Answer:
B
Step-by-step explanation:
<span>equation 1/5x-2/3 y = 30, when y = 15?
so
</span><span> 1/5x-2/3 (15) = 30
1/5x - 10 = 30
1/5x = 40
x = 40(5)
x = 200
answer
</span><span>D.200</span>
He spent $14.44 more on groceries this week than last week
<h3>How to determine the additional amount that was spent this week?</h3>
From the question, the given parameters are
Amount spent last week = $58.34
Amount spent this week = $72.78
The additional amount that was spent at the grocery store this week is calculated by subtracting the amount spent this week from the amount spent last week
This is represented as
Additional amount = Amount spent this week - Amount spent last week
Substitute the known values in the above equation
So, we have
Additional amount = 72.78 - 58.34
Evaluate the difference
Additional amount = 14.44
Hence, an additional of $14.44 was this week

Use the cross multiplication method. 768.57 over 41.1= x/1 768.57 times 1=768.57 41.1 times x=41.1x 768.57/41.1=x x=18.7 18.7mph
That's the cosine x. The cosine of 0 is 1, so that's how you can tell. The sin of 0 is 0, so that's where the sin graph goes through the y axis
