Find the value of y in the formula y=5a-3b c, if a=12,b=4,c=8

liberstina [14]

Y=5a-3b
Y=5(12)-3(4)
Y=60-12
Y=48

You don't have a sign between b and c in the equation, so I cannot help you with the last operation

Round your answer to the nearest hundredth AC=

KatRina [158]

Answer:

AC ≈ 2.96

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos65° = $\frac{adjacent}{hypotenuse}$ = $\frac{AC}{AB}$ = $\frac{AC}{7}$

Multiply both sides by 7

7 × cos65° = AC , thus

AC ≈ 2.96 ( to the nearest hundredth )
