Solve the following equations : 2(x -1) + 3(x +1)=4(x+4)

Mathematics

madreJ [45]3 years ago

This is how I'd work it:

2(x-1)+3(x+1)=4(x+4)
     2x-2+3x+3=4x+16
              5x+1=4x+16
                    <u>x=15</u>

To check, substitute x into the original equation and solve: 

2(15-1)+3(15+1)=4(15+4)
                28+48=76
                      76=76

Your beginning balance on your lunch account is $42. You buy lunch for $1.80 every day and sometimes buy a snack for $0.85. Afte
tangare [24]

Answer:

The answer to your question is: I bought 7 snacks

Step-by-step explanation:

Data

beginning balance = $42 = b

lunch = $1.80  = l

snack = $ 0.85  = s

final balance = $0.05 = f

                        f = b - 1.8l - 0.05s

                     0.05 = 42 - 1.8l - 0.85s

After 20 days I spent = 1.8(20) in lunches = $36

                    0.05 = 42 - 36 - 0.85s

                   0.05 = 6 - 0.85s

                  0.05 - 6 = -0.85s

                  -5.95 = -0.85s

                  s = -5.95/-0.85

                  s = 7

which simplifies to 4d+24

17/13 = y/10 solve for y and round to the nearest tenth
11Alexandr11 [23.1K]

\frac{17}{13}  =  \frac{y}{10}

17 \times 10 = y \times 13

170 = 13y

y =  \frac{170}{3}  = 56.6666....

56.6666... to the nearest tenth is <u>57</u>.
