11. The cost of a hamburger and a soft drink together is $2.23. The cost of 2 hamburgers and
3 soft drink together is $5.26 What is the cost of a soft drink? What is the cost of a burger?
Answers
Answer:
answer for 10th question is 121
Step-by-step explanation:
2(a+b)+a+b/2+(a+b)^2-4
=2(10)+10/2+(10)^2-4
=20+5+100-4
=125-4
=121
Answer:
10. 121 11. Hamburger = $1.43
Step-by-step explanation:
2(a + b) + (a + b)/2 + (a + b)² - 4
2(10) + (10)/2 + (10)² - 4
20 + 5 + 100 - 4
25 + 100 - 4
125 - 4 = 121
11. Let H = Hamburger and Soft Drink = D
H + D = $2.23
2 H + 3D = $5.26
H + D = $2.23 Solve for D
D = $2.23 - H
2H + 3D = $5.26 Now substitute the value of H into the second equation.
2H + 3($ 2.23 - H) = $5.26
2H + $6.69 - 3H = $5.26
-H + $6.69 = $5.26
-H = - $1.43
H = $1.43

Can someone tell me the answer please
Answers
Answer:
Below.
Step-by-step explanation:
a = 37 degrees ( vertical angle to 37 )
c = 180 - 37 = 143 degrees (adjacent angles add up to 180).
b = 180 - 37 - 109 = 34 degrees (angles in a triangle sum to 180 degrees).
a = 37 degrees
c = 180 - 37 = 143 degrees.
b = 180 - 37 - 109 = 34 degrees

How many solutions are there for the following equation? Why?
8(x + 9) = 72 – 5x
Select the option that correctly answers both questions.
1 There is one solution, because the coefficients of the variables on both sides of the equation are different.
2 There is one solution, because the coefficients of the variables on both sides of the equation are the same.
3 There are no solutions, because the coefficients of the variables on both sides of the equation are different.
4 There are no solutions, because the coefficients of the variables on both sides of the equation are the same.
Answers
Answer:
I think 2? maybe 1.
Step-by-step explanation:
because it becomes 8x+72=72-5x which can then become 3x=0 then x=0/3 and 0/3=0 so x=0

what is [tex]−3.64⋅|5.3|−1.5^3[/tex]
Answers
Answer:
- 22.667
Step-by-step explanation:
1.5^3 = 1.5 x 1.5 x 1.5 = 3.375
- 3.64 ⋅ | 5.3 | - 1.5^3
= ( - 3.64 ⋅ | 5.3 | ) - 1.5^3
= ( - 3.64 ⋅ 5.3 ) - 1.5^3
= ( - 3.64 x 5.3 ) - 1.5^3
= - 19.292 - 3.375
= - 22.667

a) -4+8i
b)-4-8i
c)4+8i
d)4-8i
Answers
Answer:
Step-by-step explanation:
c - d = 7
c = 3 - 8i Substitute into the top equation
3 - 8i - d = 7 Subtract 3 from both sides
- 8i - d = 7 - 3 Combine
-8i - d =4 Add 8i to both sides
-d = 4 + 8i Multiply through by -1
-1*-d = -4 - 8i
d = - 4 - 8i

Which solution makes this equation true?
1. -12
2. -2
Answers
Let’s try x = -12
1/2(-12) - 5 = -6
PEMDAS says to multiply first
1/2 x -12 = -6
So
-6 - 5 = -6
-6 - 5 = -11 not -6 so it’s not that
Now let’s do x = -2
1/2(-2) - 5 = -6
Again, you multiply first
1/2 x -2 = -1
-1 - 5 = -6 so it works

Answers
Answer:
x = -4
Step-by-step explanation:
2x + 34 = 6 - 5x
Subtract 34 from both sides.
2x = -28 - 5x
Add 5x to both sides.
7x = -28
Divide both sides by 7.
x = -4
Proof:
2x + 34 = 6 - 5x
Substitute variable.
2(-4) + 34 = 6 - 5(-4)
Multiply.
-8 + 34 = 6 + 20
Add.
26 = 26
Answer:
x = -4
Step-by-step explanation:
2x+34=6-5x
+5x +34 = 6+5x

Vickie was born on this day in 1981. Including leap years, how many seconds old is Vickie?
Answers
Answer:
Vickie is about 1,256,428,800 seconds old.
Step-by-step explanation:
1 year = about 31,536,000 seconds
2021 - 1981 = 40
39 × 31,536,000 = 1,229,904,000 (total 365-day years in seconds discluding this year)
____________________________________________
Now, add the leap days.
Since 1981, there has been 10 leap years, meaning 10 leap days.
1 leap day = about 86,400 seconds
86,400 × 10 = 864,000 (total leap day seconds)
____________________________________________
Today is 10/24/2021, so it is the 297th day of the year.
1 day = exactly 86,400 seconds
297 × 86,400 = 25,660,800 (total seconds this year)
____________________________________________
Add all values to get the total amount of seconds.
1,229,904,000 + 864,000 + 25,660,800 = 1,256,428,800 (total seconds of how old is Vickie)
