Hey You!
132*42% = 55.44
132 - 55.44 = 76.56
So, the Millers paid $55.44 for gas and $76.56 for electricity.
Answer:number of cupcakes sold is 13
Number of cookies sold is 27
Step-by-step explanation:
Let x represent the number of cupcakes that Jane sold.
Let y represent the number of cookies that Jane sold.
Each cupcake sold for $2.25 and each cookie sold for $0.50. At the end of the day, Jean had sold $42.75 worth of cookies and cupcakes.
This means that
2.25x + 0.5y = 42.75 - - - - - - - - - -1
she sold 40 cupcakes and cookies combined, it means that
x + y = 40
Substituting x = 40 - y into equation 1, it becomes
2.25(40 - y) + 0.5y = 42.75
90 - 2.25y + 0.5y = 42.75
- 2.25y + 0.5y = 42.75 - 90
- 1.75y = - 47.25
y = - 47.35/-1.75
y = 27
x = 40 - y
x = 40-27 = 13
.
Answer:
![\frac{2}{5}+\frac{1}{3}=\frac{6}{15}+\frac{5}{15}=\frac{11}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B5%7D%2B%5Cfrac%7B1%7D%7B3%7D%3D%5Cfrac%7B6%7D%7B15%7D%2B%5Cfrac%7B5%7D%7B15%7D%3D%5Cfrac%7B11%7D%7B15%7D)
Explanation:
The given addition exercise is:
![\frac{2}{5}+\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B5%7D%2B%5Cfrac%7B1%7D%7B3%7D)
The LCM of the denominator (5 and 3) = 15
Multiply 2/5 by 3/3
![\frac{2}{5}=\frac{2\times3}{5\times3}=\frac{6}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B5%7D%3D%5Cfrac%7B2%5Ctimes3%7D%7B5%5Ctimes3%7D%3D%5Cfrac%7B6%7D%7B15%7D)
Multiply 1/3 by 5/5
![\frac{1}{3}=\frac{1\times5}{3\times5}=\frac{5}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%3D%5Cfrac%7B1%5Ctimes5%7D%7B3%5Ctimes5%7D%3D%5Cfrac%7B5%7D%7B15%7D)
The addition becomes
![\frac{6}{15}+\frac{5}{15}=\frac{11}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B15%7D%2B%5Cfrac%7B5%7D%7B15%7D%3D%5Cfrac%7B11%7D%7B15%7D)
Therefore, we can fill in the vacant boxes as shown below:
<u>Finding x:</u>
We know that the diagonals of a rhombus bisect its angles
So, since US is a diagonal of the given rhombus:
∠RUS = ∠TUS
10x - 23 = 3x + 19 [replacing the given values of the angles]
7x - 23 = 19 [subtracting 3x from both sides]
7x = 42 [adding 23 on both sides]
x = 6 [dividing both sides by 7]
<u>Finding ∠RUT:</u>
We can see that:
∠RUT = ∠RUS + ∠TUS
<em>Since we are given the values of ∠RUS and ∠TUS:</em>
∠RUT = (10x - 23) + (3x + 19)
∠RUT = 13x - 4
<em>We know that x = 6:</em>
∠RUT = 13(6)- 4
∠RUT = 74°
