2x - (-8) - 7x + 4 +10

2 answers:

7 0

You add a 1 where the first negative is so when you multiply that’s -1 times -8 so that’s positive 2x + 8. Then you add the numbers up that don’t have a variable and you come up with 2x + 22 - 7x. Then you combine like terms to get -5x + 22. And that’s your answer.

Answer:

-5x+22

Step-by-step explanation:

we are simplifying

2x-(-8)-7x+4+10=

2x+8+-7+4+10=

2x+8+-7x+4+10

(2x+-7)+(8+4+10)= -5x+22

Answer:

36.36% probability that she gave birth to quadruplets

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcoes.

Desired outcomes:

Giving births to quadruplets.

She has 4 sets of quadruplets.

So $D = 4$

Total outcomes:

At least 3 children(triplets).

7 sets of triplets and 4 sets of quadruplets.

So $T = 7 + 4 = 11$

Probability:

$p = \frac{D}{T} = \frac{4}{11} = 0.3636$

36.36% probability that she gave birth to quadruplets

Answer:

∡ABC=55°

Step-by-step explanation:

Step 1: Identify all angles

∠A=(x+45)°

∠B=(6x+5)°

∠C=(3x)°

∠ABC=(180-∠B)°=(180-(6x+5))°

Step 2: Use the Triangle Angle Sum Theorem

∠A+∠ABC+∠C=180°

(x+45)+(180-(6x+5))+(3x)=180

x+45+180-6x-5+3x=180

-2x+45+180-5=180

-2x+45-5=0

-2x+40=0

-2x=-40

x=20

Step 3: Plug in x=20 for ∠ABC

∠ABC=(180-(6x+5))°

(180-6(20)-5)°

(180-120-5)°

(60-5)°

55°

So ∡ABC=55°
