Answer:
Step-by-step explanation:
1) 30 : 100 = x : 299
x = (30 x 299)/100
x = 89,70 $
2) 299 - 89,70 = 209,30 $
3) 5 : 100 = x : 209,30
x = 10,465 $
209,30 + 10,465 = 219,77 $
Answer:
This cannot be solved but it can be simplified
first we open the bracket
so we have
a²- abx/x = 2/3
next we cross multiply so it will be 3(a² - abx) = 2x
we get
3a² - 3abx = 2x
Next we factorise so we can get
3a(a-bx) =2x
I dont know what exactly you where asked but I hop this helps
Answer:
< Less Than and > Greater Than
This symbol < means less than, for example 2 < 4 means that 2 is less than 4. This symbol > means greater than, for example 4 > 2. ≤ ≥ These symbols mean 'less than or equal to' and 'greater than or equal to' and are commonly used in algebra. In computer applications <= and >= are used.
Step-by-step explanation:
77.5d + .14m
m = 425
.14 * 425 = 59.5
77.5d + 59.5 ≤ 230
77.5d ≤ 170.5
d ≤ 170.5/77.5
d ≤ 2.2
