X=alice
b=barry
c=charlene
x=15 more than b
x=15+b
c=2 times of b
c=2b
all together
x+c+b
15+b+2b+b
15+4b
they have 15+4b or 15+4 times of barry
if we want in terms of x
x=15+b
x-15=b
15+4(b)
15+4(x-15)
15+4x-60
4x-45
they have 4x-45 together
Answer:
2.598cm
Step-by-step explanation:
Area of a triangle =1/2 * base * Height
Given
ARea = 39.6cm^2
Base= 12in = 2.54 * 12
Base = 30.48cm
Required
Height
Substitute
39.6 = 1/2 * 30.48 * H
39.6 = 15.24 * H
H = 39.6/15.24
H = 2.598cm
Hence the height of the triangle is 2.598cm

Step-by-step explanation:
1)Simplifying<span>y = 2.2x + 3
Reorder the terms:
y = 3 + 2.2x
Solving
y = 3 + 2.2x
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Simplifying
y = 3 + 2.2x Hope i helped</span>
