The distributive property combines (blank) and (blank) to make multiplying whole numbers simpler.
emmasim [6.3K]
I am not too sure whether there were options, but one way to approach this is to fill it with "multiplication" and "addition" - the distributive property combines addition and multiplication to make multiplying whole numbers simpler. The gain is that you don't have to make one difficult multiplication, but a couple of simpler ones and then you can add them up.

Two planes just took off from Charlotte NC. The first plane is traveling 1.5 times as fast as the second plane. After traveling
Ksju [112]

Givens

Slower plane

r = r

t = 2.5 hours

d = d

Faster Plane

r_faster = 1.5 * r

t = 2.5 hours

d1 = d + 127.5

The  time is the same for both

t = d/r

d1/r1 = d/r

(d+ 127.5)/1.5r = d/r   Multiply each side by r

(d + 127.5)/1.5 = d       Multiply both sides by 1.5

d + 127.5 = 1.5d          Subtract d from both sides.

127.5 = 1.5d - d    

127.5 = 0.5d              Divide by 0.5

127.5 / 0.5 = d

255 = d

Now you can go back and figure out the rates.

First find d1

d1 = d + 127.5

d1 = 255 + 127.5

d1 = 382.5

<em><u>Rate of the slower plane</u></em>

d = 255

t = 2.5 hours

r = d/t

r = 255/2.5

r = 102 miles per hour.

<em><u>Faster plane</u></em>

d1 = 382.5 miles

t = 2.5 hours

r1 = d/t

r1 = 382.5/2.5 = 153 miles per hour.

The product of 1 1/2 and 2 is
Over [174]

Method 1:

Convert the mixed number to the improper fraction:

1\dfrac{1}{2}=\dfrac{1\cdot2+1}{2}=\dfrac{3}{2}

Make the product:

1\dfrac{1}{2}\cdot2=\dfrac{3}{2}\cdot2

<em>canceled 2</em>

=\dfrac{3}{\not2_1}\cdot\not2^1}=\boxed{3}

Method 2:

1\dfrac{1}{2}=1+\dfrac{1}{2}

1\dfrac{1}{2}\cdot2=\left(1+\dfrac{1}{2}\right)\cdot2

<em>use the distributive property a(b + c) = ab + ac</em>

(1)(2)+\left(\dfrac{1}{2}\right)(2)=2+1=\boxed{3}

antoniya [11.8K]

Cevap:

Salı

Adım adım açıklama:

İlk depozito (Pazartesi) = 8 lira

Günlük yatırılan miktar = 3 lira

74 liraya sahip olmak için gereken gün sayısı;

Gün sayısı = x olsun

8 + 3x = 74

3x = 74 - 8

3x = 66

x = 66 / 3

x = 22 gün

Pazartesiden 22 gün sonra; Salı gününe denk gelecek
