Three-fourths of the sum of six times a number and twelve distribute

Mathematics
1 answer:
dimaraw [331]3 years ago
6 0

Answer:

Step-by-step explanation:

Let x be the number.

6 times the number = 6*x = 6x

Sum of 6 times of a number and twelve = 6x + 12

Three-fourths of the sum of 6 times of a number and twelve = \frac{3}{4}(6x +12)

\frac{3}{4} ( 6x + 12) = \frac{3}{4}*6x + \frac{3}{4}*12\\\\

                = \frac{3}{2}*3x + 3*3\\\\=\frac{9}{2}x + 9

32S+3T=$127 . Multiply this by 2.

64S+6T=$254 Subtract this below

.

25S+2T=$97.50 . Multiply this by 3.

75S+6T=$292.50

64S+6T=$254 . Subtract this (from above.)

.

11S=$38.50

S=$3.50

ANSWER 1: Student tickets cost $3.50.


.

32S+3T=$127

32($3.50)+3T=$127

3T=$15

T=$5.00

ANSWER 2: Teacher tickets cost $5.00.
