Theo bought 2 hot dogs and two drinks for $4.00. At the same concession stand, Vicky bought 3 hot dogs and a drink for $4.50. Write a system of equations and find what is the price of a hot dog concession stand?
Answers
Answer:
The hot dog are $2.63
Step-by-step explanation:
Hot Dogs = H
Drinks = D
2H + 2D = 4
Divide both sides by 2
H + D = 2
Subtract D from either side
H = 2 -D
3H + D = 4.50
Plug in 2 - D for H
3(2- D ) + D = 4.50
6 - 3D + D = 4.50
6 - 4D = 4.50
Add 6 to either side
-4D = 10.50
Divide either side by -4
D = -2 . 625

All real numbers are solutions
Step-by-step explanation:
Let's solve your equation step-by-step.
−2(2x+3)=−4(x+1)−2
Step 1: Simplify both sides of the equation.
−2(2x+3)=−4(x+1)−2
(−2)(2x)+(−2)(3)=(−4)(x)+(−4)(1)+−2(Distribute)
−4x+−6=−4x+−4+−2
−4x−6=(−4x)+(−4+−2)(Combine Like Terms)
−4x−6=−4x+−6
−4x−6=−4x−6
Step 2: Add 4x to both sides.
−4x−6+4x=−4x−6+4x
−6=−6
Step 3: Add 6 to both sides.
−6+6=−6+6
0=0
Answer:
All real numbers are solutions.

Answers
Answer:
45
Step-by-step explanation:
360/8 = 45
The required angle of the rotation is 45°.
Angle of rotation is to be determined. Each spin represent degree of rotations.
The angle can be defined as the one line inclined over another line.
Total number of spines = 8
The angle of rotation = 360/8
= 45°
Thus, the required angle of the rotation is 45°.

can you answer it. please
Answers
Answer:
5x + 10 + 55 = 90
5x = 90 -55 - 10
5x = 90 - 65
5x = 25
5x ÷ 5 = 25 ÷ 5
x = 5
Answer:
x=5
Step-by-step explanation:
If you replace the x in (5x+10)º
(5x+10)º
[5(5)+10]º
[25+10]º
= 35º
Combine the sums for angles M and R
55º+35º
=90º
Therefore, the answer is x=5.

Which expression shows 7+21 written as a product of two factors?
(A)3(1+7)
(B)3(3+7)
(C)7(3+3)
(D)7(1+3)
Answers
Expressing or writing 7+21 as a product of two factors requires the application of Distributive Property
The expression that shows 7+21 written as a product of two factors is
7(1 + 3).
To solve the above question, we apply the Distributive property.This is expressed as:a (b + c) = ab + ac
Where
a is the common factor
We are given the expression:
7 + 21
Splitting this into two factors using the distributive property
7 + 21
The common factor for 7 and 21 is 7
Hence, by factorising we have:
7 + 21 = 7(1 + 3)
Therefore, the expression that shows 7+21 written as a product of two factors is :
7(1 + 3)
The correct option is D

Step-by-step explanation:
[tex]\boxed{Hey~There!}[/tex]
__________________________________________________________
[tex]\boxed{Simplify~each~radical:}[/tex]
1.) [tex]\sqrt{72}[/tex]:
Factor [tex]72[/tex] into its prime factors :[tex]72 = 23 * 32[/tex]
To simplify a square root, we extract factors which are squares, factors that are raised to an even exponent. Factors which will be extracted are:[tex]36 = 22 * 32[/tex]
Factors which will remain inside the root are:[tex]2 = 2[/tex]
To complete the simplification we take the square root of the factors which are to be extracted. We do this by dividing their exponents by [tex]2[/tex]:[tex]6 = 2 * 3[/tex]
[tex]\boxed{The~answer~is: 6\sqrt{2}}[/tex]
2.) [tex]\sqrt{20}[/tex]:
Factor [tex]20[/tex] into its prime factors :[tex]20 = 22 * 5[/tex]
To simplify a square root, we extract factors which are squares, factors that are raised to an even exponent. Factors which will be extracted are:[tex]4 = 22[/tex]
Factors which will remain inside the root are:[tex]5 = 5[/tex]
To complete the simplification we take the square root of the factors which are to be extracted. We do this by dividing their exponents by [tex]2[/tex]:[tex]2 = 2[/tex]
[tex]\boxed{The~answer~is: 2\sqrt{5}}[/tex]
3.) [tex]\sqrt{42}[/tex]:
Factor [tex]42[/tex] into its prime factors :[tex]42 = 2 * 3 * 7[/tex]
To simplify a square root, we extract factors which are squares, factors that are raised to an even exponent. In our case however, all the factors are only raised to the first power and this means that the square root can not be simplified .[tex]\boxed{The~answer~is: \sqrt{42} }[/tex]
4.) [tex]2\sqrt{12}[/tex]:
Factor [tex]12[/tex] into its prime factors :[tex]12 = 22 * 3[/tex]
To simplify a square root, we extract factors which are squares, factors that are raised to an even exponent. Factors which will be extracted are:[tex]4 = 22[/tex]
Factors which will remain inside the root are:[tex]3 = 3[/tex]
To complete the simplification we take the square root of the factors which are to be extracted. We do this by dividing their exponents by [tex]2[/tex]:[tex]2 = 2[/tex]
[tex]\boxed{The~answer~is: 4\sqrt{3} }[/tex]
5.) [tex]3\sqrt{75}[/tex]:
Factor [tex]75[/tex] into its prime factors :[tex]75 = 3 * 52[/tex]
To simplify a square root, we extract factors which are squares, factors that are raised to an even exponent. Factors which will be extracted are:[tex]25 = 52[/tex]
Factors which will remain inside the root are:[tex]3 = 3[/tex]
To complete the simplification we take the square root of the factors which are to be extracted. We do this by dividing their exponents by [tex]2[/tex]:[tex]5 = 5[/tex]
[tex]\boxed{The~answer~is: 15\sqrt{3}}[/tex]
6.) [tex]-2\sqrt{18}[/tex]:
Factor [tex]18[/tex] into its prime factors :[tex]18 = 2 * 32[/tex]
To simplify a square root, we extract factors which are squares, factors that are raised to an even exponent. Factors which will be extracted are:[tex]9 = 32[/tex]
Factors which will remain inside the root are:[tex]2 = 2[/tex]
To complete the simplification we take the square root of the factors which are to be extracted. We do this by dividing their exponents by [tex]2[/tex]:[tex]3 = 3[/tex]
