Victor baked 66 cookies with 11 scoops of flour. With 14 scoops of flour, how many cookies can Victor bake? Assume the relationship is directly proportional.

? cookies

Answers

Answer:

84 Cookies

Step-by-step explanation:

11/66= 14/x

11x=66*14

Solve for x

x=84

Answer:

84 cookies

Step-by-step explanation:

To solve this problem, we can use cross multiplication:

[tex]\frac{11}{66}=\frac{14}{x}[/tex]

66 * 14 = 924

11 * x = 11x

924 = 11x

924 ÷ 11 = 11x ÷ 11

84 = x

With 14 scoops of flour, Victor can bake 84 cookies.

Another way to solve this problem is to find how many cookies you can bake per cup of flour. To find this, divide the amount of cookies by the amount of cups of flour:

66 ÷ 11 = 6

You can make 6 cookies with 1 cup of flour.

So, to find how many cookies Victor can make with 14 cups, multiple 6 by 14:

6 * 14 = 84

Victor can make 84 cookies with 14 cups of flour.

Marcus completed five fewer passes this season than Sean. If Marcus completed 122 passes, how many did Sean complete?

Answers

Answer: 127
Reason: Marcus completed five fewer than Sean. This is put in a strange way, so we can instead say...
That Sean completed 5 more than Marcus did.
We know Marcus completed 122.
Sean completed five more then he did.
More means add, so we can say that 122 + 5 in order to get the answer.
This equals to 127.

Answer:

Answer A is Linear.  You can see this because each term is equal to the previous term plus a fixed amount (3), making it an arithmetic sequence.

Answer B is not linear.  This is because each term is a multiple of the previous one, making it a geometric sequence.

Answer:

Function A

Step-by-step explanation:

Each time x increases by 1, y increases by 3. Function B is exponential instead of linear, because y increases by a larger number each time rather than increasing by the same amount.

Answers

Step-by-step explanation: $8.4 divided by the 24 or 2 dozen dougnuts she sells means she sell each donut for $0.35 and if we know that Jane Dough sells her doughnuts for $0.15 more than what it costs her to make each doughnut then $0.35 - $0.15 = $0.20 to make each donut

Edward deposited $6,500 into a savings account 4 years ago. The simple interest rate is 5%. How
much money did Edward earn in interest?
Substitute the values into the equation.
Interest=$• • years
Edward earned $ in interest.

Answers

Answer:

Edward earned $1300 interest in 4 years.

Step-by-step explanation:

Principal Amount = Initial Investment = $6500

Time t = 4 years

Interest rate r = 5% = 0.05 (it is taken in decimal i.e 5/100 = 0.05)

We need to find interest.

The formula used is: [tex]Interest= Principal\times r \times t[/tex]

Putting values and finding Interest

[tex]Interest= Principal\times r \times t\\Interest=6500\times 0.05 \times 4\\Interest= 1300[/tex]

So, the interest = $1300 in 4 years.

Edward earned $1300 interest in 4 years.

8.) Associative Law

9.) Distributive Law

10.)

Step-by-step explanation:

The associative law means that if all the arithmetic operations in an equation are the same, the position of the brackets do not matter and no matter which variables are associated, the result would still be the same.

The commutative law means that if all the arithmetic operations in an equation are the same, the position of the variables do not matter and no matter what order the variables are placed, the result would still be the same.

The distributive law means that whatever is outside of the bracket has to be multiplied into the variables in the bracket evenly. E.g. 1/4 (8x - 20) involves multiplying both 8x by 1/4 and 20 by 1/4.

-16x-10>14-10x
hi can u please help me with this

Answers

Answer:

x < -4

General Formulas and Concepts:

Pre-Algebra

Equality Properties

Step-by-step explanation:

Step 1: Define inequality

-16x - 10 > 14 - 10x

Step 2: Solve for x

Add 16x to both sides:                    -10 > 14 + 6xSubtract 14 on both sides:              -24 > 6xDivide 6 on both sides:                   -4 > xRewrite:                                            x < -4

Here we see that any value x that is less than -4 would work as a solution.

Answer:

Step-by-step explanation:

Let's solve your inequality step-by-step.

−16x−10>14−10x

Step 1: Simplify both sides of the inequality.

−16x−10>−10x+14

Step 2: Add 10x to both sides.

−16x−10+10x>−10x+14+10x

−6x−10>14

Step 3: Add 10 to both sides.

−6x−10+10>14+10

−6x>24

Step 4: Divide both sides by -6.

−6x

What is the sum of all integers $n$ that satisfy
$$-3n < 7n-20 < 3n~?$$

$($In other words, what is the sum of all integers $n$ that satisfy both of the inequalities
$$-3n<7n-20\text{~~and~~}7n-20<3n~?)$$

If you can't figure out the latex here is a screenshot ( in the comments)

Answers

Looks like the inequality is

-3n < 7n - 20 < 3n

Add 3n to each side:

0 < 10n - 20 < 6n

Solve the right inequality.

10n - 20 < 6n

Add -10n to both sides:

-20 < -4n

Divides both sides by -4:

5 > n

Now solve the left inequality, and take the intersection of the two solution intervals.

0 < 10n - 20

Add 20 to both sides:

20 < 10n

Divide both sides by 10:

2 < n

So 2 < n < 5. There are only 2 integers in this range (3 and 4), whose sum is 7.

Answer:

7

Step-by-step explanation:

We solve each of the two inequalities separately. To solve the first inequality, -3n<7n-20, we add 3n to both sides:

0<10n-20, then we add 20 to both sides to get

20<10n. Finally, dividing both sides by 10 gives 2<n, so n must be greater than 2.

For the second inequality, 7n-20<3n, we subtract 3n from both sides:

4n-20<0, then add 20 to both sides to get

4n<20. Finally, dividing both sides by 4 gives n<5, so n must be less than 5.

The only integers that are greater than 2 and less than 5 are 3 and 4. So, the sum of all possible integer values of n is 3+4=7.
