7x + 17 = 7x - 17
7x + 17 - 7x = 7x - 17 - 7x
17 = -17
Inconsistent: for no value of x is the above equation true. 17 ≠ -17.
Hope this helps! :)
Answer:
19
Step-by-step explanation:
you would choose a number that you can easily subtract 5 from. You should always take care of whats in the () first.
Selling price of app per user = $10 per month
Total no. of user in first month = 10
To tal no. of user added per month = 7
We have to find how much money is earned in one year
So the formula is n/2 * (2a +(n-1)d)
Here we have n = 12 which is total no. of months
a = 100 , which is money earned in one month
d = 70 , which is increase in money earned per month
So money earned in a year comes out to be 5820
Answer:
1. A = 40 units²
2. A = 72 units²
3. B) 45
Step-by-step explanation:
1. This shape comprises 4 congruent triangles with base of 5 units and height of 5 units.
Area of a triangle = 1/2 x base x height
Therefore, area of polygon = 4(1/2 x 5 x 4)
= 40 units²
2. This shape comprises two pairs of congruent triangles.
Area of a triangle = 1/2 x base x height
Therefore, area of polygon = 2(1/2 x 2 x 6) + 2(1/2 x 10 x 6)
= 72 units²
3. Count the number of shaded squares:
9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 45 units²
Answer:
$3.80
Step-by-step explanation:
$4.35+$3.10+$1.45+$1.45+$0.85=$11.20
$15.00-$11.20=$3.80
