Answer: the cost would be the same for 12 shirts.
Step-by-step explanation:
Let x represent the number of shirts for which the cost would be the same.
One company charges $9.65 per shirt plus a setup fee of $43. This means that total amount charged for x shirts would be
9.65x + 43
Another company charges $8.40 per shirt plus a $58 fee. This means that total amount charged for x shirts would be
8.4x + 58
For both costs to be the same, the number of shirts would be
9.65x + 43 = 8.4x + 58
9.65x - 8.4x = 58 - 43
1.25x = 15
x = 15/1.25 = 12
Answer:
(- 2, 9 )
Step-by-step explanation:
Under a reflection in the line y = x
a point (x, y ) → (y, x ), thus
(9, - 2 ) → (- 2. 9 )
The boxes checked are right
a) true: In some instances, an irrational number can be added to an irrational number to become rational, but adding a rational number to one will not work
b) false: It only sometimes works
c) true: e.g. square roots --> (√5)² = 5
d) true: a rational number multiplied by any rational number will be rational
e) false: e.g. perfect squares --> √64 = 8
f) true: e.g. √(5/3) = (√5)/(√3) = (√5*√3)/3
30.05 times 10= 300.5 you just move the decimal point further back
