d=8.1
1.2+d+0.4=9.7
Add 0.4 and 1.2
1.6+d=9.7
-1.6 -1.6
Subtract 1.6 from both sides
d=8.1
Answer:
y=mx+b
10=15x+B
b is whatever the number is you got to add or multiply to get the next number
Step-by-step explanation:
Answer:
no proportional.if it was proportional it would start at (0,0)
Using a system of equations, it is found that the total amount of money the two ladies spent was of $782.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
- Variable x: Amount Mrs. Smith had initially.
- Variable y: Amount Mrs. Wilson had initially.
Mrs smith had $46 more than Mr.s Wilson at first, hence:
x = y + 46.
Mrs Wilson spent 4/7 of her money on some clothes and, and Mrs. Smith spent 3/5 of her on household items, then they remained with an equal amount, so:
Since x = y + 46, we have that:
14(y + 46) = 15y
y = 14 x 46
y = $644
x = 644 + 46 = $690
Hence the amount they spent is given as follows:
