79 / 10 = 7.9
Hope that helps...
Answer:
10
Step-by-step explanation:
40=2a<u>-3</u>+2a+3a<u>+1</u>
add like terms
get 'a' by its self
- 40(+2)=7a<u>-2(+2)</u> [2 cancels out]
- 42(÷7)=7a(÷7) [7 cancels out]
- a=6
plug in the answer for Equations
- biggest: 3(6)+1= 18+1= 19
- smallest: 2(6)-3= 12-3=9
subtract smallest from biggest
Answer:
-3
Step-by-step explanation:
The answer would be 12x-15
Answer:
b ≈ 9.5, c ≈ 14.7
Step-by-step explanation:
Using the Sine rule in Δ ABC, that is
=
, substitute values
=
( cross- multiply )
b × sin23° = 7 × sin32° ( divide both sides by sin23° )
b =
≈ 9.5 ( to the nearest tenth )
Also
= 
=
( cross- multiply )
c × sin23° = 7 × sin125° ( divide both sides by sin23° )
c =
≈ 14.7 ( to the nearest tenth )
