Step-by-step explanation:
Answer:
9 magazines
Step-by-step explanation:
To solve this problem you will want to work backwards. Start with the junk mail. There is 18 junk mail and if there are 1/3 as many bills as junk mail then you will need to multiply 18 * 1/3. This equals 6 bills. If there is twice as many bills as letters then you will need to divide bills(6) by 2 which equals 3. If there are 6 more magazines than letters then you need to add 6 to the letters (3). 3 + 6 = 9
The clothes weigh 14.77 kilograms.
Given:
Weight of suitcase = 50 pounds
Towels = 20% of weight
Shoes = 15% of weight
Clothes = 65% of weight
convert pounds to kilograms using proportion:
<u>pounds</u> <u>2.2</u> = <u>50</u>
kilograms 1 x
2.2x = 50 ⇒ x = 50/2.2 ⇒ x = 22.73 kgs
Clothes : 22.73 kgs * 65% = 14.77 kgs
Towels : 22.73 kgs * 20% = 4.55 kgs
Shoes : 22.73 kgs * 15% = 3.41 kgs
Answer:
<em>The answer is 0</em>
<em>So I think no solutions</em>
Step-by-step explanation:
You gotta get each equation into slope-intercept form, nd when u do that 9x - 3y = 6 turns into y = 3x - 2, nd 5y = 15x + 10 turns into y = 3x + 2. Add the equations together, nd get 0.
