I believe #7 is c but i dont know the other one
1.. N + 4n -7n - 1
Answer:
m∠KMJ = 72°
Step-by-step explanation:
Since, ∠KMJ and ∠JMI are complementary angles.
Therefore,
m∠KMJ + m∠JMI= 90°
m∠KMJ + 18° = 90°
m∠KMJ = 90° - 18°
m∠KMJ = 72°
Answer:
It's 72 degrees

Answer: 684
Step-by-step explanation:
95% of 720
Move decimal point two places to the right.
0.95 * 720 = 684
Answer: 684
Step-by-step explanation:
95% of 720
Move decimal point two places to the right.
0.95 * 720 = 684
Let the unknown number be x then given,
(4/5)x - (3/4)x = 4
(16x - 15x)/20 = 4
x/20 = 4
x=80
Let the number be n.
Four fifths of the number is 4n/5.
Three fourths of the number is 3n/4.
Four fifths of a number is more than three fourths of the number by 4.
4n/5 = 3n/4 + 4
20 * 4n/5 = 20 * 3n/4 + 20 * 4
16n = 15n + 80
n = 80
Let's check.
4/5 of 80 = 4/5 * 80 = 64
3/4 of 80 = 3/4 * 80 = 60
64 is indeed 4 more than 60 showing that 4/5 of 80 is 4 more than 3/4 of 80, so 80 is correct.
Answer: 80
