B. 144 in2
C. 420 in2
D. 288 in2
Answers
the triangles' areas are:
6 • 16 = 96
the rectangles on the sides have areas of:
10 • 9 • 2 = 180
and the base rectangle has an area of
16 • 9 = 144
the surface area is 96+180+144 which is 420 in2.

Given equation is y=2x+7 and
Let's simplify the 2nd equation before we can start graph so that calculation will be easy
multiply both sides by 2 to cancel out fractions
y=2x+7
which is exactly same as the first equatoin so graph of both will be exactly same and solution will be infinitely many solutions.
y=2x+7 has y-intercept 7 so first point will be (0,7). Slope is 2 so rise 2 unit up then 1 right and graph the new point.

so they bought 5 lunches: 5x
deserts are cheaper than lunches; they cost:
x-5.25
So together they paid:
5x+3*(x-5.25)=60.25
(we know how much they paid, so we can make an equation)
Let's remove the bracket:
5x+3*x-15.75=60.25
8x-15.75=60.25//we add 15.75 to both sides:
8x=76
and divide by 8:
x=9.5
So each lunch costs 9.5 dollars!
What is the original price of the board game, before tax?
Answers
Answer:
$27.99
Step-by-step explanation:
100/7.25% sales tax = 1.54 x 13.7931034483 = 21.2413793104
We did the example to prove that when accounting for fixed tax the price will be higher once tax of same percentage amount applied.
This proves 1.75% more in interest is a far lower price ($6.56 less)
Where we compare the price set for 5.5 as asked in the question.
100/5.5% sales tax = 1.54 x 18.181818181 =27.9999999987
=$27.99
We do not round up or down repeating numbers.
