Find the values of x and y. Please help

Mathematics
1 answer:
weeeeeb [17]3 years ago
5 0

Answer:

x= 61 degrees

y= 61 degrees

Step-by-step explanation:

A triangle is equal to 180 degrees. We already know one corner is 58 degrees, and 180-58=122 remaining degrees. We also know the 2 remaining corners are equalivent, so we can do 122/2 which gives us 61 degrees for x and y. :)

STatiana [176]

Sum of interior angles of a △ = 180°

∴ ∠T + ∠V + ∠U = 180°

⇒ 37° + 63° + X° = 180°

⇒ X° + 100 = 180°

⇒ X° = 180° - 100°

⇒ X° = 80° (D).

Solve 5x+4y=-30<br> 3x-9y=-18<br> Solve using the elimination method
jenyasd209 [6]

Answer:

  (x, y) = (-6, 0)

Step-by-step explanation:

The y-coefficients have opposite signs, so we can eliminate y-terms by multiplying both equations by a positive number and adding the results.

9 times the first equation plus 4 times the second gives ...

  9(5x +4y) +4(3x -9y) = 9(-30) +4(-18)

  45x +36y +12x -36y = -270 -72 . . . . eliminate parentheses

  57x = -342 . . . . . collect terms

  x = -6 . . . . . . . divide by the coefficient of x

__

Substituting into the first equation gives ...

  5(-6) +4y = -30

  4y = 0 . . . . . . . . . add 30

  y = 0

The solution is (x, y) = (-6, 0).

Susan and John are buying cold drinks for a neighborhood picnic. Each person is
givi [52]

Answer:

Susan has suggested a correct method to calculate the amount of money

Step-by-step explanation:

Here we must check what each person is calculating. First, we consider Susan's method. She has suggested that we multiply the cost per soda, that is dollars/soda by the number of sodas required, we get the total cost.

Assuming that 18 sodas are required and each costs $0.20, the total cost according to Susan is $3.60.

John suggests we divide the cost of a 12 pack of soda by the number of sodas required. Considering a 12 pack of soda costs $12 and the same amount of sodas, 18, are required, we get that each soda costs $0.66.

Looking at these answers, we see that Susan has suggested a correct method to calculate the amount of money needed to buy a number of sodas. John has suggested the amount each person would have to contribute if everyone at the party was trying to buy a 12-pack of soda; regardless of whether more or less than a 12-pack is required.
