musickatia [10]3 years ago
5 0

answer:

1. yes

2. no

3. yes

4. no

step-by-step explanation:

  • for 1, yes because no matter what they are the signs are still the same
  • for 2, no because the signs have changed — 2/5 is positive now
  • yes because even though there is addition now, the signs are the same. when you use kcc (keep change change), the sign changes to +
  • no, because the coefficient for p is changed, which won't be true or give us the same result

Solve the following:<br> a) 4x-1 / 2= x+7<br> b)<br> 3x + 2 = 2x + 13 /3
11Alexandr11 [23.1K]

Answer:

a) 2.5

b)2.33

Step-by-step explanation:

a)

4x-\frac{1}{2}= x+7

Bring the numerals to the right hand side and the x terms to the left hand side

4x-x=7+\frac{1}{2}

Simplify

3x=\frac{15}{2}

Divide 3 on both sides, to get x

x=\frac{5}{2} =2.5

b)

3x+2=2x+\frac{13}{3}

Bring the numerals to the right hand side and the x terms to the left hand side

3x-2x=\frac{13}{3}-2

Simplify

x=\frac{7}{3} =2.33

sertanlavr [38]

Answer:

w > -3

Step-by-step explanation:

2w<9+5w

Subtract 5w from each side

2w-5w<9+5w-5w

-3w <9

Divide each side by -3 remembering to flip the inequality

-3w/-3 > 9/-3

The sum of the angle measures of any triangle is 180 degrees. Angle 2 is twice the measure of angle 1. Angle 3 is 15 degrees les
allochka39001 [22]

Answer:

Angle 1 = 39, Angle 2 = 78 , Angle 3 = 63

Step-by-step explanation:

78/2 = 39

(Angle 2/2 = Angle 1)

78 - 15 = 63

(Angle 2 - 15 = Angle 3)

39 + 78 + 63 = 180

(Angle 1 + Angle 2 + Angle 3 = 180)
