Combine like terms. First, add 4.2x to both sides. This results in 1.8+0.5x = 0.3, and then 0.5x = 0.3-1.8.
Next, 0.05x = -1.5, or 5x = -150, and x = -30.
Must check this result by substitution of -30 for x in the original equation.
Is 1.8-3.7(-30)=-4.2(-30)+0.3 true or false?
Answer:

Step-by-step explanation:




14(12)+5(6)+16 = 168+30+16=214
This is the correct formula for the problem because you sold 12 maracas, 6 calves, and 1 single drum. You should also put the parenthesis next to the numbers that are being multiplied because you sold multiple of those items.

The Explanatory variable otherwise know as the independent variable in the study is the Ginkgo biloba administered to the students in doses of 250,500 and 1000 milligrams everyday for one month.
Im assuming it would be 60 or 60.375(Work below)
Because usually when it says "out of" it means divide so i divided 8 from 21 and got 2.625 so then i took the 63 and subtracted 2.625 from that and got 60.375 so its either 60 or 60.375 again im not sure if im wrong im very sorry.
