Answer:
9
Step-by-step explanation:
Based on the algebraic rules for subtracting negative numbers,
when you subtract a negative number, the two negative signs cancel out and instead becomes an addition sign.
For example:
a - -b = a+b
-a - -b = -a + b
Therefore, following this rule,
the equation -51-(-60)
will change the -(-60) into a +60, so
-51 + 60
60-51 = 9
Answer: 10
Explanation: This is an equilateral triangle so all the angles are 60° since 180 ÷ 3 = 60.
Work:
60 = 5y + 10
-10 -10
50 = 5y
5 5
10 = y
Answer:
x+6=11
-6= -6
x = 5

Answer:
expression a
Step-by-step explanation:
The given expression is 15+0.25(d−1).
let suppose,
15 = a
0.25(d−1) = b
we get a + b
It clearly indicates the given expression is sum of two entities, we can exclude option b and option d.
Now we are left with option a and c, for that we have to evaluate the term b
b = 0.25(d−1) <u>that is the additional amount after d days</u>
Therefore, expression a is correct.
