Let x = cost of one t-shirt
Let y = cost of one sweatshirt
Jayden: 9x + 3y = $420
Carson: x + 6y = $296. Multiply Jayden's equation by -2
Jayden: -18x - 6y = $-840
Carson: x + 6y = $296. Add the equations together to eliminate variable y.
New equation: -17x = $-544. Divide each side by -17.
x = $32. Plug this value into one of the original equations.
32 + 6y = $296. Subtract 32 from each side.
6y = 264. Divide each side by 6.
y = 44.
Plug both your x and y value into one of the equations to ensure they're correct.
9(32) + 3(44) = 420
420 = 420.
x = 32
y = 44.
To solve this problem we have to find what 85% of 40 is, and then add that value to 40.
40 * 0.85 = 34
34 + 40 = 74
74 is the result when 40 is increased by 85%.
I would say no because the number 1 at any power would be 1 for example 1 to the power of 3 is 1 x 1 x 1 which would still be one
(10x + 4) + (5x-4) ≈ 180
solve for x and you get x≈12
plug 12 in to 5x-4 and you get 56
Answer:
82*
Step-by-step explanation:
10x+8 = 12x-10
18 = 2x
X=9
Angle 1 = 98*
Angle 3 = 98*
180 - 98* = 82*
