Answer:
n = 6.5
Step-by-step explanation:
0.7n - 1.5 + 7.3n = 14.5
0.7n+7.3n=8n
8n-1.5=14.5
+1.5 = +1.5
---------------------
8n/8(divide) = 16/8
n=8
Answer:
33.5
-by-step explanation:
8.5 + (12 + 4) × 2 - 7
Use PEMDAS ( I think this is right hope it helps!)
Answer:
x = 8
y = 14
Step-by-step explanation:
2x + 6 = 4x - 10 (Corresponding angles so they're equal)
2x - 4x = -10 - 6
-2x = -16
x = 8
2x + 6 + 13y - 24 = 180 (Supplementary angles so they add up to 180)
2(8) + 6 + 13y - 24 = 180
16 + 6 + 13y - 24 = 180
13y - 2 = 180
13y = 182
y = 14
Answer:
7x-1
