Answer: A shirt costs $8 and the pants cost $ 12.

Step-by-step explanation:

Let x = Cost of each shirt, y = Cost of each pant.

As per given, we have

[tex]y-x=4 \ \ \ (i)\\\\ 10x-5y = 20\ \ \ (ii)[/tex]

Multiply 5 on both sides of (i), we get

[tex]5y-5x=20 \ \ \ (iii)[/tex]

Add (ii) and (iii), we get

[tex]5x=40\\\\\Rightarrow\ x=8[/tex]

From (i), y=4+8=12

Hence, a shirt costs $8 and the pants cost $ 12.

Answer:

1. B.

2. A, E.

3. D.

Step-by-step explanation:

1. 8.225 ÷ 5 = 1.645

2. 892 ÷ 8 = 111.5

8920 ÷ 80 = 111.5

894 ÷ 10 = 89.4

89.2 ÷ 0.08 = 1115

8.92 ÷ 0.8 = 11.15

0.892 ÷ 0.008 = 111.5

3. 4367 ÷ 0.004 = 1,091,750

Step-by-step explanation:

Answer:

7 in

Step-by-step explanation:

volume of a rectangular prism = width x height x length

width x length = area of the base

the sea shell box

200 = width x length x 5

width x length = 200/5 = 40cm^2

rock box

280 = 40in^2 x height

height = 280/40 = 7 in

Answer:

x=3.2

Step-by-step explanation:

2.5x=8

divide both sides by 2.5

x=3.2

Answer:

x = 3.2

Step-by-step explanation:

[tex]2.5x = 8[/tex]

[tex]2.5x - 2.5 = 8 \div 2.5[/tex]

[tex]x = 8 \div 2.5[/tex]

[tex]x = 3.2[/tex]

Answer:

125

Step-by-step explanation:

note that

625 = [tex]5^{4}[/tex]

Using the rule of exponents

[tex](a^{m}) ^{n}[/tex] ⇔ [tex]a^{mn}[/tex]

Then

[tex](5^{4}) ^{\frac{3}{4} }[/tex]

= 5³

= 125

Answer:

As a single power, we have the expression as (-24)^4

Step-by-step explanation:

Here, we want to write the expression into a single power

Using the indical laws, we have it that;

a^x/a^y = a^(x-y)

Thus, we have it that;

(-24)^5/-24 = (-24)^5-1 = -24^4

Answer:

[tex] x = \dfrac{2}{5} + \dfrac{\sqrt{14}}{5} [/tex]   or   [tex] x = \dfrac{2}{5} - \dfrac{\sqrt{14}}{5} [/tex]

Step-by-step explanation:

[tex] 5x^2 - 2 = 4x [/tex]

[tex] 5x^2 - 4x - 2 = 0 [/tex]

[tex] x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]

[tex] x = \dfrac{-(-4) \pm \sqrt{(-4)^2 - 4(5)(-2)}}{2(5)} [/tex]

[tex] x = \dfrac{4 \pm \sqrt{16 + 40}}{10} [/tex]

[tex] x = \dfrac{4 \pm 2\sqrt{14}}{10} [/tex]

[tex] x = \dfrac{2 \pm \sqrt{14}}{5} [/tex]

[tex] x = \dfrac{2}{5} + \dfrac{\sqrt{14}}{5} [/tex]   or   [tex] x = \dfrac{2}{5} - \dfrac{\sqrt{14}}{5} [/tex]

Answer: Choice C: none of the above

Step-by-step explanation:

The distance between two numbers would be |(number 1) - (number 2)|

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

Given

Number 1=-3.9

Number 2=-4.7

 |(number 1) - (number 2)|

=|(-3.9) - (-4.7)|

=|-3.9+4.7|

The choice is not available.

Therefore, it is none of the above.

Hope this helps!! :)

Answer:

35 units

Step-by-step explanation:

15/6=2.5

The larger triangle is magnified by a factor of 2.5

Hence its dimensions are 3×2.5=7.5, 5×2.5=12.5 and 6×2.5=15

Perimeter is 7.5+12.5+15=35 units.

6. Factor 4x from 22x2 + 40x 6.​

is that multiply 4x 22x2 +40x6

Answer:

should be the 2nd.............

Answer:

(31, 2); Substitution.

Step-by-step explanation:

x - 3y = 25

Use SUBSTITUTION by setting everything in the above equation equal to x...

x = 3y + 25

2(3y +25) + y = 64

6y + 50 + y = 64

7y + 50 (-50) = 64 (-50)

7y = 14

y = 2

Then, substitute y = 2 into the original equation.

x - 3(2) = 25

x - 6 = 25

x = 31

(x, y) = (31, 2)

Answer:

a.) 0.51

b.) 1445

Step-by-step explanation:

a.) 5.1 x 10^-1 can be written as 5.1 x 0.1 which equals 0.51.

b.) 1.7 x 10^4 x 8.5 x 10^-2 can be simplified either by condensing 10^4 and 10^-2 to equal 10^2, or substituting the expression into a calculator.

This should equal 1.7 x 8.5 x 10^2 or 1445.

Answer:

Step-by-step explanation:

Answer:

x < 6

Step-by-step explanation:

[tex]\frac{x}{3}+4 < 6[/tex]

Subtract 4 form both sides

[tex]\frac{x}{3}<6-4\\\\\frac{x}{3}<2[/tex]

Multiply both sides by 3

[tex]x < 2*3\\\\x < 6[/tex]

option number of b is write

Answer:

Option B is correct.

Step-by-step explanation:

Recall that the domain is the set of (unique) inputs and the range is the set of outputs (which do not have to be unique).

The set of inputs of the given relation is {-1, 9, -10, 1}, and this set is also found in Option B.  The set out outputs is {7, 2, 6, -6|, which is in Option B.

Answer:

The answer is D

Step-by-step explanation:

This is because you multiply two by every number in the parentheses!
