The value would be -4.

Since 7+ (-2)= 5, you would have to do -2 x 3 to get -6 then you would subtract 2 since the numbers -6 and 2 have different signs. Hope this helps. Happy Thanksgiving.

Let n (AUB)=32n(B)=16and n(ANB)9 find n (A)​
Lubov Fominskaja [6]

Answer:

32

Step-by-step explanation:

n(A∪B)=n(A)+n(B)−n(A∩B)−−−−−−−(1)

Given n(A)= ? we represent with x

n(B)= 16

n(A∪B) = 32

Substituting in equation 1 to get n(A)

32  = n(A) + 9 − 9

⇒n(A) = 32 − 0

n(A)  = 32

to confirm this we put the values into the formula below

n(A∪B)=n(A)+n(B)−n(A∩B)−−−−−−−(1)

32 =  32 + 9 - 9

Not sure how to find what x equals
Llana [10]

Answer:

Its 48 °

Since its a triangle, the total angle will be 180°

So,

x° + 42°+90°=180°(90° as one angle in triangle is 90°)

x°=180°-90°-42°

x°=48°

Solve linear equations <br><br> Solve for x <br><br> -2(4x + 3) = 3(x + 1)
inna [77]

Answer:

x = - \frac{9}{11}

Step-by-step explanation:

Given

- 2(4x + 3) = 3(x + 1) ← distribute parenthesis on both sides

- 8x - 6 = 3x + 3 ( subtract 3x from both sides )

- 11x - 6 = 3 ( add 6 to both sides )

- 11x = 9 ( divide both sides by - 11 )

x = - \frac{9}{11}

if ur supposed to add them then

1. 1/8 + 8/8 + 3/8 = 12/8 = 1 1/2

2. 1/4 + 2/4 + 1/4 = 4/4 = 1

3. 1/8 + 8/8 + 4/8 = 1 5/8

4. 1/4 + 1/4 + 2/4 = 4/4 = 1

5. 1/4 + 1/4 + 1/4 + 1/4 = 1
