All you do is multiply 8 by 2.54, you get 20.32. Your answer is 20.32cm
Answer:
45
Step-by-step explanation:
4/5 t = 36
Divide both sides by 4/5
4/5 / 4/5 t = 36/4/5
4/5 cancels 4/5
Also flip the divisor 4/5
t = 36x5 / 4
= 180/4
= 45
Answer: x=6
Y=6
Step-by-step explanation:
Using the elimination method
3x+5y=48.....equ1
-3x+5y=12......equ2
Add equation 1 &2
3x+5y=48
+
-3x+5y=12
Answer =
10y=60
Y=60/10
Y=6
Substitute for y in equation 1
3x+5y=48
3x+5(6)=48
3x+30=48
3x=48-30
3x=18
X=18/3
X=6
Therefore,
X= 6
Y= 6
Answer:
b= 322.8
Step-by-step explanation:
10.50a + 3.75b = 2071.50
10.50 (82) + 3.75b = 2071.50
861 + 3.75b = 2071.50
-861 -861
3.75b = 1210.5
/3.75 /3.75
b = 322.8
Answer:
t > 1380
Step-by-step explanation:
Subtract 7200 from both sides
10t + 7200 - 7200 > 21000 - 7200
Simplify
10t > 13800
Divide both sides by 10
10t/10 > 13800/10
Simplify
t > 1380
