A 5K race is about 3.1 miles. Kevin runs 3.5 miles on Monday, 4 miles on Wednesday and 1.8 miles on Friday. About how many 5K races would Kevin have completed?
Answer:
Kevin completed 3 races
Step-by-step explanation:
So to solve this first you would add up all of the miles Kevin ran.
[tex]3.5+4+1.8=9.3[/tex]
Then you would take the total amount he ran and divide it by 3.1 to see how many races he would have completed
[tex]9.3 / 3.1=3[/tex]
Solve 12x^2+5x-4=12^2x+6
Answer:
okay so we need to solve for x.
--
FIRST STEP: 12x^2+5x-4=12^2x+6 would turn into x2 + 5x - 4 = 2x + 6 so it'd have equal bases.
SECOND STEP: move any number with "x" in it to the left side. it ends up as x2 + 3x - 4 = 6
THEN, we use the AC method to eliminate any unnecessary numbers.
you should end up with ( x - 2) (x + 5) = 0
SO, the answer is your third option. ( x = 2, x = -5)
Step-by-step explanation:
Answer:
x = 2, x = -5
Step-by-step explanation:
[tex] {12}^{ {x}^{2} + 5x - 4 } = {12}^{2x + 6} \\ (Bases\: are\: equal\: so\: exponents\: \\will\:also\:be \: equal) \\ \implies \: {x}^{2} + 5x - 4 = 2x + 6 \\ \\ \implies \: {x}^{2} + 5x - 4 - 2x - 6 = 0\\ \\ \implies \: {x}^{2} + 5x - 2x - 4- 6 = 0\\ \\ \implies \: {x}^{2} + 5x - 2x - 10 = 0\\ \\ \implies \:x(x + 5) - 2(x + 5) = 0\\ \\ \implies \:(x + 5)(x - 2) = 0 \\ \\ \implies \:x + 5 = 0 \: \: or \: \: x - 2 = 0 \\ \\ \implies \:x = - 5 \: \: or \: \: x = 2[/tex]
2x + 2x + 2 = 4x + 2
Do this equation has one solution,many solutions,or no solutions?
Step-by-step explanation:
2x + 2x + 2 = 4x + 2 combine like terms
4x + 2 = 4x + 2 subtract 4x from both sides
4x - 4x + 2 = 4x - 4x + 2
2 = 2 TRUE

A photograph has a length that is 2 inches longer than its width. There is a 1-inch frame surrounding the photograph. Which expression represents the area of the entire photograph and frame combined?
The expression representing the area of the entire photograph and frame combined is A = x²+4x+3.
What is Area?Area is the amount of space taken up by a plane shape.
To find an expression for the area of the entire photograph and the frame combined, we use the formula below.
Formula:
A = L×W............. Equation 1Where:
A = Area of the photograph and the frameL = Length of the photograph and the frameW = Width of the photograph and the frameFrom the question,
Let the width of the photograph be x, The length of the photograph = (x+2) inchesL = (x+2)+1 = (x+3) inchesW = (x+1) inchesSubstitute these values into equation 1
A = (x+3)(x+1)A = x²+x+3x+3A = x²+4x+3Hence, The expression representing the area of the entire photograph and frame combined is A = x²+4x+3.

Simplify the polynomial by writing each of its term in standard form. 1.5xy^2 *(-4)xyz-4mnk*5m^2 n^3 k
The simplified polynomial by writing each of its term in standard form is:
[tex]-20m^{3}[/tex] [tex]n^{4}[/tex][tex]k^{2}[/tex] - [tex]6xy^{3z}[/tex]
What is polynomial?
A polynomial is a mathematical expression that consists of variables and coefficients, which are combined using arithmetic operations such as addition, subtraction, multiplication, and non-negative integer exponents.
To simplify the given polynomial by writing each of its term in standard form, we need to expand the products and arrange the terms in decreasing order of their degree.
First, let's expand the product [tex]1.5xy^{2}[/tex] *(-4)xyz:
[tex]1.5xy^{2}[/tex] *(-4)xyz = ([tex]-6xy^{3z}[/tex])
Next, let's expand the product -4mnk*[tex]5m^{2}[/tex] [tex]n^{3}[/tex] k:
-4mnk*[tex]5m^{2}[/tex] [tex]n^{3}[/tex]k = ([tex]-20m^{3}[/tex] [tex]n^{4}[/tex] [tex]k^{2}[/tex])
Now, we can write the simplified polynomial by adding the two terms we obtained and arranging them in decreasing order of their degree:
[tex]-20m^{3}[/tex] [tex]n^{4}[/tex] [tex]k^{2}[/tex] - 6xy^3z[tex]6xy^{3z}[/tex]
Therefore, the simplified polynomial by writing each of its term in standard form is:

What is a good estimate and the actual measurement for this angle measurement? A. 110 and 109 B. 95 and 96 C. 90 and 91 D. 70 and 71
The good estimate, as well as the actual measurement for the given angle, is 110° and 109°.
What is a good estimate?
In construction, a good estimate is an approximate value of a number that makes it faster to make cognitive deductions.
On the other hand, the actual measurement is the exact measurement of an angle or shape when the appropriate measuring tools are being used.
From the diagram, the angle is an obtuse angle because it is more than 90° since it extends more than its perpendicular axis(90°), but it is less than 180°.
Therefore, we can conclude that the good estimate, as well as the actual measurement for the given angle, is 110° and 109°.

To model the problem containing an unknown number, translate the statement into an equation.
Sixteen is five less than a number.
Which steps would you take to translate the statement?
Replace “is” with =, “less than” with –, and “a number” with n to get 16 = 5 – n.
Replace “is” with =, “less than” with +, and “a number” with n to get 16 = n + 5.
Replace “is” with =, “less than” with –, and “a number” with n to get 16 = n – 5.
Replace “is” with =, “less than” with ÷, and “a number” with n to get 16 = 5 ÷ n.
Answer:
The correct option would be the 3rd one
If you want to find 5 less than a number you are subtracting
so 5 less than 20 would be 15, so 20 - 5
since 16 is five less that means whatever the equation equals it will be 16 which is why 16 is in the first part
Answer: The correct option would be the 3rd one

X

Answer:
5
Step-by-step explanation:
12/20 = 3/x
solve for x
x=5
Answer: x is 5
Step-by-step explanation: These two triangles are similar (meaning same shape but different size.) To find x, we must first decrease the scaling. The original triangle is 3 and x sides. Being scaled, it is now 12 and 20. 12 divided by 4 is 3, so that's the first side, and being equivalent, 20 divided by 4 is 5, so therefore the triangle has been scaled by 4 units. Therefore x side is 5.
