Tori bought 24 candy bars for 69 cents each. She used partial products to find the total cost in cents. Which are NOT possible p
rewona [7]

Answer:

B. 36 C. 180 D. 240 E. 1,656

Step-by-step explanation:

Partial product is the multiplication of individual digit of a number in turn with each digit of the others where each digit maintains its place.

Using distributive property to multiply 24 × 69 to determine our partial products:

i.e.

24 × 69 = 24 × (60 + 9)

= (24 × 60) + (24 × 9)

= 60 (20 + 4) + 9(20 + 4)

So; we can have:

= (60 × 20) + (60 × 4) + (9 × 20) + (9 × 4)

= 1200 + 240 + 180 + 36  

= 1656

Four times a number added to 3 times a larger number is 31. Seven subtracted from the larger number is equal to twice the smalle
notka56 [123]

Answer:

Let x represent the smaller number and y represent the larger number

<u>For the first equation </u>

Four times a number added to 3 times a larger number is 31 is written as

4x + 3y = 31

Making y the subject we have

3y = - 4x + 31

Divide both sides by 3

That's

y =  -  \frac{4}{3} x +  \frac{31}{3}

<u>For the second equation</u>

Seven subtracted from the larger number is equal to twice the smaller number is written as

y - 7 = 2x

Making y the subject

We have

<h3>y = 2x + 7</h3>

Hope this helps you
