Answer: 79
Step-by-step explanation: Lets first deal with the X. The equation would be 3 X 3 X 9. This answer is 81. Next we have 81 - 2. Therefore, our answer is 79. Do multiplacation first as M is before S in peMdaS.
Answer:
79
Step-by-step explanation:
x = 3y and y = 9
This means x = 3*9 = 27
3x -2
3 * 27 -2

Jacque needs to buy some pizzas for a party at her office. She's ordering from a restaurant that charges a $ 7.50 $7.50dollar sign, 7, point, 50 delivery fee and $ 14 $14dollar sign, 14 per pizza. She wants to buy as many pizzas as she can, and she also needs to keep the delivery fee plus the cost of the pizzas under $ 60 $6
Answer:
5 pizzas Sorry i may be wrong
Step-by-step explanation:
The inequality that models this situation is given by:
[tex]7.5 + 14p \leq 60[/tex]
--------------------------------
The first step towards building the inequality is finding Jacque's total spending.The delivery, which if a fixed fee(paid only once), is $7.50.Then, each pizza will cost $14, thus, the cost of buying p pizzas is [tex]14p[/tex].Thus, the total spending is of:[tex]T = 7.5 + 14p[/tex]
--------------------------------
He wants the cost under $60, and thus:[tex]T \leq 60[/tex]
Since [tex]T = 7.5 + 14p[/tex], the inequality is:
[tex]7.5 + 14p \leq 60[/tex]

Sakura buys some softballs at $3 each and bats at $35 each for her PE class.
She buys twice as many balls as bats. She spends $131 in total, which
includes $8 tax. Which equation would you use to find the number of bats she
buys?
Let x represent the number of bats she buys.
Given :
Cost of each ball , $3.
Cost of each bat , $35 .
Total money spend , $131 .
She buys twice as many balls as bats.
Tax , $8 .
To Find :
The number of bats she buys .
Solution :
Let , x represent the number of bats she buys.
So , number of balls she buys is 2x .
[tex]35x+3(2x)+8=131\\\\35x+6x=123\\\\41x=123\\\\x=3[/tex]
Therefore , number of bats she buys is 3 .
Hence , this is the required solution .

Combining like terms
2 + 3x - X=4x
Answer:
Hi there!
Your answer is:
x= 1
Step-by-step explanation:
Goal- get all X's on one side, and all whole numbers on the other
2+3x -x = 4x
First, combine like terms on each side of the equal sign
2+ 2x = 4x
Next, think about the additive inverse property. What, added to 2x, equals 0? 2x + (-2x) =0! So, we subtract 2x from both sides!
2= 4x-2x
Simplify
2= 2x
Divide both sides by the coefficient of x (in this case, 2)
2/2 = x
2/2 is equal to 1
1= x
Hope this helps!
Answer:
x = 1
Step-by-step explanation:
Combining the x terms, we get
2 + 2x = 4x, or 2 = 2x.
Then, after we divide both sides by 2 to isolate x, we get x = 1

The tree diagram shows all the possible combinations for heads (H) and tails (T) when 3 coins are tossed. What is the probability that the outcome has at least two heads?
Answer:
No diagram so I'll make one:
H H H
H H T
H T H
T H H
T T H
T H T
H T T
T T T
There are 8 possible outcomes and four of these have 2 heads.
Probability = 4 / 8 = .50
Step-by-step explanation:
Probability of getting at least two heads after tossing 3 coins is equals to (1 / 2).
What is probability?" Probability is defined as a mathematical statement which represents the ratio of number of favourable outcomes to the total number of outcomes."
Formula used
Probability = [tex]\frac{Number of favourable outcomes}{Total number of outcomes}[/tex]
According to the question,
Number of coins tossed =3
As shown in the tree diagram drawn we have,
Total number of outcomes = 8
At least two heads means 2 or more than two
Here.
HHH, HHT,HTH, THH
Number of favourable outcomes of getting at least two heads = 4
Substitute the value in the formula of probability we get,
Probability = (4 / 8)
= ( 1 / 2)
Hence, probability of getting at least two heads after tossing 3 coins is equals to (1 / 2).

difference of two numbers is 166. The sum of the same two numbers is 234. What are the two numbers?
Answer:
The numbers are 100 and 234Step-by-step explanation:
Let the numbers be x and y
The statement
difference of two numbers is 166 is written as
x - y = 166.......... Equation 1
The sum of the same two numbers is 234 is written as
x + y = 234 ............. Equation 2
Solve the equations simultaneously
Add both equations 1 and 2
That's
x + x + y - y = 166 + 234
2x = 400
Divide both sides by 2
x = 100Substitute the value into the first equation
That's
100 + y = 234
y = 100 - 234
y = 134The numbers are 100 and 234Hope this helps you

Some rational numbers are whole numbers. True or False
Answer:
False
Step-by-step explanation: A rational number is any number can be expressed as a fraction. Whereas, a whole number is a positive number without a decimal or fractions. Every rational number is may or may not be a whole number.
The statement "Some rational numbers are whole numbers" is:
True
Some rational numbers are whole numbers. True or False?A rational number is any number that can be expressed as a fraction of two integers, where the denominator is not zero. A whole number is any integer that is not negative.
All whole numbers are rational numbers. This is because any whole number can be expressed as a fraction with a denominator of 1.
For example, the whole number 3 can be expressed as the rational number 3/1.
However, not all rational numbers are whole numbers. For example, the rational number 1/2 is not a whole number, because it cannot be expressed as a fraction with a denominator of 1.
Therefore, "Some rational numbers are whole numbers" is True.
