Step-by-step explanation:
this is how you solve it :)
Answer:
8
Step-by-step explanation:
x=pizza
y= breadsticks
3x+2y=30
2x+3y=25
first we myltiply the top equation with 3 and then w emultiply the lower equation with -2 so it is
9x+6y=90
-4x-6y= -50
now we can add them together and the y contracts
5x=40
now we divide it by 5
x=8
So pizza costs 8
Answer:
3/4 of a 6-ounce glass will be drunk by her in one hour.
Step-by-step explanation:
Given time = 2/3 of hour
= 2/3 (60) As hour = 60 mins
= 120/3
= 40 mins
Given quantity of water = 1/2 of 6-ounce
= 3 ounce
So,
In 40 mins, water intake is 3 ounce
In 1 min, water intake is 3/40
In 60 mins, water in take is (3/40)*60 = 4.5 ounce
Quantity of water intake in 60 mins:
4.5 ounce or 3/4 of 6-ounce glass
I hope it will help you.
we know that
A number is an inequality solution if the number satisfies the inequality
<u>Part 1)</u> 
rewrite the inequality

The answer Part 1) is the option D 
Because
satisfies the inequality
-----> is true
<u>Part 2)</u> 
The answer Part 2) is the option A 
Because
satisfies the inequality
-----> is true
<u>Part 3)</u> 
we're going to verify every case
<u>case A)</u> For 
substitute the value of x in the inequality

------> is true
therefore
The number
is a solution
<u>case B)</u> For 
substitute the value of x in the inequality

------> is not true
therefore
The number
is not a solution
<u>case C)</u> For 
substitute the value of x in the inequality

------> is not true
therefore
The number
is not a solution
<u>case D)</u> For 
substitute the value of x in the inequality

------> is not true
therefore
The number
is not a solution
therefore
The answer Part 3) is the option A
