Mr. Alvarado bought a total of 20 pounds of grass seed at the nursery for $168. He paid $9 per pound for Kentucky blue grass and

Nuetrik [128]

Answer:

K+T=20

$9K + $6T = $168

K is the Kentucky blue grass in pounds

T is the Tall fescue in pounds

Step-by-step explanation:

You can start with the first equation. We don't know the exact amounts of each but we know that there was a total of 20 pounds, and there were 2 types of grass seeds, so we can get that the amount of pounds of Kentucky blue grass(K) and the pounds of Tal Fescue(T) has a sum of 20.

K + T = 20

For the second equation we know that there is a sum of $168 so we'll start with that. Then, we know he paid $9 per pound of K so $9* the value of K is the amount paid for Kentucky blue grass total. This can be represented as 9K. We do the same for T, 6T. Since the sum of the cost of $9T and $6K must be $168 we can write this as:

$9K + $6T = $168

If i have 2 c's 2 A's 3 b's and 1 d what is my gpa and would i be able to pass 8th grade

IgorC [24]

A= 4 points
B= 3 points
C= 2 points
D= 1 point
F= 0 points

So you add 2+2+4+4+3+3+3+1
Which equals 22
Now divide 22 by 8
You get 2.75
So yes with a 2.75 gpa you should pass 8th grade as most schools require nothing less than a 2.0

A clown bought 5 bags of round balloons with 24 balloons in each bag. The clown also bought 3 bags of long balloons with 36 ball

dimaraw [331]

Answer:

247 blown up balloon left

Step-by-step explanation:

5 bags of round balloon with 24 balloon in each bag =

= 5 x 24 = 120 round balloons

3 bags of long balloon with 36 balloon in each bag =

= 3 x 36 = 108 long balloons

Part 1 Answer

120 round balloons - 108 long balloon = 12 balloons

therefore the clown bought 12 more round balloon than long balloon

Part 2

3 bags of heart-shaped balloons with 14 balloons in each bag =

= 3 x 14= 42 heart-shaped balloons

All the balloons were blown which equals

120 round balloons + 108 long balloons + 42 heart-shaped balloons =

= 270 balloons

23 balloons out of the 270 balloons burst which equals

270 blown balloon - 23 burst balloon = 247 blown-up balloons left

so,

247 blown-up balloons were left
