Answer:
7−2x
Step-by-step explanation:
1 Collect like terms.
(4+3)+(-7x+5x)
(4+3)+(−7x+5x)
2 Simplify.
7-2x
7−2x
Step-by-step explanation:
0 is right in the middle of all negative and all positive numbers.
0 is therefore larger than any negative number and smaller than any positive number.
and 0×n = 0, always, no matter what n is.
-0 = +0 = 0.
so, of course, only
4.1m > -16.4
is correct.
0 is not greater than 16.4.
0 is not smaller than -16.4.
Answer:
140
Step-by-step explanation:
We can find the number of houses from ...
# houses = (houses/flats)(flats/bungalows)(# bungalows)
= (7/4)(8/5)(50)
# houses = 140

Step-by-step explanation:
Answer:
x=2 y=-5
Step-by-step explanation:
7x-y=19
2x-3y=19
Multiply the first equation by -3
-3(7x-y)=19*-3
-21x +3y =-57
Add this to the second equation to eliminate y
-21x +3y =-57
2x-3y=19
-----------------------
-19x = -38
Divide by -19
-19x/-19 = -38/-19
x = 2
Now we need to find y
7x-y = 19
7(2) -y =19
14 -y =19
Subtract 14 from each side
14-14 -y=19-14
-y=5
Multiply by -1
y = -5
