Answer:
y = 25 + 40x
Step-by-step explanation:
Let
y = the total amount of money Justin has
x = number of weeks
Amount Justin has in the bank = $25
Amount Justin earns per week = $40
Equation for how much money Justin has (including the amount he has in the bank) in x weeks
the total amount of money Justin has = Amount Justin has in the bank + (Amount Justin earns per week * number of weeks)
y = 25 + (40 * x)
y = 25 + 40x
The equation is
y = 25 + 40x
Step-by-step explanation:
w = 3(2a + b) - 4
w = 6a + 3b - 4
6a = w - 3b + 4
a = 1/6 * (w - 3b + 4).
Answer: 1/7
Step-by-step explanation:
26+6+10=42
6/42=1/7
A. 11/30 x 50= 18/36=1/2
18/36 x 1/10= 5/100
B. 1,210 x 1.1= 1,331
I am not so sure about A, but I hope this helps a little.
Answer:
7/30
Step-by-step explanation:
We are given that Seven-ninths (7/9) of the pencils in a box are yellow and three-tenths (3/10) of the yellow pencils are sharpened.
To find the fraction that represents sharpened yellow pencils, we find the product of the the fraction of yellow pencils and the fraction of yellow pencils that are sharpened.
That is:
=> (7 / 9) * (3 / 10)
=(7 * 3) / (9 * 10)
= 21 / 90
= 7 / 30
7/30 represents the fraction of sharpened yellow pencils.
