Two friends bought a pizza for $18.00. Each person bought their own drink. The total cost of the lunch is represented by the expression (2x + 18). Factor that expression by 2 to find out the cost of the lunch for each person.

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?

step-by-step explanation:

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
