find an equivalent expression to 3 (4m-2)-2(m+5). write your answer as an expression with two terms

Answer:10 sec

Step-by-step explanation:

Given

Boris can run up the escalator in 6 sec

Also he can run up the down escalator in 30 sec

i.e. He travel same distance either ways

Let the distance be x and v be the speed of boris and [tex]v_0[/tex] be the speed of escalator.

[tex]x=6\times \left ( v+v_0\right )[/tex]----1

[tex]x=30\times\left ( v-v_0\right )[/tex]----2

Equating 1 and 2

[tex]5\left ( v-v_0\right )=v+v_0[/tex]

[tex]5v-5v_0=v+v_0[/tex]

[tex]v_0=\frac{2}{3}v[/tex]

substituting in 1

[tex]x=6\times \left ( v+v\frac{2}{3}\right )[/tex]

[tex]x=6\times v\frac{5}{3}=10v[/tex]

Thus form above equation we can say that it requires 10 sec for Boris to climb up in out of service escalator.

Answer:

7 and 1 over 3 multiplied by 1 over 6

Step-by-step explanation:

Answer:

The correct answer is A.

This is because the whole number 28 has a 2 in the tens place, meaning it has 2 tens, and 10x2=20. Same goes for the 8 in the ones place (8x1=8)

20+8=28. Then, 19/100 is equal to 0.19, which has a 1 in the tenths place and a 9 in the hundreths place put together to get 28.19

Answer = 1/6

Step-by-step explanation:

3 ft are in 1 yard

so 3/18

= 1/6

As per linear equation, 3 feet to 6 yard in simplest form is [tex]\frac{1}{6}[/tex].

A linear equation is an equation where there are one or multiple variables. However, the highest power of any variable is one.

We know, [tex]3 feet = 1 yard[/tex]

Therefore, 3 feet to 6 yard in simplest form is

[tex]= \frac{3 feet}{6 yard}\\ = \frac{1 yard}{6 yard} \\= \frac{1}{6}[/tex]

The ratio 6/11 does not represent all of Stephen's purchases, as it excludes the $4 he spent on milk.

A ratio is a mathematical relationship that demonstrates how frequently one number contains or is contained inside another. Two numbers are compared using it.

If Stephen had written the ratio of the total amount spent on eggs and cereal to the amount spent on milk, it would have been:

(6 + 11) / 4 = 17/4

This ratio is also a fraction, but it cannot be simplified to a whole number, as the numerator and denominator have no common factors other than 1.

Therefore, the ratio 6/11 is a fraction that represents a comparison between two of Stephen's purchases, but it does not represent all of his purchases, and it is not the only possible ratio that can be written using the given information.

The bakery uses 54 cups of flour to make a full cart of bread.

Given that, a bakery uses 3 cups of flour to make each loaf of bread. There are 3 loaves of bread on a tray.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Now,

6 trays x 3 loaves per tray= 18 loaves

18 loaves x 3 cups of flour each= 54 cups of flour

Therefore, the bakery uses 54 cups of flour to make a full cart of bread.

Final answer:

Solving the equation 1/3(2x-4)+5=-2/3(x+1) involves distributing the fractions, combining like terms, and then multiplying by the reciprocal to isolate x, which results in a solution of x = -4.

Explanation:

To solve the linear equation 1/3(2x-4)+5=-2/3(x+1), you start by distributing the fractions across the parentheses and then combine them like terms. First, multiply 1/3 by each term inside the parentheses (2x-4) and -2/3 by each term inside (x+1), which gives:

2/3x - 4/3 + 5 = -2/3x - 2/3

Next, combine like terms and add 2/3x to both sides:

2/3x + 2/3x = -2/3 - 5 + 4/3

This simplifies to:

4/3x = -16/3

To isolate x, multiply both sides of the equation by the reciprocal of 4/3, which is 3/4:

x = (3/4) x (-16/3) = -4

The solution for x in the given equation is -4.

Final answer:

To solve the equation 1/3(2x-4)+5=-2/3(x+1), we need to simplify the equation and isolate the variable x. The solution to the equation is x = -7/12.

Explanation:

To solve the equation 1/3(2x-4)+5=-2/3(x+1), we need to simplify the equation and isolate the variable x. Let's start by distributing and solving the equation:

1/3(2x-4)+5=-2/3(x+1)

(2/3)x - 4/3 + 5 = (-2/3)x - 2/3

Combining like terms:

(2/3)x + 5/3 = (-2/3)x - 2/3

Add (2/3)x to both sides:

(2/3)x + (2/3)x + 5/3 = (-2/3)x + (2/3)x - 2/3

Simplify:

(4/3)x + 5/3 = -2/3

Subtract 5/3 from both sides:

(4/3)x + 5/3 - 5/3 = -2/3 - 5/3

Simplify:

(4/3)x = -7/3

Finally, divide both sides by 4/3 to solve for x:

(4/3)x / (4/3) = -7/3 / (4/3)

Simplify:

x = -7/12

Therefore, x = -7/12 is the solution to the equation.

Answer: 2/5

Step-by-step explanation: Using the place value chart, we can see that the decimal 0.4 is four tenths, so we can write 0.4 as the fraction 4/10.

Notice however that 4/10 is not in lowest terms so we need to divide the numerator and the denominator by the greatest common factor of 4 and 10 which is 2.

So if we divide the numerator and the denominator by 2, we get the equivalent fraction 2/5.

Therefore, 0.4 can be written as the fraction 2/5 which is in lowest terms.
