5x + 2y = 12
-6x - 2y = -14
Add them
-x = -2
x = 2
5x + 2y = 12
(5*2) + 2y = 12
10 + 2y = 12
2y = 2
y = 1
<span>= 49567/1000
</span>rite the decimal number as a fraction
(over 1)
49.567 = 49.567 / 1
Multiplying by 1 to eliminate 3 decimal places
we multiply top and bottom by 3 10's
Numerator (N)
N = 49.567 × 10 × 10 × 10 = 49567
Denominator (D)
D = 1 × 10 × 10 × 10 = 1000
N / D = 49567 / 1000
Simplifying our fraction

Use pythagorean theorem for all of them
a. 3, 4, 5
3^2+4^2?5^2
9+16?25
25=25
right
b. 5, 6, 7
5^2+6^2=7^2
25+36=49
61>49
acute
c. 64+81=144
145>144
acute
hope this helps!
