Answer:
x=14 ; y= √153.
Step-by-step explanation:
1) x=7 / sin30°=14.
2) y=√(x²-7²)=√153.
Answer:
10
Step-by-step explanation:
2x+46+3x-6 = 90
5x + 40 = 90
5x = 50
x =10
Answer:
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−5−5(6x−8)=−5x+19
−5+(−5)(6x)+(−5)(−8)=−5x+19(Distribute)
−5+−30x+40=−5x+19
(−30x)+(−5+40)=−5x+19(Combine Like Terms)
−30x+35=−5x+19
−30x+35=−5x+19
Step 2: Add 5x to both sides.
−30x+35+5x=−5x+19+5x
−25x+35=19
Step 3: Subtract 35 from both sides.
−25x+35−35=19−35
−25x=−16
Step 4: Divide both sides by -25.
−25x
