Answer:
a =1
Step-by-step explanation:
2(a+7)-7=9
Add 7 to each side
2(a+7)-7+7=9+7
2(a+7)=16
Divide by 2
a+7 = 16/2
a +7 = 8
Subtract 7
a+7-7 = 8-7
a = 1
The measures of the angles are 30, 60 and 90 degrees.
Explanation:
I assume the question should read "the measures of the ANGLES of the triangle are in the ratio 2:4:6.
If the angles are in the proportion 2:4:6, the measures of the angles have the same scale factor
x
. And, the sum of the measures of the angles of a triangle is
180
.

Number of stocks held = 30
Price at which each shares of Lofty Cheese Company bought = 20 1/4
= (81/4) dollars
Price at which each shares of Lofty Cheese Company sold = 25 1/4
= (101/4) dollars
Amount of profit made per share of Lofty Cheese Company = [(101/4 - (81/4)] dollars
= (20/4) dollars
= 5 dollars
Amount of profit made for 30 shares of Lofty Cheese Company = (30 * 5) dollars
= 150 dollars.
So you will make a profit of $150.The correct option in regards to the question given is option "C".
Answer:
The fourth term in the sequence is equal to the third term plus the common difference, or 16+3=19- last choice
E[y]=∑yp(y)=4(0.176)+(−1)(0.824) =−.12 dollar, so In one play the player is expected to lose 12% of a dollar.
