Step-by-step explanation:
<u>Evaluate Expressions</u>
An algebraic expression consists of a set of variables and constants related by algebraic operations like addition, subtraction, multiplication, etc.
To evaluate an algebraic expression, we replace the variables for the constant value they are assigned.
Let's consider the expression:

for x=10, y=-1, z=0
Substituting the variables for their values:



The value of the expression is 11
Answer:
£10
Step-by-step explanation:
3:1
difference in the ratio is 2 so 2 is £20
so 1 is 20/2 =10
Sushil is 1 in the ratio an 1 x 10 is 10.
this is a brief explanation.
Hope this helps x
Their common factors are :1, 2 ,5 ,10
7(x + 2) = 6(x + 5)
7x + 14 = 6x + 30 |subtract 14 from both sides
7x = 6x + 16 |subtract 6x from both sides
x = 16
