Answer:
Add the equations to eliminate x
Step-by-step explanation:
Let's go through each of these statements
1) Add the equations to eliminate x
y = x + 10
+
y = -x + 3
_______
2y = 13
This works!
18. s = 5r^2 + 7......making r the subject
s - 7 = 5r^2
(s - 7) / 5 = r^2...by taking the sqrt of both sides, it eliminates the ^2
( sqrt (s-7)/5) = r
19. h = ut - 1/2gt^2....u = 100, t = 1 4/5(or 9/5)...g = 6.4
h = (100)(9/5) - 1/2(6.4)(9/5^2)
h = 180 - 1/2(6.4)(3.24)
h = 180 - 3.2(3.24)
h = 180 - 10.368
h = 169.632 or 169 79/125
20. sorry..do not know this one
Answer:
1:200
5.6 cm^2 : y (as actual area)
y = 200 mutifly 5.6 cm^2
y= 1120 cm^2
We know 1m =100cm
so, 1m^2 =100cm x 100 cm = 1000cm^2
y= 1120 m^2/ 100x100
= 0.112 m^2
