I the fifth grade at Lenape Elementary School there are 4/5 as many students who do not where glasses as those who do where glasses. If there are 60 students who do not where glasses, how many students are in the fifth grade?​

Answer:

Step 1 and step 2

Step-by-step explanation:

she has to subtract 30 not add 30.

2(3x+6)=3(x-10)

6x + 12 = 3x-30

6x +12 - 12 = 3x - 30 - 12

6x = 3x - 42

6x - 3x = 3x - 42 - 3x

3x = -42

3x/3 = -42/3

x = -14

Answer:

B

Step-by-step explanation:

Hey There!

So the first thing we're going to do is solve it and then compare it to Maya's steps to see where she made the mistake

2(3x+6)=3(x-10)

step 1 distribute the 2 to whats inside of the parenthesis (3x+6)

2*3x=6x

2*6=12

now we have

6x+12=3(x-10)

step 2 distribute 3 to what's inside of the parenthesis

3*x=3x

3*-10=-30

we're left with

6x+12=3x-30

step 3 add 30 to each side

12+30=42

now we have

6x+42=3x

step 4 subtract 6x from each side

3x-6x=-3x

now we have

-3x=42

step 5 divide each side by -3

42/-3=-14

so x = -14

now lets compare our steps to maya's

as we look at the steps we notice that she messes up on step 2

when distributing 3 to -10

she gets positive 30 but its supposed to be -30

so we can conclude that she mad a mistake from step 1 to step 2

therefore the second one is your answer

Answer:B 28 cm^2

Step-by-step explanation:

The area of the pentagon is 28 cm².

Option B is the correct answer.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Apothem a = 2.75 cm

Side length s= 4 cm

Now,

Area of Pentagon = (5/2) x s x a

So,

= 5/2 x 4 x 2.75

= 5 x 2 x 2.75

= 10 x 2.75

= 27.5 cm²

= 28 cm²

Thus,

The area of the pentagon is 27.5 cm².

Answer:

Option B, trade with an app that charges a flat brokerage

fee of $3 per trade.

Step-by-step explanation:

1) In option A, the broker charges 2% brokerage. This means that 2% of the money invested goes to the broker. Since Angelika wants to invest $6000, the amount of money to be charged by the broker = 2% of $6000 = 0.02 * $6000 = $120

2) Option B uses an app that charges a flat brokerage of $3 per trade. This means that for any transaction, the money to be charged would be $3. Since Angelika wants to invest $6000, the amount of money to be charged by the broker = $3

Answer:

the answer is: 8(x)= 4 -5

Step-by-step explanation:

The graph of parent function and translated function are given below. Therefore, the transformation is shifted down 5 units.

The given function is g(x)=x-5.

A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.

Here, parent function is g(x) = x

To find the transformation, compare the function to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis, and if there is a vertical stretch.

Shifted down: 5 units

The graph of parent function and translated function are given below. Therefore, the transformation is shifted down 5 units.

Answer:

Firstly Substitute y=2x-5 into 5x-4y=-10

This will be 5x-4(2x-5)=10 now solve for x

5x-8x+20=-10

-3x=-30

X=10

Now sub x as 10 into the second equation y=2x-5

Y=2(10)-5

Y=15

Your answer would be -2/5

Step-by-step explanation:

The value of the given expression is -2/5.

The given expression is [tex]\sqrt[3]{-\frac{8}{125} }[/tex].

In mathematics, the definition of cube root is written as Cube root is the number that needs to be multiplied three times to get the original number. Now, let us look at the cube root formula, where y is the cube root of x. ∛x = y.

Now, [tex]\sqrt[3]{-\frac{8}{125} }[/tex] can be written as [tex]\sqrt[3]{(-\frac{2}{5})^{3} }[/tex].

Here, cube and cube root will get cancelled.

We get -2/5
