Yes he is right because if u have

-6 -(-4) u would multiply the 2 signs the - and the -4 and u would get +4

then ur equation becomes -6+4 = -2

Can you guys help? Hopefully the last question of the day/night!

Anettt [7]

Answer and explain:

1st person: 70 % throws

70/100x80 = 56 out of 80 throws

2nd person: 60% throws

60/100x80 = 48 out of 80 throws

3rd person 50% throws

50/100x80 = 40 out of 80 throws

56+48+40/80x3 = 77/120

One equation that gives the estimated number of free throws (all the 3 people) is 77 out of 120. The best player will make about 56 out of 80 free throws.

For the diagram at right, write and solve an equation to find x

Tomtit [17]

Answer:

x = 24

Step-by-step explanation:

The formula for determining the sum of interior angles is:

$(n-2) * 180$

$4 * 180 = 720$

Therefore to determine an equation for x, we must add up all the interior angle equations and set them equal to 720.

$(2x+3) +(3x+12) + (7x+14) + (9x+2) + (4x+8) + (3x+9) = 720\\28x + 48 = 720\\28x = 672\\x = 24$

The equation and answer above shows how to find x, which equals 24.

If x€{-2,-1,0,1,2,3,4,5} find the solution set 7-x>0 ii 3-4x>-2 vi 3x+4>-2

maw [93]

Answer:

i) {-2 , -1 , 0 , 1 ,2 , 3 , 4 , 5}

ii) {-2 , -1 , 0 , 1}

iii) {-1 , 0 , 1 ,2 , 3 , 4 , 5}

Step-by-step explanation:

i) 7 - x > 0

⇔ 7 > x

⇔ x < 7

⇔ x ∈ {-2 , -1 , 0 , 1 ,2 , 3 , 4 , 5}

____________________________

ii) 3 - 4x > -2

⇔ 3 + 2 > 4x

⇔ x < 5/4

⇔ x ∈ {-2 , -1 , 0 , 1}

____________________________

iii) 3x + 4 > -2

⇔ 3x > -2 - 4

⇔ 3x > -6

⇔ x > -6/3

⇔ x > -2

⇔ x ∈ {-1 , 0 , 1 ,2 , 3 , 4 , 5}
