So for this you need to set the two equations equal to each other. 20+.05x=10+.07x then solve. Subtract .05 from both sides and get 20=10+.02x. Then subtract 10 from the other side and get 10=.02x Isolate x by dividing 10 by .02. This leaves you with the answer of 500 texts.
Answer:
<em>4√5</em>
Step-by-step explanation:
The length of the radius of the circle will be the distance between the two coordinates. Using the formula:
D = √(x₂-x₁)²+(y₂-y₁)²
Given the coordinates (-4‚-2) and (-8‚-10)
R = √(-8-(-4))²+(-10-(-2))²
R = √(-4)²+(-8)²
R = √16+64
R = √80
R = √16*5
R = 4√5
<em>Hence the length of the radius of this circle is 4√5</em>
Answer:
Step-by-step explanation:
t22 = a + (n- 1)d
t22 = 3 + 21*4
t22 = 3 + 84
t22 = 87
