Answer:
2 cm = 21 km
Step-by-step explanation:
2 cm = 21 km
This is why
3cm = 31.5 km
3/3 = 31.5/3 (To find out how much 1 cm is equal to)
1 cm = 10.5 km
And since 1 cm = 10.5 km is not there in the options... I tried to find out for 2 cm
So, I multiplied both sides by 2
1 cm = 10.5 km
1 *2 = 10.5 *2
So the answer become 2 cm = 21 km
Answer:
As a member, Tom's cost would be cheaper if he rents the courts 17 or more times.
Step-by-step explanation:
Let the number of times be x
If Tom is a member, and rents the courts x number of times, then he would pay
$135 + $3 × x = $135 + $3x
For a nonmember that rents x number of times, the nonmember would pay
$11 × x = $11x
Now, we are to determine which value of x for which $135 + $3x is less than $11x, that is
$135 + $3x < $11x
Solving the inequality,
$135 < $11x - $3x
$135 < $8x
$135 / $8 < x
16.875 < x
∴ x > 16.875
This means, for Tom's cost to be cheaper, he must have rented the court for more than 16.875 times. (Round 16.875 to the nearest whole number)
16.875 ≅ 17
∴ x > 17
Hence, As a member, Tom's cost would be cheaper if he rents the courts 17 or more times.
3.1/5 = 0.62 divide 5 into the 3 =0 divide 5 into 31 =6 bring down the 1add a zero
divide 5 into 10 = 2 answer is 0.62
Answer: x = 4 and x = -3/2
Procedure:
1) Given: 2x^2 - 5x - 12 = 0
2) Multiply both sides by : 2(2x^2) - 2(5x) - 2(12) = 0
3) Rearrange: (2x)^2 -5(2x) - 24 = 0
4) Notice that the common factor is (2x)
5) Set the parenthesis with the common factor inside:
(2x ) (2x ) =0
6) The first sign is the same sign of the second term of the trinomial, which is negative, the second sign is the product of the signs of the second and the third terms of the polynomial, which is (-)*(-) = + (positive)
(2x - )(2x + ) = 0
7) find two numbers that sum up - 5x and its product is -24.
- 8 + 3 = - 5
(-8)(+3) = -24
=> the numbers in the factors are -8 and +3
(2x - 8) (2x + 3) = 0
That is the factored equation. Now you can solve
8) a) 2x - 8 = 0 => 2x = 8 => x = 8/2 => x = 4
b) 2x + 3 = 0 => 2x = - 3 => x = - 3/2
Answer: the two solutions are x = 4 and x = -3/2
