16 - 2t = 5t + 9<br><br> What number does t represent? I'm bored

seraphim [82]

Try not to be bored. You can take the attitude that you actually like math, and that you will some day actually be a MathGenius.

t represents an unknown quantity defined by the equation 16 - 2t = 5t + 9.

To find this value, do the following: Add 2t to both sides, and then subtract 9 from both sides. You'll end up with 7t = 7, which yields t = 1.

We call this the "solution" of the equation given.

Which of the division expressions below has a remainder? Select all that apply.

gavmur [86]

Answer:

A, B, C, & E

Step-by-step explanation:

A) 19,456 ÷ 6 = 3,242 $\frac{2}{3}$

(2/3 is 0.666666666 etc)

B) 28,765 ÷ 13 = 2,212.692308...

C) 4,145 ÷ 3 = 1,381 $\frac{2}{3}$

(2/3 is 0.666666666 etc)

D) 4,165 ÷ 17 = 245

(Not bolded because it is not an answer)

E) 44,312 ÷ 16 = 2,769.5

C -> When dividing by three, if the first number's values do not add up to a multiple of 3 there will be a remainder. Example from your problem,

4,145 -> 4 + 1 + 4 + 5 = 14 -> 14 is not a multiple of 3, so there is a reminder

D -> No decimal / fraction, no remainder!

Have a nice day!

I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

Lenora buys 3.7 pounds of potatoes that cost $0.29 per pound and 4.8 pounds of onions that cost $1.23 per pound. How much does L

Likurg_2 [28]

Given:

Cost per pound of potatoes is $0.29.

Cost per pound of onions is $1.23.

To Find:

The total amount Lenora spent on potatoes and onions.

Answer:

<h2>Lenora pays 6 dollars and about 98 cents in all.</h2>

Step-by-step explanation:

The per pound price of potatoes is $0.29.

Lenora buys 3.7 pounds of potatoes.

To calculate the cost of the potatoes she bought, we must multiply the per pound rate with the total weight of potatoes she bought.

So, the cost of Lenora's potatoes is $(0.29)(3.7) = $1.073

Next, the per pound rate of onions is $1.23.

Lenora buys 4.8 pounds of onions.

To calculate the cost of the onions she bought, we must multiply the per pound rate with the total weight of onions she bought.

So, the cost of Lenora's onions is $(1.23)(4.8) = $5.904

To find the toal cost, we add the price she paid for the potatoes and onions which is $1.073 + $5.904 = $6.977.

<h2>This means Lenora pays 6 dollars and about 98 cents in all.</h2>
