Answer:
3 gulps
Step-by-step explanation:
In this problem, f(x) = 3. Plug this into the equation:
3 = -3x + 12
Solve for x:
3 - 12 = -3x + 12 - 12
-9 = -3x
-9 / -3 = -3x / -3
3 = x
3 gulps
Answer:
Step-by-step explanation:
25x - 35 = 5*5*x - 5*7
= 5*( 5x - 7)
Perimeter = 2L + 2w
in this case, L = 3w - 2 and perimeter = 28.
so, 28 = 2L + 2w. or 14 = L + w. or substitute for L: (3w - 2) +w =14
or 4w - 2 = 14. 4w = 12. 12/4 = 3 = w.
The width = 3 inches; and the length = (3x3 -2) 7 inches.
Answer:
Proportions and ratios are extremely important when administering medication. Many doses are determined by weight, and ratios are how those medications are often displayed.
Answer:
No, 2.171m.
Step-by-step explanation:
Add all of measurements. 3.52+17.3+27.009=47.829
Compare 2 numbers.
47.829<50
So she needs more ribbon,because the length she has is less the requirement, 50m.
Find the difference(the length she needs).
50-47.829=2.171
