Answer:
see explanation
Step-by-step explanation:
Given
x + 
≤ - 3 or x - 3 > - 2
Solve the left and right inequalities separately, that is
x + ≤ - 3 ( isolate x by subtracting from both sides )
x ≤ - 3 - , that is
x ≤ - 
- , thus
x ≤ - 
OR
x - 3 > - 2 ( isolate x by adding 3 to both sides )
x > 1
Solution is
x ≤ - or x > 1
The answer is, x-5 equals to 0. So x equals to 5. So your answer is 5.
X = bessie and y = betty
x + y = 1464
y = 2x - 375
x + 2x - 375 = 1464
3x - 375 = 1464
3x = 1464 + 375
3x = 1839
x = 1839/3
x = 613 <== Bessie gave 613 gallons
y = 2x - 375
y = 2(613) - 375
y = 1226 - 375
y = 851 <== Betty gave 851 gallons
B = 26in, c = 40in
a^2 = 26^2 + 40^2
= 2276 (square root it)
a = 2root569 // 47.7in
