Answer:
Mandy sold 250 pancakes and 50 waffles.
Step-by-step explanation:
From the information given, you can say that the sum of pancakes and waffles is equal to 300:
x+y=300
Also, the statement indicates that she charges $3 per pancake, $1 per waffle, and made a total of $800 and you can express this as:
3x+y=800
You have the following equations:
x+y=300 (1)
3x+y=800 (2), where:
x is the number of pancakes she sold
y is the number of waffles she sold
Now, you can solve for x in (1):
x=300-y (3)
Then, you can replace (3) in (2):
3(300-y)+y=800
900-3y+y=800
900-800=2y
100=2y
y=100/2
y=50
Finally, you can replace the value of y in (3) to find x:
x=300-50
x=250
According to this, the answer is that Mandy sold 250 pancakes and 50 waffles.

3x - 31 = x + 59
Answer:
Let's solve your equation step-by-step.
3x−31=x+59
Step 1: Subtract x from both sides.
3x−31−x=x+59−x
2x−31=59
Step 2: Add 31 to both sides.
2x−31+31=59+31
2x=90
Step 3: Divide both sides by 2.
2x

x=45
Answer:
x=45
Step-by-step explanation:
Answer:
x=45
Step-by-step explanation:
3x - 31 = x + 59
Both side -x
3x-x-31=x-x+59
3x-x -31=59
Both side +31
2x-31+31=59+31
2x=90
Both side divide 2
x=45

Select the correct answer. A school administrator wants to know the average age of the 25,000 kindergarteners in her state at the beginning of the school year. She randomly selects 1,000 kindergarteners in the state, assuring that the group accurately represents all kindergarteners in the state, and finds the average age to be 5 years 10 months. What assumption can she make regarding the approximate average age of all kindergarteners in the state? A. The approximate average age of kindergarteners in the state is less than 5 years 10 months. B. The approximate average age of kindergarteners in the state is 5 years 10 months. C. The approximate average age of kindergarteners in the state is greater than 5 years 10 months. D. No assumptions can be made regarding the average age of kindergarteners in the state because the sample is biased.
Answer:
The approximate average age of kindergarteners in the state is 5 years 10 months.
Step-by-step explanation:
The assumption that the school administrator can make is as follows:
B. The approximate average age of kindergarteners in the state is 5 years 10 months.What is an assumption?An assumption is a statement that declares the existence of the relationship between two or more variables.
Using a sample as the school administrator did can help an assumption to be proved practically.
Thus, the assumption that the school administrator can make regarding the approximate average age of all kindergarteners in the state is Option B.

Answer:
x = 87
Step-by-step explanation:
The angles you see have a Corresponding Relationship so they are equal
x+15=102
x+15-15=102-15 (subtract 15 from both sides)
x=102-15

Find the missing length.
a
2.1 cm
2.9 cm
I NEED HELPPPP PLSSSS ITS FOR A MASTERY TEST PLSSSS HELPPPP
Answer:
a = 2
Step-by-step explanation:
To find the missing length we can use the Pythagorean theorem. Also, because it's a right triangle it makes it the perfect candidate!
The Pythagorean Theorem states:
a^2 + b^2 = c^2
Next, we substitute the letters with our given numbers (keep in mind that c is the hypotenuse which is the side facing the right angle)
a^2 + 2.1^2 = 2.9^2
Finally, we solve our equation (hint: use the calculator if needed)
a^2 = 4 (your answer is not final yet. You have to take the square root of both numbers)
a = 2 (Now that's the final answer!)
Solve for x in simplest form 3 = 5/2 (3x - 2)

$450.00
$450.40
$45,000.40
$45,040.00
Answer:
Fv = future value
Pv = present value
Fv = Pv (1+ it)
= $5,630( 1+0.04 (2))
= $6080.4
Fv = Pv + interest
$6080.4 = $5,630 +interest
interest = $6080.4 - $5,630 = $450.40

how does the Torah affect Jewish life today !!!!!!!
i will give brainlisttttt
Answer:
the Torah plays a big part in the lives of Jews today as it is believed to be the word of God. All Jews use the Torah to help guide them in their lives, but some Jews use the Torah more strictly than others. For example, some Orthodox Jews believe that it is important to follow every single rule in the Torah. However, Reform Jews tend to follow the rules they feel are most important and disregard some rules they see as outdated.
The significance of the Torah is seen in many ways:
It is read aloud weekly at the synagogue. It takes a year to recite the whole Torah.
The festival of Shavout celebrates God’s revelation of the Torah to Moses.
The commandments in the Torah shape the way that Jews live their lives today.
