Answer:
Step-by-step explanation:
To convert temperatures in degrees Fahrenheit to Celsius, subtract 32 and multiply by .5556 (or 5/9).
5F= -15C
39F= 3.9C
Answer:
y=-9/2, x=7
Step-by-step explanation:
You can solve this via substitution. First solve for x in terms of y in one of the equations given. Lets use the first one:
25+4y=x
Now plug 25+4y in for x in the second equation
3(25+4y)-2y=30
75+12y-2y=30
75+10y=30
10y=-45
y=-9/2
Plug this into the first equation:
25-x=-4(-9/2)
25-x=18
x=7
Answer:
228 inches
Step-by-step explanation:
The scale is 12 inches : 5 yards, that means
Real Life 5 yards is 12 inches in drawing.
This is a ratio
We can write:
Now we can create another ratio where drawing length is "x" and real length is 95 yards.
<u>Note:</u> remember to keep yards on numerator and inches on bottom
So, we can write:
We can equate these 2 ratios and cross multiply and solve for x:
Hence 95 yards would be equal to 228 inches in the drawing
