Answer:
(2,14)
Step-by-step explanation:
Since y=5x+4, you can plug that into the other y in the other equation which would give you x+12=5x+4
Now subtract 12 from both sides
x=5x-8
Subtract 5x from both sides
-4x=-8
Now you divide them both by -4 which gives you x=2
Now plug x in to any of the equations
y=5(2)+4
y=10+4
y=14
Your final answer is (2,14)
77,000. Since the 9 is in the hundreds place and the 6 is in the thousands place you go to the left of the 6 (in this case the 9) and see if it's five or more, if it is then you move it up but if it's four or less you keep it he same.
Answer:
60 square inches
Step-by-step explanation:
Area = length x width
L = 12 inches
W = 5 inches
Area = 12 x 5
= 60 square inches
To solve for a variable, we simply need to isolate the variable and simplify all other terms. We can do this by performing the opposite operations to both sides.
In this case, we also need to remember that if our fractions have different denominators, we multiply the numerator and the denominator by whatever value makes them have equal denominators. That is 3, here.
z-4/9-1/3=5/9
+4/9 +4/9
z-1/3=9/9
z-3/9=9/9
+3/9+3/9
z=12/9
Using the math above, we can see that z=12/9 or 1 1/3.
Answer:
180 miles
Step-by-step explanation:
The are moving towards each other at 50 mph and 40 mph which is the same as 90 mph. They are moving 90 mph closer to each other every hour so in 2 hours it would be 180 miles.
