Blue Tide Swim Shop is having its annual summer sale, when every item in the store gets
marked down, During the sale, rashguards sell for $5 less than full price. Miguel purchases 3
rashguards and pays a total of $60.
Which equation can you use to find how much money, f, each rashguard costs at full price?

Answer:

y=4x+3

=)4x=y-3

=)x=(y-3)/4

Answer:

[tex]\frac{y - 3}{4}[/tex]

Step-by-step explanation:

To make x the subject, first, subtract 3 from both sides:

y = 4x + 3 → y - 3 = 4x

Next, divide both sides by 4 to get x on its own:

y - 3 = 4x → (y - 3)/4 = x

Hope this helps

Answer:

53 divided by 3 would be $17.66

so 17.66 times 9 would be $158.94

Answer:

158.4 dollars

Step-by-step explanation:

so first of all the three tickets were 53 dollars so we divide the dollars and the no of tickets like this 53÷3 = 17.6 dollars

so since each ticket is 17.6 dollars now we know that Rosie wants to purchase 9 tickets so we will multiply the no of tickets by dollars per ticket like this

9×17.6= 158.4 dollars

and 158.4 is your answer

Answer:

[tex] \sin(2x) = 2 \sin(x) \cos(x) \\ 9( 2 \sin(x) \cos(x) ) \sin(x) = 9 \cos(x) \\ 18 { \sin}^{2} (x)9 \cos(x) - 9 \cos(x) = 0 \\ 9 \cos(x) (2{ \sin}^{2} (x) - 1) = 0 \\ 9 \cos(x) = 0 \: or \: 2{ \sin}^{2} (x) - 1 = 0 \\ \sin(x) = \pm \frac{1}{ \sqrt{2} } \\ \cos(x) = 0 \\ x = { \cos}^{ - 1} (0) \\ x = \frac{ \pi}{2} = 90 \degree \\ x = \frac{ \pi}{2} + 2\pi \: n \: \forall \: n \: \in \: \Z \\ = 90 \degree + 360\degree\: n \: \forall \: n \: \in \: \Z \\ = \pm\frac{ \pi}{4} \pm2\pi \: n \: \forall \: n \: \in \: \Z \\ x = \pm45\degree \pm 360\degree\: n \: \forall \: n \: \in \: \Z[/tex]

Answer:

the third one

Step-by-step explanation:

The line passes through the point

Step-by-step explanation:

shape BCD is an isosceles triangle meaning the base angles will be the same.

CA is a straight line meaning that it is 180

the sum of angles in a triangle always is 180

so

180-36= 144

to find x you need to half 144 as it is the sum of the base angles of the isosceles triangle.

144/2= 72

x=72

the angle just below y is also 72.

as CA is a straight line,

180-72= 108 giving you the answer for y

y= 108

so to make the answer clear

x= 72

y= 108

hope that helped! :)

Answer:

(12 + x)/(15 + x) = 85/100

Step-by-step explanation:

12/15 = 0.8

She currently has an 80% rate.

To raise it, she needs to make x shots. Since she makes all x shots, we add x to both the number of shots made and attempts.

She will make 12 + x shots in 15 + x attempts.

We want that rate to be 0.85 which is the same as 85%.

(12 + x)/(15 + x) = 85/100

(12 + x)/(15 + x) = 17/20

20(12 + x) = 17(15 + x)

240 + 20x = 255 + 17x

3x = 15

x = 5

Answer:

The equation is (12 + x)/(15 + x) = 85/100.

Based on the data, it can be inferred that Harrisburg, PA is 158 miles from Trento, NJ.

To calculate the distance between Harrisburg and Trento we must carry out the following procedure. First we look at the entire table to see the different distance values between the cities. As we can see, the values for Trento, NJ are not there, so we will have to look elsewhere for additional information.

In this case, we must take as a reference the closest city to Trento that is on the list, this would be Filadeldia. Now, we must find the distance between Philadelphia and Trento and add this value to the distance between Philadelphia and Harrisburg.

According to the above, Philadelphia is 114 miles from Harrisburg and 44 miles from Trneto.

Based on the above, the total distance between Trento and Harrisburg is 158 miles.

Answer:

7.35

Step-by-step explanation:

4/7w=4.2

multiply both sides by 7

24/7w=29.4

simplify

4w=29.4

divide both sides by 4

w=7.35

Answer:

w equals 7.35

Step-by-step explanation:

7 times 4/7w = 4.2 times 7

4w = 29.4

Divide: 4w/4 = 29.4/4

w = 7.35

Answer:

C.

Step-by-step explanation:

Answer: C

Step-by-step explanation:

Say we had 2 fractions:

2/4 & 3/6

and we were trying to find out if they were proportional.

An easy way to do this is to divide the numerator of the second fraction by the numerator of the first fraction, then multiply what you get by the denominator of the first fraction. If your final number equals the denominator of the second fraction, then the two fractions are proportional.

Let me demonstrate:

2/4 and 3/6

1. 3 ÷ 2 = 1.5

2. 1.5 × 4 = 6

3. 6 = 6

Therefore, these fractions are proportional.

Let's try another problem:

4/5 and 10/19

1. 10 ÷ 4 = 2.5

2. 2.5 × 5 = 12.5

3. 12.5 ≠ 19

Therefore, these fractions are not proportional.

Hope this helps!

Step-by-step explanation:

You cannot simplify this fraction any more. The two fractions have the same denominator you can just add the numerators.

Answer:

The slope of Function A is less than the slope of Function B.

Step-by-step explanation:

Using the slope formula:

m = (y2 - y1)/(x2 - x1)

and the following ordered pairs from Function A:

(x1, y1) = (-5, -3)

(x2, y2) = (-10, -8)

m = (y2 - y1)/(x2 - x1)

[tex]m = \frac{-8 - (-3)}{-10 - (-5)} = \frac{-8 +3}{-10+5} = \frac{-5}{-5} = 1[/tex]

Since Function A's slope = 1, and Function B's slope = 4, then it means that the slope of Function A is lesser than the slope of Function B.
