Step-by-step explanation:
In this case, you input the value of y (y = 6) into the equation ( 2.5(y-x)= 0)
2.5(6-x) = 0
Open the bracket,
(2.5×6)-2.5x= 0
Collect like terms.
2.5x= 2.5×6
Divide both sides by the coefficient of x (2.5)
x = 6
So,
x= 6 is true.
.
Substituting 6 for x in the equation,
2.5(6-6)= 0
2.5•0 = 0
0= 0
Which is also true.
Answer:
You just need to substitute 4 in for h.
So 48 + 25(4) = 48 + 100 = 148
So this is our inequality in algebraic terms: 
Firstly, subtract n on both sides of the inequality: 
Next, subtract 5 on both sides of the inequality, and <u>your inequality is 
</u>
By moving the decimal point two spaces to the left, the number becomes a number between one and ten
the answer is 6.56 times 10^2
