Answer:
x = 45
Step-by-step explanation:
Re-order terms so constants are on the left
15 * x/9 - 42 =28
Combine multiplied terms into a single fraction
15x/9 - 42 = 28
Cancel terms that are in both the numerator and denominator

Solution:
Solve the system of equations to find the value of y.
10x + 10y = 405x + 3y = 8
10x + 10y = 402(5x + 3y = 8)
10x + 10y = 4010x + 6y = 16
4y = 24y = 6Substitute the value of y into any equation to find the value of x.
10x + 10y = 40=> 10x + 10(6) = 40=> 10x + 60 = 40=> 10x = -20=> x = -2Putting them in (x,y) form.

(4, 4) and (5, 3)
(12, –4) and (7, 1)
Answers
Answer:
(3, 5) and (-4, 12)
Step-by-step explanation:
To solve this system of equations, we'll use the substitution method.
Plug in the given y = x² - 4 into the other equation
x + x² - 4 = 8
Subtract 8 from both sides
x² + x - 4 = 8
- 8 - 8
x² + x - 12 = 0
Factor out the equation
x² + x - 12 = (x + 4)(x - 3) = 0
For the equation to be 0, x will have to equal -4 and 3
Now plug in the new x's into one of the original equations
We'll use y = x² - 4
y = (-4)² - 4 = 16 - 4 = 12
y = 3² - 4 = 9 - 4 = 5
When x = -4, y = 12, so one of the answers is (-4, 12)
When x = 3, y - 5, so one of the answers is (3, 5)

Answers
The paid amount including service fee, tip, and tax is $77.987.
what is the percentage?the percentage is value per hundred.
bill value = $59.99
service fee = 3% of $59.99 = 59.99*3/100 = $1.7997
tip = 20% of 59.99 = $11.998
tax = 7 % of $59.99 = $4.1993
total payment = 59.99+1.7997+11.998+4.1993 = $77.987
therefore, the paid amount including service fee, tip, and tax is $77.987.

Two angles of a triangle measure 75° and 40°. What is the degree measure of the third angle?
Answers
Answer:
the angles of a triangle always equal 180 so
75+40+x=180
115+x=180
-115
x=65
the other angle is 65
Hope This Helps!!!
65°
Step-by-step explanation:
let the third angle be x
so, sum of all angles of a triangle = 180°
x° + 75° + 40° = 180°
x + 115° = 180°
x = 180° - 115°

Step-by-step explanation:
Use the Law of Cosines to find the measure of segment c:
[tex]c=\sqrt{a^2+b^2-2ab*cos(C)}\\\\c=\sqrt{12^2+13^2-2(12)(13)*cos(134)}\\\\c=\sqrt{313-312cos(134)}\\\\c=\sqrt{313-312(-.6946583705)}\\\\c=\sqrt{313-(-216.7334116)}\\\\c=\sqrt{313+216.7334116}\\\\c=\sqrt{529.7334116}\\[/tex]
c ≈ 23.01593821 km ≈ 23 km
Since c = 23 km, our only options are choices B and D. Now, let's find the measure of angle A to confirm. To do this we will use the Law of Sines:
[tex]\frac{sin(A)}{a} =\frac{sin(C)}{c} \\\\\frac{sin(A)}{12}=\frac{sin(134)}{23.01593821}\\\\sin(A)=12(\frac{sin(134)}{23.01593821})\\\\A=sin^{-1}[12(\frac{sin(134)}{23.01593821})]\\\\[/tex]
A ≈ 22.02726885° ≈ 22°
Since the measure of c = 23 km and the measure of angle A = 22°, the answer must be choice B.
Kylie works at a local music store. The store receives a shipment of new CDs in a box. In the shipment, there are 10 country CDs, 5 rock CDs, 12 hip hop CDs, and 3 jazz CDs.
What is the probability that the first CD that Kylie pulls from the box will NOT be hip hop?
Answers
Answer:
Total number of CDs= 10+5+12+3=30
Number of jazz CD= 3
Total number of outcomes that Kyle will select a jazz CD from the box= 3C1= 3!/1!2!= 3
Total number of outcomes for any CD = 30C1 = 30!/1$29! =30
Hence, the probability of picking jazz CD =3/30 = 1/10 0.1
Now since, one CD is out, the total number of CD left = 29
No. of country CD= 10
Total number of outcomes that Kyle will select a country CD from the box= 10C1= 10!/1!9!= 10
Total number of outcomes for any CD(one is out) = 29C1 = 29!/1$28! =29
Hence, the probability of picking country CD =10/29 = 0.344827

Hexagon
Answers
A regular polygon with exterior angle of 7.2 degrees is a 50-gon.
Regular polygonRegular polygon are polygon that are equiangular. This simply means they are polygon with equal angles.
The formula to find the number of sides of a polygon using exterior angle is as follows:
exterior angle = 360 / nwhere
n = number of sides
Therefore,
7.2 = 360 / n
cross multiply
7.2n = 360
divide both sides by 7.2
n = 360 / 7.2
n = 50
The polygon has 50 sides. Therefore, it is a 50-gon

Find a formula for the n th term, T n , of the following arithmetic sequence: − 10 , − 22 , − 34 , − 46 ,. . . Hence, or otherwise, find the value of the 40th term, T 40
Answers
Answer:
T(40) = -478
Step-by-step explanation:
The first term is -10, that means a = -10
The difference between to first and second term is -12.
Therefore, d = -12.
We may set up the A.S. equation now:
T(n) = a + (n-1)d = -10 + (n-1)(-12)
Now plug in n = 40:
T(40) = -10 + (40-1)(-12) = -478

Pls help
Answers
If she spends $42 a week on coffee and every day she spends the same amount (I don't see this in the question, only doughnuts.), then $30 can get her 30 : 42 = 5/7 of a week of coffee -> 5 days.
So, she spends 5 days on coffee -> she must also spend 5 days on doughnuts
And since she spends 30 dollars equally everyday, she spends 30 : 5 = $6 everyday on doughnuts

What is algebraic expression?
Algebraic expression are the expression which consist the variables, coefficients of variables and constants.
The algebraic expression are used represent the general problem in the mathematical way to solve them.
The expression used by the Gabriel to represent his total cost is,
[tex]2.5x+2y - 2[/tex]
As, Gabriel has to receive the change amount of $30. Thus, he has to subtract this amount from the total cost. This statement can be present as,
[tex]\rm Change=30-(2.5x+2y - 2)\\\rm Change=30-2.5x-2y + 2\\\rm Change=32-2.5x-2y[/tex]
Now, the expression used by him to represent the amount of change he should receive from $30 is,
[tex]28 -2.5x - 2y[/tex]

Answers
Answer:
a = 16
b = 10
c = 19
d = 3
Step-by-step explanation:
For a, we know that 60 is 12+a+a+a, and to find what a is, we subtract 12 from 60, so that 48=3a, so 48 is a times 3. dividing 48 by 3 gives a=16
For b, we know that 60 is 4(b+5), dividing both sides by 4, 15=b+5. Subtracting 5 from both sides, b=10
For c, we know that a+b+c=3(b+5), or 16+10+c=45, subtracting 26 from each side, c=19
For d, we know that 3c+d=60, or (19*3)+d=60. simplifying, 57+d=60. subtraction 57 from each side gives d=3

Determine between which two whole numbers lies square root of 20
Answers
The square root of 20 is between 4 and 5.
Whole NumbersThey are the numbers represented by positive real numbers where the fractions and decimal numbers are not included.
For solving this question, you should list the whole numbers whose your square is less than 30. Your list must present the following numbers:
0 ⇒ 0²=0
1 ⇒ 1²=1
2 ⇒ 2²=4
3 ⇒3²=9
4 ⇒ 4²=16
5 ⇒ 5²=25
Note that 6²=36, it is greater than 30,because of this it is not in the previous list.
The question asks to determine between which two whole numbers lies the square root of 20. Therefore, from the previous list, it is possible to see that the value 20 is between 16 and 25. The square root of 16 and 25 is equal to 4 and 5, respectively.
Thus, the square root of 20 is between 4 and 5. You can check this results in your calculator:[tex]\sqrt{20}=2\sqrt{5}=4.47[/tex]
