Answer:
-25, -5
Step-by-step explanation:
Let's write a system of equations. Lets call x and y the numbers, where x is 5 times y.
x + y = -30
x = 5y
Plugging this in, we get:
5y + y = -30
y = -5
Since y = -5, we can plug this in, and see that x = -25.
Answer:
x = -9
y = 2
Step-by-step explanation:
x + y = -7 then x = -y - 7
-x + 4y = 17
substitute for x:
-(-y - 7) + 4y = 17
reduce:
5y = 10
y = 2
x = -2 - 7
x = -9
check:
-9 + 2 = -7
-7 = -7
-(-9) + 4(2) = 17
17 = 17
Answer:
x+3 > 21

Answer:
Below.
Step-by-step explanation:
About x3 bigger then figure b.
The answer is x=5/8. The reason for this is when you divide it equal 0.625 then when you multiply that by 2 it equals 1.25. After you do that you add 5 which is 6.25. Now we divide 4/5 which is 0.8. Now, we multiply 6.25x0.8=5. 5-4=1. Therefore your answer is 5/8. Hope this helps :)
