A welcome kit contains 3 grocery store and seven drugstore coupons. The coupons are worth $45. Another welcome kit contains three grocery store coupons and six drugstore coupons worth $42. What is the value of each grocery coupon and each drug store coupon?
Answer:
The value of each grocery store coupon is $6
Then the value of each drugstore coupon is $3.
Step-by-step explanation:
Let's define:
G = value of a grocery store coupon.
D = value of a drugstore coupon.
We know that:
"A welcome kit contains 3 grocery store and seven drugstore coupons. The coupons are worth $45"
We can write this as:
3*G + 7*D = $45
And we also know that:
"Another welcome kit contains three grocery store coupons and six drugstore coupons worth $42"
We can write this as:
3*G + 6*D = $42
Then we have the system of equations:
3*G + 7*D = $45
3*G + 6*D = $42
To solve this, we can isolate the term "3*G" in one of the equations (because it appears on both of them)
Let's isolate it on the second equation:
3*G = $42 - 6*D
Now let's replace this on the first equation:
($42 - 6*D) + 7*D = $45
$42 + D = $45
D = $45 - $42 = $3
Then the value of each drugstore coupon is $3.
And we also have the relation:
3*G = $42 - 6*D
We can just replace the value of D to get:
3*G = $42 - 6*$3 = $42 - $24 = $18
G = $18/3 = $6
The value of each grocery store coupon is $6

Step-by-step explanation:
but the answer is the temperature dropped 15.6 degrees from the high that day which was 8 degrees
so the sum is: 8-15.6= -7.6
And that means the low temperature on Tuesday night was - 7.6 degrees

Answer:
m∠U = 36°
m∠V = 75°
m∠T = 69°
Step-by-step explanation:
(2x+14)+(6x+9)+(6x+3)=180
Combine like terms: 14x+26=180
Solve this equation: x=11
Use x=11 to find angles
∠U = 36°
∠V = 75°
∠T = 69°
You can add up all of these measurements to check. =180°
Answer:
The measures of the 3 angles are:Angle T = 69°Angle U = 36°Angle V = 75°Step-by-step explanation:
The Triangle Sum Theorem states that the 3 angles of a triangle must add up to 180°.
We don't know the angles of the triangle, but we do know that the sum of all three unknown angles is 180°.
We set the three expressions together as equal to 180°.
6x + 3 + 6x + 9 + 2x + 14 = 180
Simplify
14x + 26 = 180
Subtract 26
14x = 154
x = 11
Now, we check our answer for x.
6(11) + 3 + 6(11) + 9 + 2(11) + 14 = 180
69 (measure of angle T) + 75 (measure of angle V) + 36 (measure of angle U) = 180
180 = 180 ✅
Note that once we found x, would substitute it in and get the needed measures. Since the needed measures add up to 180°, we know that our answer is correct.
The measures of the 3 angles are:Angle T = 69°Angle U = 36°Angle V = 75°Solve for x: 5x-4(х+3)=8

x=20

Cynthia Besch wants to buy a rug for a room that is 24 ft wide and 32 ft long. She wants to leave a uniform strip of floor around the rug. She can afford to buy 560 square feet of carpeting. What dimensions should the rug have?
Answer:
[tex]D=(20.42)(28.42)[/tex]
Step-by-step explanation:
From the question we are told that
Width [tex]W=24ft[/tex]
Length [tex]L=32ft[/tex]
She can afford to buy 560 square feet of carpeting
Let
[tex]S=width\ of\ strip[/tex]
Generally the Dimension of the rug is mathematically given as
Width of Rug [tex]W' = (24- 2S)ft[/tex]
Length of Rug [tex]L'= (32-2S) ft[/tex]
Generally the width of strip S is mathematically given by
[tex](32-2s)*(24-2s)=560[/tex]
[tex]-4s-112s+208=0[/tex]
[tex]s_1=-29.7\\s_2=1.748[/tex]
Therefore the width is
[tex]s=1.748[/tex]
Generally the dimension of the rug D is mathematically given as
Width of Rug [tex]W' = (24- 2s)ft[/tex]
[tex]W' = (24- 2(1.79))ft[/tex]
[tex]W' =20.42ft[/tex]
Length of Rug [tex]L'= (32-2S) ft[/tex]
[tex]L'= (32-2(1.79)) ft[/tex]
[tex]L'=28.42 ft[/tex]
Therefore dimension of Rug is given by
[tex]D=(20.42)(28.42)[/tex]

How do I find these equations using substitution y=-3x+5 and 5x-4y=-3 ?
Answer:
x=1
Step-by-step explanation:
you would change it to 5x-4(-3x+5)=-3, because you put the info for the first equation into the second equation.
5x-4(-3x+5)=-3
5x+12x-20=-3
17x-20=-3
17x=17
x=1
Answer:
(1,2)
Step-by-step explanation:
1) To solve using substitution, first isolate one of the variables in one of the equations. However, the y in y = -3x + 5 has already been isolated, so we don't need this step. Instead, take that value of y and substitute it for the y in the other equation, 5x - 4y = -3. So, substitute -3x + 5 for the y in 5x - 4y = -3 and solve:
[tex]5x-4(-3x+5)= -3\\5x+12x-20=-3\\17x-20=-3\\17x = 17\\x = 1[/tex]
2) So, x = 1. Now, take that value of x and substitute back into any of the equations to find the y value. (I chose to substitute it into y = -3x + 5, but either choice is fine). So, substitute 1 for the x in y = -3x + 5 and solve:
[tex]y = -3(1)+5\\y = -3+5\\y = 2[/tex]
So, y = 2. Thus, by knowing both x and y values, the solution would be (1,2).

In Las Vegas, Nevada, stores charge a 4.6% state sales tax and a 3.65% county sales tax. Yuki is purchasing a handbag priced at $220 before tax.
How much sales tax does Yuki pay for her handbag purchase?
Answer:
$18.15
Step-by-step explanation:
Yuki is paying tax of 4.6% + 3.65% = 8.25%
Converting to decimal form, that is 8.25/100 = 0.0825
Multiply that by the original sale price. 0.0825 x $220 = $18.15 exactly for tax.
The question asks for the tax, NOT for the total she will pay. Please don't get them mixed up.

If cos 0 = 3/5
and angle 0 is in Quadrant IV, what is the value of tan 0 ?
Tan =
Answer:
-4/3.
Step-by-step explanation:
cos O = 3/5
Using Pythagoras to find the length of the side opposite the angle O:
As the cos of O is adjacent/ hypotenuse, Hypotenuse = 5 , adjacent side = 3 so
opposite side. = sqrt(5^2 - 3^2) = sqrt 16
= 4.
Now the tangent is negative in Q IV so
tan O = opposite / adjacent side = -4/3

For The triangles have the same angles which checks out and the side sides, if say you simplified the sides or whatever
Therefore, its C
Hope I Helps!
Answer:
C. Triangles A and CStep-by-step explanation:
Given triangles A, B and C
Triangles A and C have congruent angles of 23° and 67° and similar sides with the scale factor of 3.
Triangle B is different, with angles 28° and 62°, therefore can't be similar to A or C.
Correct choice is C

You are offered two different sales jobs. The first company offers a straight commission of 8% of the sales. The second company offers a salary of $ 500 per week plus 3% of the sales. How much would you have to sell in a week in order for the straight commission offer to be at least as good
Answer:
You would have to sell 10,000 in a week for the straight commission offer to be at least as good.
Step-by-step explanation:
From the information provided, you can find how much you would have to sell in a week in order for the straight commission offer to be at least as good by establishing an equation in which the amount earned in the first company is equal to the amount earned in the second company:
0.08x=500+0.03x, where x is the amount of sales
Now, you can solve for x:
0.08x-0.03x=500
0.05x=500
x=500/0.05
x=10,000
According to this, the answer is that you would have to sell 10,000 in a week for the straight commission offer to be at least as good.
