Start by distributing the 7 to both terms on the left hand side, and the 5 to both terms on the right hand side.
7(x - 2) = 5(x + 4)
7x - 14 = 5x + 20
Now, to solve for x, start by isolating the variable as much as you can.
7x - 5x = 20 + 14
2x = 34
x = 17
Answer with Step-by-step explanation:
Let a and b are two integers.
We have to show that
if 3\a+b then 3\a-b is false.
In order to prove that given statement is false we prove this with the help of example
Suppose we have two integers a=2 and b=4
if 3\2+4
3\6=2
2-4=-2
But 3 does not divide -2.
Therefore, the given statement is false.
Hence, proved.
Answer:
1: -7
2: -7
3:-7
4: 8
5: 8
6: 8
Step-by-step explanation:
for the first one, you do 6-1=5 and then times that by 2 and then simplify that to get -7. for the second one, you do
which is 8+4=12, and divide 24 by that to get 2 and minus nine to get -7. for the 3rd one, you do
+9 first (16+9)= 25, and subtract 39 from that to get 14, then do 4-5=-1 *2=-2, which gets you -7. for 4 , you do 81-25= 56 over 10+8-11=7 which gets you 8. for 5, you do 36-20=16 in parentheses first and then divide 48 by that to get 3 and subtract that to get 8. last, for 6, you do 22-14 to get you 8
Answer: 4500 grams
Step-by-step explanation: 1 kilogram is 1,000 grams, so 4 kilograms is 4,000 grams, and half a kilogram is 500 grams. So, 4000 + 500 = 4,500
Answer:
Step-by-step explanation:
y-5=3(x+2)
y-5=3x+6
y-5-6=3x+6-6
y-1=3x
