Answer:
x = 0
Step-by-step explanation:
i) x - 11 + 1 < 15
x - 10 < 15
x < 10 + 15
x < 25
ii) x - 11 + 1 > 15
x - 10 > 15
x > 25
Therefore to compare (i) and (ii)
25 < x < 25
In any case, x = 0
Answer:
$1,956.95
Step-by-step explanation:
The school bought 47 sandwiches for $40.60
= 47 × 40.60
= 1,908.2
They also bought 39 bags of chips for $1.25
= 1.25×39
= 48.75
Therefore the total amount spent can be calculated as follows
= 48.75 + 1,908.2
= 1,956.95
Hence the total amount spent by the school is $1,956.95
Answer:
Step-by-step explanation:
A triangle adds up to 180.
180 - 50 = 130
Since both of the missing angles are congruent each of the missing angles is 65 degrees.
130/2 = 65
As per the exterior angle theorem, the measure of the exterior angle is determined by the sum of the opposite interior angles.
65 + 65 = 130
So, the measure of
