2B Multiplied by 3 plus B = 7B. Here is how it's worked out. You start with 2B, multiply that by 3 and you get 6B. Now all you have to do is add the last B, therefore adding 1B to equal 7B.
It is an equation and the value of b is 3
Pre-caculus 1 - Pre-Algebra 2 - Algebra I 3 - Geometry 4 - Algebra II 5 - Pre-Calculus 6 - Calculus
Yes there is an algebra 3, but some schools don't have it and they just go to Pre-Calculus.
My Teacher said in the begining of pre calculus it is baisically algebra 3 and geometry 2. pre calc algebra is more complicated than basic algebra. however pre calc uses that basic algebra in solving problems. so all in all, they are just different levels of algebra
7b-10 = -3
For the function G defined by G(x)=5x+3, find G(2b).
a = Larger numberb = Smaller numbera - 17 = 7b ... (1)a - 132 = 2b ... (2)Rearrange (2)a = 2b + 132 (3)Substitute (3) into (1)2b + 132 - 17 = 7b(Take 2b from both sides)132 - 17 = 5b5b = 115b = 23Substitute b = 23 into (2)a - 132 = 2 x 23a - 132 = 46a = 46 + 132a = 178
Sometimes you can think of things instead of letters, for example...3a + 2a = ?If that was 3 apples plus 2 apples equals ... ? then you could do it, right?3 apples + 2 apples = 5 apples3a + 2a = 5aAnd the same with MINUS...10b - 7b = ?10 bananas - 7 bananas = 3 bananas10b - 7b = 3bOf course, you can't add bananas and apples, you have to count them separately, so...3a + 4b + 7a - 2b= 3 apples + 4 bananas + 7 apples - 2 banana= 10 apples + 2 bananas= 10a +2b(You can't add these two together)After that it gets more complicated...
