<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
a) 23 + (-16) + 42 * 5 - (-3)
= 23 - 16 + 210 + 3 = 220
b) -6(12 - 15) + 23
= -6(-3) + 23 = 18 + 23
= 41
c) -50 + (-10) + (5 - 3)4
= -50 - 10 + 2(4) = -50 - 10 + 8
= -52
d) -4.5 (-0.53) + (-1)
= 2.385 - 1
= 1.385
e) 5 - 2 + 8
= 3 + 8
= 11

Answer:
Sydney is 44 years old
Step-by-step explanation:
<u>Step 1: Make a system of equations
</u>
d = s - 15
<em>d + s = 73
</em>
<u>Step 2: Plug in s - 15 for d in the second equation and solve
</u>
s - 15 + s = 73
2s - 15 = 73 + 15
2s / 2= 88 / 2
<em>s = 44
</em>
Answer: Sydney is 44 years old
Answer:
The answer is "quotient =2x+5 and remainder =6x+1".
Step-by-step explanation:
Some of the data is missing that's why defined this question as follows:
Given:
when we divide the above value it will give the quotient =2x+5 and remainder =6x+1.
Answer: n=0 or n=2
Step-by-step explanation: Step 1: Subtract 2n from both sides.
n²−2n=2n−2n
n²−2n=0
Step 2: Factor left side of equation.
n(n−2)=0
Step 3: Set factors equal to 0.
n=0 or n−2=0
n=0 or n=2
