Answer:
3x +4y = 118
5x+6y =180
y= $25
Step-by-step explanation:
Let x = the cost of a flashlight
Let y = the cost of a sleeping bag
3x +4y = 118
5x+6y =180
Multiply the first equation by -5
-5(3x +4y) = -5*118
-15x -20y = -590
Multiply the second equation by 3
3(5x+6y) =3*180
15x + 18y = 540
Add the modified equations together.
We are using elimination to eliminate the variable x
-15x -20y = -590
15x + 18y = 540
----------------------------
-2y = -50
Divide by -2
-2y/-2 = -50/-2
y =25
Each sleeping bag costs $25
first divide 90 by 4 to see how many words per minute
90 ÷ 4 = 22.5
then multiply 22.5 by 10 to get your answer
so your answer is;
225 words per 10 minutes
Answer:
$17.70
Step-by-step explanation:
Hi,
What you want to do is to find 30% of $59
First, you convert 30% into decimal form by dividing it by 100
30%=0.3
Next, you want to find 30% of 59, so what you do is you take the new decimal form and multiply it by 59
0.3×59=17.7
