Your answer would be c<em>= b- d/a</em>

First you have to distribute a, so multiply a times both b and c.

a(b-c)=d

ab-ac=d add ac to both sides

ab=d+ac subtract d from both sides

ab-d=ac divide a into both sides

$\frac{ab-d}{a}$ =c

The answer is A: c = $\frac{ab-d}{a}$

Bob and Maria each purchase steak from the butcher. Maria selects a cut that costs $19.98 per pound. Bob’s selection costs $13.9

Sidana [21]

Answer:

Bob is paying more for the actual steak

Step-by-step explanation:

we know that

Maria selects a cut that costs $19.98 per pound (Maria's steak is all meat)

Bob’s selection costs $13.98 per pound (Bob’s cut of beef is 1⁄3 bone and fat)

Bob's cut is 2/3 all meat

Find the unit rate of Bob's cut for all meat

$\frac{13.98}{(2/3)} \frac{\$}{pounds} =20.97\frac{\$}{pounds}$

therefore

$\$20.97> \$19.98$

Bob is paying more for the actual steak

0.5x+7/3 = 21/4 cross multiply

TiliK225 [7]

Solving the expression $\frac{0.5x+7}{3}=\frac{21}{4}$ we get: $x=\frac{35}{2}\,\,or\,\,x=17.5$

Step-by-step explanation:

Solving the expression: $\frac{0.5x+7}{3}=\frac{21}{4}$

Solving by cross multiplying:

$\frac{0.5x+7}{3}=\frac{21}{4}\\(0.5x+7)*4=21*3\\Simplifying:\\2x+28=63\\Adding\,\,-28\,\,on\,\,both\,\,sides:\\2x+28-28=63-28\\2x=35\\Divide\,\,both\,\,sides\,\,by\,\,2\\\frac{2x}{2}=\frac{35}{2}\\x=\frac{35}{2}\,\,or\,\,x=17.5$

So, solving the expression $\frac{0.5x+7}{3}=\frac{21}{4}$ we get: $x=\frac{35}{2}\,\,or\,\,x=17.5$
