Just work this problem out backwards. First write out an equation.
(x+4)•3=30
Now solve :
(x+4)•3=30
3x+12=30
-12 -12
3x=18
/3 /3
x=6
Your answer is 6!
Hoped I helped!
Answer:
x=-3.5
Step-by-step explanation:
-3x=10.5 divide both sides by -3
Answer:
sorry sir i really dont even understand
The answer to an absolute value must be positive
here are examples of simple ones
ex1:|-5|=5
ex2:|-3|=3
<span>ex3:</span>|3|=3
Answer:
I believe you're supposed to solve for the other missing side. If you know a side (a) and the diagonal or also known as the hypotenuse (c), you will be able to solve for the other side using the Pythagorean theorem.
Step-by-step explanation:
a^2+b^2=c^2 Substitute the values for a and c
24^2+b^2=30^2 Solve for the powers
576+b^2=900 Subtract 576 from both sides
b^2=324 Solve for the root of 324
18=b
You would need 18 inches of material to cover one side of the suitcase.
