Answer:
B.70
Step-by-step explanation:
For one or two angles are complementary angle(s), they have to equal 90°.
So, we need to find the larger angle, but what about the other?
Let x be the other angle and y be the angle we are looking for
x + y = 90
Lets look for x first, since one angle is ten less than four times the angle we are looking for or visa versa, we must:
y = 4x - 10
For an exchange, lets take out the y variable for another x variable:
So now we should have x + 4x - 10 = 90
Combine like terms and do cross equation :
x + 4x -10 = 90
5x - 10 = 90
Add 10 to both sides:
5x = 100
100/5 = 20
So <u><em>x=20</em></u>
<u><em></em></u>
Now for y which is what we are looking for,
y = 4x - 10
Since x is 20, plug it in
y = 80 - 10
y=70 is our larger angle
To find the answer you need to find the common factor of numbers 25 and 60
25,50,75,100,125,150,175,200,225,250,275,300
60,120,180,240,300
The 300th customer will receive both cards, and a total of $220 and 17 gift cards were given away.
Answer:
Step-by-step explanation:
<h3>#1</h3>
- 15 ⋅ 6 - 2² ⋅ 8 + 4³ =
- 15 ⋅ 6 - 4 · 8 + 64 =
- 90 - 32 + 64 =
- 58 + 64 =
- 122
<h3>#2</h3>
- 2³ + 2² ⋅ 2 + 6 - 2¹ ⋅ 2⁰ - 1 =
- 8 + 4 · 2 + 6 - 2 · 1 - 1 =
- 8 + 8 + 6 - 2 - 1 =
- 22 - 2 - 1 =
- 20 - 1 =
- 19
