Answer:
<h2>
3x = 18</h2>
Step-by-step explanation:
Use the Pythagorean Theorem here:
30² = (3x)² + (4x)², or:
30² = 9x² + 16x² = 25x²
Taking the square root of both sides, we get √(30)² = √(25x²), or:
30 = ± 5x
Neglect -5x, since we are measuring distances, and distances are positive.
Then 5x = 30, and so x = 6
Thus, 3x = 3(6) = 18

Does the question tell you how many sandwitches and cookies a basket can hold?
Answer:
a=3, c=-4, x=8
Step-by-step explanation:
5=4a-7
4a-7=5
4a=5+7
=12
a=12÷4
=3
3-8c=35
-8c=35-3
=32
c=-32÷8
=-4
-1/2x-7=-11
-1/2x=-11+7
=-4
x=4÷1/2
=4/1×2/1
=8
