Answer:390
Step-by-step explanation:130x3=390
Let's call the number "n"
if we write in an equation what you said it's like this:
n*2+4-n-3=n+1.
first i will move all the "n"s to the left and all the numbers to the right
n*2-n-n=1+3-4
which is....
0=0
this means that for EVERY number, if you double it, add four, subtract three, you will get this number plus one. <span />
Ok first lets take care of the color
given that you have 12 red triangles and the ratio for red triangles to blue triangles is 4:5
if 12=4 than blue=5
12 times 5= 60
12 times 4 = 48
48 red and 60 blue = triangles
48+60=108
there are 108 triangles in total
now since the ratio for triangle square or circle is
for every 3 triangles there are 6 squares and for every six squares there is one circle
t3:s6:c1
since there are 108 triangles
108/3=36
since for every 3 triangles there are 6 squares
six times 36(amount of triangles/3)
6*36+=216
so there are 216 squares
now it says for every six squares there is one circle
therefor (the amount of squares)216/6+= 36
we are back to 36 and there are 36 circles
Answer:
the larger number is 69
the smaller number is 16
Step-by-step explanation:
x is the smaller number
y is the larger number
x + y = 85
y - 4x = 5
y = 5 + 4x
x + 5 + 4x = 85
5x = 80
x = 16
y = 69
