Idk I'm learning that also
Answer: F=bill for first shop=4S-$630; S=bill for second shop
.
F+S=$3265 Substitute for F
4S-$630+S=$3265
5S=$3895
S=$779 ANSWER 1: The bill for the second shop was $779
.
F=4S-$630
F=4($779)-$630
F=$3116-$630=$2486 ANSWER 2: The bill for the first shop was $2486.
.
CHECK:
F+S=$3265
$2486+$779=$3265
$3265=$3265
explanation:
If you let x represent the number of free throws.
let y represent the number of two-point field goal.
let z represent the number of three-point shots made.
Then the correct system of linear equations is as follows:
x + 2y + 3z = 29 (The total number of points scored is 29.)
z = 3x - 29 (The number of 3-pointers was 29 less than 3 times the number of free throws.)
2y = z + 15 (Twice the number of 2-point shots made was 15 more than the number of 3-pointers.)
Solution:
This basketball player scored 10 points via free throws (10 at 1 point each), 16 points via 8 two-point shots made, and 3 points via 1 three-point shots made. So, in the choice its letter D.
Answer:
30 i think because he has done numbers from 1 -30, which are all integers except for decimals...
You can rename it by 10/25. The sum would be 21/25
