Find the value of 3x+6 given that -2x-8= 8

1 answer:

8 0

-18 because when you solve -2x-8=8 you get that x=-8 (plus 8 on both sides, then divide by -2 to isolate x) and then if you plug -8 in with 3, you get -24 then add the 6 which is -18.

What is the inequality shown

CaHeK987 [17]

Answer:

We can also graph inequalities on the number line. The following graph represents the inequality x≤2 . The dark line represents all the numbers that satisfy x≤2 . If we pick any number on the dark line and plug it in for x, the inequality will be true.

Marrrta [24]

Alright, lets get started.

Maria hiked the 5 mile Mountain Trail a number of times and she hiked the 10 mile canal trail several times.

x times she hiked 5 mile mountain.

So, number of mils she hiked for 5 miles will be = 5 x

Similarly,

y times she hiked 10 mile canal,

So, number of miles she hiked for canal = 10 y

So, total number of miles she hiked = $5 x +10 y$

But as per question given, she had a total of 90 miles

It means

$5x + 10 y = 90$

Dividing this equation with 5

$x + 2 y = 18$

So, the equation is $x + 2 y = 18$ : Answer

Hope it will help :)

What’s different about solving inequalities when you have to multiply or divide by a negative number? Can you explain why a spec

Sergeu [11.5K]

Alright, let's take an example. 1 is less than 2, so we can write it as 1<2. However, if we multiplied both sides by -1 without changing anything else, we get -1<-2, but -1 is greater than -2 because it is less negative, so the correct way of writing it would be -1>-2. Therefore, since a number that is less positive than another becomes less negative (and therefore higher) when both are multiplied by -1, we have to change the side of the inequality
