Answer:
1. Exponents- e.is the number of times the BASE NUMBER is multiplied by itself.
2. Term- a.is a number by itself or the product of a number and variable (or more than one variable).
3. Variables- d.letters or symbols used in place of a quantity we do not know yet.
4. Coefficient- c.the number in front of a variable
5. Constant- b.is a number that stays fixed in an expression
Step-by-step explanation:
J = jeans
T = t-shirts
You: 5j + 10t = 140
Friend: 3j + 5t = 79
To use elimination in this problem, multiply the second equation by -2 so that 10t and 5t can cancel out:
5j + 10t = 140
-6j - 10t = -158
We are left with -j = -18 or j = 18
Substitute 18 into any equation. I'll use the first equation:
5(18) + 10t = 140
90 + 10t = 140
10t = 50
t = 5
