Which of these expressions represents the sum of two rational numbers being rational?
5/+4
√14+2

Answer:

1500

Step-by-step explanation:

18 = 1.2%

100% ÷ 1.2% = 83 and 1/3

1.2% × 83 and 1/3 = 100%

18 × 83 and 1/3 = 1500

Step-by-step explanation:

y=790x-175

Answer:

8

Step-by-step explanation:

3x3x3 which equals 27 and them divide it by 3 which is 9, and subtract -1 from it, which then you have to add so its 10.

Answer:

27/4

Step-by-step explanation:

In this question,

[tex]x = 3 \\ y = - 1[/tex]

So if we substitute this in the equation given below

[tex] {x}^{3} \div 3 - y[/tex]

So if we substitute the variables,

[tex] {3}^{3} \div 3 - ( - 1) \\ [/tex]

[tex]27 \div 4[/tex]

[tex] \frac{27}{4} [/tex]

Answer:

They are both correct. When the fractions are added, the sum is 4/6. 4/6 is not in its simplest form yet. It can be simplified by dividing the numerator and the denominator by 2. When divided by 2, it yields 2/3

Step-by-step explanation:

[tex]\frac{1}{2}[/tex] + [tex]\frac{1}{6}[/tex]

[tex]\frac{3 + 1}{6}[/tex] = 4/6 = 2/3

Answer:

4xy + 6x

Step-by-step explanation:

2xy + 2x + 4x + 2xy

combine like terms:

4xy + 6x

Answer:

Simplified  expression  4 x y + 6 x

Step-by-step explanation:

The slope is 12 and y- intercept is -5.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

y=12x−5

Now, from slope- intercept form

y = mx + b

where m is the slope and b is the y intercept.

Now, Comparing with given equation

m= 12 and b= -5

Hence, the slope is 12 and y- intercept is -5.

Answer:

y = 1

x = 3

Step-by-step explanation:

y = 7 - 2x

x - 2y = 1

5x - 14 = 1

y = 7 - 2x

x = 3

y = 7 - 2x

y = 1

22/35+35x3

Division comes first.

22/35=0.62857142857 or just 0.629, or 0.63

0.63+35x3

Now we multiply.

35x3=105

So now we have 0.63+105.

Lastly, we add.

0.63+105=105.63

The answer is 105.63.

Answer: 15 sq. units

Step-by-step explanation:

Given

Answer:

  (b)  -15

Step-by-step explanation:

The area under the curve from -5 to +5 can be divided into two trapezoids. The one from x=-5 to x=1 has an area of ...

  A = 1/2(b1 +b2)h = 1/2(1 +6)(5) = 17.5

The one from x=1 to x=5 has an area of ...

  A = 1/2(4 +3)(-1) = -3.5

So, the total area from x=-5 to x=+5 is 17.5 -3.5 = 14. This is the amount by which f(x) increases from f(-5) to f(5). That is ...

  f(-5) +14 = -1

  f(-5) = -15

Ratio = 4/7 : 1/8

        [tex]=\frac{\frac{4}{7}}{\frac{1}{8}}\\\\=\frac{4}{7}*\frac{8}{1}\\\\=\frac{32}{7}[/tex]

       = 32 : 7

[tex]\frac{\frac{1}{8}}{\frac{4}{7}}=\frac{1}{8}*\frac{7}{4}\\\\=\frac{7}{32}[/tex]

Ratio 4/7 over 1/8  is the multiplicative inverse of the ratio 1/8 over 4/7
