Answer:
No
Step-by-step explanation:
The variables are different in both problems. In 2×+7=27, it's 10, while in the other problem, it's 9.
27 doesn't equal 28.
You will need to use the Pythagorean Theorem, actually a derivative of it sometimes called the "distance formula" to find the length of the segments between two points. Mathematically the distance is:
d^2=(x2-x1)^2+(y2-y1)^2
d=√(dx)^2+(dy)^2)
Answer:
C. $11.55
Step-by-step explanation:
First, multiply 4 by $0.85 to get an answer of $3.40. Next, multiply 6 by $1.25 to get an answer of $7.50. Add up the cost of the pencils and pens by adding $3.40 and $7.50 to get $10.90. Next, we have to add the tax. Multiply $10.90 by 0.06 to get $.65. Add the $.65 to the $10.90 for a grand total of $11.55. Hope this helps!
Answer:
x > -3
Step-by-step explanation:
Step 1: Write inequality
-5x + 6 < 21
Step 2: Solve for <em>x</em>
- Subtract 6 on both sides: -5x < 15
- Divide both sides by -5: x > -3
