There are 10 desks, 12 chairs and 4 cabinets. What's the ratio of chairs to all
items?

Step-by-step explanation:

By simply adding all of the items, you end up with 10 + 12 + 4, or 26 items.  Then, simply set the number of chairs to the number of total items, or 12 : 26.  This ratio can also be expressed as the fraction 12/26, and can be simplified into 6/13, or 6 : 13, by dividing both the numerator and denominator by 2.

Hope it helps :) and let me know if you want me to elaborate.

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316
