Solve the system by substitution.
y = 8x – 6
y = 2x
Answers
Answer:
x = 1
y = 2
Step-by-step explanation:
y =8x - 6 ---------------------------------(I)
y = 2x -------------------------------------(II)
substitute y = 2x in equation (I)
2x = 8x - 6
Add 6 to both sides
2x + 6 = 8x
Subtract 2x from both sides
6 = 8x - 2x
6 = 6x
Divide both sides by 6
6/6 = x
x = 1
Substitute x = 1 in equation (II)
y = 2*1
y = 2

Tom buys a hat for $13.00 plus 11% sales taxes.
Lyn buys a hat for $21.00 plus 9% sales taxes.
a) How much do Tom and Lyn pay for the hats? Show your work.
b) Who spent more on taxes?
Answers
Answer:
a)
Tom
Tax = (11/100) × 13
Tax = $1.43
Tom paid 13 +1.43 = $14.43
Lyn
Tax = (9/100)× 21
Tax = $1.89
Lyn paid 21 + 1.89 = $22.89
b) Lyn paid more for taxes.

Sam's Saddles is having a sale on cowboy hats. The hats are being sold for
a 30% discount. The expression below can be used to determine the cost
of a hat on sale (h). h -0.3h Which expression could also be used to determine the cost of a hat on sale?
0.30h
0.70h
1.30h
1.70h
Answers
Answer: 0.70h
Step-by-step explanation:
The hat is being sold at a 30% discount. The expression that shows this will be:
Price = h - 0.3h
When the 0.3h is subtracted from h, we have:
= 0.7h
Another way to get to that expression:
Hat is being sold at 30% discount which means that 30% has been removed from the value leaving:
= 100% - 30%
= 70%
Price is now 70% * Normal price which is denoted as h.
= 70% * h = 0.7h

Which equation best represents c, the total amount Mr. Thomas should be charged
for driving m miles?
Answers
Answer:
c = 0.15m + 45
Step-by-step explanation:
Generally, we have the equation of a straight line as;
y = mx + b
where m is the slope and b is the y-intercept
To get the value of m, we can use the slope equation
m = (y2-y1)/(x2-x1)
Let us select two points to use from the table
we have;
(40,51) and (20,48)
So substituting these values;
m = (48-51)/(20-40) = 0.15
So we have the partially completed equation as;
y = 0.15x + b
To get the value of b, we use any of the points
Using the last, we have
51 = 0.15(40) + b
b = 45
So we have the complete equation as;
y = 0.15x + 45
using the terms in the question, we have;
c = 0.15m + 45

Bananas cost 0.59 per pound. Create an equation that could be used to find the total cost of y of x bananas
Answers
Answer:
y = 0.59x
Step-by-step explanation:
Cost per pound of banana = $0.59
If Number of banana's = x
Total Cost of an item = price per item * number of items
Therefore,
Total cost, y = price per pound of banana * number of bananas
y = 0.59 * x
y = 0.59x

Rolando imported 138 boxes of mangoes.
There were 24 mangoes in each box.
He reserved 72 mangoes for his friends and sold the rest to 3
customers.
If each customer bought an equal number of mangoes, how
many mangoes did each customer buy?
Answers
Answer:
Each customer bought 45 boxes which is equivalent to mangoes 3240 in total.
Step-by-step explanation:
1. Subtract 3 boxes from the total of 138 imported boxes. ( 3 boxes are the 72 mangoes for his friends )
2. Divide 135 by 3 ( The amount of customers ) = 45 boxes per customer.
3. 45 x 24 ( The amount of mangoes in each box ) = 1080
4. 45 boxes/1080 mangoes per customer.
To recheck:
1080 x 3 ( The amount of customers again ) = 3240.
135 x 24 ( The amount of mangoes per box ) = 3240.
I Hope this helped! :)

A cyclist rides his bike at a speed of 27 miles per hour what is the speed in miles per minute? How many miles will the cyclist travel in 2 minutes ? Do not round answer
Answers
Answer:
The cyclist can travel 0.9 miles in 2 minutes.
Step-by-step explanation:
1 hour = 60 minutes
Set up a conversion equation:
27 mi/1 hr × 1hr/60 mins
It is easier to see when writing it on paper, but the fractions are set up in a way to cancel the units out until the only units left are miles and minutes
After multiplying the numerators together and then multiplying the denominators together, you should reach the answer:
27 mi/60 mins
The cyclist can travel 27 miles in 60 minutes, but how many miles can he travel in 2 minutes?
Set up an equation:
Variable x = number of miles
27 mi/60 mins = x/2 mins
Cross multiply
27 × 2 = 60 × x
54 = 60x
Divide both sides by 60
0.9 = x

x = 50
Can I have Brainliest?
The triangle in the picture is an isosceles triangle, that means two of the sides are equal. An isosceles triangle has two equal sides, therefore it also has two equal angles. That means that side QR is equal to QP, which also means that point P and point R have equal angles. We know that the angles in a triangle must always add up to 180°. We already know the information for angle R and angle P so we can add those together, this gets us 70°. We can now build an equation with the information we have: 2x + 10 + 70 = 180. Solve the equation and you’ll have your final product, x = 50.
Daniel deposits $8,000 into a continuously compounding interest account. After 18 years there is $13,006.40 in the account. What was the interest rate?
Answers
Answer:
r = 2.7%
Step-by-step explanation:
Interest rate compounded continuously
r = ln(A/P) / t
Where,
r = interest rate
A = future value
P = principal
t = time
r = ln(A/P) / t
r = ln(13,006.40/8,000) / 18
= ln(1.6258) / 18
= 0.4860000023303 / 18
= 0.0270000001294
Approximately
r = 0.027
Convert value of r to percentage
r = 0.27 × 100
r = 2.7%
