The answer to this is a=3.6
Since they decided to be extremely ridiculous and deleted my answer for "not showing enough work", here I am again:
Since it says that Kiwi is 13 less than TWICE Granny's age, I divided 77 (Granny's age) by 2, which gave me 38.5
I then subtracted 13, since it says that she is thirteen less than that number, which gave me 25.5
I had originally said "20 or 20 and a half years old" because depending on your format of testing/worksheet, you may not have the option of putting halves.
Answer: 69
Step-by-step explanation:
First add all your positive numbers 37 + 58 = 95
Then add your negative numbers -17 + -9 = -26
Finally, subtract
95
-26
___
69
The answer is positive because the positive number 95 was higher than the negative number -26.
Hope this helps you!
We have the 2 equations
1- ) 5x-8y=6
2-) -6x-3y=18
multiplying the first equation by 3 and the second equation by 8 then subtracting
1-) 15x-24y=18
2-) -48x-24y=144
-48x-24y=144
(-) 15x-24y=18
-------------------------------------
-63x = 126
x=-2
substituting in equation 1
5(-2)-8y=6
-10-8y=6
-8y=16
y=-2
the soultion is (-2,-2)
