Elimination using multiplication.
3x-5y=14
2x+4y=2

Answers

Answer 1
Answer: 3x - 5y = 14
2x + 4y = 2

We multiply the first equation by 2 and the second equation by 3 to obtain:

6x - 10y = 28
6x + 12y = 6

Subtracting the two equations:

-22y = 22
y = -1

Using this in the first equation:
3x - 5(-1) = 14
x = 3

The solution is:
(3 , -1)

Scott puts some sports in rowhe makes 6 rows with 5 stickers in each row.If he puts the same number of stikers in 5 equal row how many stickers would be in each row? How do you know

Answers

We know that Scott has put 6 rows with 5 stickers each.

The total number of stickers available with Scott = 5*6 = 30 stickers

These 30 stickers are now placed in 5 rows with equal number of stickers in each row.

Number of stickers in each row= Total number of stickers available/number of rows

Number of stickers in each row = 30/5 = 6 stickers

Number of stickers in each row now would be = 6 stickers

I need help with this question

Answers


With all due respect, I'm guessing that you're fine with the question,
but you could use some help on the answer.  Am I right ?

-- The answer has something to do with the total amount the coach spent,
so we'll need to know that amount.   Let's find it now:

(9 chickens) x ($5 each) = $45 for chicken
(15 burgers) x ($6 each) = $90 for burgers

Total amount he spent:  ($45 + $90) = $135 all together  ( nice coach ! )

What part of it was used for the chickens ?
Remember, he spent  $45  for chickens.

   $45 / $135  =  1/3  =  0.33333....  =   ( 33 and 1/3 ) percent

Now I'm wondering ... it doesn't say anywhere in the problem ...
do you think he gave any of that food to the team ?

Which best explains whether or not all isosceles triangles are similar?a.All isosceles triangles are similar. Two angles within each triangle are always congruent.b.All isosceles triangles are similar. The triangle sum theorem states that the sum of the angles in a triangle is 180°. Therefore, the third angle can always be determined. c.All isosceles triangles are not similar. The pair of congruent angles within one triangle is not necessarily congruent to the pair of congruent angles within the other triangle.d.All isosceles triangles are not similar. Given only the vertex angle of an isosceles triangle, there is not enough information to determine the measures of the base angles. Therefore, it is not possible to determine if the base angles of one isosceles triangle are congruent to the base angles of another.
