Multiply the first equation by 7 and the second equation by 2, and then add.
Step-by-step explanation:
2f - 5g=-9
-7f + 3g=4
To eliminate any variable , we need to make the coefficients same with different sign and add it
the coefficient of 'f' in first equation is 2
the coefficient of 'f' in second equation is -7
We already have different sign so we make the coefficients same
To make the coefficient same , we multiply the first equation by 7 and second equation by 2
So equation becomes
14f - 35g = -63
-14f + 6g = 8
Now when we add both equations, 'f' gets cancelled
-29g = -55
X=-3 that’s the answer your welcome
70-q-q-2q= 80
combine like terms first
so you get 70-4q= 80
subtract 70 on both sides and you get -4q= 10
divide -4 on both sides and you get q= 10/-4 or -2.5
Answer:
Least to greatest is: 0.0625, 6.75% and 
.
Step-by-step explanation:
Given:
The three quantities to compare are:
6.75%, 0.0625, and
Let us convert each into percentage.
6.75% is already in percentage.
We multiply a number by 100 to convert it to percentage form.
So, 
Now, on comparing all the three percentage, we conclude that,
70% is the greatest and 6.25% is the least.
So, order from least to greatest is:
