Answer:
The system would be:
4x + 2y = 140
2x + 3y = 150
Step-by-step explanation:
If we represent the cost of sweats by the letter x and the jeans by the letter y, we can then write an equation for each of the situations using the number of each in each situation.
4x + 2y = 140
2x + 3y = 150
Y= 1/2x plus three
This works for all of the ordered pairs so will most likely be correct
Answer:
(x+12)(x-15)
Step-by-step explanation:
They are both decimals.
But 0.04 > 0.004.
Answer:
They are all true
Step-by-step explanation:
1. 3² +4² = 5²
3x3 + 4x4 = 5x5
9 + 16 = 25
25 = 25
-----------------------
2. 6² + 8² = 10²
36 + 64 = 100
100 = 100
------------------
3. 9² + 12² = 15²
81 + 144 = 225
225 = 225
-------------------
4. 5² +12² =13²
25 + 144 = 169
169 =169
-------------------
