If 4 < b < 5, then -4 > -b > -5, or -5 < -b < -4.
Then
3 < a < 4 ==> 3 - 5 < a - b < 4 - 4 ==> -2 < a - b < 0
Answer:
80
Step-by-step explanation:
180-100=80
Consecutive integers are 1 apart so they are n and n+1
their sum (add) is at least 7
sum<u>></u>7
sum means add
n+n+1<u>></u>7
2n+1<u>></u>7
minus 7 both sides
2n<u>></u>6
divide 2
n<u>></u>3
the smaller number mist be at least 3, (making the bigger number at least 4)
At very minimum, move (4/5)x to the other side of the given equation. Then:
-(4/5)x + y = 0.85. This is the equation in standard form.
Answer:
x = 7
angle A = 7(7) + 4 = 49 + 4 = 53°
angle B = 4(7) + 9 = 28 + 9 = 37°
Step-by-step explanation:
m ∠A + m ∠B = 90° Complementary angles sum = 90°
7x + 4 + 4x + 9 = 90
11x + 13 = 90
11x = 77
x = 7
angle A = 7(7) + 4 = 49 + 4 = 53°
angle B = 4(7) + 9 = 28 + 9 = 37°
Check = angle A + angle B = 90° checked
