Please help me asap help. The other two options are 6 2/8 and 6 1/4
Pavlova-9 [17]

Answer:

6 1/2

Step-by-step explanation:

To double the recipe we would need to multiply all the ingredients by 2. But since it is asking about the peaches, we only need to multiply 3 1/4 by 2. First we make the 3 1/4 to an improper fraction. (multiply denom. by the 3 then add the numerator. then keep the same denominator). The improper fraction of 3 1/4 would be 13/4. Now we can multiply by 2. That would give us 26/4 which reduces to 13/2. To change this back to a mixed number, we divide 13 by 2. That would give us 6 with a remainer of 1. So our answer is 6 1/2. Sorry if it's confusing hope it helps :)

Please help me solve question 2
sergiy2304 [10]

Answer:

solution: ( 3 , 6 )

\sf y =6

\sf x =3

Step-by-step explanation:

\sf y = \frac{2}{3} x+4

\sf 2x+3y = 24

make y the subject in equation 2:

\sf 2x+3y = 24

\sf 3y = 24-2x

\sf y = \frac{24-2x}{3}

insert this in equation 1:

\sf \frac{24-2x}{3} =\frac{2}{3} x+4

\sf \sf \frac{24-2x}{3} =\frac{2x+12}{3}

\sf (24-2x) = (2x+12)

\sf -2x-2x=12-24

\sf -4x=-12

\sf x =3

solve for y:

\sf y = \frac{24-2x}{3}

\sf y = \frac{24-2(3)}{3}

\sf y =6
