15(90-3)
first way
15 times 90 = 135
15 times 3 = 45
135 - 45 = 90
second way
90-3 = 87
15(87) = 1305

Explain how to use the distributive property to solve 48 divided by 3
KonstantinChe [14]

We have to divide 48 by 3 using distributive property.

Division using distributive property is used as it is much easier and accurate.

For dividing 48 by 3, we split first 48 as a multiple of 3 and 10

i.e. 48 = 30+18

Now divide again 18 as 3x5 +3

i.e. 48 = 30+15+3

By distributive property we have 48/3 = (30+15+3)/3 =30/3 +15/3 +3/3

Now easier to calclate this

30/3 = 10 : 15/3 =5 and 3/3 =1

Hence 48/3 = 10+5+1=16

Glados works as a nurse at a county hospital in Baton Rouge. Glados
Serga [27]

Answer:

Glados makes $44.76 per hour.

Step-by-step explanation:

Given:

Total hours Glados worked this week = 38.4

Amount earned by Glados this week = $1,718.64

To find her hourly earnings for the week.

Solution:

We will use unitary method to find the unit rate.

If for 38.4 hours Galdos earned = $1,718.64

Then for 1 hour she will earn = \frac{\$1,718.64}{38.4}=\$44.756\approx\$44.76

Thus, Galdos' hourly earnings for the week = $44.76

nirvana33 [79]
Use the Pythagorean theorem for this. (a^2+b^2=c^2)

a=9, b=12, c=x

9^2+12^2=c^2
81 + 144 = c^2
225 = c^2
c =15 

the answer is c

lisov135 [29]

Answer:

4x/y¹¹

Step-by-step explanation:

1) take out constants

40/10 * x⁻⁴y⁻⁶/x⁻⁵y⁵

2) simplify 40/10 to 4

4 * x⁻⁴y⁻⁶/x⁻⁵y⁵

3) Use Quotient Rule: xᵃ/xᵇ=xᵃ⁻ᵇ

4x⁻⁴⁺⁵y⁻⁶⁻⁵

4) Simplify -4 + 5 to 1

4x¹y⁻⁶⁻⁵

5) simplify -6-5 to -11

4x¹y⁻¹¹

6) use rule of one: ₓ¹=ₓ

4xy⁻¹¹

7) use negative power rule: x⁻ᵃ=1/xᵃ

4x * 1/y¹¹

8) simplify

4x/y¹¹
