Answer:
Step-by-step explanation:
I'm assuming that your "70=50x what is xx" actually means "find x if 70-50x = 0" If that's not what you meant, please retype your question.
Dividing both sides by -50 results in -70/50 + x = 0, and adding 70/50 to both sides results in x = 70/50, or 7/5.
Only if my assumptions are correct: x = 7/5.
Answer:3 by 1
Step-by-step explanation:
okay so I'll say the long side of a tile as x
the short side of a tile as y
look at the short side of the big patio first, it's made up of 2 big and 2 small
so 2x+2y=8 or x+y=8 so two added together is 8. So one possibility is 3 and 1 because (3+1)2 = 9
Tamika ran the fastest time at 21.6 seconds in 120 meters because the faster you run the less time you have on your timer.
Answer:
Step-by-step explanation:
y+ 20= x+ 15( Vertically opposite angles)
y+ 20- 15= x
x= y+ 5 __(1)
3x+ 5=4y- 15
Substituting (1)
3(y+5)+ 5= 4y-15
3y+15+5=4y- 15
y=15+20
y= 35
x= 40
