Answer:
Step-by-step explanation:
25+105+x=180 degree(being sum of the interior angles of a triangle)
130+x=180
x=180-130
x=50 degree
Shea bought 13.5 pounds of corn
c = pounds of corn
b = pounds of beans
Here’s what we know:
c(0.99) + b(0.45) = 18.09
c + b = 24
Solve the second equation for c in terms of b
c = 24-b
Substitute that expression for c in our first equation to get a numerical solution for b:
0.99 (24-b) + 0.45b = 18.09
23.76 - 0.99b + 0.45b = 18.09
-0.54b = -5.67
b = 10.5
Substitute that value to get a numerical value for c:
c = 24 - b
c = 24 - 10.5
c = 13.5
Check the math:
0.99(13.5) + 0.45(10.5) =
13.365 + 4.725 = 18.09
Your answer would be <u>Ninety seven and sixty ninths.</u> Hope this helps!
The correct answer would be 150 ^-^
Answer:
40
Step-by-step explanation:
If Whitney was driving x speed, her mother was driving x+5. Multiply that by the distance each traveled, and you have an equation that looks like this:
8(x+5) = 7(x)
Simplify it and you get:
8x + 40 = 7x
Now solve regularly:
8x-8x + 40 = 8x - 7x
40 = 1x
40 = x
Whitney's speed: 40
Her mother's speed: 45
