Answer:
45
Step-by-step explanation:
OK, first we turn the variables into into the actual values:
The equation will look like this:
(2)5 + (-5)(-7)
Now its easier to solve! Lets solve (2)5!
2 * 5 = 10
The equation looks like:
10 + (-5)(-7)
We will also solve (-5)(-7). Remember that a negative number times a negative number is positive!
-5 * -7 = 35
Lets finish the rest:
10 + 35 = 45.
Hope this is correct and have a nice day!
A = 6
B = 9
C = 15
D = ?
From A to B, 6 + 3 = 9
From B to C, 9 + 6 = 15
From C to D, 9 + x = ?
The first time, you added 3, for the second time, you added three to the three you are adding, making it 6. So for x, x = 6 + 3, which = 9
9 + 9 = 18
D = 18 should be your answer
hope this helps
Answer:
x = -8
Step-by-step explanation:
The input value other than 7 for which g( x ) = 4
x = -8
Answer:
16.66
Step-by-step explanation:
1) eliminate constant first by performing the opposite operation:
0.24a+0.5-0.5=4.5-0.5
0.24a=4.0
divide both sides by 0.24
a=16.66
Answer:
Correct answer: adult tickets x = 72
Step-by-step explanation:
Given:
x = ? number of the adult tickets
y = ? number of the senior tickets
12$ adult ticket price
8$ senior ticket price
We will solve this problem using a system of two equations with two variables
x + y = 98 we will multiply whole equation with number - 2 and get:
- 2 x - 2 y = - 196
12 x + 8 y = 1072 we will divide the whole equation by the number 4 and get:
3 x + 2 y = 268
- 2 x - 2 y = - 196
we will now add the first equation to the second and get:
3 x - 2 x = 268 - 196
x = 72
x + y = 98 ⇒ 72 + y = 98 ⇒ y = 98 - 72 = 26
y = 26
God is with you!!!
