Dr. Hoover, a pediatrician, has 3 annual checkups and 2 sick visits scheduled next Tuesday,

Jet001 [13]

Dr. Hoover allot his time on Tuesday for an annual checkup is 147 minutes and for a sick visit is 42 minutes (Total 189 minutes)

On Wednesday appointment, he allot his time for an annual checkup is 147 minutes and for a sick visit is 21 minutes (Total 168 minutes)

solution

Let us assume, minutes for annual checkup denoted as x and

minutes for sick visit denoted as y

The equation of Tuesday visit is $3x + 2y = 189 minutes ------ 1$

The equation of Wednesday visit is $3x + 1y = 168 minutes ------ 2$

by changing the signs of the equation 2 and subtract it from the equation 1 we will get 1y = 21 minutes

to substitute y =1 in the equation 2 we get

$3x + 2(21) = 189$

$3x + 42 = 189$

$3x = 189 - 42$

$3x = 147$

$x = 147 ÷ 3 = 49 minutes$

then now we have substitute both x = 49 and y= 21 in equation ----- 2

we will prove that $3x + 2y = 189 = 3 (49) + 2(21) = 189$ $147+ 42 = 189 minutes$

so the Tuesday appointment , the time allotted for an annual checkup is 147 minutes and for a sick visit is 42 minutes (Total 189 minutes)

On Wednesday appointment, the time allotted for an annual checkup is 147 minutes and for a sick visit is 21 minutes (Total 168 minutes)

Eamon wants to buy a new baseball glove that costs $50. he has $14 and earns $6 per hour cleaning yards. How many hours must he

konstantin123 [22]

Answer:

The answer is that he would have to work 6 hours to have enough money to buy the glove.

Step-by-step explanation:

1: Find the amount he needs to earn by subtracting $14 from $50: 50 - 14 = 36. So he needs to earn $36.00.

2: Since you have to find the amount of hours, you can divide $6 from $36 to get the amount of hours he needs to work: 36 / 6 = 6. Eamon only gets $6.00 per hour so he would have to work 6 hours to get the $36.00.
