M + t + w = 19
t = 2m
w = 2m - 6
now we sub
m + (2m) + (2m - 6) = 19...combine like terms
5m - 6 = 19
5m = 19 + 6
5m = 25
m = 25/5
m = 5 <== she sold 5 books on Monday
t = 2m......t = 2(5)...t = 10 <== she sold 10 books on Tuesday
w = 2m - 6....w = 2(5) - 6....w = 10 - 6...w = 4 <== she sold 4 books on Wednesday.
<span>25 w to the sixth power over 10 w to the third power divided by 30 w squared over 5 w.
25w</span>⁶ / 10w³ ÷ 30w² / 5w
Get the reciprocal of the 2nd fraction and multiply it with the 1st fraction
25w⁶ / 10w³ * 5w / 30w² → 25w⁶ * 5w / 10w³ * 30w² = 125w⁷ / 300w⁵
*When you multiply exponents with the same base, you simply add them.
w⁶ * w = w⁶⁺¹ = w⁷
w³ * w² = w³⁺² = w⁵
Cancel out w⁵
<span>125w⁷ / 300w5 </span>= 125w² / 300
Simplify the constant:
125 / 25 = 5
300 / 25 = 12
5w² / 12 is the simplified form of the given equation.
Answer:
200
Step-by-step explanation:
Given that :
16% of coins are quarters from 1990
Number of quarters from 1990 = 32
Since 16% = 32 quarters
The number of the total coins can be obtained thus :
Let the total number of coins = x
16% = 32
100% = x
Cross multiply :
0.16x = 32 * 1
0.16x = 32
x = 32 / 0.16
x = 200
Hence, total number of coins in the collection = 200
You would do 13/52 times 1/52
Answer:
13 units
given two points: (−3, −8) and (10, −8)
As the y coordinates are same.
use the method:
|x2| + |x1| where (x1, y1), (x2, y2)
Solve:
|10| + |-3|
10 + 3
