Step-by-step explanation:
Use the Pythagorean theorem:
We have
Substitute:
<em>subtract 16 from both sides</em>
Substitute:
If y = 2x, then y/x = 2. The constant of proportionality is 2.
Answer:
$18
Step-by-step explanation:
5% of $15 = $0.75
15% of $15 = $2.25
$2.25 + $0.75 =$3 + $15 (price of the meal before tax/tip is applied)
$3+$15=$18
Answer:
0.6t - 4.3s -2.6
Step-by-step explanation:
Given the expression
(-3.5t - 4s + 4.5) + (-7.1 - 0.3s + 4.1t)
Collect the like terms
= -3.5t+4.1t-4s-0.3s+4.5-7.1
= 0.6t - 4.3s -2.6
Hence the required expression is 0.6t - 4.3s -2.6
