Step-by-step explanation: look so if you have
shcool A its 8v+4b=12
and
School B: 12v+4b= 16
since both classes used 4 busses we can use elimination by subtracting the A class Equation from the b class equation to solve from v for its value Then, use either equation and the now found value for v to solve for b.
You should find part of the process to be
12v+4b-(8v+4b)=12-16 which shows the van holds only a few people even before continuing the solution.
Answer -4
Answer:
10.5
Step-by-step explanation:
Break the problem down into small parts:
2 to the power of 3= 8
8+7+6=
15+6=21
21/2
21 divided by 2 is 10.5
Hope this helps!
Answer:

Step-by-step explanation:
i'm guessing u must be from UK.... in the US "standard form" is known as "Scientific Notation"
Write 3.25 x 10^4 as an ordinary number: 32 500
Write 6.04 x 10^-3 as an ordinary number: 0.00604
Write 2 400 000 in standard form : 2.4 x 10^6
Write 0.00147 in standard form: 1.47 X 10^-3
The resulting expression on factorization by grouping method is (3-7x²)(x-3).
<h3>What is Factorization?</h3>
Factorization is a method in which an Integer or an expression is written in terms of product of its fractions.
The expression given in the question is
–7x³ + 21x² + 3x – 9
This equation has to be factorized using grouping method.
group of two or more is formed and common term is taken out.
-7x² (x -3) +3(x-3)
( -7x²+3) (x-3)
(3-7x²)(x-3)
The resulting expression on factorization by grouping method is
(3-7x²)(x-3).
