Parentheses affect how equations are done.
EX. 1+1*4
4+1=5
VS
(1+1)*4
2*4=8
Parentheses first. 1-4= -3. 4-3=1. 1-2=-1.
The answer is -1.
Answer:
6 weeks
Step-by-step explanation:
Total savings= $325
For every week, his total savings decrease by $28.
Let's form an expression for the amount of money left in his account after w weeks.
325 -28w= 157
28w= 325 -157
28w= 168
<em>Divide by 28 on both sides:</em>
w= 168 ÷28
w= 6
Thus, there are 6 weeks until he has $157.
Answer:
Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 4
