Answer: 11 over 8 or 1 and 3 over 8
Step-by-step explanation:
3/4 is made into 6/8. Add 6/8 to 5/8 and you get 11/8 which is equal to 1 and 3/8.
18 is no solutions
24 is x=6
Answer:
x < -17 or x > 10
Step-by-step explanation:
|2x+7|>27
1)
2x + 7 > 27
2x > 20
x > 10
2)
2x + 7 < -27
2x < -34
x < -17
Solution:
It is given that Δ ABC is an Isosceles right triangle right angled at B.
Slope of AB= -1
Also, AB ⊥ BC
⇒So, Slope of AB × Slope of BC = -1→→[If two lines are perpendicular then product of slopes of two lines is -1.]
⇒(-1) × Slope of BC = -1
⇒ Slope of BC = 1
Now, ABC is dilated by a scale factor of 1.8 with the origin as the center of dilation, resulting in the image A'B'C'.
→Length of Line segment A'B'= 1.8 × AB
So, slope of two line Segment that is AB and A'B' are same.
Slope of A'B'= -1
⇒Length of Line segment C'B'= 1.8 × CB
So, slope of two lines that is CB and C'B' are same.
⇒ Slope of B'C' = 1
[3 + 18x = 45 ]
-3 -3
3 was the constant so we cancel the three by changing to the opposite . Then subtract the -3 from 45 which equals 42. After subtract 3 , you divide by the number that has a variable x is the variable
=18 divide by 42
x=21
