Answer:
c > 9
Step-by-step explanation:
(2c/3) + 1 > 7 subtract 1 from both sides
2c/3 > 7 -1
2c/3 > 6 (multiply both sides by 3)
2c > 6(3)
2c>18 (divide both sides by 2)
c > 18 / 2
c > 9
You can use the midpoint formulae as I have in the picture below
Answer:
an even number 120 times
a 3 40 times
a 4 or a prime number 160 times
Step-by-step explanation:
240÷6=40
3 even numbers
40x3=120
3 prime numbers and 1 4
4x40=160
Answer:
See below.
Step-by-step explanation:
40 + 15x = 30 + 19x
15x - 19x = 30 - 40
-4x = -10
x = 2.5
Two and a half hours.
Answer:
x = 
Step-by-step explanation:
Solve for x:
- x² + x² = 1²
- 2x² = 1
- x² = 1/2
- x = √(1/2)
- x = (√1)(√2)
Rationalize the denominator
Elminate the radical
- x = (√1 * √2)(√2 * √2) ⇒ Rationalize the denominator
- x = (√2)/(2)
