eight more than twice a number is less than twenty (what is the expression)
2x+8 <20
We have the following:
solving for x
The solution of x is equal to 28, therefore 12 is not a solution of the equation
Answer:
BD
Step-by-step explanation:
to find the longest segment in a triangle, first find the largest angle and the line opposite to it is the largest segment:
in this case it is angle BCD and the segment opposite is BD
Answer:
C
Step-by-step explanation:
point-slope equation is y-y1=m(x-x1)
y1=2
x1=6
m=(-5/7)
so the equation is y-2=-5/7(x-6)
hope this helps :3
The shopkeeper spends 2x + 21 dollars on electricity
The amount the shopkeeper spends on electricity less than $100 is:
x < 39.5
<h3>What is a linear inequality?</h3>
Linear inequality explains the range of values that a variable represents.
Total amount spent by the shopkeeper = 7x + 19
Amount spent on rent = 5x - 2
Total amount spent = Amount spent on rent + Amount spent on electricity
(7x + 19) = (5x - 2 ) + Amount spent on electricity
Amount spent on electricity = (7x + 19) - (5x - 2)
Amount spent on electricity = 7x - 5x + 19 + 2
Amount spent on electricity = 2x + 21
For which value(s) of x is the amount the shopkeeper spends on electricity less than $100?
Amount spent on electricity < 100
2x + 21 < 100
2x < 100 - 21
2x < 79
x < 79/2
x < 39.5
