Answer:
The equation is q + 10 = 20
The solution is q = 10
Step-by-step explanation:
"sum" means an addition.
"sum of q and 10" means "q + 10".
"is" means "="
That means you have the equation
q + 10 = 20
To solve the equation, subtract 10 from both sides.
q + 10 - 10 = 20 - 10
q = 10
Answer:
The equation is q + 10 = 20
The solution is q = 10
Answer:
![f - g + (-2) = -9.7005](https://tex.z-dn.net/?f=f%20-%20g%20%2B%20%28-2%29%20%3D%20-9.7005)
Step-by-step explanation:
Given
f = -3.005
g = 4.7
Required
Evaluate: ![f - g + (-2)](https://tex.z-dn.net/?f=f%20-%20g%20%2B%20%28-2%29)
To do this, we simply substitute the values of f and g in the above expression
becomes
![-3.005 - 4.7 + (-2)](https://tex.z-dn.net/?f=-3.005%20-%204.7%20%2B%20%28-2%29)
Open the bracket
![-3.005 - 4.7 -2](https://tex.z-dn.net/?f=-3.005%20-%204.7%20-2)
![-9.7005](https://tex.z-dn.net/?f=-9.7005)
Hence;
![f - g + (-2) = -9.7005](https://tex.z-dn.net/?f=f%20-%20g%20%2B%20%28-2%29%20%3D%20-9.7005)
7/8 is greater because if you put the two fractions' denominator as the same one, than it is (2*8)/(3*8) and (7*3)/(8*3) which is 16/24 and 21/24 so 21/24 is greater which is also 7/8
Answer:
Step-by-step explanation:
The given expression is
.
We have to check which of he given options on simplification gives the same given expression.
(A) The expression is:
=![\frac{50x}{5x}](https://tex.z-dn.net/?f=%5Cfrac%7B50x%7D%7B5x%7D)
=![10](https://tex.z-dn.net/?f=10)
which is not equivalent to the given expression, thus this option is incorrect.
(B) The expression is:
=![10(10x)-1](https://tex.z-dn.net/?f=10%2810x%29-1)
=![100x-1](https://tex.z-dn.net/?f=100x-1)
which is not equivalent to the given expression, thus this option is incorrect.
(C) The expression is:
=![10(10x)+1](https://tex.z-dn.net/?f=10%2810x%29%2B1)
=![100x+1](https://tex.z-dn.net/?f=100x%2B1)
which is not equivalent to the given expression, thus this option is incorrect.
(D) The expression is:
=![\frac{50x}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B50x%7D%7B5%7D)
=![10x](https://tex.z-dn.net/?f=10x)
which is equivalent to the given expression, thus this option is correct.
(E) The expression is:
=![(\frac{50}{5})x](https://tex.z-dn.net/?f=%28%5Cfrac%7B50%7D%7B5%7D%29x)
==![10x](https://tex.z-dn.net/?f=10x)
which is equivalent to the given expression, thus this option is correct.
(F) The expression is:
=![x^5](https://tex.z-dn.net/?f=x%5E5)
which is not equivalent to the given expression, thus this option is incorrect.
