Answer:
(12, 487)
Step-by-step explanation:
y = 3.7x + 442 ----› Eqn. 1
y = 14.4x + 312 ----› Eqn. 2
Substitute y = (3.7x + 442) into eqn. 2.
y = 14.4x + 312 ----› Eqn. 2
3.7x + 442 = 14.4x + 312
Collect like terms
3.7x - 14.4x = -442 + 312
-10.7x = -130
Divide both sides by -10.7
x = 12.1495327
Substitute x = 12.1495327 into eqn. 1.
y = 3.7x + 442 ----› Eqn. 1
y = 3.7(12.1495327) + 442
y = 486.953271
The solution to the system is rounded to the nearest integer:

Answer:
1 sandal= $7
1 flip flop =$2.5
Step-by-step explanation:
say one sandal costs x and one flip flop costs y
3 x+y=23.50
4x+2y=33
solve using simultaneous equationsto find the values of x and y
Area = 267
perimeter = 72
area- solve for the area of the 18 by 10 section, then the area of the 7 by 21 section. once you have those, determined the size of the shared area between those two and subtract from one of them.
perimeter- just add

Answer:4/15
Step-by-step explanation:
1. multiply and divide (left to right)3/5
=3/5-1/3
2.multiply and divide (left to right) 1/3
=3/5-1/3
3.add and subtract (left to right) 3/5-1.3:4/15
=4/15
