Jane Dough sells her doughnuts for $0.15 more than what it costs her to make each doughnut. If you can buy 2 dozen doughnuts for $8.40, how much does it cost Jane to make each doughnut?
Answer: $0.20
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

-16x-10>14-10x
hi can u please help me with this
Answer:
x < -4
General Formulas and Concepts:
Pre-Algebra
Equality PropertiesStep-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 < -4Here 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

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
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.

Which statement is true about a shape and its dilation? A.The corresponding angles of a shape and its dilation are congruent. B.The corresponding angles of a shape and its dilation are not congruent. C.The side lengths of a dilation are always smaller than the corresponding side lengths of the original shape. D.The corresponding side lengths of a shape and its dilation are congruent.
Answer:
A.The corresponding angles of a shape and its dilation are congruent.
Step-by-step explanation:
Dilation is a type of rigid transformation in which the dimension of a shape is either increased or decreased to produce its image. It involves a change in the dimensions of the shape by a required factor. In the process, the side lengths of the image are different to the original lengths. But the angles are not affected.
Thus, the respective angles of the given shape and its image are the same.
The appropriate answer to the given question is A.

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.
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.
A prime number has two factors, itself and 1? *
Answer:
That is true. More information below.

A prime number has to have only two factors: 1 and itself. 1 only has one factor (itself) so it is, as you were saying, neutral.

Solve for x: 3 - (2x - 5) <-4(x + 2)
Answer:
x < -8
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define
3 - (2x - 5) < -4(x + 2)
Step 2: Solve for x
Distribute: 3 - 2x + 5 < -4x - 8Combine like terms: -2x + 8 < -4x - 8Add 4x on both sides: 2x + 8 < -8Isolate x term: 2x < -16Isolate x: x < -8Here we see that any value x smaller than -8 would work as a solution in the inequality.

X = -4
Kevin graphed the inequality x > 1.
A number line going from negative 3 to positive 5. A closed circle is at 1. Everything to the right of the circle is shaded.
What mistake did Kevin make? Explain.
.
Answer:
Sample: Kevin should have used an open circle on 1, not a closed circle. The closed circle means that 1 is included in the solution set, but the inequality is x > 1, so 1 is not part of the solution.
Mistake done by Kelvin is he used closed circle at 1 where inequality x > 1 which excludes 1.
What is open and closed circles?
" Closed circle represents that the value is included in the given range while that of open circle represents given number is not included."
According to the question,
Graph of inequality x > 1 represents all values greater 1 excluding 1.
Number line represents -3 to 5.
A closed circle at 1 means 1 is included.
As per the condition of inequality x > 1 , 1 is excluded while in closed circle 1 is included both are contradictory conditions.
Hence, mistake done by Kelvin is he used closed circle at 1 where inequality x > 1 which excludes 1.
