I believe it’s C (11/15)

Sorry if I’m wrong but you need to find the common denominator which is 15 so you would times 1/3 by 5 so you have 5/15 then times 2/5 by 3 so you’ll have 6/15. 5+6 = 11 you don’t add denominators obviously.

Melinda bought 6 bowls for $13.20. what was the unit rate in dollars

Answers

To find the unit rate we will divide the amount of dollars ($13.20) by the amount of bowls (6). Then we will check our work. lets do it:-

13.20 ÷ 6 = 2.20
$2.20 per bowl

CHECK OUR WORK:-

2.20 × 6 = 13.20
we were RIGHT!!

So, the unit rate in dollars for, Melinda bought 6 bowls for $13.20 is, $2.20 per bowl.

Hope I helped ya!! xD

Just put this , 13.20/6 which is 2.20 so thats 2.20$ a bowl.
also you could , 2.20*6=13.20 , thats still 13.20 (2.20)

all together this means the unit rate in dollar is 2.20 for bowl , per bowl. for Melinda because she bought them for 13.20

i hope this helps.

Draw a quick picture for 37 . Draw to show how you would subtract 19 from 37 write to explain what you did

Answers

Answer:

Step-by-step explanation:

To Find : Draw to show how you would subtract 19 from 37 write to explain what you did

Refer figure

Total no. of triangles = 37

No. of pink triangles = 19

Total triangles - no. of pink triangles = no. of purple triangles

⇒37-19=18

Thus the attached figure shows how would subtract 19 from 37

Draw 37 circles and then use / slashes and cross out 19 of those circles

Donna wants to make trail mix made up of almonds, walnuts, raisins. she wants to mix one part almonds, two part walnuts, and three parts raisins. almonds cost $12 per pound,walnuts cost $9 per pound, and raisins cost $5 per pound. Donna has $15 to spend on the trail mix. determine how many pounds of trail mix she can make.[ only an algebraic solution]

Answers

almons:walnuts:rasins=1:2:3

x=pounds of walnuts
y=pounds of almonds
z=pounds or rasins
2x=y
3x=z
subsitute

12x+9y+5z=15
12x+9(2x)+5(3x)=15
12x+18x+15x=15
45x=15
divide by 45
x=1/3
so
1/3 pound of walnuts
2x=y
2(1/3)=y=2/3
2/3 pounds of almonds
3x=z
3(1/3)=z
1=z
1 pound of rasins

1/3 pound walnuts
2/3 pound almonds
1 pound rasins
