5(x – 4) = 3x + 4
A x = -8
(B) x = -2
C x=3
(D) x = 12
Math

Answers

The answer is D.

The first step is to use the distributive property and turn 5(x-4) into 5x - 20.
You then move the twenty into the right equation by adding 20 to both sides. The final step is to move the 3x into the left equation by subtraction and then dividing both sides by 2 to isolate x. Hope this helped !!

Answer:

D

Step-by-step explanation:

5(x-4) = 3x + 4

5x-20 = 3x + 4

5x-3x-20= 4

2x=4 +20

2x=24

x=12

check answer by inserting 12 for x into original  equation.

Can someone help me with this please asap

Answers

Answer:

The answer is 4

Step-by-step explanation:

because all of the angles need to add up to 180 so 17 x 4 is 68 and 68 - 8 = 60 and 60 x 3 = 180 so the answer would be 4

Answer:

4

Step-by-step explanation:

Since all the sides are congruent, so is the angles and in a triangle all angles add up to 180. To find the angle of one of them divide 180 by 3 which is 60.

Then put the equation equal to 60

17x - 8 = 60

17x = 68

x = 4

Can someone put this into vertex form?
y=x2+24x-15

Answers

Answer:

The vertex form of y = x² + 24x - 15 is y = (x + 12)² - 159

Step-by-step explanation:

The vertex form of the quadratic equation y = ax² + bx + c is

y = a(x - h)² + k, where

a is the coefficient of x²(h, k) are the coordinates of the vertex pointh = [tex]\frac{-b}{2a}[/tex] , where b is the coefficient of xk = y at x = h

Let us use the facts above to solve the question

y = x² + 24x - 15

∵ a is the coefficient of x² and b is the coefficient of x

a = 1 and b = 24

∵ h is the x-coordinate of the vertex point

∵ h = [tex]\frac{-b}{2a}[/tex]

→ Substitute the values of a and b to find h

∴ h = [tex]\frac{-24}{2(1)}=\frac{-24}{2}[/tex]

h = -12

→ To find k substitute y by k and x by h

∵ y = k and x = h

∴ k = (-12)² + 24(-12) - 15 = 144 - 288 - 15

k = -159

∴ The coordinates of the vertex point are (-12, -159)

→ Substitute the values of a, h, and k in the vertex form above

∵ y = 1(x - -12)² + (-159)

→ Remember (-)(-) = (+) and (+)(-) = (-)

y = (x + 12)² - 159

The vertex form of y = x² + 24x - 15 is y = (x + 12)² - 159

Nathan spins 2 different spinners at the same time. There are a total of 10 possible outcomes. Which pair of spinners did Nathan spin? A B 1 2. AB E с 5 3 E с 1 2 D 4 D А B B 1 2 care 1 2 E с D с D 3​

Answers

Answer:

Since the spinners have been spun simultaneously, every side on each of the spinner carries equal probability of landing. In order for there to be only 10 possible outcomes, no more no less, the spinners cannot be identical. One of the spinner in two sided while the other spinner must then be a five sided spinner. Choosing this particular pair of spinners gives Nathan 10 possibilities of combinations.

The table shows the amount spent on tomatoes at three different stands at a farmer's market. Which stand sold their tomatoes at the least expensive price per pound, and what is that price? Round to the nearest cent as necessary.​

Answers

Answer:

i have the same question someone pls answer

Step-by-step explanation:

Stand C sold their tomatoes at the least expensive price per pound that price is 2.70 per pound.

What is Ratio?

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

Stand    Weight(lb)    Cost

  A            3/4             2.00

  B            1 1/4            3.45

  C            5 1/2            14.85

We have to determine the price of sold tomatoes at the least expensive price per pound.

the price of sold tomatoes at stand A:

⇒ 2/(3/4) = 2/0.75  = 2.67 per pound.

the price of sold tomatoes at stand B:

⇒ 3.45/(5/4) = 3.45/1.25  = 2.76 per pound.

the price of sold tomatoes at stand C:

⇒ 14.85/(11/2) = 14.85/5.5= 2.70 per pound.

Here is the least expensive price per pound at stand C.

Therefore, stand C sold their tomatoes at the least expensive price per pound that price is 2.70 per pound.
