Answer:
Chips= $1.79
Soda= $1.12
chips: $1.79
soda: $1.12
Step-by-step explanation:
x = chips cost
y = soda cost
4x + 3y = 10.52
3x + 2y = 7.61
i used the elimination method by multiplying the first equation by -2
and the second equation by 3
-8x - 6y = 21.04
9x + 6y = 22.83
x = 1.79
solve for 'y':
3(1.79) + 2y = 7.61
5.37 + 2y = 7.61
2y = 2.24
y = 1.12
50 cm^2
area of rectangle = base * height
5 * 7 = 35
area of triangle = base * height / 2
5 * 4 = 20/2 = 10
5 * 2 = 10/2 = 5
add them all up
35 + 5 + 10 = 50 cm^2
4√34
Let the unknown side be y
y^2 = 20^2 + 12^2
y^2 = 400 + 144
y^2 = 544
Take the square root of both side
y = √544
y = √(16x34)
y = √16 x √34
y = 4√34
120÷5=24 / 24×4=96 / 96+24=120
