Answer:
Step-by-step explanation:
The general equation for a direct variation is y = k*x
So your first step (usually) is to find k
y = k x
when x = 4
then y = 50
- y = k*x
- 50 = k * 4 Divide by 4
- 50 / 4 = k*4/4
- 12.5 = k
Now you can find the value of y when x = 2
- y = k*x
- k = 12.5
- x = 2
- y = ?
y = 12.5 * 2
y = 25
Answer:
6000 miles
Step-by-step explanation:
1 in = 1500 miles
4 in = ___ miles
We simply just multiply 1500 and 4
1500 x 4 = 6000
4 in = 6000 miles
Answer:
<em>Let the dryer cost x.</em>
<em>Then, the washer costs (x+87)</em>
<em> </em>
<em>Together, they cost (x) + (x+87) = 787</em>
<em> 2x+87 = 787</em>
<em> 2x = 700 [subtract 97 from both sides]</em>
<em> x = 350 [divide both sides by 2]</em>
<em> </em>
<em>The dryer cost $350.</em>
<em> </em>
<em>Check: The washer cost $437. Together, they cost $787 [good to check, right?]</em>

B. <span>sometimes
is the right answer
</span> <span>Any two angles which add up to 90 degrees are complementary.</span>
A third are spotted so that would mean 2/3 are not spotted so if you take 1200 divide it by 3 and then multiply it by 2 you get 800 which is your answer
