Answer:
I'm pretty sure its b>2
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
3>−b+5
Step 2: Flip the equation.
−b+5<3
Step 3: Subtract 5 from both sides.
−b+5−5<3−5
−b<−2
Step 4: Divide both sides by -1.
-b/-1 < -2/-1
Answer:
b>2
Answer:
x=1 y=-5
Step-by-step explanation:
7(5x-2y=15) ---> 35x-14y=105
2(7x+7y=-28) --> + <u>14x+14y=-56</u>
49x=49 --->x=1
5(1)-2y=15 ---> 5-2y=15 ---> -2y=10 ---> y=-5
Answer:
R = 6S/T
Step-by-step explanation:
R ∝ S/ T
》R = kS/ T
》k = RT/ S
If R = 8 when S = 4 and T = 3
then, k = (8 × 3)/ 4
k = 6
∴ R = (6 × S)/ T
