Y = x + 3
2x + y = 9

substitute the first equation into the second equation;
2x + y = 9
2x + x + 3 = 9
3x + 3 = 9

solve for x;
3x + 3 = 9
3x = 9 - 3
3x = 6
x = 2

solve for y, given the value of x;
y = x + 3
y = 2 + 3
y = 5

so the answer is (2, 5).

hope this helps, God bless!

svlad2 [7]

Quantity of cheerios cereal in the smaller box Hannaford sold = 9 ounces

Cost of nine ounces of cheerios cereal = $2.50

Cost of one ounce of cheerios cereal :

$= 2.50 \: \div \: 9$

$=\color{plum}\$ 0.27$

Cost of one ounce of cheerios cereal in the smaller box = $0.27

Quantity of cheerios cereal in the larger box Hannaford sold = 20 ounces

Cost of nine ounces of cheerios cereal = $3.79

Cost of one ounce of cheerios cereal :

$= 3.79 \div 20$

$=\color{plum} \$0.18$

Cost of one ounce of cheerios cereal in the larger box = $0.18

Difference in their cost per ounce :

$= 0.27 - 0.18$

$=\color{plum}\bold{\$ 0.09}$

Therefore, the difference in cost in dollars per ounce between the two sizes = $0.09

A baseball player got 61 hits one season. He got h of the hits in one game. What expression represents the number of hits he got

mina [271]

Answer:

$(61-h)$

Step-by-step explanation:

Total number of hits by baseball player in one season = 61

Number of hits in one game = $h$

To find:

The expression to represent the number of hits that the player got in the rest of the games = ?

Solution:

Number of hits that the player got in one game = $h$

Let the number of hits that the player got in rest of the games = $x$

As per the given question statement,

The sum of $h$ and $x$ will be equal to 61.

$h+x=61\\\Rightarrow \bold{x =61-h}$

Therefore, the player had $(61-h)$ hits in the rest of the games.
