Answer:
x = 5 pens
y = 7 pencils
Step-by-step explanation:
let
x = the number of pens
y = the number of pencils
Anthony spent $2.80 to buy a total of 12 pens and pencils
0.35x + 0.15y = 2.80
x + y = 12
by solving the system of equations
0.35x + 0.15y = 2.80
x + y = 12
we find
x = 5 pens
y = 7 pencils
Answer:
7
Step-by-step explanation:
BW is 1/3 of the way of JB
like the other question we set up an equation
2x+1=10x+1 but because BW is only one third of the way we have to multiply its side by 3 and the new equation is
9x+3=10x+1
step 1: subtract each side by 9x
3=x+1
step 2; subtract each side by 1
2=x
Next we plug in 2 to x in 3x+1 and get a final answer of
BW = 7
