Answer:
y = 8 + x or
Keesha.cousin.age = 8 + Keesha.age
Step-by-step explanation:
II. When Keesha.cousin is older than Keesha 8 years
Give y = 8 + x, when y is Keesha cousin.age, x is Keesha.age
y = 8 + x
II. Prove by given Keesha is 10 years old.
y = 8 + 10
y = 18 or Keesha cousin is 18 years old.
Hope that help :)
Answer: 2x^2
The three terms are
2x^2
-3x
5
as they are separated by a plus sign. You can think of it as 2x^2 + (-3x) + 5 if you want. The quadratic term is the term with the exponent of 2
20 is a multiple of 10
It is neither for 30.
Answer:
a = -5
Step-by-step explanation:
Given
-18 + 2a = 2(3a + 1)
Expand the bracket on the right
-18 + 2a = 2 x 3a + 2 x 1
-18 + 2a = 6a + 2
Add 18 to both sides
-18 + 18 + 2a = 6a + 2 + 18
2a = 6a + 20
Subtract 6a from both sides
2a - 6a = 6a - 6a + 20
-4a = 20
Divide both sides by -4
-4a/-4 = 20/-4
a = -5
