Step-by-step explanation:
The variables w, x, and z are not needed because this expression only contain one variable, y
y= 5 It says it in the problem
Start by substituting the value of y into the expression
y+5 = 5+5
Solve
5+5 = 10
Solution: y+5 = 10

Step-by-step explanation:
Formula for SA of a rectangular prism:
SA = 2lh + 2lw + 2wh
Given dimensions:
l = 1
w = 7
h = 6
Simply plug in these given dimensions into the SA formula to get the answer
SA = 2lh + 2lw + 2wh
Substitute given variables
SA = 2(1)(6) + 2(7)(1) + 2(6)(7)
* Multiply parentheses that are next to each other *
SA = 2(6) + 2(7) + 2(42)
* Multiply again *
SA = 12 + 14 + 84
*add*
SA = 110

Answer:
Total number of points in the test = 100
Total number of items in the test = 40
Let number of items of 2 points be x and number of items of 3 points be y.
Now, using the given information the situation can be represented by using the following equations :
⇒ x + y = 40 .........(1)
⇒ 2x + 3y = 100 .........(2)
The matrix equation is :
By solving the equation (1) and equation (2), we get :
Solution : x = 20 and y = 20
The total number of cups in the package is 2300.
<h3>What is Percentage?</h3>
Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100.
Here,
Let the total number of cups in the package be x.
Number of green cup = 690
Weightage of green cup in total = 30%
Now,
30% of x = 690
30/100 X x = 690
x = 690 X 100/30
x = 23 X 100
x = 2300
Thus, the total number of cups in the package is 2300.
