Step-by-step explanation:

These are "one-step" equations.

To solve the ones involving addition or subtraction, identify the constant on the same side with the variable. Add its opposite to both sides.

To solve the ones involving multiplication or division, identify the coefficient of the variable. Multiply both sides by its reciprocal (or, equivalently, divide by that coefficient).

Here are more details for the problems on the first page.

Answer:

23

Step-by-step explanation:

From the graph, derive the best fit equation :

Using the points ;

(0,2.5)  (100 ,35)

x1 = 0 ; y1 = 2.5 ; x2 = 100 ; y2 = 35

Slope formula, m = (y2-y1)/(x2-x1)

m = (35-2.5)/(100-0)

m= (32.5)/100

m = 0.325

The y intercept, value on the graph where best fit line crosses the y axis = 2.5

The equation :

y = mx + c

c = intercept ; m = slope

y = 0.325x + 2.5

y = Number of cars

x = number of customers

The number of customers if there are 10 cars parked :

10 = 0.325x + 2.5

10 - 2.5 = 0.325x

7.5 = 0.325x

x = 7.5 / 0.325

x = 23.076

x = 23

Answer:

[tex]x=-\frac{3\sqrt{2}}{2},\frac{3}{4},\frac{3\sqrt{2} }{2}[/tex]

Step-by-step explanation:

Given expression is,

f(x) = 8x³ - 6x² - 36x + 27

For zeros of the function,

f(x) = 0

8x³ - 6x² - 36x + 27 = 0

2x²(4x - 3) - 9(4x - 3) = 0

(2x² - 9)(4x - 3) = 0

(2x² - 9) = 0

x² = [tex]\frac{9}{2}[/tex]

x = [tex]\pm\frac{3}{\sqrt{2}}[/tex]

x = [tex]\pm \frac{3\sqrt{2}}{2}[/tex]

Or (4x - 3) = 0

x = [tex]\frac{3}{4}[/tex]

Therefore, all zeros of the given functions are  [tex]x=-\frac{3\sqrt{2}}{2},\frac{3}{4},\frac{3\sqrt{2} }{2}[/tex].

You need to add 3 5/9 to make 8. If you want to know what 4 4/9 goes to, to make 8, do the opposite which is subtracting. 8 turn to 7 9/9 and then subtract 4 4/9 and then you get the answer aka 3 5/9.

Answer:

16e-9

Step-by-step explanation:

===============================================================

In order to simplify this expression, we need to combine like terms:-

[tex]\longrightarrow\sf{6e+10e-9}[/tex]

Add the e's:-

[tex]\longrightarrow\sf{16e-9}[/tex]

Are there any more like terms? No, because 16e and -9 aren't like terms.

====================================================

Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I will comment and/or edit my answer :)

Answer:

Answer:

600 - 0.082 = 599.918

Answer:

1.040

Step-by-step explanation:

log √(120)

= (1/2) log 120

120 = 2³ • 3 • 5

= 0.5(3 log 2 + log 3 + log 5)

Express log 5 in terms of log 2.

log 5 = log (10/2) = log 10 - log 2 = 1 - log 2

= 0.5(3 log 2 + log 3 + 1 - log 2)

= 0.5(2 log 2 + log 3 + 1)

= 0.5(2*0.3010 + 0.4771 + 1)

= 1.03955 or 1.040

Answer:

1=6

7=42

2.5=15

5=30

Step-by-step explanation:

Multiply each original value by the scale factor

1×6=6

7×6=42

2.5×6=15 (2×6 + 6×0.5)

5×6=30

Answer:

Original: 5 cm = Enlarged: 30 cm

Original: 7 cm = Enlarged: 42 cm

Original: 2.5 cm = Enlarged: 15 cm

Original: 1 cm = Enlarged: 6 cm

Answer:

40, 15, 2.5

Step-by-step explanation:

If there are 10 kilos in 22 pounds, we have to divide Fido's weight by 22. 88/22 is 4 meaning there are four sets of 10 kilos making 40.

If 22 pounds is 1 kilogram, and half a kilogram is 11 pounds, we kmow thaat 22 + 11 equals 33.

Bella weighs one foruth or a quarter of 22. Meaning he is a quarter of 10 kilograms giving us 2.5

Answer:

2 / 13

Step-by-step explanation:

Number of cards in a standard deck = 52

Number of 4's = 4 ( 1 for each suit)

Number of 6's = 4 (1 for each suit)

Probability, P = required outcome / Total possible outcomes

P(a 4) = 4 / 52 = 1/ 13

P(a 6) = 4 /52 = 1/13

Probability of either a 4 or a 6

P(a 4) + P(a 6)

1/13 + 1/13

= 2 / 13

Answer: 24 grams of element would remain.

Step-by-step explanation:

Exponential function for decay:

[tex]f(x)=Ab^{\frac{x}{n}}[/tex] ....(i) , where A = initial value , b = decay factor, x = time , n= time per period

As per given,

A = 569 grams , [tex]b=\dfrac12[/tex]

n= 5 years, t = 23 years

Put all values in (i) , we get

[tex]f(23)=590(\dfrac12)^{\frac{23}{5}}\\\\\\=590\times 0.0412346222117\\\\=24.3284271049\approx 24[/tex]

Hence, after 23 years , 24 grams of element would remain.

Answer:

[tex]\sqrt{210/16}[/tex]  

Step-by-step explanation:

By saying reach the ground, it means the altitude w[tex]\sqrt{}[/tex]ill be zero, so the equation will be: 210 - 16t^2 = 0

210 = 16t^2, t = [tex]\sqrt{210/16}[/tex]  

Answer:

Each point is 4 units away from the y-axis.

Step-by-step explanation:

Coordinates of point (x, y) defines the distance of the point from y-axis and x-axis.

x-coordinate → distance from the y-axis

y-coordinate → distance from x-axis

Coordinates of A → (-4, 3)

Coordinates of B → (-4, -3)

So both the points have same x-coordinates but opposite y-coordinates.

Therefore, each point is 4 units away from the y-axis.
