Answer:
PQ is perpendicular to RS
that is to mean:
PQ⊥RS
Step-by-step explanation:

Refine:

Multiply both sides by 3 :

Refine:

Subtract 15 from both sides:


Divide both side by -2 :


hope this helps!.
The LCM of 5,20,30,& 35 is 140
Answer:
None of the above
Step-by-step explanation:
To find the GCF of something find the prime factorization of each number, then see which numbers are the same. After that multiply the numbers that are the same.
(PF): Prime Factorization
A: PF - 1 PF - 2 · 3 (Since they don't have any numbers in common the GCF is 1)
B: PF - 2 PF - 3 (The GCF is also 1)
C: PF - 2 PF - 2 · 3 (Because they have 2 in common the GCF is 2)
D: PF - 3 PF - 2 & 2 (The GCF is 1)
None of the options have a GCF of 3. Therefore it is none of the above
Answer:
Let's solve your equation step-by-step.
−3.1x+7−7.4x=1.5x−6(x−

)
Step 1: Simplify both sides of the equation.
−3.1x+7−7.4x=1.5x−6(x−

−3.1x+7+−7.4x=1.5x+(−6)(x)+(−6)(

)(Distribute)
−3.1x+7+−7.4x=1.5x+−6x+9
(−3.1x+−7.4x)+(7)=(1.5x+−6x)+(9)(Combine Like Terms)
−10.5x+7=−4.5x+9
−10.5x+7=−4.5x+9
Step 2: Add 4.5x to both sides.
−10.5x+7+4.5x=−4.5x+9+4.5x
−6x+7=9
Step 3: Subtract 7 from both sides.
−6x+7−7=9−7
−6x=2
Step 4: Divide both sides by -6.
−6x. /−6
