Answer:

x=-12.8 or −64 /5

Step-by-step explanation:

ok easy as pie

interior plus exterior is 180 degrees

so 180-130=50

we know the last angle = 50

now lets add them all up and they should be equal to 180

all traingles interior angles add up to 180

180=(-21x+1)+(11x+1)+(50)

now solve

180=-21x+1+11x+1+50

180=-10x+52

52-10x=180

subtract 52

-10x=128

-12.8=x

x=-12.8 or −64 /5

Answer:

The cost of one hosta is $6

Step-by-step explanation:

A system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.

Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied.

In this case, the variables are:

If Kim spent $62 on 5 hostas and 4 pots of ivy, t his is represented by the equation: 5*x +4*y= 62

If Danielle spent $144 on 8 hostas and 12 pots of ivy, t his is represented by the equation: 8*x +12*y=144

So, the system of equations to solve is:

[tex]\left \{ {{5*x+4*y=62} \atop {8*x+12*y=144}} \right.[/tex]

One way to solve a system of equations is through the substitution method, which consists of solving or isolating one of the unknowns (for example, x) and substituting its expression in the other equation. In this way, you obtain an equation of the first degree with the other unknown, and. Once solved, you calculate the value of x by substituting the already known value of y.

Isolating y from the first equation:

[tex]y=\frac{62-5*x}{4}[/tex]

and replacing this expression in the second equation you get:

[tex]8*x +12*\frac{62-5*x}{4}=144[/tex]

Solving:

[tex]8*x +\frac{12}{4}*(62-5*x)=144[/tex]

8*x + 3*(62-5*x)=144

8*x + 3*62 - 3*5*x=144

8*x + 186 - 15*x=144

8*x  - 15*x=144 -186

(-7)*x= -42

x= (-42)÷ (-7)

x= 6

The cost of one hosta is $6

Answer:

Step-by-step explanation:

Answer:

y=447.3 pounds

x= 297.3 pounds

Step-by-step explanation:

Step one:

given data

Tea A costs $9 per pound and

Tea B cost $6 per pound.

let the number of pounds of Tea A be x

and for Tea B be y pounds

The total cost of the mixture = $8 per pound

hence

9x+6y=8---------1

The total weight of the mixture

150 pounds

x+y=150-----------2

Step two:

9x+6y=8---------1

x+y=150---------2

from eqn 2 x=150-y

put x= 150-y in eqn 1

9(150-y)+6y=8---------1

1350-9y+6y=8

1350-8=9y-6y

1342=3y

divide both sides by 3

y= 1342/3

y=447.3 pounds

put y= 447.3 in eqn 2

x+447.3= 150

x= 150-446=7.3

x= -297.3

x= 297.3 pounds

Answer:

450

Step-by-step explanation:

Length = l

Breadth = b

l = 15 + b

Perimeter = 90

Perimeter = 2(l + b)

90 = 2(15 + b + b)

90 = 2(15 + 2b)

90 = 30 + 4b

90 - 30 = 4b

60 = 4b

60/4 = b

15 = b

Hence, l = 15 + 15 = 30

Area = l * b

Area = 30 * 15

Area = 450 unit²

Step-by-step explanation:

Answer:

4/5 + 3/4 = [tex]1\frac{11}{20}[/tex] or 1.55

Step-by-step explanation:

This can be solved by first finding the highest common factors of denominators of the two fractions, i.e. 4 and 5.

The highest common factor of 4 and 5 can be found by multiplying the two numbers as follows:

The highest common factor of 4 and 5 = 4 * 5 = 20

This can now be used to solve  4/5 + 3/4 as follows:

4/5 + 3/4 = ((4 * 4) + (5 * 3)) / 20 = (16 + 15) / 20 = 31 / 20 = [tex]1\frac{11}{20}[/tex] or 1.55

Therefore, we have:

4/5 + 3/4 = [tex]1\frac{11}{20}[/tex] or 1.55

Answer:

Yes, he is correct

Step-by-step explanation:

Represent Michael's home with M and his mother's with H

So, we have:

[tex]M = 12\ ft (below)[/tex]

[tex]H = 12\ ft (above)[/tex]

Required

Is Michael correct?

First, we get the numeric values of the given parameters.

Below sea level means negative:

So:

[tex]M = 12\ ft (below)[/tex] will be rewritten as:

[tex]M = -12[/tex]

Above sea level means positive:

So:

[tex]H = 12\ ft (above)[/tex] will be rewritten as:

[tex]H = 12[/tex]

Two numbers [tex]A\ and\ B[/tex] are said to be opposite if [tex]A + B=0[/tex]

For Michael to be correct:

[tex]M + H = 0[/tex]

Substitute values for M and H

[tex]-12 + 12 = 0[/tex]

[tex]0 = 0[/tex]

Hence, Michael is correct

Answer:

B

Step-by-step explanation:

Here, we want to find the point-slope equation of the line

We start by getting the y-intercept of the line which is y = 3

The general equation of a straight line is;

y = mx + b

where b is the y-intercept

So, we have;

y = mx + 3

Now, to get m , we insert the point given on the like which is (2,-5)

x = 2 and y = -5

-5 = 2m + 3

-8 = 2m

m = -8/2

m = -4

So the equation of the line is;

y = -4x + 3

This is same as option B

Answer:

C

Step-by-step explanation:

When you subtract the actual number from the estimated number then, its called 'Error''.

Option B is true.

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

You subtract the actual number from the estimated number.

Now,

We know that;

To find the error , we subtract the actual number from the estimated number.

Hence, We get;

After subtract the actual number from the estimated number, the result is called ''Error''.
