Answer:
471
Step-by-step explanation:
do to the number in the tenths place not being higher than 5 all number past the decimal become zero and the whole number stay the same
Let us say that:
x = cost of shorts
y = cost of slacks
z = cost of sports coat
From the given statements, we can create the following
equations:
eqtn 1: 3 x + y =
10.96
eqtn 2: 7 x + 2 y +
z = 30.40
eqtn 3: 4 x + z =
14.45
Rewrite eqtn 1 explicit to y:
y = 10.96 – 3 x -->
eqtn 4
Rewrite eqtn 3 explicit to z:
z = 14.45 – 4x -->
eqtn 5
Plug in the values of y (eqtn 4) and z (eqtn 5) to eqtn
2:
7 x + 2 (10.96 – 3 x) + 14.45 – 4 x = 30.40
7 x + 21.92 – 6 x + 14.45 – 4 x = 30.40
- 3 x + 36.37 = 30.40
- 3 x = - 5.97
x = 1.99
Eqtn 4:
y = 10.96 – 3 x
y = 10.96 – 3 (1.99)
y = 4.99
Eqtn 5:
z = 14.45 – 4x
z = 14.45 – 4 (1.99)
z = 6.49
Therefore each shirt cost $1.99, each slacks cost $4.99,
and each sports coat cost $6.49.

A+(-1.3)=-4.5
Add 1.3 to both sides of the equation
a=-3.2
The equation given in the question should be written down first and then the process should start for solving and finding the value of the unknown variable "x".
6x + 8 = 2x + 11
6x - 2x = 11 - 8
4x = 3
x = 3/4
The value of the unknown variable "x" comes out to be 3/4. I hope the procedure for solving this equation is clear enough for you to understand. In future you can always use this procedure to get to the solution of similar problems.
