}[/tex]Divide:                           [tex]m=-3[/tex]

Answer:

-3

Step-by-step explanation:

The equation for the slope is the change in y/ the change x.

In order to find the change in y we have to subtract the second y (9) by the first y(6) and do the same for x.

That will be (9 - 6)/(1 - 2) = 3/-1 = -3

Slope is -3

Step-by-step explanation:

You have the following expression:

x^2 + 3x

In order to determine the value of the previous expression for x = 1.7, replace this value into the previous expression and simplify:

(1.7)^2 + 3(1.7) = 2.89 + 5.1 = 7.99

Hence, the result is 7.99

Find the slope...........

Answers

First thing to do is find out the coordinates of two points on the graph (I will use the ones that have been marked by the red dots):

Point A: (3, -1)
Point B: (1, 2)

Then we will use the slope formula to work out the slope:

y₂ - y₁ / x₂ - x₁

Substitute in our points:

2 - (-1) / 1 - 3

Then we work out the expression (remember a negative and a negative make a positive!):

3 / -2

Then we check if we can simplify this fraction, which in this case we cannot.

Therefore the slope of that line would be:

3 / -2

(remember to write it as a fraction!)

Terri buys five and seven eighths ounces of chocolate chips. She uses four and four sixths ounces in a recipe. How many ounces of chocolate chips does she have left?

a one and ten forty eighths ounces
b one and three fourteenths ounces
c two and ten forty eighths ounces
d two and three fourteenths ounces

Answers

Answer:

(A) [tex]1\frac{10}{48}[/tex]

Step-by-step explanation:

To find how many chocolate chips are left, you have to subtract the amount used for the recipe from the original amount which is:

[tex]5\frac{7}{8} -4\frac{4}{6}[/tex]

To subtract the two mixed numbers, first you have to convert them to improper fractions which would make the expression:

[tex]\frac{47}{8}-\frac{28}{6}[/tex]

Then, in order to subtract the two improper fractions, since they have different denominators, you have to make them have the same denominator. The LCM (Least Common Multiple) of 8 and 6 is 24, so to subtract the two fractions, you need both of them to have a denominator of 24. That would make the expression:

[tex]\frac{141}{24}-\frac{112}{24}[/tex]

To subtract these two fractions, since they have the same denominators, you can subtract the numerators and keep the denominators. That would make the answer:

[tex]\frac{29}{24}[/tex] which is, as a mixed number, [tex]1\frac{5}{24}[/tex], which is [tex]1\frac{10}{48}[/tex].
