Answer:
x = (164 - y)/5
y = 165 - 5x
Step-by-step explanation:
A whole rotation is 360° (All the angles together = 360°)
148 + 2x + 47 + y + 3x = 360
195 + 5x + y = 360
165 = 5x + y
y = 165 - 5x
5x = 165 - y
x = (164 - y)/5
Answer:
12 and 4
Step-by-step explanation:
We could set up two equations with the given information.
Let a be the larger number, and b be the smaller number.
4b - 4 = a (Four subtracted from four times the smaller is equal to the larger number.)
2a = 6b (Twice the larger number equals six times the smaller number.)
With the 1st equation, we could substitute a = 4b - 4 into the second equation.
We get
2(4b-4) = 6b
8b - 8 = 6b
2b = 8
b = 4
Substituting back into the first equation,
a = 4(4) - 4 = 12
Therefore the two numbers are 12 and 4.
2:3 because 10:15 simplified is 2:3
Answer:
x= -1
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
