fractions:
Fraction is a part of a whole, for example 1/2. Equivalent fractions are fractions that look different but show the same amount. Improper fractions have numerators that are higher than the denominator, while mixed fractions contain whole numbers and fractions.
In order to compare fractions, you need to change them so they have the same denominator. Fractions can be converted into decimals. You need to be able to work out a fraction of a given quantity.

How do we find 3/5 of 20?
Method 1 is to find 1/5 of 20, then multiply by 3.
1/5 of 20 is 20 ÷ 5 = 4.
We need 3/5 of 20, so we multiply 4 by 3.
3/5 of 20 = 4 × 3 = 12.
you can put this in your calculator:
3/5<span> × 20 = </span>3/5<span> × </span>20/1<span> = </span>60/5<span> = 12</span>
It is 50 degrees.
Since you already know two are 90 and 40 add them together and you get 130.
A triangle has 180 degrees so minus 130 from that
180-130=50

Hey there! Welcome to Brainly! I'm happy to help you!
Let's quickly write our equation below.
4(1-x)+2x=-3(x+1)
To solve this, we want to get the x by itself on one side of the equation so we can see what it equals on the other side. First, we need to get it out of the parentheses. To do this, we will use the <em><u>distributive property </u></em>and multiply the number before the parentheses by both terms inside of it as seen below! :)
4(1)-4(x)+2x=-3(x)-3(1)
4-4x+2x=-3x-3
Now, we need to combine our like terms.
4-2x=-3x-3
Now, we want to get all of our constants (numbers without variables) onto the right side. First, we will subtract four from both sides.
-2x=-3x-7
Now, we will add 3x to both sides.
x= -7
I hope that this helps! Have a wonderful day!
Answer:
550 N
Step-by-step explanation:
We can solve the problem by using Newton's second law:
F is the force required to accelerate the car
m is the mass of the car
a is the acceleration of the car
In this problem, the mass is m=1100 kg, while the acceleration is a=0.5 m/s^2, therefore the force required to accelerate the car is
Hope this helps!
