Answer:
let mother's age y and daughter age x
a/q y=3x and y-5=5x-25
put y in second eq we get x=10 &y=30(their present age)
Answer:
2.1544
Step-by-step explanation:
![\sqrt[3]{10}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B10%7D)
= 2.1544
check: 2.1544^3
Answer:4x>2+3x+5
Step-by-step explanation:
12x>3+8x>2+9x>2+21x+10
12x>3+8x>2+9x>2+6x+15×10
4x^2(3x+2)+9x^2×6x
4x^2(3x+2)+3x(3x+2)+15x+10
4x^2(3x+2)3x(3x+2)+5(3x+2)
Cancel
3x+2(4×^2+3x+5)
_____________
3x+2
4x^2+3x+5
For this case we have a quadratic equation, 
, of the form 
Where:
We can solve the equation by factoring, that is, we bias two numbers that multiplied give as a result -60 and added as a result 28.
These numbers are:
Then, the factorization is given by:
The roots are:
Answer:
<span>we will isolate that right triangle marked off with the little angle thing.
</span>We know that, in that right triangle, one of the legs measures 22 ft, and the angle (adjacent) to it, meausres 9.2 degreesIn this case, <span>tan9.2=<span>x/22</span></span><span> where x is that unkown length
</span>cross multiply.
<span>your final answer is equal to x+5.6</span>
