Since angles A and C are equivalent, then angles B and D must also be equivalent. So if
angle B = angle D then...
7x + 15 = 8x
Now we just solve for x
7x + 15 = 8x
15 = 8x - 7x
15 = x
We Can check to see if it is correct by substituting 15 in for x in the equation..
7x + 15 = 8x
7 (15)+15 = 8 (15)
105 +15 = 120
120 = 120
It checks! angles B and D = 120 degrees
Answer:
y= -4
Step-by-step explanation:
The blue line is y=2 and the red is y= -4.
Scale 1: 250,000 literally means for 1cm you calculated on the map it is magnified by 250,000 times. So if that road is 4-6cm, you just multiply it by 250,000 times and you get 1,150,000 cm.
Since you wanted to be in Km. the 100 cm is 1 meter and 1000 meters is 1 km. Therefore, 1,150,000/ 100 x 1000 = 11.5 km . Answer: 11.5 km.
The standard form of an equation is Ax + By = C. In this kind of equation, x and y are variables and A, B, and C are integers. When we shift the variable terms to the left side of the equation and everything else to the right side, we get . This equation is now in standard form.
the standard form of your equation is
5y+10x=−2
