Answer:
91
Step-by-step explanation:
the formula for a triangle is base x height divided by 2
so the base is 13 and the height is 14
multiply 13 and 14 then divide by 2
13 x 14 = 182/2= 91
-2log_5 7x = log_5 2
log_5[1/(7x)^2] = log_5 2
log_5(1/49x^2) = log_5 2
log_5(1 - 49x^2) = log_5 2
1 - 49x^2 = 2
You finish.
Let # of child tickets = c
# of adult tickets = 3c
3c (8.30) + c (5.20) = 1173.90
24.9c + 5.2c = 1173.90
30.1c=1173.90
c=39 tickets
3c=39x3= 117 tickets
Therefore, 39 child tickets and 117 adult tickets were sold on monday, thus, a total of 156 tickets were sold.
Answer:
2x + 5y = -15 OR 2x + 5y + 15 = 0 Not sure they want it equal to zero
Step-by-step explanation:
y + 7 = -2/5(x - 10)
y + 7 = -2/5 x + 4
2/5x + y =-3
5(2/5 x + y = - 3)
2x + 5y = - 15
OR
2x + 5y + 15 = 0
Answer:
50. ☺️☺️
Step-by-step explanation:
I'm going to assume you need this inequality solved.
First, write it as numbers, not words.
7/10n + 14 < 49
where "n" is the unknown number.
Second, if I were you, I'd change that fraction into a decimal, as it'll make life easier later on.
7/10 = 0.7
Now, solve it like you would any other equation.
0.7n + 14 < 49
0.7n +14 - 14 < 49 - 14
0.7n < 35
0.7n ÷ 0.7 < 35 ÷ 0.7
n < 50
The answer is n < 50
