Answer:
b = - 0.389
Step-by-step explanation:
38/99=b+17/22
to solve this expression we would make b the subject of the formulae
and evaluate the other parameters.
38/99=b+17/22
collect the like terms
38/99 - 17/22 = b
22( 38) - 99 (17)/ 2178 = b
836 - 1683/2178 = b
-847/2178 = b
b = - 0.389
Answer:
7.5 cm
Step-by-step explanation:
it is a right triangle, b=10, hypotenuse c=12.5
a^2+b^=c^2 the Pythagorean theorm
a^=c^2-b^2
a^2= 12.5^2-10^2
= 56.25
a=√56.25=7.5 cm
Pretty sure that both A and B are correct
Answer:
No solution
Step-by-step explanation:
2x -y =7
y= 2x +3
- Substitute the y value. <em>2x-(2x+3)=7 or 2x -2x-3=7 </em>
- Eliminate opposites <em>2x <u>-2x</u>-3=7 >>>> -3=7</em>
- Answer <em>-3= 7</em> ( false)
The decimal equivalent of 1/18 is 0.125
