Answer:
434 sweatshirts were sold
Step-by-step explanation:
$2,170/$5 = 434
All you do is solve for z. So 8z-13=7. To solve for a variable you have to do the opposite to cancel out the numbers on each side. First you add 13 over to 7 to cancel out 13 on the z side. So 8z=20 is what you have left. Then you divide 8 on both sides to cancel out 8 on the z side. what you are left with is z=2.5. Lastly you plug and check. 8(2.5) - 13 = 7, 20-13=7. And thats correct so z is 2.5.
Answer:
hypotenuse = 5
height = 2
Using Pythagoras theorem,
5² = 2² + m²
=> 25 = 4 + m²
=> 25–4 = m²
=> √21 = m
=> m = 4.58
Value of m is 4.58
The given expression is
We just have to divide by 2
<h2>Hence, the solution is all real numbers less than 10.</h2>
