Answer:
Step-by-step explanation:
MORE THEN IMPLIES + SIGN. SO NO
GREATER THAN IMPLIES AN INEQUALITY. SO YES
BELOW ALSO IMPLIES AN INEQUALITY BUT THE SIGN IS > NOT <. SO NO
ABOVE EIGHTEEN CAN WORK (NEVER HEARD IT PHRASED THIS WAY). SO YES
LESS THAN EIGHTEEN IS NO BECAUSE WE WANT GREATER THEN EIGHTEEN. SO NO
Answer:
Bill is 25 years old and Jenny is 29 years old
Step-by-step explanation:
Systems of Equations:
J = 4 + B
J + B = 54
Substitute J into the first equation.
4 + B + B = 54
Add like terms.
4 + 2B = 54
Isolate the variable.
4 + 2B = 54
-4 -4
2B = 50
2B/2 = 50/2
B = 25 years old
Plug in B into the second equation of the system.
J + B = 54
J + 25 = 54
Isolate the variable.
J + 25 = 54
-25 -25
J = 29 years old
Check your answer. Pick whatever equation in the system and plug in your answers.
J = 4 + B
29 = 4 + 25
29 = 29
Let the number be x
11 times the number : 11x
seven subtracted from the number : 11x - 7
Answer is -238:
11x - 7 = -238
11x = -231
x = 21
11x + 238
