Answer:
x≥4.5
x is all number greater than or equal to 4.5
Step-by-step explanation:
2x≥5+4
2x≥9
x≥9/2
x≥4.5
x is all number greater than or equal to 4.5
Given:
The given statement are:
a. Eight less than the product of seven and x.
b. The sum of six and the product of three and d.
To find:
The expression for the given statements.
Solution:
a.
Product of 7 and x is 7×x = 7x.
Eight less than the product of seven and x is 7x - 8.
Therefore, the required expression for the statement "Eight less than the product of seven and x" is 7x-8.
b.
Product of 3 and d is 3×d = 3d.
The sum of six and the product of three and d is 6+3d.
Therefore, the required expression for the statement "The sum of six and the product of three and d" is 6+3d.
Answer:
Step-by-step explanation:
x²+10=9
x²=9-10
x²=-1=i²
x=±i
Using proportions, it is found that she runs 3.106855 miles in one week.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
Researching this problem on the internet, it is found that the measurement is in meters, and we want to find the number of miles. She runs 5,000 meters. Each meter has 0.000621371 miles, hence the number of miles that she runs is given by:
M = 5000 x 0.000621371 = 3.106855 miles .
Maria runs 3.106855 miles in one week.
