Answer:
3240
Step-by-step explanation:
If the simple interest is 8%, Mr. Kim will have to pay $3000, and the simple interest, which will be 8% of $3000.
You can write it in two ways:
3000+3000*0.08= 3240
or
3000*1.08= 3240
4x + 3y = 65
X + y = 18
When you use elimination, multiply the second equation by -3
4x + 3y = 65
-3X -3y = -54
X = 11
X+y = 18
11 + y = 18
Y = 7
Answer:
z=-5
Step-by-step explanation:
-4z=20
divide both sides of the equation by -4
-4z/-4=20/-4
z=-5
