Answer:400
x-85=315
Step-by-step explanation:
x-85=315 so then you add 85 to both sides and get x=400
32 units is the perimeter. I did thwart by adding up all sides.
7x2 = 14
9x2 = 18
14+18 = 32
Answer:
20 m/s
Step-by-step explanation:
560 m/25 s
=22.4 m/s
≈ 20 m/s ( nearest tenth of m/s )
Answer:
g >2 or g <2/3
Step-by-step explanation:
|3g-4| > 2
Absolute value equations have two solutions, one positive and one negative. When we take the negative, we have to flip the inequality
3g-4>2 or 3g-4<-2
Add 4 to each side
3g-4+4>2+4 3g-4+4 <-2+4
3g>6 3g<2
Divide each side by 3
3g/3 >6/3 3g/3 <2/3
g >2 or g <2/3
<span>15x-3y=27
5x+4y=14
multiply (2nd) equation by (3)
15x + 12y = 42
</span>15x - 3y=27
15x + 12y = 42
-------------------substract
-15y = -15
y = 1
15x-3y=27
15x-3(1)=27
15x - 3 = 27
15x = 30
x = 2
so now you have x = 2, y =1
