Answer:
21/7=3
3 times bigger.
Step-by-step explanation:
Answer:
x=-1539/445, y=1724/445. (-1539/445, 1724/445).
Step-by-step explanation:
y=9x+35
y=-8/9x+4/5
-------------------
9x+35=-8/9x+4/5
9x-(-8/9x)=4/5-35
9x+8/9x=4/5-175/5
81/9x+8/9x=-171/5
89/9x=-171/5
x=(-171/5)/(89/9)
x=(-171/5)(9/89)
x=-1539/445
y=9(-1539/445)+35
y=1724/445
Answer:
z≤2
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
−1/8z≥−0.25
Step 2: Multiply both sides by 8/(-1).
(8/−1)*(−18z)≥(8−1)*(−0.25)
z≤2
