Answer:
(3x-1) + (3x-1) + (2x+1) = 55
Step-by-step explanation:
1. 3x + 3x + 2x = 8x
2. -1 + -1 + 1 = -1
3. 8x -1 = 55
4. 8x = 55 + 1
5. 8x = 56/8
6. x = 7
find three consecutive integers whose average is 20. please show work!!
Answer:
19,20,21
Step-by-step explanation:
The average is 20. The numbers can be written as: 20+a, 20 +b, 20+c, with a, b, c integers (positive and negative, but higher than - 19),with a+b+c =0.
You have to find the combination a, b, c with the smallest positive integer as its higher number.
Obviously, you start with 1, and find - 1,0,+1 as a suitable solution.
Therefore, the numbers are 20-1, 20,20+1
=> 19,20,21

Answer:
B. y = 5x
Step-by-step explanation:
there are 2 coordinates (0,0) and (3,15)
slope m = (y2-y1)/(x2-x1)
m = (15 - 0)/(3 - 0) = 15/3 = 5
Using y = 0, x = 0, m - 5
y = mx + b
0 = 5(0) + b
b = 0
=> y = 5x
Stefanie is painting her bedroom. She can paint 12 2/3 square feet in 2/5 of an hour. How many square feet can she paint in one hour?
Answer:
[tex]31\frac{2}{3}[/tex]
Step-by-step explanation:
since its only 2/5 of 1 hour, two 2/5 equal 4/5 so we divide the 12 2/3 by 2 to find the 1/5 which is 6 1/3
[tex]12\frac{2}{3}[/tex]÷2=[tex]6\frac{1}{3}[/tex]
[tex]12\frac{2}{3} +12\frac{2}{3}=25\frac{1}{3}[/tex]
[tex]12\frac{1}{3} +6\frac{1}{3}=31\frac{2}{3}[/tex]
WHAT IS 3 x 19 x 14 + 18 DIVIDED BY 2 ( USING PEMDAS, GEMDAS)
Answer: 807
Step-by-step explanation:
3 x 19 x 14 + 18 ÷ 2
Multiply 3 and 19.
57 x 14 + 18 ÷ 2
Multiply 57 and 14.
798 + 18 ÷ 2
Divide 18 by 2.
798 + 9 = 807.
The value of the expression 3 x 19 x 14 + 18 divided by 2 will be 807.
What is PEMDAS?
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
The given expression 3 x 19 x 14 + 18 ÷ 2 will be calculated by the PEMDAS rule as follows:-
Multiply 3 and 19.
57 x 14 + 18 ÷ 2
Multiply 57 and 14.
798 + 18 ÷ 2
Divide 18 by 2.
798 + 9 = 807.
Therefore, the value of the expression 3 x 19 x 14 + 18 divided by 2 will be 807.

The age of the oldest sibling is 15 years old.
What is consecutive number?
Numbers that follow each other continuously in the order from smallest to largest are called consecutive numbers.
Here, let the age of youngest sibling be x years
the age of middle sibling be (x+1) years
the age of oldest sibling be (x+2) years
According to question,
x + (x+1) + (x+2) = 42
3x + 3 = 42
3x = 39
x = 13
Thus, the age of the oldest sibling is (x+ 2) years = 15 years old.

On Morgan’s math quiz, he was asked to simplify the expression 4(3x + 2y + x – 4). His answer was 12x + 8y + 4x – 16. Which best describes Morgan’s error, and what is the correct answer?
A. Morgan used the distributive property correctly, but now he must combine like terms. The correct answer is 24xy – 16.
B. Morgan used the distributive property correctly, but now he must combine like terms. The correct answer is 16x + 8y – 16.
C. Morgan did not use the distributive property correctly because the last term should be positive. The correct answer is 12x + 8y + 4x + 16.

Answer:
0.972x
Step-by-step explanation:
x - 0.1x + 0.08(0.9x)
Converting percentages to decimals has you divide the percentage by 100.
So our first equation is full price minus a tenth of that price, leaves you with nine tenths, right? Then we multiply that nine tenths by 8 percent, which is 8 hundredths.
0.9x + 0.072x = 0.972x
