Answer:
a = -2
Step-by-step explanation:
g(x) = 3/2x + 3
g(a) = 0
g(a) = 3/2a +3 =0
Subtract 3 from each side
3/2a +3-3=0-3
3/2a = -3
Multiply each side by 2/3
2/3 * 3/2a = -3*2/3
a = -2
Answer:
6/5 is the reciprocal of 5/6
Step-by-step explanation:
The reciprocal of a number is its multiplicative inverse. That is, the product of the number and its reciprocal is 1, the multiplicative identity element.
For a fraction, the reciprocal is the fraction with numerator and denominator interchanged. That is, the reciprocal of 5/6 is 6/5.
You can check that this is the multiplicative inverse by multiplying it by 5/6:
5/6 × 6/5 = (5×6)/(6×5) = 30/30 = 1 . . . . the multiplicative identity element

Step-by-step explanation:
<u>Step 1: Set up equation</u>
m∠LMN and m∠NMP must add up to m∠LMP
(2x - 1)° + (5x + 3)° = 107°
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 7x + 2 = 107
- Isolate <em>x</em> term: 7x = 105
- Isolate <em>x</em>: x = 15
<u>Step 3: Find m∠LMN</u>
- Define: m∠LMN = (2x - 1)°
- Substitute in <em>x</em>: m∠LMN = (2(15) - 1)°
- Multiply: m∠LMN = (30 - 1)°
- Subtract: m∠LMN = 29°
It would be (-5,4) because is all you need to found it the number of spaces there is and just found the same as the other side.
Since 1000ml is 1L, 100 ml is 1/10L.
So 100ml costs 7p
And 400ml costs 28p.
