A parking lot has spaces reserved for motocyles, cars and vans. There are five more spaces reserved for vans than motorcycles. T
77julia77 [94]

Answer:

  • motorcycles: 20
  • vans: 25
  • cars: 135

Step-by-step explanation:

There are 3 car spaces for each non-car space, so the number of car spaces is 3/4 of the total: (3/4)×180 = 135.

The number of motorcycle spaces is half of 5 less than the remainder, so is ...

  (180 -135-5)/2 = 20

and van spaces are 5 more than that: 25.

There are 20 motorcycle spaces, 25 van spaces, and 135 car spaces.

15 is 9 more than j.
Zina [86]

Answer:

j = 6

Step-by-step explanation:

"Is" typically means equals. "More than" means it is added to.

So 15 equals j with 9 added to it.

15 = 9 + j

Now solve for j by subtracting 9 from both sides.

15 - 9 = j

j = 6

Answer:

<em> SSS</em><em> can be used to prove that the given triangles are congruent.</em>

Step-by-step explanation:

In the given two triangles ΔADC and ΔABC,

  1. AD = AB = 7 units,
  2. CD = BC = 8 units,
  3. AC is common to both triangles,

Hence, ΔADC ≅ ΔABC by Side-Side-Side (SSS) congruence.

SSS congruence-

If three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent.
