X is equal to 64
40 divided by 5/8 is 64
Answer:
<em>UV </em>= 8.9 <em>∠V=</em>30° <em>∠U</em>=60°
Step-by-step explanation:
1. Find the hypotenuse (<em>UV </em>)
8^2+4^2=c^2
64+16=c^2
80=c^2
C= 
or 8.94427191...
2. We know this is a right triangle is a 30, 60, 90 triangle because the sides are not the same. This means ∠V=30° and ∠U=60° The 30 degree angle is opposite of the short leg and the 60 degree angle is opposite of the long leg.
Answer:
n=2
Step-by-step explanation:
4(5n-7)=10+2
1) First, distribute (multiply out 4)
20n-28=10+2
2) Combine like terms (add 10 and 2)
20n-28=12
3) Isolate the variable (Add 28 to 12)
20n=40
4) Isolate the variable (Divide by 20)
n=2
An arithmetic sequence is a sequence with the difference between two consecutive terms constant. The difference is called the common difference. A geometric sequence is a sequence with the ratio between two consecutive terms constant. This ratio is called the common ratio.
A negative plus a negative equals a negative so it's just -17
