Answer:
A
Step-by-step explanation:
For test A, the unit rate is 30 words per minute divided by 4 minutes, or 7.5 words per minute.
Unit rate = 78 words/15 minutes = 5.2 words per minute for test B.
The unit rate for test C is 99 words/22 minutes, or 4.5 words per minute.
So for this problem the equation would be y=15x+1200
x, being the number of hours the store clerk works is 60. You then multiply 15x60 and get 900. 900 hours + 1200 rent is 2100 total. So A. :)
If $4.59 = 5.4 peanuts
$x = 7. 8 peanuts
Cross multiply and you get:
5.4x = (4.59)(7.8)
x = ((4.59)(7.8)) / 5.4
x = $6.63
m∠X + m∠Y < 90° is true.
<h3>How to solve it?</h3>
XYZ is a triangle.
We have to find the option that is true about △XYZ.
By angle sum property of a triangle,
The sum of all the interior angles of a triangle is always equal to 180°.
So, ∠X + ∠Y + ∠Z = 180°
Given, m∠Z > m∠X + m∠Y.
This implies that ∠Z is greater than the sum of the angles ∠X and ∠Y.
so, ∠X + ∠Y must be less than 90°.
Hence, we can say that ∠X + ∠Y < 90°

Answer:
a = 7
Step-by-step explanation:
a - 17 = -10
Add 17 to each side
a - 17+17 = -10+17
a = 7
