Martin has 5/6 of a pizza Liam has four times as much pizza is Martin how much pizza does Liam have? (Put it in a fraction)

djverab [1.8K]

Answer:

The pizza of martin is $\dfrac{4}{5}$

Step-by-step explanation:

Given that,

Martin has $\dfrac{5}{6}$ of pizza.

Liam has four time much pizza.

Let us consider pizza is x.

We need to calculate the how much pizza of martin

Using given data

Pizza of Martin = $x\times\dfrac{5}{6}$

Pizza of Liam = $4\times(\dfrac{5}{6}x)$

The pizza of martin will be

$Pizza\ of\ martin=\dfrac{\dfrac{20}{6}x}{\dfrac{20}{6}x+\dfrac{5}{6}x}$

$Pizza\ of\ martin =\dfrac{4}{5}$

Hence, The pizza of martin is $\dfrac{4}{5}$

Rearrange the equation so U is the independent variable. 4u+8w=−3u+2w

Basile [38]

Answer:

$u=-\frac{6}{7} w$

Step-by-step explanation:

$4u+8w=-3u+2w$

Add $3u$ and $-8w$ on both sides.

$4u+3u=2w-8w$

Add or subtract like terms.

$7u=-6w$

Divide $7$ on both sides.

$7u/7=-6w/7$

$u=-\frac{6}{7} w$

$u$ is the independent variable now.

What is 2x times x squared?

tresset_1 [31]

We want to multiply the monomial $2x$ by the monomial $2x^2$ .

Remember that to multiply monomials we need to use the laws of exponents; in this case, the law for multiplying powers with the same base. The rule says that, when you multiply powers of the same base, you just need to add the exponents: $(a^m)(a^n)=a^{m+n}$ , $(x^2)(x^4)=x^{2+4}=x^6$ . Also, is worth pointing out that the exponent of a variable with no exponent is 1: $x=x^1$ .

Remember that we also need to multiply their coefficients , which are the numbers that multiply the variables; again, variables with no numbers have a coefficient of 1, so $x=1x$ . Multiply coefficients is easy, you just need to multiply them as you usually do with everyday numbers.
