They must conform with Pythagoras theorem
It is set 4 because
(sqrt 2)^2 + (sqrt 7)^2 = 3^2
2 + 7 = 9
Answer:
Simplify 2x - 4) + 7(x + 2).
9x + 6
9x - 4
09x - 6
= 9x+10
Answer:
X = V/(YZ)
Step-by-step explanation:
V=XYZ
Division property of equality
V/(YZ) = X
Symmetric property of equality
X= V/(YZ)
Answer:
190%
Step-by-step explanation:
$1.56 is close to nearly 2x the value of $0.87
You can start by multiplying $0.87 by 2 to get $1.74
Now put $1.56 / $1.74
This gets you 0.89655172
By rounding this, you can get to 0.90
Move the decimal places two spots over to get a percentage = 90%
Since the eggs didn't decrease in value, you can add the 100% from the beginning of the problem.
100+90=190%

Answer:</h3>

<h3>
Step-by-step explanation:</h3>
In this question, we're trying to find how much Hermione spent on plums.
We know that:
- Hermione bought 9/10 of a pound of plums
- Plums cost $1.30 <em>per pound</em>
With the information above, we can solve the question.
Since we know that plums cost $1.30 per pound and Hermione bought 9/10 of a pound, we would multiply 1.30 by 0.90 in order to get the price Hermione bought the plums for. Hermione is pretty much paying 90% of the cost of a pound.

When you multiply, you should get 1.17
This means that Hermione spent $1.17 on 9/10 pound of plums.
