Answer:
No Solution.
Given Equations:
- 3x + y = 15 ....[Equation 1]
- y = -3x + 8 ....[Equation 2]
Substitute Equation 2 into 1
No solution, as L.H.S ≠ R.H.S
Answer:
4. 30 inches
5. 76.2 cm
6. 1024 sqaure inches
Step-by-step explanation:
4. √900 = 30 (area of a square = s²)
5. 30*2.54 = 76.2 cm
6. Each side is 2 inches longer ⇒ 30+2 = 32 inches (each side length)
area of a square = s²
32² = 1024 square inches
Answer:
14/19
Step-by-step explanation:
Note that there are two " - " signs here. Thus, the end result will be " + "
We move from left to right, obtaining first 10/19 divided by (5/7):
10
----- ÷ (5/7)
19
To divide by (5/7), invert (5/7) and then multiply. We get:
10 7 2(7)
----- * ----- = ------- = 14/19
19 5 19
Answer:
1/5
Step-by-step explanation: First, turn 1/2 so that the denominator is the same as the other fraction (multiply both by 5 to get 5/10). Now subtract to get 2/10. Then, divide both by 2 to get the fraction in the simplest form.
