Answer:
The answer is C
Step-by-step explanation:
table with a 10 in radius
Answer:
70
Step-by-step explanation:
i added 30% and 40
As the 2 quadrilaterals are congruent the sides of one quadrilateral are equal to the corresponding sides of the other quadrilateral
Hence,
AB = PQ
RQ = BC
AD = PS
DC = RS
Since terms for both AB and PQ are given we can equate the terms and find m
5m -9 = m + 11
5m -m = 11 + 9
4m = 20
m = 5
Correct answer is D , 5
-4 1÷5 - (- 13 1÷10)
first we should turn these into improper fractions by multiplying the whole number by the denominator then add the numerator.
4 × 5 = 20 + 1 = 21
13 × 10 = 130 + 1 = 131
(-21/5) - (-131/10)
To subtract fractions we want to find a common denominator so we can multiply the numerator and denominator of (-21/5) by 2 to get (-42/10)
(-42/10) - (-131/10)
Since we are subtracting a negative, that becomes a positive
(-42/10) + 131/10
131 - 42 = 89
89/10
Now we can change it back into a mixed fraction:
8 and nine-tenths or 8 9÷10
