Answer:
12 gallons
Step-by-step explanation:
Since this is a return journey then total distance = 2 × 216 = 432 miles
Dividing the distance by 36 gives gallons required
number of gallons = = 12
The correct answer is C)
.
Since it is a geometric sequence, we multiply by a constant, r, each time to find the next term.
g₂ = -8
g₅ = 512
g₂ * r * r * r = g₅
-8(r)(r)(r) = 512
-8r³ = 512
Divide both sides by -8:
-8r³/-8 = 512/-8
r³ = -64
Take the cubed root of both sides:
∛r³ = ∛-64
r = -4
Now we work backward from g₂ to find g₁:
-8/-4 = 2
We have that g₁ = 2 and r = -4. This gives us
Answer:
○ 6
○
Step-by-step explanation:
Let <em>c</em><em> </em>represent<em> </em>three-pound bags and <em>a</em><em> </em>represent one-pound bags.
Use a system of equations:
{9 = c + a
{36 = 5c + 2a
−⅕[36 = 5c + 2a]
{9 = c + a
{−7⅕ = −c - ⅖a >> New Equation
____________
1⅘ = ⅗a
__ ___
⅗ ⅗
[Plug this back into both equations above to get the c-term of 6];
