Answer: 3x - 3

Step-by-step explanation:

Each bag contained x counters and there are 3 bags.

He removes one counter from each of the 3 bags so the expression for the counters in each bag is now;

= x - 1

As there are 3 bags, the expression is;

= 3 * ( x - 1)

= 3x - 3

Answer:

[tex]\frac{\sqrt{3} }{2}[/tex]

Step-by-step explanation:

Given

sin(- 240°)

To obtain the positive angle measure add 360°, equivalent to one full revolution about the origin, then

ain(- 240°)

= sin(- 240 + 360)°

= sin120°

= sin( 180 - 120)°

= sin60°

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

Answer: For an oblique or acute triangle sure but not a right triangle

Step-by-step explanation: I guess the sides would work on a regular non right triangle but Pythagorean theorom doesn't work here so the sides don't work for a right triangle

Answer:

Step-by-step explanation:

since the two smaller numbers don't add up to more than the bigger they can. but not a right triangle   :|

Answer:

Step-by-step explanation:

y = ax² + bx + c

a( - 7)² + b( - 7) + c = 134 ⇔ 49a - 7b + c = 134 ......... (1)

a( - 3)² + b( - 3) + c = 10 ⇔ 9a - 3b + c = 10 ......... (2)

a(5)² + b(5) + c = 50 ⇔ 25a + 5b + c = 50 ......... (3)

(1) - (2)

40a - 4b = 124 ⇔ 10a - b = 31 ........... (4)

(3) - (2)

16a + 8b = 40 ⇔ 2a + b = 5 ........... (5)

(4) + (5)

12a = 36 ⇒ a = 3

2(3) + b = 5 ⇒ b = - 1

9(3) - 3( - 1) + c = 10 ⇒ c = - 20

y = 3x² - x - 20

y = [ 3 ] x² + [ - 1 ] x + [ - 20 ]

Answer:

I would start by adding/subracting the values in the numerator. by doing this you will get [tex]\frac{2}{4-2+3}[/tex] . Then do the same thing on the bottom to get [tex]\frac{2}{-1}[/tex] or -2

Answer:

T= y+ 3y-7  

Step-by-step explanation

I'm pretty sure you can also write T= 4y-7 as a simplified form of the equation

The formula for T in terms of y can be written as;

T= y+ 3y -7  

An equation is an expression that shows the relationship between two or more numbers and variables.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

Given that Dawn is y years old.

So, Rashid is three times as old as Dawn means R = 3y

Hugo is seven years younger than Dawn means H = y - 7

The total of Dawn's age, Rashid's age and Hugo's age is T years.

We can also write T= 4y-7 as a simplified form of the equation

Step-by-step explanation:

Answer:

11    n+7=18

31    n-9=22

7      5xm=35

50    m/5=10

15     18+s=33

17     40-s=23

3      27=9xs

6      18/s=3

5       m+m+12=22

2       m+14=18-m

Step-by-step explanation:

11: n+7=18

7: 5 x m =35

50: m/5 = 10

17: 40-s=23

3: 27= 9 x s

6: 18/s = 3

5: m+m+12 = 22

2: m+14 = 18-m

hope this helps!! :)

Step-by-step explanation:

here,

x1= -5. x2=4

y1= -22. y2=r

slope(m)=3

now we have,

m=(y2-y1)/(x2-x1)

or,3=(r-(-22))/(4-(-5))

or,3=(r+22)/(4+5)

or,3=(r+22)/9

or,27=r+22

or,r=27-22

or,r=5
