Mal works at a photo gallery. He charges $50 for a large photo and $40 for a large frame. Sales tax is 5%. How much total tax will a customer pay on both?
Answer the questions to show how to write and simplify expressions that represent the problem.
1. One way to calculate the total tax is 0.05(50 + 40). Use the order of operations to evaluate this expression.
2. Use the distributive property to expand 0.05(50 + 40).
3. Find the total tax using the expanded expression. Did you get the same answer as you did by evaluating the original expression?
4. Which expression, the original expression or the expanded expression, involves finding the total cost first, then calculating the tax on that total?
The cost of large photo after sales tax is $94.5.
Given that, Mal charges $50 for a large photo and $40 for a large frame. Sales tax is 5%.
Total cost of large photo = 50+40
= $90
Sales tax on large photo
= 5% of 90
= 5/100 ×90
= 0.05×90
= 4.5
Cost of large photo after tax = 90+4.5
= $94.5
Therefore, the cost of large photo after sales tax is $94.5.

Which equation has no solution?
-5+8x-9=3(x+3)
-2(6-3x)=-12+6x
6-2(3-2x)=-4(3-x)
-(4x+9)=2x-3(2x+3)
Answer:
-2(6-3x)=-12+6x

What is the length of JN? Please help!
Answer:
Answer is 6 and 2/3. That’s it
Step-by-step explanation:
The length of JN of the second triangle is [tex]6\frac{2}{3}[/tex].
Triangle SimilarityWhat is similarity of triangles?If two triangles have an equal number of corresponding sides and an equal number of corresponding angles, then they are comparable.
Similar figures are described as items with the same shape but varying sizes, such as two or more figures.
Calculation for the length JN:As the two triangles BTL and PJN are similar because the corresponding two angles are given equal in the question.
Thus, the ratios of the side are equal.
[tex]\frac{BT}{JP} = \frac{LT}{JN}[/tex]
[tex]\frac{6}{8} =\frac{5}{JN}[/tex]
[tex]JN =\frac{20}{3}[/tex]
[tex]JN= 6\frac{2}{3}[/tex]
Therefore, the length JN of the triangle comes out to be [tex]6\frac{2}{3}[/tex].

Answer:
Surface Area of the box is 190" or in.
Step-by-step explanation:
We start by determining the surface area formula for the box, which is a rectangular prism:
S = 2(l*w+w*h+l*h), where S = surface area of rectangular prism, l = length, w = width, and h = height.
Since length = 7", width = 2", and height = 9", we can substitute the information given into the formula above.
S = 2((7*2)+(2*9)+(7*9))
= 2(14+18+63)
= 2(95)
= 190"
Surface Area of the box is 190" or in.

Liza is designing a calendar as a fund-raising project for Math Class. The cost of printing
is 5000php, plus 150php per calendar. Write an equation in slope-intercept form that
models the total cost of printing the calendars.
Answer: y = 150x+5000
Step-by-step explanation:
Equation in slope-intercept form:
y= mx+c , where x= independent variable , y= dependent variable, m= slope , c= y-intercept.
Given: The cost of printing is 5000php, plus 150 php per calendar.
If x= Number of calendar and y= Cost of x calendars.
Then, m= 150 , c= 5000
Equation becomes
y = 150x+5000
