% means (/100)
[tex] \frac{7}{100} \times 20 \\ \\ = \frac{140}{100} = \frac{14}{10} \\ = 1.4[/tex]
Is x=-3 a solution of the equation 2x+4=8+x? Show work
For pre algebra
Answer:
x= 4 is a solution
Step-by-step explanation:
Answer:
When x = -3 is given, all you need to do is substitute and check if the answers in LHS and RHS are equal.
2x+4=8+x
2(-3)+4=8+(-3)
-6+4=8-3
-2 [tex]\neq[/tex] 5
NO SOLUTION
Write the steps to solving the following problem.
4 - 3x = -1
Step 1:
Step 2:
Step 1: Add 3x to both sides to get 4 = 3x - 1
Step 2: Add 1 to both sides to get 5 = 3x
Step 3: Divide by 3 on both sides to get 5/3 = x
Answer:
x = [tex]\frac{5}{3}[/tex] or [tex]1 \frac{2}{3}[/tex]
Step-by-step explanation:
Isolate the variable x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction.
~
Step 1:
Subtract 4 from both sides of the equation:
4 (-4) - 3x = -1 (-4)
-3x = -1 - 4
-3x = - 5
Step 2:
Divide -3 from both sides of the equation:
(-3x)/-3 = (-5)/-3
x = -5/-3
x = 5/3
x = 1 2/3

Step-by-step explanation:
The way that I'm going to do it it's not the traditional
[tex]238\cdot13\\\\\longrightarrow 13=10+3\\\\\Rightarrow 238\cdot(10+3)\\\\=238\cdot(10)+238\cdot(3)\\\\=2380+238\cdot (3)\\\\=2380+(200+30+8)(3)\\\\=2380+(200)(3)+(30)(3)+8(3)\\\\=2380+600+90+24\\\\=2980+90+24\\\\=3004+90\\\\=3094[/tex]

Answer:
c. x = 1
Step-by-step explanation:
c. The Pythagorean theorem applies. The square of the hypotenuse is the sum of the squares of the other two sides.
2² = x² +(√3)²
4 = x² +3
1 = x² . . . . . . subtract 3
1 = x . . . . . . . take the square root

Trent is drawing a diagram of his house for a school project. He decides that every 5 feet in real life should be 2 inches in the diagram. Trent's living room is 15 feet long. How long should Trent's living room be in his diagram?
Answer:
5 feet (60 inches) proportional to 2 inches is a 30:1 relationship.
15 feet (180 inches) in real life should equal 6 inches on the diagram.
180 divided by 30 = 6
Step-by-step explanation:
Answer:
6 inches

As part of an energy savings initiative, residents in a small town were able to decrease their annual household electricity consumption to an average of 10,800 kilowatt-hours (kWh). If
the new average household consumption is less than the original average, what was the average annual household electricity consumption prior to the initiative?
Answer: 2/5
Step-by-step explanation:
You have to work it out
You start at (10, 1). You move down 1 unit and left 7 units. Where do you end?
Translation in right or left causes the x coordinate to change while translation in up or down causes the y coordinate to change.
Moving left or down causes the coordinates to be going negative.
Moving right or up causes the coordinates to be positive.
Original point (10, 1).
Down 1 unit:
(10, 1 - 1) = (10, 0)
Left 7 units:
(10 - 7, 0) = (3, 0)
You end at (3, 0)
Solve for a : -2a-7a=0
a=0 this is your answer

In rectangle FGHK, FC = CH = 8.5 cm. What is the area of rectangle FGHK?
8.5 cm
15cm^2
120cm^2
125.5cm^2
Answer:
we have the width is 8 cm and the diagonal line is 17 cm so to get the length you're going to use Pythagoras theorem so 8 centimetres will be represented by a 17cm will be represented by c then length will be represented by b so b squared is equals to c squared minus a squared say 17 squared - 8 squared 17 squared is 289 while 8 squared is 64 the result will be 225 so b squared is equals to 225 to get b we will get the square root so b is equals to 15 so our length is 15 the area is equals to length x width so 15 * 8 you get 120 square centimetres
120 square centimeters is the area of rectangle FGHK.
What is area of a rectangle?Area of a rectangle (A) is the product of its length (l) and width (w).
here, we have,
from the given figure,
we have the width is 8 cm and the diagonal line is 17 cm
so to get the length you're going to use Pythagoras theorem
so 8 centimeters will be represented by a
17cm will be represented by c
then length will be represented by b
so b squared is equals to c squared minus a squared
say 17 squared - 8 squared
17 squared is 289 while 8 squared is 64
the result will be 225
so b squared is equals to 225
to get b we will get the square root
so b is equals to 15
so our length is 15
the area is equals to length x width
so 15 * 8
you get 120 square centimeters.
hence, 120 square centimeters is the area of rectangle FGHK.

help
Answer:
x = 118/7 or 16.86
Step-by-step explanation:
Assuming these are supplementary like you showed in the picture,
59 + 3 + 7x = 180
subtract 62 from both sides
7x = 118
divide by 7
x = 16.86
If they are complementary, x = 4
I hope this helps!
Fred and Matt are playing basketball. If x represents the points Matt ended with, and 3x represents the points Fred ended with, what does that tell you about the relationship between Matt and Fred’s points?
It tells you that Fred has three times the score more than Matt.
This is because Matt has x points, Fred tops Matt by 3x points.

Answer:
No integers are irrational.
Step-by-step explanation:
Think about the real number system, whole numbers contain natural numbers, integers contain whole numbers, rational numbers contain integers, and real numbers contain all of these including irrational numbers. An irrational number is separate from the rest of the real numbers because it cannot be expressed or written as a fraction or decimal.
