Answer:

61

Step-by-step explanation:

8-(36/9)+99-(6x7)

8-4+99-42

4+57

Answer:

11

Step-by-step explanation:

For this, we need to follow PEMDAS (Parenthesis, exponent, multiply/divide, add/subtract). First, we do the parenthesis, this gets us 8 - 4 + 49 - 42. Since this is all addition/subtraction, we do it from left to right. 8-4 is 4. Now our equation is 4 + 49 - 42. 4 + 49 is 53. Now our equation is 53 - 42. That is 11. That means our answer is 11.

Answer:

Step-by-step explanation:

Answer:

a=12

Step-by-step explanation:

we need the slope of this line. Find it with the slope formula

m= y2-y1 / x2-x1    with the points given p1=(-8,7)  and p2=(-11,-11)

m=-11-7 / -11-(-8)                                               (x1,y1)               (x2,y2)  

m= -18 /-11+8

m= -18 / - 3

m= 6

next plug in one of the point into the point-slope formula [y-y1=m(x-x1)]

y-7=6(x-(-8))  ( simplify this towards the slope intercept form [y=mx+b]

y-6=6(x+8)

y-6=6x+48

y=6x+54

now we can plug in our point of (-7,a) to find what a is

a=6(-7)+54

a=-42+54

a=12

Answer:

-26 should be the answer.

Step-by-step explanation:

-2 (-3x + 5) - 2 (x + 4)

-2 (-3(-2) + 5) - 2 ((-2) + 4)

-2 (6 + 5) - 2 ((-2) + 4)

-2 (11) - 2 ((-2) + 4)

-2 (11) - 2 (2)

-22 - 2 (2)

-22 - 4

-26

Answer: 4983

Step-by-step explanation:

Initial population P=5500

Population declining at the rate of 1.4%

So, in the year 2010 population is

[tex]P=5500-5500\times1.4\%=5500(1-1.4\%)[/tex]

For the year 2011

[tex]P=5500(1-1.4\%)^2[/tex]

similarly, for the year 2016

no of years passed 2016-2009=7 years

[tex]P=5500(1-1.4\%)^7[/tex]

[tex]P=5500\times0.986^7\\P=5500\times0.90602\\P=4983.117\approx 4983[/tex]

Answer:

x = 10

Step-by-step explanation:

From what we can see in the diagram, the smaller triangle dimensions were dilated by a factor of 3

So to get the dimensions of the smaller from the bigger or larger triangle, we proceed to divide what we have on the larger triangle by 3

Kindly note that we do this for the comparable sides

Mathematically, we can have x as;

30/3 = 10

Answer:

The formula for total earning is T = £22h

Step-by-step explanation:

Given that:

Per hour earning of Tom = £10

Per hour earning of Tom's wife = £10 + £2 = £12

Let,

T represent their total earnings

h be the number of hours

Total earnings = (Tom's per hour earning + His wife's per hour earning) * Number of hours

T = (£10+£12)h

T = £22h

Hence,

The formula for total earning is T = £22h

Answer:

42 books.

Step-by-step explanation:

What the question's really asking is 63 * 2/3, since 2/3 is all that's left after she donates 1/3 of her books. ( 63 / 3 ) * 2= 42.

Therefore, Alice will have 42 books remaining.

Answer:

Step-by-step explanation:

Step-by-step explanation:

( 63 / 3 ) * 2= 42. Therefore, Alison will have 42 books remaining.

Answer:

About 7 miles a day?

Step-by-step explanation:

53.2-10= 43.2

43.2 divided by 6 is  about 7.6. I’m just in middle school though :)

Colton will have to ride 7.2 miles per day on other to hit his target.

Total miles to ride = 53.2

Miles ridden already = 10 miles

Number of days left to ride = 6 days

The average ride per day will be:

Hence, Colton will have to ride 7.2 miles each day.
