Answer: the solution is 1
Step-by-step explanation:
you subtract the 8 from 9 so you can get the variable, y, by itself.
Answer:
$82 sundaes
$74 banana split
Step-by-step explanation:
Step one :
Given data
Cost of sundaes =$2 each
Cost of banana split =$3 each
Let the number of sundaes bought be x
And the number of banana split bought be y
The total is x+y
The shop sold 8 more Sundaes than the Banana split
x=8+y—-------1
Total amount made = $156
Therefore the system of equation for the situation is
x=8+y----—----------1
2x+3y=156---------2
But x=8+y
8+y+y=156
8+2y=156
2y=156-8
2y=148
Divide both sides by 2
y=148/2
y=74
On That day they sold $74 banana split
And also they sold x=8+74=$82 sundaes
Answer:
Solving the inequality
we get 
Option D is correct option.
Step-by-step explanation:
We need to solve the inequality
and find value of x
Solving the inequality for finding value of x, we will keep x on left side of inequality and all other terms on the right side.

Adding 2 on both sides

Now, we will divide 3 on both sides

So, we get x < 2
Solving the inequality
we get 
Option D is correct option.
Answer:

Step-by-step explanation:
Given
Shape: Rectangle
Diagonals: AC and BD

Required
Determine BD
From the question, we understand that the shape is a rectangle and its diagonals are AC and BD
Every rectangle has 2 diagonals, both of which are equal.
This implies that:

Recall that:

Hence,
