Answer:
B. C. and E.
Step-by-step explanation:
2a + 3b = 6 --> Equation 1
5a + 2b = 4 --> Equation 2
Equation 1 * 5 --> 10a + 15b = 30
Equation 2 * 2 --> 10a + 4b = 8
Equation 1 - Equation 2 --> 11b = 22 --> b = 2
Sub b=2 in Equation 1 (or 2, either works):
2a + 3b = 6
2a + 3(2) = 6
2a + 6 = 6
2a = 0
a = 0
b = 2, a = 0
Answer:
x < -10/7
Step-by-step explanation:
Divide both sides by -7. Because this divisor is negative, we must reverse the direction of the inequality sign, obtaining:
-7x < 10
----- < -----
-7 -7
Then x < -10/7
The answer you're looking for is 3/5
Use the given formula
C = 2(pi)r
Given pi = 3.14, r = 4
C = 2(3.14)(4) = 25.12 inches
Solution: 25.12 inches
