<em>(c) 53</em>
- Step-by-step explanation:
<em>Hi there !</em>
<em>we have a number ab</em>
<em>a + b = 8</em>
<em>ab - 18 = ba</em>
<em>10a + b - 18 = 10b + a</em>
<em>10a - a + b - 10b = 18</em>
<em>9a - 9b = 18 | + (9a + 9b)</em>
<em>9a + 9a - 9b + 9b = 18 + 9(a + b)</em>
<em>18a = 18 + 9×8</em>
<em>18a = 18 + 72</em>
<em>18a = 90</em>
<em>a = 90 : 18</em>
<em>a = 5</em>
<em>a + b = 8</em>
<em>5 + b = 8</em>
<em>b = 8 - 5</em>
<em>b = 3</em>
<em>ab = 53</em>
<em>Good luck !</em>
X = first place....and each place after that is 50 less
so 2nd place would be x - 50 and third place would be x - 100
so ur answers are :
b. x + (x - 50) + (x - 100)
f. 3x - 150 ...u get this when u combine like terms
Answer:
£107,714 > £107,674
Step-by-step explanation:
Given
£107,714 and £107,674
Required
Determine the relationship between them using > or <
From the given parameters, we understand that
£107,714 is greater than £107,674
The keyword greater than is represented mathematically with >
Hence:
£107,714 is greater than £107,674
becomes
£107,714 > £107,674
The two angles are corresponding angles, which means they are equal to each other. Make them equal to each other in an equation.
11x - 2 = 130
Add 2 to both sides.
11x = 132
Divide both sides by 11.
x = 12
4 + 6 = 10
10 * 4 = 40.
The full equation looks like this....
4(4+6)
"Some Number" is 6.
