5/3 X + 10/7 = 30/7

¿como se resolveria?

Answer:44

Step-by-step explanation:

Just you the proportions:

so you will get (20*33)/15 which is equals to 44

Answer:

44

Step-by-step explanation:

From the one side the relationship is 15:20, so for this side it's 33:??

15/20 = .75

33/.75 = 44

Answer:

It is not correct, x = -5

Step-by-step explanation:

Answer:

no

Step-by-step explanation:

because 5+15=10

-15=15

x= -5

which means its NOT a solution because it equals -5

Answer:

C) $130

Step-by-step explanation:

simplify the equation:

p = 210 - (20 * 4)

p = 210 - (80)

p = 130

Answer:

See the answers below

Step-by-step explanation:

Given data

Length = 1/5mile

Width= 3/8 mile

The expression for the perimeter

P=2L+2W

Substitute

P=2*1/5+ 2* 3/8

P= 2/5+6/8

P= 16+30/40

P=46/40

P= 23/40 miles

Area= Length *Width

Area= 1/5* 3/8

Area= 3/40 square miles

Answer:

(y-3) = 2(x-1)

Step-by-step explanation:

Point slope form is

(y-y1) = m(x-x1)  where m is the slope and (x1,y1) is a point on the line

(y-3) = 2(x-1)

Answer:

c=9.20p

Step-by-step explanation:

cost is what you're solving for so that goes on the outside. each package costs 9.20 so you multiply however many packages by that number when finding the cost.

Stepby-step explanation:

Answer:

60 books were at the book sale

Step-by-step explanation:

Let

x = total books at the book sale

Percentage of books sold = 80% of x

= 80/100 * x

= 0.8x

Number of books sold = 48

Therefore,

0.8x = 48

Divide both sides by 0.8

0.8x / 0.8 = 48 / 0.8

x = 60 books

x = total books at the book sale = 60 books

Number of books unsold = Total books at the book sale - number of books sold

= 60 - 48

= 12

Number of books unsold = 12 books

Answer: 72.32

Step-by-step explanation:

The line is 180 so

7x + 8x + 44.4 = 180

15x + 44.4 = 180

-44.4         =  -44.4

15x = 135.6

divide both by 15

x = 9.04

So 8 * 9.04 = 72.32

Answer:

The answer is 72.32°

Step-by-step explanation:

So, since that is a straight line, we know that all of the angles add up to get 180° total. Using this knowledge, we can determine that 44.4 + 8x + 7x = 180°.

First, we need to find what x is to find the missing values. To do that, we have to set all the values, 44.4, 8x, and 7x equal to 180, because we know they add up to 180°.

44.4 + 8x + 7x = 180

Combine the like terms.

44.4 + 15x = 180

Bring the 44.4 over to the other side in order to get x alone by subtracting it from 180.

15x = 135.6

Divide both sides by 15 to get x completely alone.

x = 9.07

Now we have what x is, 9.07.

All you need to do now is substitute 9.07 into the place of x.

8(9.07) = 72.32

So now you know that the highlighted angle is 72.32°.

Answer:

hello your question is incomplete attached below is the complete question

answer : 36080

Step-by-step explanation:

Finished good inventory = 24% of next month estimated sales

Determine the budget level of production for September

For September

Initial unit on table = 38,000

Beginning inventory = 24% of 38000 = 9120

ending inventory = 24% of 30,000 = 7200

∴ Budget level of production = 38000 - 9120 + 7200 = 36080 units

Answer:

its neither

Step-by-step explanation:

supplementary means the angles would equal 180° and complementary means the Angel's would equal 90°

in this case the angles equal to neither.

Answer:

1.neither

as there sum =56+142=198°

3.supplementary

sum =57+123=180°

Answer:

[tex](x,y) = (2,1)[/tex]

Step-by-step explanation:

Given

Coordinate: (-3,-9) and (4,5)

Ratio= 5 : 2

Required

Determine the point at the segment

The coordinate of the point is calculated using:

[tex](x,y) = [\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n}][/tex]

Where:

[tex]m : n=5:2[/tex]

[tex](x_1,y_1) = (-3,-9)[/tex]

[tex](x_2,y_2) = (4,5)[/tex]

So, we have:

[tex](x,y) = [\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n}][/tex]

[tex](x,y) = [\frac{5 * 4 + 2 * -3}{5+2},\frac{5*5+2*-9}{5+2}][/tex]

[tex](x,y) = [\frac{14}{7},\frac{7}{7}][/tex]

[tex](x,y) = (2,1)[/tex]

The coordinate of the point is: (2,1)

Answer:

y = 6x

Step-by-step explanation:

Equation representing the relation between duration of work and earning is,

y = kx

Here, y = earnings

x = Working hours

k = Proportionality constant

By substituting the values in the given equation,

x = 25 hours

y = $150

150 = k(25)

k = 6

Therefore, equation modeling the situation will be,

y = 6x

Answer:

y=-6/5x-2

Step-by-step explanation:

We are given points (5,-8) and (-5,4)

Slope = m = (y₂-y₁)/(x₂-x₁) = (-8-4/(5-(-5)) = -12/10 = -6/5

Y-intercept = b = (0,-2)

Final equation: y=-6/5x-2

Answer:

y=-6/5x-2

Step-by-step explanation:

y=mx+b

Its sloping downwards, so a negative slope.

two points: (-5,4) and (5,-8)

---------------------------------------------

so first find the slope.

y2-y1 / x2-x1  <= formula

so: -8-(4) / 5-(-5)

which becomes => -12/ 10

which is 6/5 the slope is 6/5

------------------------------------------

plug this into y=mx+b, where m is the slope

so: y=6/5x+b

------------------------------------------

obviously b is the y intercept, where the line meets y

the y intercept is -2

sooooooo final answer is

----------------------------------

y=6.5x+(-2)

-----------------------------------

Negative slope, so becomes y=6/5x-2

Answer:

4,498,252,900 km

Step-by-step explanation:

Answer:

8 hours

Step-by-step explanation:

Given data

Commission= 5%

Sales= $3,200

Total earnings= $240

Let us find the amount in commission earned

=5/100*3,200

=0.05*3,200

=$160

Hence 240-160=$80

$80 is the amount earned yesterday

we are told that per hour is $10

Hence $80 will be earned for

=80/10

=8 hours

Answer:

Step-by-step explanation:
