2*2*4+2*2*24+2*4*24
16+96+192=304
304 is the answer
Answer:
y = -15
x = -10
Step-by-step explanation:
1/4x - 1/2 = 5 (1)
3x + 2/3y = -40 (2)
Multiply (1) by 4
1/4x - 1/2 = 5
1/4x * 4 - 1/2y * 4 = 5 * 4
4/4x - 4/2y = 20
x - 2y = 20 (3)
Multiply (2) by 3
3x + 2/3y = -40 (2)
3x * 3 + 2/3y * 3 = -40 * 3
9x + 6/3y = -120
9x + 2y = -120 (4)
x - 2y = 20 (3)
9x + 2y = -120 (4)
Using elimination method, Add (3) and (4)
9x + x = -120 + 20
10x = -100
x = -100/10
x = -10
Substitute x = -10 into (3)
x - 2y = 20 (3)
-10 - 2y = 20
-2y = 20 + 10
-2y = 30
y = 30/-2
y = -15
y = -15
x = -10
You are able to divide or mutiply both so let's divide. Divide each by four to get1/2. hope this helped.
Answer:
652
Step-by-step explanation:
Just add the numbers to together. It is already separated into hundreds, tens and ones, so just place them in the correct columns.
Here is another one of those " quadratic word problems " at hand, which is great!
By the function that is given to us ( which I believe is meant to be 
) the airplane is launched at a height of 251 metres, with no velocity. Anyhow, we need to determine the duration with which the airplane will strike the ground, and to do so we can set up the following equation, 
- solving for t, otherwise known to be the time!
See the procedure below -
- Subtract 251 from either side,
- Divide either side by - 5,
- And, now isolate t, receiving two solutions,
However, time can't be a negative value. Thus our solution is 
, which is ( about ) 7.085 seconds!
