Answer:
x = 2 and y = 
Step-by-step explanation:
To solve this system of equation, we will follow the steps below;
We will use both elimination and substitution method to solve this system of equations
12x−15y=14 ------------------------------------------------------------------------(1)
8x−15y=6 --------------------------------------------------------------------------(2)
subtract equation (2) from equation (1)
(By doing that the y variable will be eliminated)
4x = 8
Divide both-side of the equation by 4
4x/4 = 8/4
x = 2
Substitute x =2 into equation (2) and then solve for y
8x−15y=6
8(2)−15y=6
16 - 15y = 6
subtract 16 from both-side of the equation
16 - 16- 15y = 6-16
-15y = -10
Divide both-side of the equation by -15
-15y/-15 = -10/-15
y = 
x = 2 and y = 
Formula for P: P = 2W + 2L
Formula for A: A = WL
Here, P = 2(4 ft) + 2(7 ft) = (8+14) ft = 22 ft
and A = (4 ft)(7 ft) = 28 ft^2
20 pounds beacuse you have to first divide the ton by pounds
Answer:
2.5 is less than 1,950.
Step-by-step explanation:
The decimal place is at the end of 1,950.
The decimal place is in the middle of the 2 and the 5.
Since 2.5 decimal place is closer, that means 2.5 has a lower value than 1,950.0.
You can subtract both values.
1,950 - 2.5 = 1,947.50, if it’s greater than 0, it means it has a lower value.
0 < 1,947.50.
Therefore, 2.5 < 1,950
Answer:
3 foot 3 inches
Step-by-step explanation:
How much deeper the hole should be = intended depth - current depth
Convert feet to inches for easy calculation
1 ft = 12 inch
5 x 12 = 60 inches
1 foot = 12
12 + 9 = 21 inches
60 - 21 = 39 inches
convert inches to feet
39 /12 = 3 feet 3 inches
