Answer:

Value of 8x -5y + 7 is 4.

Step-by-step explanation:

Given that:

8x-5y = -3     Eqn 1

It is a true equation.

Now we have to find the value of the given expression

8x -5y + 7

Putting value of 8x-5y from Eqn 1 in the given expression

8x - 5y + 7

-3 + 7

4

Therefore,

8x - 5y + 7 = 4

Hence,

Value of 8x -5y + 7 is 4.

1.Factor our the 2 from the equation

2.Your answer after will be 2(x+5)

Answer:

Step-by-step explanation:

Answer:

A proportional relationship is something like:

y = k*x

where k is the constant of proportionality.

Notice that in these relationships we will always have the pair (0, 0)

because if x = 0:

y = k*0 = 0

Then we always have x= 0, y = 0.

Notice that in the first two tables we have the points:

(2, 0) in the first one

(0, 1) in the second one.

then neither of these can be a proportional relationship.

The only option left is the third one.

To graph the relationship, we can just graph the four points in the table.

Then draw a line that passes through all the points, like in the image below.

And this line is written as:

y = 3*x

such that:

y(1) = 3*1 = 3 -----> (1, 3)

y(2) = 3*2 = 6 -----> (2, 6)

y(3) = 3*3 = 9 ------>  (3, 9)

Answer:

14x-2y

Step-by-step explanation:

just break down the expression by combining like terms and getting rid of the parenthesis like so:

2(x+y)+4(x+y)+8(x-y)

i multiplied the number in front of each parenthesis with both numbers inside

ex: 2(x+y)

2x+2y

result:

2x+2y+4x+4y+8x-8y

next:

14x-2y

Answer:

14x -2y

Step-by-step explanation:

2( x + y ) + 4( x + y ) + 8( x - y )

First, do the distributive property ( multiply what is in the parenthesis by what is out of it)

2( x + y ) + 4( x + y ) + 8( x - y )

2 * x + 2 * y + 4( x + y ) + 8( x - y )

2x + 2y + 4( x + y ) + 8( x - y )

2x + 2y + 4 * x + 4 * y + 8( x - y )

2x + 2y + 4x + 4y + 8( x - y )

2x + 2y + 4x + 4y +  8 * x + 8 * -y

2x + 2y + 4x + 4y + 8x - 8y

Now combine like terms

14x -2y

And you cannot simplify it anymore

Answer:

I'm pretty sure it's y= 45+25x

Answer:

y=45 + 25x

Step-by-step explanation:

When a question is asking for an initial fee, they are basically saying that you must pay that flat amount in addition to the amount you would pay for x hours of work. Say you work 5 hours. You have to multiply the number of hours, or x, by 25, then add 45.

Answer:

F = 12.14 m

Step-by-step explanation:

F is the side opposite the given 36° angle and the given side length, 15m is adjacent. It's a cosine equation that's needed.

find the cosine of 36°

(calculator necessary)

cos(36) = 0.8090169944

We should be safe to round that to .809 for this.

cos = opp/adj

Substitute what we know:

.809 = F/15 Multiply both sides by 15

.809(15) = F

12.135 = F Round to two places.

Side F is 12.14m

Answer:

the bat cost 1 dollar so subtract 1 dollar from 1.10 and you are left with .10 or 10 cents

Answer:

the ball costs $0.05

Step-by-step explanation:

if the total is $1.10, and the bat is $1 more than the ball, you do

1+2x=1.10. do the algebra, and you get 0.05. hope this helps.

Answer:

Mean score of 90 students = 77.2

Step-by-step explanation:

Mean score of 50 students from school A = 75

Mean score of 40 students from school B = 80

We need to find mean score of the 90 students?

First we will find sum of scores of students from school A

We know that: [tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}[/tex]

We have Average = 75, Number of terms = 50, We need to find Sum of terms (scores)

[tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}\\75=\frac{Sum\:of\:Terms}{50}\\Sum\:of\:Terms= 75\times 50\\Sum\:of\:Terms=3750[/tex]

So, Sum of scores for School A = 3750

Now, we will find sum of scores of students from school B

We know that: [tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}[/tex]

We have Average = 80, Number of terms = 40, We need to find Sum of terms (scores)

[tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}\\80=\frac{Sum\:of\:Terms}{40}\\Sum\:of\:Terms= 80\times 40\\Sum\:of\:Terms=3200[/tex]

So, Sum of scores for School B = 3200

Now, We will find mean score of the 90 students?

Mean score of 90 students will be:

[tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}\\Average=\frac{3750+3200}{90}\\Average=\frac{6950}{90}\\Average = 77.2[/tex]

So, mean score of 90 students = 77.2

Josh wants to add a model of a tree to his model railroad layout. How big should the model tree be if the actual tree is 315 inches and the scale is 1:90?

Answer:

4.5 inches

Step-by-step explanation:

The scale factor is 1:20 which is 1/20, and the actual height is 90 inches.

First, write down the proportion:

1/20 = x/90

Multiply both sides by 90.

=> x = 90/20

=> x = 4.5in

Therefore, the height of the model is 4.5 inches.
