Mom put plums and apples onto a plate. The ratio of the number of plums to the number of apples was 3:2. How many fruit did mom

Delvig [45]

Answer:

30 fruits

Step-by-step explanation:

Let

x ----> number of plums on the plate

y ----> number of apples on the plate

we know that

The ratio of the number of plums to the number of apples was 3:2

$\frac{x}{y} =\frac{3}{2}$

$x=1.5y$ ----> equation A

After Ed took 6 plums from the plate, the number of plums remaining on the plate became the same as the number of apples

$x-6=y$ ----> equation B

substitute equation A in equation B

$1.5y-6=y$

solve for y

$1.5y-y=6\\0.5y=6\\y=12$

Find the value of x

$x=1.5(12)=18$

therefore

Mon put on the table

$x+y=18+12=30\ fruits$

What is the solution to the system of equations?<br><br> y = –5x + 3<br><br> y = 1

Alinara [238K]

Ok so we know that y=1 so we can simply sub in the value of y into the equation :

y = -5x +3

1 = -5x +3

Move the -5x to the LHS ( Left-hand-side ) therefore it changes sign as well move 1 to the RHS ( Right-hand-side ) it also changes sign.

5x = 3 - 1

5x = 2

x = 2/5

x = 0.4

Hope this helps :).
