3:7 =
3/7
3/7 = x/35
7x = 105
x = 15
answer : clara borrowed 15 books
Answer:
x=1 y=-5
Step-by-step explanation:
7(5x-2y=15) ---> 35x-14y=105
2(7x+7y=-28) --> + <u>14x+14y=-56</u>
49x=49 --->x=1
5(1)-2y=15 ---> 5-2y=15 ---> -2y=10 ---> y=-5
Answer:
(1, -1)
Step-by-step explanation:
If you replace y and x with (1 and -1) you have -1 - 2^1 < -3
And that equals -3 if solved. The sign says equal to or less than, so you answer is (1, -1)
200, because 8% is 8 parts of 100%. Then 1 part of that 100% is 16/8=2. Then 100% is the number i.e; 200
Your method is right so u already know how to do it
