3(x+5)=8x~~~First we distribute (we multiply 3 by x and 3 by 5)
3x+15=8x~~~Remove 3x from both sides
-3x -3x
15=5x~~~~Turn this equation around so x is on the other side
5x=15~~~Divide by 5x
÷5x ÷5x
x=3
35 total ribbons
x = white ribbons
x-3 = blue ribbons
x+2 = red ribbons
35= x+x-3+x+2
35= 3x -1
36 =3x
12 = x
12 white ribbons
9 blue ribbons
14 red ribbons
12+14+9 = 35
Answer:
Father's age = 64 years
Step-by-step explanation:
Given:
Mummy's age = Aliyah's age + 32
Father's age = Mummy's age + 8
Tota age = 144
Find:
Father's age
Computation:
Assume;
Aliyah's age = a
So,
Mummy's age = a + 32
Father's age = a + 32 + 8
Father's age = a + 40
Aliyah's age + Mummy's age + Father's age = Total age
a + a + 32 + a + 40 = 144
3a + 72 = 144
3a = 144 - 72
3a = 72
a = 24
Father's age = a + 40
Father's age = 24 + 40
Father's age = 64 years
Answer:
B.
Step-by-step explanation:
Since there is a dotted line, we know that the sign of inequality used will be either > or <.
Since the shaded area is above the dotted line, we know that the sign of inequality used will be >.
This corresponds to answer choice B.
Hope this helps!
