Simplify the expression

Answer:

m=8

hope this helps

have a good day :)

Step-by-step explanation:

2 + 6m +7=57

9+6m=57 add like terms

6m=48 subtract 9 from each side

m=8 divide by 6 on each side

Answer:

M=8

Step-by-step explanation:

First your going to subtract 2 from 7 and thats 5.

then your going to do:

6m+5=57

Then subtract 5 from 57 and thats 52

and divide 52 from 6 and thats 8.

Answer:

Infinite many solutions

Step-by-step explanation:

If you graph it there is only 1 line

Answer

It is the first answer.

Step-by-step explanation:

Parallel lines are lines that will never cross each other.

Perpendicular lines are lines that cross each other at 90 degree angles (represented by the box in the corner).

A set of parallel lines and a set of perpendicular lines in this image are; AB║CD, CD ⊥ EF and AB ⊥ EF

Parallel lines have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope.

Since Parallel lines are lines that will never cross each other.

We know that Perpendicular lines are lines that cross each other at 90 degree angles.

The parallel lines are AB and CD, the perpendicular are AB and EF because the first sets are side by side and the second sets cross each other at a certain point.

Therefore the  set of parallel lines and a set of perpendicular lines in this image are; AB║CD, CD ⊥ EF and AB ⊥ EF

Step-by-step explanation:

the equation would be y= 40x + 20 since 20 is the starting price and everyday you add 40 dollars. put in what day it is as X to get the answer

Answer:

y = [tex]-\frac{1}{5}x[/tex] - 4

Step-by-step explanation:

As we know the point slope form of an equation is as follows -

y - y₁ = m ( x - x₁ )

As we have slope , m = [tex]-\frac{1}{5}[/tex]

And point (x₁ , y₁ ) = ( -5, -3)

⇒ y - ( -3) = [tex]-\frac{1}{5}[/tex] ( x - (-5) )

⇒ y + 3 = [tex]-\frac{1}{5}[/tex] ( x + 5 )

⇒ y + 3 = [tex]-\frac{1}{5}[/tex] x - 1

⇒ y =  [tex]-\frac{1}{5}[/tex] x - 1 - 3

⇒ y =  [tex]-\frac{1}{5}[/tex] x - 4

So, the equation becomes

y = [tex]-\frac{1}{5}x[/tex] - 4

hegarty maths man told me so.

The value of x is 3.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

As, we know that The median (also called a midline or midsegment) is a line segment half-way between the two bases.

median = (a+ b ) / 2

So, 12.5 = (3x+1 + 15) / 2

12.5 = 3x + 16 / 2

25 = 3x + 16

3x = 9

x= 3

Hence, the value of x is 3.

Answer:

44

Step-by-step explanation:

1. Find out how many coins were foreign

x.           84

------ = ---------

275.      100

2. Subtract 231 (Foreign coins) by 275 (Total coins)

3. The answer is 44

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

The number of foreign coins.

84% of 275 = 231

The number of foreign coins is 231.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Total number of coins = 275

Percentage of foreign coins = 84%

The number of foreign coins.

= 84% of 275

= 84/100 x 275

= 231

Thus,

The number of foreign coins is 231.

Answer:

30

Step-by-step explanation:

90+2x+x=180

3x=90

x=30

Answer:

30

Step-by-step explanation:

First we can find the total angle that we are "adding" to. This total angle is 180 degrees. Now since there is a right angle, H,E,G, we can remove 90 from that total to get 90. Now for x. Since there is a total of 3 x's, we divide 90 by 3 to get 30.

Given:

The expression  is

[tex]-3\sqrt{50a^2b^2}[/tex]

To find:

The simplified form of the given expression.

Solution:

We have,

[tex]-3\sqrt{50a^2b^2}[/tex]

It can be written as

[tex]=-3\sqrt{2\times 25a^2b^2}[/tex]

[tex]=-3\sqrt{2\times 5^2a^2b^2}[/tex]

Using the properties of radical and logarithm, we get

[tex]=-3\sqrt{2\times (5ab)^2}[/tex]        [tex][\because (mn)^x=m^xn^x][/tex]

[tex]=-3\sqrt{2}\times \sqrt{(5ab)^2}[/tex]               [tex][\because \sqrt{mn}=\sqrt{m}\sqrt{n}][/tex]

[tex]=-3\sqrt{2}\times 5ab[/tex]

[tex]=-15\sqrt{2}ab[/tex]

Therefore the simplified form of the given expression is [tex]-15\sqrt{2}ab[/tex].

Answer:

5 servings

Step-by-step explanation:

Given that:

For a particular first snack  to be = 270 calories;

the servings = 3

Then, for the second snack, the calories = 450.

To estimate the servings for the second snack; we need to equate the first snack with the second snack.

Let y be the value of the unknown second snack

Then:

270 calories = 3 servings

450 calories = y servings

y servings = (450 calories × 3 servings) / 270 calories

y servings = 5 servings

Thus; the second snack needs to have 5 servings in order to be equivalent to the first snack

Answer:

4

Step-by-step explanation:

1.25(4x-10)=7.5

First step is to divide the 1.25 on both sides

4x-10 = 6

next step is to get x by itself by adding 10 to both sides

4x = 16

continue getting x by itself by dividing both sides by 4

x = 4.

Answer:

174 cheeseburgers

Step-by-step explanation:

The computation of the number of 3 by 4 pound cheese burgers made is shown below:

3 by 4 would be written as 0.75 pound

And, 130 2 ÷ 3 = 130.66667 pounds

Now the number of 3 by 4 pound cheese burgers made is

= 130.66667 pounds ÷ 0.75 pound

= 174.22

= 174 cheeseburgers
