Step-by-step explanation:
1. x-7
A number decreased by seven.
2. y+9
A number increased by nine.
3. 6m/8
The product of six and a number, divided by eight.
4. 3y+5 =20
The product of three and a number increased by five is equal to twenty.
5. 2(x+8)= 23
The product of two and a number increased by eight is equal to twenty-three.
Answer:
2
Step-by-step explanation:
13x2=26
14x3=42
Greatest common Factor of 26 and 42 is 2
Realize the tangent function has a period of 180°, so when your calculator (or memory) tells you
.. θ = arctan(-1)
.. θ = -45°
you can translate that value into the desired range by adding multiples of 180° to get the two solutions ...
.. θ = 135°
.. θ = 315°
The answer is 3:11 and 3 to 11
