Answer:1
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :
-2*x+5-(7)<0

Answer:
a = 4.6
b = 4.2
Step-by-step explanation:
to find a, use cos:
⇒ cos = 
⇒ cos 30 = 
cos of 30 is 0.154
⇒ 0.154 =
multiply 13 on both sides:
⇒ 0.154 x 13 = x 13
⇒ 4.62 = a
round to the nearest tenth:
⇒ 4.62 = 4.6
⇒ a = 4.6
to find b, use tan:
⇒ tan = 
⇒ tan 60 = 
tan of 60 is 0.320
⇒ 0.320 =
multiply 13 on both sides:
⇒ 0.320 x 13 = x 13
⇒ 4.16 = b
round to the nearest tenth:
⇒ 4.16 = 4.2
⇒ b = 4.2
Answer:No.
amount of paint needed for 1 coat = 750 ml
amount for 3 coats = 750 ml * 3 = 2250 ml
=2.25 litre
hence we've 0.25 litre less
Step-by-step explanation: hope this helps
