A bag contains blue marbles and red marbles, 107 in total. The number of blue marbles is 7 more than 4 times the number of red marbles. How many blue marbles are there?

red is 13.36

Blue is 93.625

Step-by-step explanation:

Let the red marbles be y

Based on the question,red is 4times which means 4y

And blue is 7times greater than red which means 7(4y)

Blue + red=107

7(4y) + 4y=107

28y+4y=107

32y=107

Divide both sides by 32

Y=3.34

Red =4y

Red= 4(3.34)

Red =13.36

Blue= 7(4y)

Blue=7(4×3.34)

Blue= 93.625

my acc plz

step-by-step explanation:

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
