When x=5 ,
5(x+2) - 4 = 5(5+2) - 4 = 5(7) - 4 = 35 - 4 = <em>31</em>
Step-by-step explanation:
Given that,
a + 2b = 17
Also,
2a + b = 4
By adding the above expressions we get,
a + 2b + 2a + b = 17 + 4
3a + 3b = 21.
3 (a + b) = 21
a + b = 21/3
a + b = 7 Let us take 'b' = 10
a + 10 = 7
a = 7 - 10
a = -3
Now let's check by verifying by putting a = -3 and b = 10 in the previous expressions
a + 2b = 17
-3 + (2 × 10) = 17
-3 + 20 = 17
17 = 17
2a + b = 4
(2 × -3) + 10 = 4
-6 + 10 = 4
4 = 4
Therefore, a = -3 and b = 10 [(-3,10)] is the solution.
Answer:
x/8
Step-by-step explanation:
First, we are given "the quotient of...". This means that we are dividing something/something else. If two numbers are given in the phrase "something and something else", the first number given will be the something, and the second number will be the something else.
The first number listed is x. Therefore, we have
x/something else.
Next, we are given "and 8", so we have x/8 as our expression
Answer:
5 percent or 5.7349percent
divide 43209 by 45687 and get 1.0573491 subtract one
and get 0.0573491 make into a percentage 5.7percent depending on where you need to round.
1/4 because there is 2 LR ads and 6 other ads, making a total of 8 and 2/8 simplifies to 1/4. Hope this helped!
