Answer: the cost of one shirt is $28
the cost of one sweater is $23
Step-by-step explanation:
Let x represent the cost of one shirt.
Let y represent the cost of one sweater.
Lonnie purchased three sweaters and two shirts for $130. It means that
2x + 3y = 130 - - - - - - - - -1
If the sale price of a shirt was five dollars less than the sale price of a sweater, it means that
x = y - 5
Substituting x = y - 5 into equation 1, it becomes
2(y - 5) + 3y = 130
2y - 10 + 3y = 130
2y + 3y = 130 + 10
5y = 140
y = 140/5
y = 28
x = y - 5 = 28 - 5
x = 23
It is in standard form: y=mx+b
You divide 18.40 by 2.3 to find out how many dollars per hour. 18.40/2.3=8.
Ellie earned $8.00 per hour.
Two, 2 and 7, because 3/11 just equals 0.2727272727..., so the two and seven keep repeating
If you would like to order the following numbers from least to greatest, you can do this using the following steps:
<span>- 40, 1250, - 6.44, 0.2
</span>- 40 < - 6.44 < 0.2 < 1250
The correct result would be <span>- 40 < - 6.44 < 0.2 < 1250.</span>
