Answer:

15

Step-by-step explanation:

divided 30 by 2 only work for the 50%

Oh i think this is wrong but i tried sorry

Answer:

$15 :)

Step-by-step explanation:

You have to move the decimal 2× to the left on the 15%, then multiply it by $30 ♡

Step-by-step explanation:

5(x- 2) - y(2-x)

5(x- 2) - -y(x-2)

5(x- 2) + y(x-2)

=(5+y) (x-2)

Answer:

695/kph

Step-by-step explanation:

Divide the kilometers (3475) by the number of hours (5)

to get 695

Answer:

angle 4 = 115°[vertically opposite angles]

angle 2+ angle 4=180°[linear pair]

angle 2+ 115 = 180°

angle 2 = 180°-115°

angle 2=65°

angle1+angle2+80°=180°[sum of all angles is 180°]

angle1+65°+80°=180°

angle 1 + 140° = 180°

angle 1=180°-140°

angle1 =40°

angle2= angle5[vertically opposite angles]

angle7+angle5+61°+90°=360°[sum of all angles of quadrilateral is 360°]

angle7+ 65°+ 61° +90°=360°

angle7+ 211°=360°

angle7=360°-211°

angle7=149°

angle7+angle6=180°[linear equation]

149°+angle6=180°

angle6=180°-149°

angle6=31°

angle4+angle6+angle3= 180°[by sum of all angles is 180°]

115°+31+angle3=180°

146°+angle3=180°

angle3=180°-149°

anble3=41°

Answer:

It is true because 3/6 is that smallest fraction or "simplest form" of 6/12

Step-by-step explanation:

Answer:

Step-by-step explanation:

minus 12 on both sides

Answer:

y = -4x + 9

Step-by-step explanation:

Slope intercept form is:

y = mx + b

If m = -4

y = -4x + b

Plug the values of the first set of coordinates into this:

y = -4x + b

-3 = -4(3) + b

-3 = -12 + b

Add 12 to both sides of the equation to isolate b:

-3 + 12 = -12 + b + 12

9 = b

So that makes the slope intercept form:

y = -4x + 9

Hope this helps!

Answer:

Statement should be : "4 less than the product of 3 and some number x is y" => 3x-4 = y

Step-by-step explanation:

Let "Four less than the product of three and n"

From the given statement we get an algebraic expression 3x - 4 = y.

An algebraic expression in mathematics exists as an expression that stands created up of variables and constants, along with algebraic operations like addition, subtraction, etc. x exists a variable, whose value exists unspecified to us and can take any value.

An algebraic expression exists as an indication acquired by a finite number of the fundamental operations of algebra upon characters symbolizing numbers.

Answer:

(x + y) : (2x-3y) = - 7/11

Step-by-step explanation:

The ratio is denoting:

x = 2

y = 5

Substitute your values into the equation's variables (x and y). Then solve.

(x + y) : (2x-3y)

(2 + 5 ) : [2(2) - 3(5) }

7 : [4-15]

7: -11

ratios can be turned into fractions.

7: -11 is the same thing as - 7/11

Answer:

1/10

Step-by-step explanation:

your equation is 4/5 divided by 8/1.

Lets solve that problem with the acronym KCF, or

Keep

Change

Flip.

K: "keep" the first fraction, or the one you are multiplying with, so 4/5 stays the same.

C: "change" the division sign to a multiplication sign, so 4/5x8/1

F: "flip" the second fraction, so 8/1 becomes 1/8.

now our equation is 4/5x1/8. If we solve that, we get 4/40, which reduced is 1/10.

Step-by-step explanation:

Scatter plots' primary uses are to observe and show relationships between two numeric variables. ... Relationships between variables can be described in many ways: positive or negative, strong or weak, linear or nonlinear. A scatter plot can also be useful for identifying other patterns in data.

For height of garden we can use Phytagoreaan Theorem :

h² = 25² - 7²

h² = 625 - 49

h² = 576

h = 16 m

Area

= 1/2 × base × height

= 1/2 × 14 m × 16 m

= 7 m × 16 m

= 112 m²

Answer:

Step-by-step explanation:

0.167

Step-by-step explanation:

5 ÷ 29.95

= 5 ÷ 2995/100

= 5 × 100/2995

= 500/2995

≈ 0.167

You can find the mean of negative numbers just the same as for positive numbers. It doesn't hurt for the mean to be negative.

For example, with the number -9, -5, -4, -3, -1 you can find the mean jsut as any other numbers

-9+-5+-4+-3+-1=-22

-22/5=-4.4

the mean for those set of numbers is -4.4
