Answer:
Given:
x-y=-4
2x+y=4
Step-by-step explanation:
x-y=-4
2x+y=4
add both the equation, we get
⇒ x-y=-4
2x+y=4
⇒3x=-4+4
⇒3x=0
⇒x=0
∴ to find the value of y, put the value of x in any one equation
⇒x-y=-4
⇒0-y=-4
⇒-y=-4
⇒y=4
∴ x=0, y=4
Answer:
Step-by-step explanation:
Area of box = 14^2 = 196 in^2
Radius r of pizza = 12/2 = 6
Area of pizza = πr² = 36π ≈ 113.04 in^2
712/8=?
First found out what 71/8 is. 71/8 is 8 and 7/8. This tells that there is 7 left so now you add 7 to two which gives you 72. Then you divide 72/8=9 and combine 8 and 9 which gives you 89. So 712/8=89
Answer:
9:20 am
Step-by-step explanation:
So, lets go over two things.
Minutes and hours.
Minutes changes the second number.
You know how when a number goes from 9 to 10 how the ones place is set to 0, and the tens place goes up? Its the same with time, only when the number goes from 59 to 60, the hour goes up.
Hours changes the hours place, and when it hits 12, it resets to 1, and the words am go to pm, or pm goes to am.
In this case. we are moving the minutes place up by 5:
15+5=20
So the minutes place is 20, and does not change the hours place since it is below 60.
Next we have a increase in hours by 2:
8+1=9
So the hours place is 9, and does not reset or change the pm/am since its below 12.
Answer:
9:20am
Hope thias helps!
