Answer:
Step-by-step explanation:
a 2m+5=13
2m=8
m=4
b 3m/5=-6
3m=-30
m=-10
c 4-5x=19
-5x=15
x=-3
d x/4-10=2
x=48
e -24=8(h+3)
-24=8h+24
-48=8h
h=-6
f -3+d/2=9
-3+d=18
d=21
Answer:
No because they have different slopes
Step-by-step explanation:
(1 , 2) and (2, 4)
Slope:
m=(y2-y1)/(x2-x1)
m=(4-2)/(2-1)
m = 2
Answer:
6 : 11
Step-by-step explanation:
Given 2 similar figures with ratio of sides = a : b, then
ratio of areas = a² : b²
Here ratio of areas = 36 : 121, thus
ratio of sides = : = 6 : 11
45/117
Both numbers can be divide by 9
5/13
