A box contains 146 marbles which are either red or blue. there are 28 more blue marbles than red marbles. how many blue marbles

rusak2 [61]

R + b = 146. Supposing that b=r+28,

r + (r+28) = 146, or 2r + 28 = 146.

Simplifying: 2r = 118. Then r = 59, and b = r+28 = 59+28 = 87 blue marbles

Paws at play made a total of $1234 grooming 22 dogs. Paws at Play charges $43 to groom each small dog and $75 for each large dog

vitfil [10]

Answer:

Answer (a):

s + l = 22 ... (i)

43s + 75l = 1234 ... (ii)

Answer (b)

9 large dogs.

Step-by-step explanation:

Paws at Play made a total of $1234 grooming 22 dogs.

Paws at Play charges $43 to groom each small dog and;

$75 for each large dog.

Let the number of small dogs be 's'

And the number of large dogs be 'l'

A system of equations will be:

s + l = 22 ... (i)

43s + 75l = 1234 ... (ii)

Solving this set of simultaneous equations by elimination, we simply multiply (i) by 43 to get;

43s + 43l = 946 ... (i)

43s + 75l = 1234 ... (ii)

Subtracting (i) from (ii) we get;

32l = 288 , l = $\frac{288}{32}$ = 9

So there are 9 large dogs.

Dolly is measuring the angles of a triangle. He measures the first two angles of a triangle and gets 30 and 100. How could he fi

Natalija [7]

Answer:

the third angle is 50 degress

Step-by-step explanation:

the angle sum property states that the sum of all the interior angles of a triangle is 180.

therefore : 30 + 100 + x = 180

x = 180 - 130

x = 50
