Answer:
$25.50
Step-by-step explanation:
8.50 is apparently 1/3 of his money, so he had 3*8.50 = 25.50
Answer:
I can't see that very good, but I counted 8 units.
Step-by-step explanation:
Answer: BC is 9 units long
==============================================================
Work Shown:
Let x be the length of segment BC.
BC is parallel to DE, so this means that triangle ABC is similar to triangle ADE.
Side AB pairs with side AD (both are horizontal sides of triangle ABC and triangle ADE respectively)
Side BC pairs with side DE (both are vertical sides of triangle ABC and triangle ADE respectively)
Because of those facts above, we can end up with this proportion
AB/AD = BC/DE
-------------------
Let's plug in the given values and isolate x
AB/AD = BC/DE
12/20 = x/15
12*15 = 20*x ... cross multiply
180 = 20x
20x = 180
20x/20 = 180/20 ... divide both sides by 20
x = 9
Segment BC is 9 units long.
note: There is no need to calculate the length of segment AE. Though you are correct in stating that AE = 25.
Answer:
10
Step-by-step explanation:
You can do 5+5=10 or you can do 5x2=10. You can also do it this way but it is the longer way 1+1+1+1+1+1+1+1+1+1.
Answer:
x is y less than z
Step-by-step explanation:
The given equation is x + y = z
This equation relates the whole numbers x, y, and z.
This equation can be rearranged to make x the subject of the formula or to make y the subject of the formula. When this is done, the relationship between the terms or numbers would be clearly expressed.
Making y the subject of the formula, it becomes
y = z-x (this shows that z is greater than y by x)
Making x the subject of the formula, it becomes
x = z-y (this shows that z is greater than x by y)
Looking at the options given, the correct comparisons between z and x is
x is y less than z
