What is 2x+3+8x=3x+9x+7

Mathematics
1 answer:
Reika [66]3 years ago
3 0

Answer:

x=-2

Step-by-step explanation:

Hey there!

In order to solve this equation, you need to combine like terms

The equation after combining the x terms and the contants will look like this

10x+3=12x+7

Now you have to take 10x away from both sides

3=2x+7

Now bring all the constants to the left side

3-7=2x

Simplify

-4=2x

divide 2 on both sides to get x by itself

x=-2

So, the answer is x=-2

Answer: 55 \frac{5}{9} feet² or 55.556 feet²

Step-by-step explanation:

      The scale means that for ever one in the scale drawing, it is 20 in the actual room. We will convert the dimensions using proportions.

  \frac{5}{x}=\frac{1}{20}

  100 = x

-> The length is 100 inches

  \frac{4}{x}=\frac{1}{20}

  80 = x

-> The width is 80 inches

    The area of a rectangle can be found by multiplying the length by the width:

A = L * W

A = 100 * 80

A = 8,000 inches²

  To get this into square feet, we will divide by 144. Why? There are 12 inches in a foot. 12 times 12 is 144.

8,000 inches² / 144 = 55 \frac{5}{9} feet²

            The area of the room, in square feet, is 55 \frac{5}{9} feet².

Doreen is flipping two fair coins. What is the probability that both coins land on heads?
andrezito [222]

Answer:

There are four different possible outcomes: both coins are heads, the red coin is heads and the blue coin is tails, the red coin is tails and the blue coin is heads, or both coins are tails. Each outcome has equal probability. So the probability of both being heads is 1/4.

Identify a transformation of the function f(x) = x^2 by observing the equation of the function g(x) = (x - 6)^2.
Thepotemich [5.8K]
The correct answer is the third option:

The base graph has shifted 6 units to the right.

It is a horizontal translation, because it involves the subtraction of “h” from inputs (x values) causing it to shift to the right,

What is a simplified form of the expression (5^2)-^2Divided by 5^3
laila [671]

Answer:

5^ -7  =1 / 5^7

Step-by-step explanation:

(5^2)-^2/ 5^3

We know that a^b^c = a^(b*c)

(5^2)-^2 = 5^(2*-2) = 5^-4

5^-4/  5^3

We know that a^b /a^c = a^ (b-c)

5 ^ (-4-3)

5^ -7

If we don't want to use negative exponents

We know that a^ -b = 1/ a^b

1 / 5^7

Haley has 48 colored pencils and 3 cups (A, B, C). Cup A holds one more colored pencil than cup C. Cup B holds 2 more colored pe
Marina86 [1]

Answer:

17 pencils

Step-by-step explanation:

Assume that cup C holds x pencils. In this case, cup A holds x + 1 pencils, and cup B holds x + 2 pencils. We know that all of the cups together hold 48 pencils. If we add what we got together, we would get x + x + 1 + x + 2 = 48. 2x + 1 + x + 2 = 48. 2x + x + 1 + 2 = 48. 3x + 1 + 2 = 48. 3x + 3 = 48. 3x = 48 - 3. 3x = 45. x = 45 / 3. x = 15. Now, we know that cup C holds 15 pencils, and from here, we can find the number of pencils in cup B by adding 2 to 15 and getting 17, and that would be your answer.

Tell me if I'm wrong :)
