Answer:
t = 14
Step-by-step explanation:
log (7t + 2) = 2
Raise each side to the power of 10
10 ^log (7t + 2) =10^ 2
7t+2 = 100
Subtract 2 from each side
7t+2-2 = 100-2
7t = 98
Divide each side by 7
7t/7 = 98/7
t = 14
Hello!
First we have to define a variable.
Let x stand for the price of a granola bar
Then we have to make our equation
1250x + 25 = 800
This is the equation because the price for all the granola bars and delivery was $800
Now we solve it
Subtract 25 from both sides
1250x = 775
divide 1250 from both sides
x = 0.62
The cost for a granola bar is $0.62 or 62 cents
Hope this helps!
Answer:
39°
Step-by-step explanation:
For a straight line, the sum of angle is 180°
At the point where we have the 107°, the inner angle in the triangle will be 180-107=73°
68° is alternate angle to the inner angle in the triangle
Since the sum of angles in a triangle are 180°, then angle x will be
X=180-73-68=39°
Therefore, missing angle is 39°
Answer:
Right triangle since it has a right angle = 90°
