Answer:
Step-by-step explanation:
1. Symbolically, we get: 62 - 5x < 40
2. y - 7.3 < 3.4. Solve for y by adding 7.3 to both sides, obtaining:
y < 10.7 This is both the 'range' and the 'solution'
3a) 4b = 9b + 45, or -5b = 45, or b = -9
3b) 5a + 10 = 4a - 4
Combining like terms results in a = -14
Hmmmm I may be correct or may be wrong 22 x x = 33,895
M’lea should answer 21 answers correctly out of 30 questions, because the ratio is 3/10 if you multiply by 3 on 3/10 you get 9/30 which means she gets 9 answers wrong so you subtract the 9 to 30 and you get 21
The answer is 21
tangent(x) = (opposite side) / (adjacent side)
= (57 / 29)
= 1.96551....
According to my calculator,
The angle whose tangent is 1.96551... = 63.034... degrees .
The nearest whole degree = 63 degrees.
If it is a triangle, the total degree should be equal to 180.
So the last angle
180 - (35+45)
180 - 80
100
