Answer:
p = -2
Step-by-step explanation:
O we have to solve this equation:
24p + 12 - 18p = 10 + 2p - 6
First, we will operate what we have in both sides:
24p - 18p + 12 = 10 - 6 + 2p
6p + 12 = 4 + 2p
We substract 2p in both sides and 12 too.
6p + 12 - 2p - 12 = 4 + 2p - 2p - 12
4p = -8
Now, we divide both sides by 4
4p/4 = -8/4
<span>-3a+7b=-16
-9a+5b=16
multiply 1st equation by 3
</span><span>-9a + 21b = -48
-9a + 5b =16
------------------------subtract
16b = -64
b = - 4
</span>-3a+7b=-16
-3a+7(-4)=-16
-3a = -16 +28
-3a = 12
a = -4
answer
a. first choice
<span>The values of a and b are both equal to –4.</span>

Answer:
6/5 or 1 and 1/5
Step-by-step explanation:
To do this you need to multiply 6/1, 2/3, and 3/10 all together by cancelling out the numerator in 3/10 and the denominator for 2/3. Then you would be left with 6*2*1/10
This simplifies to 6*1/5 because of the 2*1/10 is 1/5, because 1/5 doubled is 1/10.
then multiply the numerator and 6 together to get 6/5.
Hope this helps!
Answer:
More than 8 seconds
Step-by-step explanation:
Xandler
- Has water = 15.4 oz
- Decrease rate = 0.5 oz/sec
Leon
- Has water = 5.4 oz
- Addition rate = 0.75 oz/sec
Time = x
<u>Inequality for the required condition is:</u>
- 15.4 - 0.5x < 5.4 + 0.75x
- 10 < 1.25x
- x > 10/1.25
- x > 8 seconds
