Answer:

x=2, y= 21

Step-by-step explanation:

y = 6x + 9

y = 7x + 7

Since both equations are equal to y, we can set them equal to each other

6x+9 = 7x+7

Subtract 6x from each side

6x+9-6x = 7x -6x+7

9 = x+7

Subtract 7 from each side

9-7 = x+7-7

x=2

Now we need to find y

y = 6x+9

y = 6(2) +9

y = 12 +9

y = 21

\bf \cfrac{\frac{13}{6}}{\frac{x}{1}}=\cfrac{2}{5}\cdot \cfrac{1}{1}\implies \cfrac{13}{6}\cdot \cfrac{1}{x}=\cfrac{2}{5}\implies \cfrac{13}{6x}=\cfrac{2}{5}\implies 13\cdot 5=2\cdot 6x
\\\\\\
65=12x\implies \cfrac{65}{12}=x\implies \boxed{5\frac{5}{12}=x}
\\\\\\
\cfrac{5\cdot 12+5}{12}\implies \cfrac{65}{12}

Mom buys a rectangular rug with an area of 7 1/6 square meters. The length of the rug is 3 1/3 meters. What is the width of the
BartSMP [9]

Answer:

  • 2 3/20 m

Step-by-step explanation:

The area is the product of the length and width

  • The area = 7 1/6 m² = 43/6 m²
  • The length = 3 1/3 m = 10/3 m

Width = ?

  • A = lw
  • w = A/l
  • w = 43/6 ÷ 10/3 = 43/6 × 3/10 = 43/20 = 2 3/20 m

The width is 2 3/20 m

Lori bought some cookies for $2 each and muffins for $3 each. She bought twice as
Lubov Fominskaja [6]

Answer:

2 cookies

Step-by-step explanation:

let c represent cookies, m represent muffins. set up a system of equations:

2c+3m=16

m=2c

(the top equation shows that cookies are $2 each, and muffins are $3, and that the total cost is $16. the bottom equation shows that Lori bought twice as many muffins as cookies).

then solve the system of equations by substitution, substituting 2c for m in the top equation:

2c+3(2c)=16

2c+6c=16

8c=16

c=2

this means that lori bought 2 cookies.
