<span>5 1/4 + x + 6 5/6 + 4 2/3 = 22 1/6

5 3/12 + x + 6 10/12 + 4 8/12 = 22 2/12
15 21/12 + x = 22 2/13
</span>16 9/12<span> + x = 22 2/12
x = 22 2/12 - </span>16 9/12<span>
x = </span>21 14/12 - 16 9/12
x = 5 5/12

answer is <span>A. 5 5/12</span>

V-16=-32<br>I need help with the math worksheet how to solve the question
sergeinik [125]

You solve an equation like this by adding the opposite of the constant to both sides of the equation.

... V -16 +16 = -32 +16 . . . . . addition property of equality: if a=c, then a+b = c+b

... V + 0 = -16 . . . . . . . . . . . . additive inverse property of integers: -16+16 = 0

... V = -16 . . . . . . . . . . . . . . . identity element of addition: V+0 = V

_____

<em>You can always do the same thing to both sides of an equation.</em> Here, it is useful to add the opposite of -16 to both sides. That way the constant on the left becomes zero, so you only have the variable by itself—which is what you want.

Units of Capacity
marysya [2.9K]

Answer:

            \large\boxed{\large\boxed{0.2deciliter}}

Explanation:

Build your conversion factors using the conversion table:

  • 1 cup = 0.237 liters\implies 1=0.237liters/1cup

From the prefixes used in the metric system, you know that 1 deciliter = 0.100 liters. Then:

  • 1 deciliter = 0.100 liters\implies 1=1deciliter/0.100liters

Arrange the expression to simplify the units and convert from cups to deciliters:

  • 9cups\times 0.237liters/cup\times 1deciliter/0.100liters=0.2133deciliter

Round to the nearest tenth: 0.2 deciliter.

PLEASE PLEASE HELP
noname [10]

Answer:

8.51x10^{-3}cm

Step-by-step explanation:

In order to add or subtract numbers in scientific notation, the powers of ten must have the same exponent.  In this caes the diameter of an average human body cell is a power of -4 and the diameter of a plant cell is a power of -3.  In order to add them, we can move the decimal over for the body cell diameter:

5.1x10^{-4}=0.51x10^{-3}

Add the two values: 0.51x10^{-3}+8x10^{-3}=8.51x10^{-3}cm

Find the product of the monomial and the polynomial. 4a^2b^3*(9a^4b^2-4a^2+3)
Artemon [7]

Answer:

Step-by-step explanation:

4a² b³ * (9a⁴b² - 4a² + 3) = 4a²b³ * 9a⁴b² - 4a²b³*4a² + 4a²b³*3

                                        = 36a²⁺⁴ b³⁺²  -16a²⁺²b³ + 12a²b³

                                         = 36a⁶b⁵ - 16a⁴b³ + 12a²b³
