500.3333333333333−−−−−−−−−−−−−−−√≈22.368132093076824
Step-by-step explanation:
two sides of length =0.6 and 1.6
lengths for the third side,X =?
= 0.6+1.6=2.2
lengths for the third side of X=2.2
Hence, the equation for the question (7) is
and equation for (8) is
. It can be solved by linear equation in one variable.
What is a linear equation in one variable?
A linear equation in one variable is written as
. Here,
and
are constants and
is a variable.
(7)
Consider n number of baseball cards does Mike have. Since this is 19 less then the cards Allan have hence, as you add 19 in n then it will give 84.
(8)
Consider the speed of Michelle is n. As, it is 3 times less than the speed of the Jamie hence, it you multiply 3 with n then it will give 12.

Hence, the equation for the question (7) is
and equation for (8) is
.
