Family drinks 1 3/4 gallons of milk every 4 1/2 days what is the unit rate of milk per day
natita [175]
\bf \cfrac{milk}{day}\qquad \cfrac{1\frac{3}{4}}{4\frac{1}{2}}\implies \cfrac{\frac{1\cdot 4+3}{4}}{\frac{4\cdot 2+1}2}\implies \cfrac{\quad \frac{7}{4}\quad }{\frac{9}{2}}\implies \cfrac{7}{\underline{4}}\cdot \cfrac{\underline{2}}{9}\implies \cfrac{7}{2}\cdot \cfrac{1}{9}\implies \cfrac{7}{18}

which gives us a quotient of about 0.39 gallons of milk for one day.<span />

Michael just became a personal trainer and is finalizing his pricing plans. One plan is to charge $36 for the initial consultati
nexus9112 [7]

The cost will be same for one session. The cost will be $128.

Step-by-step explanation:

Given,

Initial consultation charges for Plan One = $36

Per session fee = $92

Let,

x be the number of sessions.

O(x) = 92x+36

Initial consultation charges for Plan Two = $86

Per session fee = $42

T(x) = 42x+86

For same cost;

O(x) = T(x)

92x+36=42x+86\\92x-42x=86-36\\50x=50

Dividing both sides by 50

\frac{50x}{50}=\frac{50}{50}\\x=1

Putting x=1 in T(x)

T(1)=42(1)+86\\T(1)=42+86\\T(1)=128\\

Putting x=1 in O(x)

O(x) = 92(1)+36\\O(x) = 92+36\\O(x) = 128

The cost will be same for one session. The cost will be $128.

Burka [1]

Answer:

\huge\boxed{-2i+4j}

Step-by-step explanation:

u=-5i+2j\\\\v=-6i+4j\\\\-2u+2v=-2(-5i+2j)+2(-6i+4j)\\\\\text{use the distributive property}\\\\=(-2)(-5i)+(-2)(2j)+(2)(-6i)+(2)(4j)\\\\=10i-4j-12i+8j\\\\\text{combine like terms}\\\\=(10i-12i)+(-4j+8j)\\\\=-2i+4j
