Answer: 6 1/3

Step-by-step explanation:

4x-14 = -2x+24

4x = -2x+24 + 14  [Add 14 to both sides]

4x + 2x = 24 + 14  [Add 2x to both sides]

6x = 38                 {Combine like terms]

 x  = (19/3) or 6 1/3

Step-by-step explanation:

[tex]-abc-5ac-4ab-20\\-a(bc+5c+4b+20)\\-a*c(b+5)+4(b+5)\\-a*(b+5)(c+4)[/tex]

The factor of the given expression is -a(b+5)(c+4)

Factorization in maths is the process of breaking down a number or a mathematical object into smaller or simpler factors that can be multiplied together to get the original number or object

Given is an expression, –abc –5ac –4ab –20a, we need to factor it completely,

-abc -5ac-4ab-20

- a(bc +5c+4b+20)

- ac(b+5)+4(b+5)

- a(b+5) (c+4)

Hence, the factor of the given expression is -a(b+5)(c+4)

Answer:

Yes it is possible

Step-by-step explanation:

let a = 10.3, b =5.8 , c= 4.6

a+b= 16.1>4.6=c

b+c=5.8+4.6=10.3>10.3=a

c+a=4.6+10.3=14.7>5.8=b.

Answer: B. SAS or/and E. HL

Step-by-step explanation:

The two triangles both have a right angle of 90 degrees and two sides that are congruent so, SAS (side-angle-side). It can also be by HL since they both have a hypotenuse (the 2 lines) and one leg (the 1 line) that are congruent to each other.

Answer:

[tex]2.5y^{3}x[/tex]

Answer:

According to the question,

[tex]12x + 8x + 5x = 75[/tex]

_____________________

[tex]12x + 8x + 5x = 75[/tex]

[tex]25x = 75[/tex]

[tex]x = \frac{75}{25} [/tex]

[tex]x = 3[/tex]

Now,

[tex]12x = 36[/tex]

[tex]8x = 24[/tex]

[tex]3x = 15[/tex]

So,

75 in the ratio of 12 : 8 : 5 is

36, 24 and 15

Answer:

36 : 24 : 15

Step-by-step explanation:

sum the parts of the ratio, 12 + 8 + 5 = 25 parts

Divide the quantity by 25 to find the value of one part of the ratio

75 l ÷ 25 = 3 l , then

12 parts = 12 × 3 = 36 l

8 parts = 8 × 3 = 24 l

5 parts = 5 × 3 = 15 l

Answer:

Step-by-step explanation:

Recall that distance = (rate)(time).  Here the rate is 30 mph and the time 3.5 hr.  The distance traveled is proportional to the time passing by.  The graph of the distance function is a straight line with slope equal to the "rate" named above:

d(x) = (30 mph)x

Since x (elapsed time) can't be negative in this situation, we write the domain as 0 ≤ x ≤ 3.5 hr.

Answer:

Area = 2x³ + 5x² - 1

Step-by-step explanation:

Given the length of a rectangle, (2x + 1), and its width of (x² + 2x - 1):

The formula for solving the area of a rectangle is given by:

Area of a rectangle = Length × Width

In order to solve for the area of a rectangle, simply multiply the given length by the width.

length (L) = (2x + 1)

width (W) = (x² + 2x - 1)

A = L × W

A = (2x + 1)(x² + 2x - 1)

Distribute the binomial, (2x + 1), into the trinomial, (x² + 2x - 1):

A = 2x³ + 4x² - 2x + x² + 2x - 1

Combine like terms:

A = 2x³ + 5x² - 1

Therefore, the area of a rectangle is: 2x³ + 5x² - 1.

Answer:

10 sheets of paper are striped

Step-by-step explanation: Make a proportional relationship.

20% as a fraction is 20/100

Make 50 into a fraction using a variable. For example, x/50

Cross multiply 20 and 50. That equals 1000.

Then divide 1000 by 100 and that equals 10. So 10 sheets of paper are striped.

Answer:

p = 5

Step-by-step explanation:

Judging from (0,0) and (10,-20) as given in the chart, the function is y = -2x.

Substituting that for the second row, you would get the equation -10 = -2x.

Simplifying, you get x = 5, so the value of p is 5.

Answer:

5

Step-by-step explanation:

First find the slope

m = ( y2-y1)/(x2-x1)

m = (-20-0)/(10-0)

   = -20/10

  = -2

We know the slope and have two points, (0,0) and (p,-10)

-2 = ( -10-0)/(p-0)

-2 = -10/p

Multiply each side by p

-2p = -10

Divide each side by -2

p = -10/-2

p = 5
