Which of the following is another way to express the difference between -5 and 8

Answer:

Yes

Step-by-step explanation:

Is [tex]34.223[/tex] greater than [tex]34.232[/tex]?

Let's compare these two decimals.

[tex]34.223[/tex]  ?  [tex]34.232[/tex]

It may look like [tex]34.232[/tex] is bigger but it actually isn't. The first thing you have to do is look at the last digit in the decimal.

In the first decimal([tex]34.223[/tex]), the last digit is 3. In the second decimal([tex]34.232[/tex]), the last digit is 2. 3 is bigger than 2 so the decimal that is greater is [tex]34.223[/tex].

Hope this helps!

Answer:

Step-by-step explanation:

The same bases (9) needs the same exponents to be equal:

[tex]\big9^{2x + 1}=\big9^{3x-2}\quad\iff\quad 2x+1=3x-2\\\\2x+1=3x-2\\\\2x-3x=-2-1\\\\-x=-3\\\\x=3[/tex]

The computation of the indices show that the value of x in 9^(2x + 1) = 9^(3x – 2) is 3.

From the information given, we are told to simply solve 9^(2x + 1) = 9^(3x – 2). In this case, the exponents given are equal which is 9.

Therefore, 2x + 1 = 3x - 2

Collect like terms

3x - 2x = 1 + 2

x = 3

Therefore, the value of x is 3.

Answer:

[tex] {b}^{2} + 5b - 14[/tex]

Step-by-step explanation:

By algebraic identity:

[tex](x + a)(x + b) = {x}^{2} + (a + b)x + ab \\ we \: have \\ (b - 2)(b + 7) \\ = {b}^{2} + ( - 2 + 7)b + ( - 2)7 \\ = {b}^{2} + 5b - 14[/tex]

Answer:

Phyllis invested $11,000 at a simple interest rate of 7 percent per year and $40,000 at a simple interest rate of 4 percent per year.

Step-by-step explanation:

From the information provided, you can write the following equations:

x+y=51000 (1)

0.04x+0.07y=2370 (2), where

x is the portion earning a simple interest rate of 4 percent per year

y is the portion earning a simple interest rate of 7 percent per year

First, you can isolate x in (1):

x=51000-y (3)

Now, you can replace (3) in (2) and solve for y:

0.04(51000-y)+0.07y=2370

2040-0.04y+0.07y=2370

0.03y=330

y=330/0.03

y=11000

Then, you can replace the value of y in (3) to find the value of x:

x=51000-11000

x=40000

According to this, the answer is that Phyllis invested $11,000 at a simple interest rate of 7 percent per year and $40,000 at a simple interest rate of 4 percent per year.

Answer:

The answer is -13.

Step-by-step explanation:

We get the smallest value of [tex]x[/tex] when [tex]x+1[/tex] is the most negative factor of 12, which is -12. Therefore,

                                                     [tex]x+1=-12\\x=\boxed{-13}[/tex]

Step-by-step explanation:

Let the first side is x, second side is (x+1) and the third sie is (x+2). The perimeter of the triangle is 114 cm.

It means,

x+x+1+x+2=114

3x+3=114

3(x+1)=114

x+1=38

x=37

So, first side is 37 cm

Second side is 37+1=38 m

Third side is 37+2=39 m

Hence, this is the required solution.

Answer:

  7 1/2 days

Step-by-step explanation:

The carpenter can do 1/5 of the work in 1 day. The assistant, who takes 'a' days to do the work, can do 1/a of the work in 1 day. Together, they can do 1/3 of the work in 1 day:

  1/5 + 1/a = 1/3

  1/a = 1/3 -1/5 = 2/15

  a = 1/(2/15) = 15/2 = 7.5

The assistant takes 7.5 days to do the work alone.

Answer:

x^2 - 2x - 13x + 26 = (x-2)(x-13)

Step-by-step explanation:

x^2 - 15x + 26 = x^2 - 2x - 13x + 26 = (x^2 - 2x) - (13x - 26)

= x(x-2) - 13(x-2) = (x-2)(x-13)

s = 2d / t

Multiply both sides by t

st = 2d

Divide both sides by 2

st / 2 = d

Answer:

The number of ways the bus can be filled is 28 ways

Step-by-step explanation:

The given parameters are;

The number of seats in the bus =  6

The number of passengers available = 8

The number of ways the bus can be filled involve the number of ways of selecting from the 8 passengers taking 6 at a time given as follows;

The combination of n items, taking n items, taking r at a time is [tex]_nC_r[/tex]  which can be given as follows;

[tex]_nC_r = \dfrac{n!}{r! \cdot (n - 1)}[/tex]

Therefore;

The number of ways the bus can be filled is therefore;

[tex]_8C_6 = \dfrac{8!}{6! \times (8 - 6)!}= \dfrac{8!}{6! \times 2!} = \dfrac{8 \times 7}{2 \times1} = 28 \ ways[/tex].
