Answer:
You could use Math-way to help.
It asks you what kind of answer you want.
Step-by-step explanation:
You first put in the equation then you tell them you want it to be answered by long division. Then you'll get the answer.
Answer:
top left is your bet
Step-by-step explanation:
Y = 5x - 1...so we sub 5x - 1 in for y in the other equation
-15x - 3y = 3
-15x - 3(5x - 1) = 3
-15x - 15x + 3 = 3
-30x = 3 - 3
-30x = 0
x = 0
y = 5x - 1
y = 5(0) - 1
y = -1
it has one solution (0,-1) <=
If five mechanical pencils cost #4.27.
we need to find the scale factor used to calculate the cost of 54 pencils
We are given with 5 pencils
We need to find the scale factor for 54 pencils
we need to find out what multiply with 5 to get 54
For that we divide 54 by 5
so scale factor is 10.8
5 times 10.8 = 54
We multiply the scale factor 10.8 by cost of 5 pencils to find the cost of 54 pencils
10.8 * 4.27 = 46.116 = $46.12
the scale factor 10.8 is used to calculate the cost of 54 pencils
