2 birds had 14 babies. The mom kept having babies for the next 43 years. How many babies did she have
Answers
Answer:

A restaurant uses c cups of flour for baking rolls and 12 cups of flour for baking pies each day. Use the Distributive Property to write an expression for how much flour the restaurant uses in seven days.
Answers
Answer:
7c + 84
Step-by-step explanation:
To find how much flour the restaurant uses in seven days, we need to multiply the amount of flour used per day by 7. We can use the distributive property to simplify this expression by factoring out the common factor of "c + 12":
Flour used in 7 days = 7(c + 12)
Expanding the expression, we get:
Flour used in 7 days = 7c + 7(12)
Simplifying, we get:
Flour used in 7 days = 7c + 84
Therefore, the expression for how much flour the restaurant uses in seven days is 7c + 84.

In a class in a middle school, there were 80 students. 30 percent were girls. How many of the class were boys. Awnser in percents.
Answers
Answer:
In a class of 80 students 30 are girls.
To Find:
The percentage of girls in the class is?
Solution:
The given problem can be solved using the concepts of percentages.
1. The total number of students in the class is 80, 30 are girls of the 80 members.
2. Percentage is given by the formula,
=> Percentage = (Favorable numbers x 100)/Total numbers,
3. Using the formula mentioned above the percentage can be calculated,
=> Percentage of girls = (30x100)/80,
=> (30x100)/80,
=> (3x100)/8,
=> (3x25)/2,
=> 75/2 = 37.5%.
Step-by-step explanation:
Answer:
70%
Step-by-step explanation:
If 30% of the class were girls, then 70% of the class must be boys (since 30% + 70% = 100%).
To find out how many students this represents, we can use the following formula.
70/100 * 80 = 56
So there were 56 boys in the class.
To express this as a percentage, we can calculate what percentage of the class the boys represent.
56/80 * 100 = 70%
Therefore, 70% of the class were boys.

C) -32x-12
D) 2(-16x+6)

Answers
Answer:
B, D, and E
Step-by-step explanation:
-4(8x-3)= -32x+12
So we must choose the choices equivalent to this expression
A) -20x≠-32x+12
B)4(3-8x)≟-32x+12
12-32x=-32x+12
C)-32x-12≠-32x+12
D)2(-16x+6)≟-32x+12
-32x+12=-32x+12
E) 5-9(8x-3)≟-32x+12
40x-15-72x+27≟-32x+12
-32x+12=-32x+12
Can someone help? How do solve for the x's?
Answers
5x-30=4x
Move constant & collect like terms
Solution
X=30
The two angles are equal as they are vertically opposite. So, we will show that algebraically as
5x-30 = 4x
Now we solve the equation.
Subtract 4x from both sides to get 5x-30-4x=0
Now add 30 to both sides to get 5x-4x=30
Now do 5x-4x=x
X=30

5/2, or 2.5 miles
Step-by-step explanation:
Monday - 3/4 mile
Wednesday - 1/2 mile
Thursday - 2/3 mile
Saturday - 7/12 mile
Take the common denominator and add (in this case it will be 12)
9/12 + 6/12 + 8/12 + 7/12 = 30/12 = 5/2
Gio walked 2.5 miles
Answer:
She walked 2 7/12 miles.
Step-by-step explanation:
To start, we have to make sure we can add each fraction. One multiple they all have in common is 12. So we will change the denominator to 12. Remember, what you do to one side you have to do to the other!
To turn 3/4 into a 12, multiply by 3. 3x3 is 9 and 4x3 is 12 so 9/12.
To turn 1/2 into a 12, multiply by 6. 1x6 is 6 and 2x6 is 12 so 6/12.
To turn 2/3 into a 12, multiply by 4. 2x4 is 8 and 3x4 is 12 so 8/12.
And 7/12 is already in 12ths.
From there, we have to add the numerators.
9 + 6 + 8 + 7 = 31.
Now we have 31/12. We have to simplify this into a mixed number.
31 goes into 12 two times.
So we have 2 and 7/12 miles.

Group of answer choices
x = 2
x = 4

Answers
Step-by-step explanation:
Substitute the second equation into the first equation to eliminate y:
y - x = -4
-2x + 2 - x = -4 (Substitute y = -2x + 2)
-3x + 2 = -4
-3x = -6
x = 2

An image of a rhombus is shown.
a rhombus with a base of 18 centimeters and a height of 15 centimeters
What is the area of the rhombus?
66 cm2
132 cm2
135 cm2
270 cm2
Answers
Answer:
270 cm²
Step-by-step explanation:
The area of a rhombus can be calculated using the formula Area = base * height. In this case, the base is 18 centimeters and the height is 15 centimeters. So the area of the rhombus is:
Area = 18 * 15
So, Area = 270 cm².
The area of the rhombus is 270 cm².
The area of the rhombus given is; 279 cm².
What is the area of the rhombus?The area of a rhombus can be calculated using the formula;
Area = base * height.
Given that the base is 18 centimeters and the height is 15 centimeters. So the area of the rhombus is:
Area = 18 x 15
So, Area = 270 cm².
Therefore, area of the rhombus is 270 cm².
