Let's do both. For the first one, we can add 1 to both sides using the property of equality, and get 4x < -12. Then, we divide by 4, getting us x<-3. For the second, we subtract 3 from both sides to get -2x < 4. Then, we divide by -2 on both sides, but when we divide by a negative we have to switch the sign. So, we get x > -2. Hope this helps.
Answer:
Cost of Trumpets: $174
Cost of Clarinets: $149
Cost of Violins: $89
Step-by-step explanation:
Got it correct
6x + 4x+6 + 8x+3 = 63
6x+4x+8x = 63 - 3 - 6
18x = 54
x = 54/18
x = 3
Side AB = 6(3) = 18
Side AC = 4(3)+6 = 18
Side BC = 8(3)+3 = 27
Answer:
8 quarts
Step-by-step explanation:
<u>Step One: Figure out how much 40% is by making an equation:</u>
<em>Since we are looking for a percentage, we use cross multiplication to find X.</em>
<u>Step Two: multiply 20 by 40 to start cross multiplying:</u>
<em>20 times 40 is 800, so replace the 40 by 800 in the equation.</em>
<u>Step Three: divide 800 by 100, and we will have X:</u>
<em>800/100=8</em>
<em><u>X=8 aka 8 quarts</u></em>
I hope this helps!
pls give thx and brainliest :D
