I need some help please
gizmo_the_mogwai [7]

Answer:

a) -10

b) 7

Step-by-step explanation:

a) 2(x + 3) = x - 4

=  > 2x + 6 = x - 4

=  > 2x - x =  - 4 - 6

=  > x =  - 10

b) 4(5x - 2) = 2(9x + 3)

=  > 20x -8 = 18x + 6

=  > 20x - 18x = 8 + 6

=  > 2x = 14

=  > x =  \frac{14}{2}  = 7

The ratio of red to blue marbles in a bag is 2:5. If there are 65 blue marbles in the bag, how many red marbles are there? Let x
hoa [83]

Answer:

first get the total ratio; 2 + 5 = 7

so the fraction of blue marbles is 5/7

then assume the number of total marbles to be k

then use the expression;

5/7*k = 65

7*5/7 * k = 65*7

5k =455

5/5k = 455/5

k = 91

then calculate the number if red marbles from;

x = 2/7*91

x = 26

Therefore there are 26 red marbles.
