Answer:
By evaluating correctly the answer is 422910.
Step-by-step explanation:
Given:
42.291 divided by 10^-4.
Now, evaluating:
Now, we will change the exponent from negative to positive.
Now, we change the division to multiplication.
And, we will break the exponent.
Therefore, by evaluating correctly the answer is 422910.
16x - 3 + 5x + 2 = 72
21x - 1 = 72
21x = 72+1
21x = 73
x = 73/21
x ≈ 3.48
Distance from Diego's house to the restaurant:
16x - 3 = 16 * 3.48 - 3 ≈ 52.6 miles
Distance from Anya's house to the restaurant:
5x + 2 = 5 * 3.48 + 2 ≈ 19.4 miles
52.6 ≠ 19.4 ⇒ <span>Diego was wrong.</span>
Answer:
x=16
y=23
Step-by-step explanation:
angle (4x+4) and angle (7x-44) are alternate exterior angles which are equal, so we can set up an equation like this to find x:
4x+4=7x−44
calculate it then you'll get x=16
for the next one I'm not really sure how to explain since they are not labeled but,.. since we have the measure 39 we can figure out by using the pairs 'interior angles on the same side of a transversal' and 'vertical angles' that it's equal to 141, so to find y we use the equation
8y-43=141
calculate it and you'll get y=23
