Answer: it would cost a total of $194
Step-by-step explanation:
A ticket to a movie theatre for a student is $7. The cost for an adult is $2 more than for a student.
If student ticket costs $x, adult ticket would cost x + 2
This means that the cost for an adult is
7 + 2 = $9
The cost of 13 adult tickets to the movie theatre would be
13 × 9 = $117.
The cost of 11 student tickets to the movie theatre would be
11 × 7 = $77
Total cost of 13 adult tickets and 11 student tickets would be
117 + 77 = $194
Answer:
Using the Angle Addition Postulate, 20 + m∠DBC = 80. So, m∠DBC = 60° using the subtraction property of equality.
Step-by-step explanation:
If point D is the interior of angle ABC, then the angle addition postulate theory states that the sum of angle ABD and angle DBC is equals to angle ABC. The angle addition postulate is used to measure the resulting angle from two angles placed side by side.
From the attached image, ∠ABD and ∠DBC are placed side by side to form ∠ABC. Given that m∠ABD = 20° and m∠ABC = 80°
Hence, using angle addition postulate:
m∠ABD + m∠DBC = m∠ABC
20 + m∠DBC = 80
subtracting 20 from both sides (subtraction property of equality)
m∠DBC = 80 - 20
m∠DBC = 60°
Answer:
Weight of the solution = 250 grams
Step-by-step explanation:
1) Consider the weight of solution as x grams.
32 % solution = 80 grams salt
32% of x = 80
(32/100)*x = 80
Solving for x:
x = (80*100) / 32
x = 250 grams
Answer:
4. Yes 5.No 6. No
Step-by-step explanation:
To be short,a linear equation has a coefficient of only 1 degree.
If the degree is over 1 it isn't a linear equation.
4 is the linear equation since it x value 7x has a degree of 1.
5 isn't becuase it's x value has a degree of 5
6 isn't becuase it degree is 4.
