A percentage can be converted to a decimal. 30% -> 0.30.

Now multiply 60x0.30, which is 18.

So 18 were wearing sweatshirts. But that's not what we need.

Subtract 60-18, which is 42.

42 were not wearing sweatshirts.

The number of students who attended Albany Medical College last year was 1000. This year, attendance has increased to 1350 stude

NeTakaya

First you have to subtract 1350-1000 to get 350. Then you have to make 350/1000 into a percent. First you have to turn it into a decimal. In the fraction 350/1000 can be reduced to 35/100. In decimal form it would be 0.35. In pecentage form it would be 35%. The percentage difference of the student population would be 35%.

4-(2x-3)=3 whats the answer

Oxana [17]

Hello there.

Explanation:

↓↓↓↓↓↓↓↓↓↓

$4-(2x-3)=3$

First, subtract by 4 from both sides.

$4-(2x-3)-4=3-4$

Second, simplify.

$-(2x-3)=-1$

Third, divide by -1 from both sides.

$\frac{-(2x-3)}{-1}=\frac{-1}{-1}$

Fourth, simplify.

$2x-3=1$

Next, add by 3 from both sides.

$2x-3+3=1+3$

Then simplify.

$2x=4$

Therefore, divide by 2 from both sides.

$\frac{2x}{2}=\frac{4}{2}$

Finally, simplify.

$x=2$

<u><em>Answer⇒⇒⇒⇒x=2</em></u>

Hope this helps!

[*Please Help me with this Question, Thank you & Please!*]

Answer:

x=3

Step-by-step explanation:

Since both triangles are similiar, this means they can have different sized sides, but they are just scaled versions of each other. This also means that no matter what sides they have, their angles are going to be the exact same

Knowing this, it helps to draw them out side by side so you can match them up easier. Both of them have a 90 degree angle, and more specifically they are 45-45-90 triangles (45-45-90 is a special right triangle). You can point this out since they give us a 90 degree angle and two angles that are congruent in the same triangle. In order for that to work, they HAVE to be 45-45-90

With this, we can find out what x equals. Since the two angles markings line up with the two side angles in the other triangle, we know that they are equal to each other.

we can use the equation 15x = 45, since 45 is what the side angle should equal.

now, we just divide 45 by 15, and we should get 3

so x = 3!

I hope this helps :)
