6-8. Always do brackets first!
1. 208/x = 100/130
2. multiply both sides by x
3. 208 = 0.76923x
4. divide both sides by 0.76923
5. x = 270.4
Answer:
16
Step-by-step explanation:
Let's call the liters x. We can write 0.15x + 0.4 * 4 = 0.2 (x + 4). When we solve for x we get x = 16 liters.
Answer:
x = 17
Step-by-step explanation:
The angles are congruent.
So, set them equal to each other.
______
2x - 12 = 22
Apply inverse operations
[+12] 2x - 12 = 22 [+12]
2x = 34
x = 17

Answer y= 16/99
Explanation:
the initial statement is
y ∝ 1/x
To convert to an equation multiply by k the constant of variation
⇒ y = k × 1/x = k/x
To find k use the given condition y = 15 when x = 5
y = k/ x
⇒ k = y*x = 8 * 2 =16
equation is
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
y = 16/ x
when
x = 99
then
y = 16/99
Y = 16/99
