Answer:

Step-by-step explanation:

There are 120 members of the band at Erin's school. 45% of the members are 7th graders. How many members are 7th graders.

you simply have to find 45% of 120

120 : 100 * 45 = 54

Answer:

x=15

Step-by-step explanation:

Since 13+6+2x-18= 4x-29, use this equation.

Combine like terms:

1+2x= 4x-29

-1            -1

2x= 4x-30

-4x     -4x

[tex]\frac{-2x=-30}{-2}[/tex]

x=15

Answer:

90-56= 34

good luck!

Answer:

90-56=34

Step-by-step explanation:

90 degrees minus the given amount of the other degrees will give u the answer 90-56=34

Answer: Binomial

Monomial= 1 term

Binomial= 2 terms

Trinomial=3 terms

Polynomial= 4 terms or more

We want to see if the statement "The relationship among the triple constraint variables is such that if any one changes, at least one other is likely to be affected." is true or false. This is true.

A relationship among the triple constraint variables is written as:

y = f(x, z)

Where the 3 variables are x, y, and z and represent cost, scope, and time.

This means that if either x or z changes, also does y.

And we always can rewrite the relationship in two other forms:

x = g(z, y)

z = h(x, y)

Then we can see that always that one variable changes, at least one other variable changes in response, then the statement is true.

Step-by-step explanation:

the most usual firm of line equation is

y = ax + b

a is the slope of the line and is expressed as the ratio

y coordinate change / x coordinate change

when going from one point to the other.

b is the y-interception (the bake of y when x = 0).

once we have the slope, we get b by using the coordinates of one of the given points as x and y in the equation and solve for b.

the slope a :

x changes by +3 (from 3 to 6)

y changes by +8 (from -1 to 7)

so, the slope is +8/+3 = 8/3

our line equation now looks like

y = (8/3)x + b

let's simply use the first point

-1 = (8/3)×3 + b

-1 = 24/3 + b = 8 + b

-9 = b

and the full line equation is

y = (8/3)x - 9

Answer:

A. [tex]h(x)=f(x+1)[/tex]

Step-by-step explanation:

Let's start doing exactly what each function says.

[tex]g(x) = 3x+3[/tex]

At this point, let's see what the various h-s do. Let's call each [tex]h_A... h_D[/tex] to understand which flavor of it we're talking about.

[tex]h_A(x)=f(x+1) = 3(x+1)=3x+3 = g(x)\\h_B(x)=2f(x)=2\cdot3x= 6x \ne g(x)\\h_C(x)=f(x-1)=3(x-1)=3x-3\ne g(x)\\h_D(x)= f(x)+1= 3x+1\ne g(x)[/tex]

3 e^3

Divide the constants

We know that  dividing exponents with the same base means subtracting the exponents

e^5 / e^3 = e^(5-3) = e^2

Answer:

8 feet

Step-by-step explanation:

5 + 3 = 8

Answer:

Step-by-step explanation: The school of salmon are now 8 feet below the surface. They start at -5 feet and then you subtract 3 more feet which gives you -8 feet. -5-3=8

[tex]3x-25 =11x -5 +2x \\\\\implies 3x -25 = 13x-5\\\\\implies 13x -3x = 5-25\\\\\implies 10x = -20\\\\\implies x = -2[/tex]

Answer:

3x-10=x+15+25

3x-10=x+40

3x-x=40+10

2x=50

x=50/2

x=25

Answer:

pretty sure 60, 5 x 12

Step-by-step explanation:

just do 5 x 12 if there's 12 tiles and their measurement is 5 inches each

so the answer would be 8+9n≥80. The reason why is because he has $80 and he saved $8 and he earned $9 for each hour but we do not know how many hours so that is why it is n. and it says minimum so u might think that it might be ≤ but my sister says to think the opposite so the symbol will be ≥.

Hope this helps ^_^
