What is the ratio of oranges to apples? Write it as a fraction?

Iteru [2.4K]

Answer:

See below.

Step-by-step explanation:

3.)

There are 4 oranges and 6 apples so the fraction would be 4/6 which we can reduce to 2/3.

a.) As we stated beforehand, the fraction was 2/3. That means for every 2 oranges, there are 3 apples.

b.) We did this already. 4/6 was reduced to 2/3.

how can you find the slope using a graph?given 2 points?given an equation in slope intercept form?given an equation in standard

r-ruslan [8.4K]

Answer:

Yes you can find it

Step-by-step explanation:

The formula for slope is: (y2-y1)÷(x2-x1)

substitute the two given points to find the slope

so if you get the answer for slope as, say L or 5

then y=Lx+c or y=5x+c is the equation in slope intercept form

Then substitute one of the points in x and y's place to find the value of slope intercept (c in the previous equation)

say you get 8 then the standard equation will be y=5x+8

7. A vending machine only accepts dimes and quarters. There are 85 coins

Vladimir [108]

There are 55 quarters and 30 dimes in the machine.

Step-by-step explanation:

Total coins = 85

Total amount = $16.75 = 16.75*100 = 1675 cents

1 quarter = 25 cents

1 dime = 10 cents

According to given statement;

x+y=85 Eqn 1

25x+10y=1675 Eqn 2

Multiplying Eqn 1 by 10

$10(x+y=85)\\10x+10y=850\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(25x+10y)-(10x+10y)=1675-850\\25x+10y-10x-10y=825\\15x=825$

Dividing both sides by 15

$\frac{15x}{15}=\frac{825}{15}\\x=55$

Putting in Eqn 1;

$55+y=85\\y=85-55\\y=30$

There are 55 quarters and 30 dimes in the machine.
