Already you can see that -y and y will make a zero
add both together
3x=21
x=7
plug x in
7+y=5
y=-2
Answer:
180
Step-by-step explanation:
10% of 300=30
30*6= 180 (to get 60 percent you multiply 10% by 6)

<span>Hey there, Lets solve this together.
</span>
<span>The variable (R) will be representing the rate as a decimal.
When you solve for (R) multiply by 100 to get the percentage. A percentage is </span><span>a rate, number, or amount in each hundred.
</span><span>"0.97" will be replaced by "(97/100)"
</span>
<span>Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the given equation
</span>
Rewrite the whole as a fraction using 10 <span> as the denominator :
</span>
The equation now takes the shape :
t • (10f-291)<span> = 0
</span>
<span><span> f = 291/10 = 29.100
</span> t = 0</span>
<span>Positive = Growth
Negative = Decay
</span><span>

Answer:
32 free throws.
Step-by-step explanation:
It is given that,
Peter shot 40 free throws. He made 80% of his shots.
We need to find the fraction that is equivalent to 80%.
It means we have to find 80% of 40. It can be calculated as follows :

80% of 40 is equivalent to 32 free throws.
You are calculating the perimeter of the triangle.
Just add up the 3 side lengths. It's 20.6 meters.
