100 pts help me please.

Answer:

Carly's expenditure was $240 and the number of boxes of cards was required is 24 boxes.

Step-by-step explanation:

We know that:

48 + 8(b) = Carly's expenditure
10(b) = Carly's expenditure
48 + 8b = 10b
B = Boxes of cards

Work:

48 + 8b = 10b
=> 48 + 8b - 8b = 10b - 8b
=> 48 = 2b
=> b = 24

Now, let's substitute the value of b into any equation.

10(24)
=> 240

Hence, Carly's expenditure was $240 and the number of boxes of cards was required is 24 boxes.

Hoped this helped.

ILL GIVE BRAINLEST Determine whether the two angles in each figure are complementary, supplementary, or neither

Firdavs [7]

Answer:

Step-by-step explanation:

If the sum of two angles = 180°

Then the pair of angles will be supplementary.

If the sum of two angles = 90°

Then the pair of angles will be complementary.

Sum of angles having measures 98° and 82° = 98° + 82°

= 180°

Therefore, both the angles will be supplementary.

Sum of angles having measures 134° and 36° = 134° + 36°

= 170°

Therefore, these angles are neither supplementary nor complementary.

So the answer is NEITHER.

Determine the value of y in the proportion 6y−10/5+7y =12 .

ira [324]

its none of them? 6y - 10/5 +7y = 12 10 divided by 5 equals 2

it will now look like this: 6y - 2 + 7y = 12

then your going to want to add 2 to both sides of the equation.

it will now look like this: 6y -2 + 7y + 2 = 12 + 2 = 14

simplify: 6y + 7y = 14

add the like terms: 13y = 14

Name the relationship: complementary, linear pair, vertical, or adjacent.

mihalych1998 [28]

Answer:

1. Supplementary and Linear pair, 2. Adjacent, 3. Adjacent, 4. Complementary and adjacent, 5, Vertical, 6. Adjacent

Step-by-step explanation:

1. is a Linear pair because the two angles form a straight line, this means they are also supplementary because the two angles must add up to 180 degrees which is a straight line.

2. Are adjacent angles, because they share a common side and do not share any interior points.

3. Are adjacent angles, because they share a common side and do not share any interior points.

4. These angles are complementary and adjacent. They both sum to 90 degrees which makes them complementary. They are also adjacent angles, because they share a common side and do not share any interior points.

5. These are vertical angles because they are opposite angles made by intersecting lines.

6. Are adjacent angles, because they share a common side and do not share any interior points.
