Answer: she bought 13 petunias
Step-by-step explanation:
Let x represent the number of Petunias pot of flowers that she bought.
Let y represent the number of begonias pot of flowers that she bought.
She bought 22 potted plants. This means that
x + y = 22
Petunias cost $7 per pot and begonias cost $8 per pot. She spent a total of $163. This means that
7x + 8y = 163 - - - - - - - - - - - -1
Substituting x = 22 - y into equation 1, it becomes
7(22 - y) + 8y = 163
154 - 7y + 8y = 163
- 7y + 8y = 163 - 154
y = 9
x = 22 - y = 22 - 9
x = 13
The relative order of the metric prefixes is micro-, milli-, centi- and kilo-,
<h3>What are metric units?</h3>
Metric units are units used to measure quantities
The units are given as:
kilo-, micro-, centi-, and milli-
In metric units, the value of each prefix is:
Kilo = 1000
Micro = 0.0001
Centi = 100
Milli = 0.1
In order of arrangement, we have:
Micro = 0.0001
Milli = 0.1
Centi = 100
Kilo = 1000
Hence, the relative order of the metric prefixes is micro-, milli-, centi- and kilo-,

First 4/7 times 7/11 and plus 5,the result of 4/7 times 7/11 equal 4/11,AND THEN 4/11 PLUS 5 EQUAL 5 AND 4/11
Answer:
127
Step-by-step explanation:
400+1495=1895
1895/15=126.333333333
CosA=(21^2+23^2-25^2)/2*21*23
cosA=345/966
A=cos^-1(345/966)
A=69.08
