He needs 6 more hot dog buns. You just simply subtract 12 from 18.
Answer:
1/81
Step-by-step explanation:
In h(x)=3^x, replace each instance of x with -4:
h(-4) = 3^(-4), or
1
h(-4) = ----------- = 1/81
3^4
Answer:
Notebooks: $2.75 each; pens: $1.10 each
Step-by-step explanation:
Let n and p represent the unit cost of notebooks and the unit cost of pens.
Then 3n + 2p = $10.45, and 4n + 6p = $17.60.
Let's use elimination by addition/subtraction to find n and p.
Multiplying the first equation by -3, we get -9n - 6p = -$31.35
and then combine this with the second: 4n + 6p = $17.60
-----------------------------
Then, -5n = -$13.75
Dividing both sides by 55, we get n = $13.75 / 5, so we now know that n = $2.75. Each notebook costs $2.75.
Subbing $2.75 for n in the first equation, we get:
3($2.75) + 2p = $10.45, or
$8.25 + 2p = $10.45
Solving for p, we get p = $2.20 / 2 = $1.10.
Each pen costs $1.10.
Answer:
7(6+y)=(7×6)+(7×y)
Because the 7 will multiply the 6 and also multiply the y and you will get that answer
Answer:
He makes 24,000 a year
Step-by-step explanation:
First figure out how much he makes a month without the extra $50 every day he works. which is $600, then add the 4 weeks (28 days) worth of the $50 every day, which is $1400, then add the $600 to get $2000 a month, then times that by twelve, which is $24,000.
