Answer:
56
Step-by-step explanation:
to find the answer, divide 42 by 6/8
42 x 8/6 = 56
Our missing number we are solving for is X.
We are told x will equal 2x (number doubled) plus -16.
x = 2x + -16 We want to move the smaller variable to the right to sit with the larger one and move the -16 to the left by subtracting it from both sides. Remember that subtracting a negative is the same as adding it. So essentially we add 16 to both sides.
16 = 2x - x Combine the variables
16 = x or x = 16
I chose to put the variable on the left in this problem to avoid having a -x on the left side. It doesn't matter which side the variable is on to solve, but when you state it - we usually say x = 16.
Answer: D. 2.8 - 0.6t
Step-by-step explanation:
The t represents how much time it takes. So, it goes down by 0.6 per second until it gets to 0.
1/3p+1/3x9=3+2p-12
1/3p+3=-9+2p
1/3p-2p=-9-3
1/3p-2p=-12
Now we put all the number under the common denominator 3 and we multiple -2p and -12 by 3
And this equals to:
1p-6p=-36
-5p=-36/x(-1)
5p=36
P=36/5
