the correct shade, how many quarts of white paint should be mixed with 8.5 quarts of blue
paint?

Answer:

X=-5

Step-by-step explanation:

Answer:

x = −5

Step-by-step explanation:

8x – 10 = 4x –30

-4x           -4x

4x - 10 = -30

    +10    +10

4x = -20

/4      /4

x = -5

Answer:

n = 73

Step-by-step explanation:

8² = x ==> x = 64

x + 12 = y ==> y = 64 + 12 = 76

y – 3 = n ==> n = 76 – 3 = 73

Answer:

2/3

Step-by-step explanation:

The way we divide fractions like this is to take the inverse of the divisor (second fraction) and multiply.  So 1/6 x 4/1 = 4/6 which reduces to 2/3.

Answer:

320 minus 7.50 p

Explanation:

the florist earned 320 dollars and then lost money due to having a competitor deliver, since we dont know the amount of people who chose competitors we use the term p next to the amount that p is worth because each time a customer uses a competitor it costs 7.50 out of the original 320.

The value of the discriminant of the given quadratic equation is 0.

The part in the formula of a quadratic equation that helps us to know the nature of the roots of a quadratic equation is known as a discriminant.

D = b² - 4ac,

Given the quadratic equation 4x² +4x + 1, if this equation is compared with the general quadratic equation. Then the value of the variables can be written as,

a = 4

b = 4

c = 1

Now, the value of the discriminant of the equation can be written as,

D = b² - 4ac

   = (4)² - 4(4)(1)

   = 16 - 16

   = 0

Hence, the value of the discriminant of the given quadratic equation is 0.

Answer:

You chose the correct option on the picture

x = -4; x = 12

Step-by-step explanation:

You solve for x by simplifying both sides of the equation, then isolating the variable.

If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.

x + 4 = 0
x − 12 = 0

Set x + 4 equal to 0 and solve for x.

Set x+4 equal to 0.

x+4=0

Subtract 4 from both sides of the equation.

x = −4

Set x − 12 equal to 0 and solve for x.

Set x−12 equal to 0.

x−12=0

Add 12 to both sides of the equation.

x=12

The final solution is all the values that make (x+4)(x−12)=0 true.

x=−4,12

Step-by-step explanation:

If you need one ask me I can try my best to explain

Answer:

number. 3 hope this helps

Explanation:

You want a tutorial and a rationale for writing numbers and doing arithmetic in bases other than 10.

For integers, an easy way to write a number in a different base is to repeatedly divide by the desired base, and list the remainders right to left.

Example 1: convert 67 to base 3:

67₁₀ = 2111₃

Example 2: convert 44 to base 3:

44₁₀ = 1122₃

The usual rules of addition apply. A sum of two digits that equals or exceeds the value of the base causes a carry to the next digit to the left. (It can be convenient to write the carries on a separate line.)

In the first attachment, the sum of the two numbers above is developed in base 3. The relevant addition facts for base 3 are ...

Of course, zero (0) is still the additive identity element.

The usual rules of subtraction apply. When a larger digit is subtracted from a smaller one, a "borrow" is indicated from the digit immediately to the left. The relevant subtraction facts for base 3 are ...

Example: 67 -44 = 23, done in base 3

For subtraction of a smaller number from a larger one, it can work well to do the computation left to right:

  2111 -1122 = ...

4th digit: 2 - 1 = 1

3rd digit: 1 - 1 = 0

2nd digit: 1 - 2 = 2 (borrow 1 from 3rd digit: 0 - 1 = 2, borrow 1 from 4th digit: 1 - 1 = 0). The difference is now 0 2 2 x

1st digit: 1 - 2 = 2 (borrow 1 from 2nd digit: 2 - 1 = 1). The difference is now ...

  2111 -1122 = 0212, done in base 3

Consider the expanded forms of the sum and difference numbers in base 3:

  11010₃ = 1×3⁴ +1×3³ +0×3² +1×3¹ +0×3⁰ = 81 +27 +3 = 111₁₀   (67+44=111)

  212₃ = 2×3² +1×3¹ +2×3⁰ = 18 +3 +2 = 23₁₀   (67-44=23)

These forms clearly show the place value of a digit position is given by the corresponding power of the number base. You see this when you write base-10 numbers in expanded form. The point is driven home by working with numbers in other bases.

In short, working with numbers in other bases gives you a better understanding of place value.

Additional comment

Fractions can be converted to a different base by multiplying the fraction by the base, then using the integer digit as the next digit to the right.

Consider 5/9 in base 3:

Then 5/9 in base 3 is 0.12

As with base 10, any fraction that cannot be written using a power of the base as its denominator will have a repeating fractional part. For example, ...

  1/10 = 0.00220022...(4-digit repeat) in base 3

Answer:

1/3

Step-by-step explanation:

4/5 + 3/15

We first find a common denominator which will be 15.

Multiplying the top and bottom of 4/5, we have 12/15

12/15 + 3/15 = 15/15 = 1

1 - 2/3 is 1/3

The value of x and y from the given parallel lines are 140° and 40° respectively.

Given that, straight line m parallel to straight line n and t is the transversal.

Vertical angles theorem or vertically opposite angles theorem states that two opposite vertical angles formed when two lines intersect each other are always equal (congruent) to each other.

Here, y°+140°=180° (Adjacent angles on straight line)

y°=40°

y°+z°=180° (Allied angles adds upto 180°)

40°+z°=180°

z°=140°

Now, x=140° (Vertically opposite angles are equal)

Therefore, the value of x and y from the given parallel lines are 140° and 40° respectively.

Step IV; Tommy must set the quadratic expression equal to 0 before factoring.

plz give brainlyest

It is found that in Step IV; Tommy must set the quadratic equations equal to 0 before factoring and then solving.

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

Given that the system of a linear equation and a quadratic equation.

2x – y = –1

x² – 5x – y = –7

Now Tommy had completed the following steps in his algebraic solution process but could not factor the resulting quadratic equation as;

x²  – 7x – 1,

Step I: y = 2x + 1

Step II: x²  – 5x – (2x + 1) = –7

Step III: x²  – 5x – 2x – 1 = –7

Step IV: x²  – 7x – 1 = –7

Therefore, we conclude that in Step IV; Tommy must set the quadratic equations equal to 0 before factoring and then solving.

Answer:

  (ii) center: (-3, 6)

  (iii) A(-3, 6-√51), B(7, 6), D(-3, 6+√51), H(-13, 6)

  (iv) (x +3)²/100 +(y -6)²/51 = 1

Step-by-step explanation:

(ii) The center is the midpoint between the foci:

  center = ((-10, 6) +(4, 6))/2 = (-10+4, 6+6)/2

  center = (-3, 6)

__

(iii) The vertices are the center plus or minus the semi-major axis length in the x-direction: (-3±10, 6).

The semi-minor axis length is the root of the difference of squares of the semi-major axis and the center-focus distance:

  semi-minor axis = √(10² -7²)

  semi-minor axis = √51

So, the co-vertices are the center plus or minus this value in the y-direction: (-3, 6±√51)

Using the labeling in the drawing the various points are ...

  A(-3, 6-√51), B(7, 6), D(-3, 6+√51), H(-13, 6)

__

(iv) For center (h, k) and semi-axis lengths 'a' and 'b' the equation of an ellipse is ...

  (x -h)²/a² +(y -k)²/b² = 1

For the center and axes here, the equation is ...

  (x +3)²/100 +(y -6)²/51 = 1
