To solve for x in an inequality is very similar to solving for x in an equation since for both you would need to isolate x.
step 1) -2x-4>8 add the 4 over to move any constants over to the +4 +4 other side.
-2x> 12
step 2) x< -6 Divide out the -2 to isolate x, however, keep in mind, when you divide or multiply over any negative number, you must also remember to flip the inquality sign.
Answer: x<-6
Answer:
4D - 1
Step-by-step explanation:
So, if Ted saves $D for 4 weeks, then this amount will be equal to 4D because multiplication is simply repeated addition. We can imagine this situation as D+D+D+D, for the 4 weeks he is saving. We can simplify this to 4D in the expression.
Next, the question tells us that this will be 1 dollar more than needed. So, if we want to find the cost, we need to subtract that dollar.
Thus, the final expression is 4D - 1 because this represents 1 dollar less than the money he saves for 4 weeks.
Answer:
h
Step-by-step explanation:
y=-x-5. you just need to add 1 to another side to get rid of 1 from the left side
Answer:
x=80
Step-by-step explanation:
im going to assume this is perimeter.
50+50=100
260-100=160
160÷2=80
