Answer:

10x

Step-by-step explanation:

Since 4x and 6x are like terms you add the numbers as normal then put the x behind it. So it would be 4 + 6 = 10. Now add the x. 10x

Answer:

a- (x-7)(x+9) | b- 193*207 | c- 242*258

Step-by-step explanation:

a)

x^2+2x-63.

the middle number is 2 and the last number is -63.

You would have 2 numbers that add to 2 and multiply to -63.

Those numbers are -7 and 9.

so (x-7)(x+9).

b)

((200)-7)((200)+9)

(193)(209).

You can check this by multiplying 193 by 209 and then doing (200)^2+2(200)-63. Both would equal 40337.

c)

2(x-7)+2(x+9)=1000

(2x-14)+(2x+18)=1000

4x+4=1000

4x=996

x=249.

((249)-7)((249)+9)

(242)(258)

Answer: 1406.25 or 1406 1/4

Step-by-step explanation:

From the question, we are informed that a soccer field at a park is 9000 square yards and that the soccer field takes up 6 2/5 square inches on the map of the park.

To calculate how many square yards does 1 square inch on the map represent, we divide 9000 by 6 2/5. This will be:

= 9000 ÷ 6 2/5

= 9000 ÷ 6.4

= 1406.25 or 1406 1/4

1 square inch on the map represents 1406.25 square yards.

Answer: 45,000 / 32 or 1,406 and 1/4

The total money earned by Marcus in the week is $315.1875.

Given that, Marcus works at a coffee shop. He earns $10.25 each hour.

Decimals are one of the types of numbers, which has a whole number and the fractional part separated by a decimal point. The dot present between the whole number and fractions part is called the decimal point.

1) Number of hours =

6.15+7.15+6+6.45+5 =30.75

2) Money earned in the week

= 30.75×10.25

= $315.1875

Therefore, the total money earned by Marcus in the week is $315.1875.

Answer:

If she is 120 feet below the surface she is -120 feet below the surface. If she goes up by 83 feet she will be 37 feet below the surface. Therfore the answer is -37 feet.

The current dept is 37 feet below the water surface.

A negative sign or minus sign is a mathematical symbol to represents the subtraction between to numbers. It is also used to represent a negative numbers.

The negative or minus sign also indicates movement in the opposite direction on a number line.

According to the given question

Scuba diver is 120 feet below the water surface.

On number line 120 feet below is  represented by -120.

She ascends 83 feet means , she goes up 83 feet up

So, the current depth is calculated as

-120feet + 83feet

= -37 feet.

The negative sign represent that Scuba is 37 feet below the water surface.

Hence, the current dept is 37 feet below the water surface.

Answer:

Basically if you look at the lemonade the bar stops at 12

and for the water the bar stops between 6 and 8 which is 7

and the question says how many more which is minus so

The number of lemonades - the number of water sold=

12-7=5

Answer:

Lemonade sold 5 more than water

Step-by-step explanation:

The question is asking of the difference between lemonade and water that were sold. The graph shows us that 7 water was sold and 12 drinks of lemonade were sold. Since we're finding the difference, the equation would be 12-7, which equals to 5.

Answer:

The simplified algebraic expression to represent the height, h, of a stack in cm of n flower pots is h = 6·n + 22

Step-by-step explanation:

The given information are;

The rim height of one kind of flower pot = 6 cm

The planting height of the flower pot = 22 cm

Therefore, the total height of the flower pot = 22 + 6 = 28 cm

Stacking the flower pots of a single kind will give a linear relationship of the form, y = m·x + c between the height of the stack and the number of flower pots in the stack

Where;

m = The slope or the rate of change of the height with the number of flower pots in a stack which can be found from two points in the given table of values

c = The y-intercept or height at the start of the first stack

From the table of  values, for the first and the last points, we have;

m = (52 - 28)/(5 - 1) = 24/4 = 6

Which gives;

h - 52 = 6×(n - 5)

h = 6·n - 30 + 52 = 6·n + 22

h = 6·n + 22

Where;

h = The height of stack in cm

n = The number of flower pots

Therefore, by comparing to the general form of the equation of a straight line, y = m·x + c, the y-intercept, c = 22

The simplified algebraic expression to represent the height of a stack of n flower pots is therefore given as h = 6·n + 22.

Answer: -22, -28 -34

Step-by-step explanation:

Subtract 6 from every number

Answer:

We subtract 6 each time

-22,-28,-34

Step-by-step explanation:

8,2,-4,-10,-16

8-2 = 6

We subtract 6 each time

2-6 = -4

-4-6 = -10

So it is verified

-16-6 = -22

-22-6 = -28

-28-6 = -34

Answer:

Pat's score is 1.67 standard deviation above the mean

Step-by-step explanation:

We solve using z score formula

z score tells us how much a score deviates from the mean

The formula for calculating a z-score is is z = (x-μ)/σ,

where x is the raw score

μ is the population mean

σ is the population standard deviation.

x = 83

μ = 75

σ = 4.8

z score = 1.66667

Therefore, Pat's score is 1.67 standard deviations above the mean

The property that refers to the density of the medium's particles at the compression of a sound wave is the amplitude of the wave.

The vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid.

amplitude of the wave is the property which represents the density of the medium's particles at the compression of a sound wave.

The maximum displacement of the particles in the medium from their rest position as the wave passes through them is the amplitude of the wave.

Amplitude refers the maximum pressure variation of compression and rarefaction that the sound wave creates in the medium.

Answer:

A = 28

Step-by-step explanation:

You would multiply by 7 on both sides. You multiply by 7 on the right to get rid of the fraction, so you are just left with A on the right. Then you multiply on the left, so it would be 4x7, which equals 28. A=28.

Answer:

56 =a

Step-by-step explanation:

4 = a/7 -4

Add 4 to each side

4+4 = a/7 -4+4

8 = a/7

Multiply each side by 7

8*7 =a/7*7

Given:

w = 250 + 132.5t

The two possible solution to the equation includes

1. If the value of w is given, the w value will be substituted in the equation to find the value of t

2. If the value of t is known , the value of t will be substituted in the equation to find the value of w

That is,

w = 250 + 132.5t

132.5t = w - 250

t = (w - 250) / 132.5

Answer:

6 days ; 2300 calories

Step-by-step explanation:

Given the following :

Current consumption :

Simba = 1520 calories per day

Increases by 130 calories per day : After d days ;

S(d) = 1520 + 130d

Where ; d = number of days

Cuddle = 3380 calories

Decreases by 180 calories each day; after d days ;

S(d) = 3380 - 180d

Pattern continues until they both consume same number of calories each day

S(d) = C(d)

1520 + 130d = 3380 - 180d

130d + 180d = 3380 - 1520

310d = 1860

d = 6

Number of calories they will be consuming them ;

Using : S(d) = 3380 - 180d

S(6) = 3380 - 180(6)

S = 3380 - 1080

S = 2300

They will be consuming 2300 calories by then.
