Solve the inequality 7a + 13 < 48. A. a = 5 B. a ≤ 5 C. a < 5 D. a > 5
1 answer:
Answer:
C
Step-by-step explanation:
We know that 7a+13<48. This inequality can be simplified by rearranging.
Subtracting 13 from both sides: 7a<48-13
Therefore this becomes: 7a<35
Dividing both sides by 7: a<5
Since the inequality simplifies to a<5, the answer is C

Answer:
the value of m = 28°
Step-by-step explanation:
the sum of adjacent angles which form linear pair is 180°
so,
=》3m - 6° + 3m + 18° = 180°
=》6m + 12° = 180°
=》6m = 180° - 12°
=》m = 168° ÷ 6
=》m = 28°

For question 1 we can round 115 to 100, 5x100 is 500 which is closer to 545 than 7x100 = 700.
Answer:
To divide 0.8 divided by 20 she needs to annex a 0 in the hundredths place. So, the quotient is 0.04, and Carly is correct

Step-by-step explanation: My reasoning behind is that 70 percent of the neighborhood wants a playground if it is 40 to 17
Line r is twice line m. i.e. r = 2s which means that they are linearly dependent.
Therefore there are infinitely many solution to the given set of equations.
