Answer:
a > -2
Step-by-step explanation:
-12a +7<31
Subtract 7 from each side
-12a +7-7<31-7
-12a <24
Divide by -12, remembering to flip the inequality
-12a/-12 >24/-12
a > -2
Answer:$30
Step-by-step explanation:
Divide 5 from 1.50 and get $30
4(x÷9)=2
4 is multiplied to the (x÷9) to get your answer of 2
Step-by-step explanation:
sin(A − B) = sin A cos B − cos A sin B
sin50°cos 40° - cos50°sin 40°
= sin(50-40)°
=sin10°
cos(A + B) = cos A cos B − sin A sin B
cos75°cos 15° - sin75°sin 15°
= cos(75+15)° = cos90° = 0
Answer: y = 5
using pythagoras theorem
Step-by-step explanation:
If y = 5 there is sufficient information to show that triangle ABC = triangle DEF using the Pythagoras theorem.
