Answer:
There area 14 one cent stamps
Step-by-step explanation:
Let
x -----> the number of 1 cent stamps
y -----> the number of 8 cent stamps
z -----> the number of 12 cent stamps
we know that
0.01x+0.08y+0.12z=1.78 -------> equation A
x=y+4 ------> y=x-4 -----> equation B
x=2z -----> z=0.5x ------> equation C
substitute equation B and equation C in equation A and solve for x
0.01x+0.08(x-4)+0.12(0.5x)=1.78
0.01x+0.08x-0.32+0.06x=1.78
0.15x=1.78 +0.32
0.15x=2.10
x=14
therefore
There area 14 one cent stamps
In y = mx + b...the slope is in the m position and the y intercept is in the b position.
y = -7x - 2
slope(m) = -7
y int (b) = -2...or (0,-2)
Answer:
15.89
Step-by-step explanation:
You would divide 149 by 9 and get 15.88.However this 8 will keep repeating so you have to round it up.

Answer: 6.00 + 3.60x
Step-by-step explanation:
Regular coffee= 2.00 each
Letters= 3.50 each
Samantha buys 3 regular coffees and x letters.
To get the total amount she spends at the coffee shop, we multiply each quantity bought by the price. Therefore, total amount will be:
= (2.00×3) + (3.50×x)
= 6.00 + 3.50x
The expression for the amount spent at the coffee shop is 6.00+3.50x
