Answer:
A∩B = 2,4
A-B = 1,3,5
sin (A+B) = sin(A)cos(B)+cos(A)sin(B)
Step-by-step explanation:
A intersects U means the numbers that are coming to both A and U
set a minus set b of the numbers that are not common to B
multiply the numerator and the denominator by csc(x)
NOTE: I substituted x for theta as I don't have theta on my phone
[tex] \frac{ \csc(x) }{ \csc(x)} \frac{ \tan(x) - \sin(x) }{ \tan(x) + \sin(x) } = \frac{ \sec(x) - 1}{ \sec(x) + 1} [/tex]
[tex] \frac {\csc(x)}{\csc(x)} \frac {\frac ({\sin(x)}{\cos(x)}-\sin(x)} {\frac ({\sin(x)}{\cos(x)} + \sin(x)}) [/tex]

Answer: Five times a number is equal to the addition of three more than that number times the number itself and (-8) times 3 more than that number.
If x = 4 and y = 7, evaluate the - following expression: 20 +2(3y - 4x)
Answer:
110
Step-by-step explanation:
Substitute x = 4 and y = 7
20 + 2 (3y - 4x)
= 20 + 2 [(3 x 7) - (4 x 4)]
= 20 + 2 (21 - 16)
= 20 + 2 (5)
= 22 (5)
= 110
Answer:
30 (always use .P.E.M.D.A.S.)
Step-by-step explanation:
20+2(3y-4x)
20+2(21-16)
20+2(5)
20+10

Which offer results in the cheapest cake: 8 cakes for £3.20 or 5 cakes for £1.90. Explain your answer
Answer:
5 cakes for 1.90 (i dont have pounds symbol)
Step-by-step explanation:
To find the cheapest cake, divide both numbers (3.20, 1.90) by the number of cakes (8, 5)
3.20 ÷ 8 = 0.4 per cake
1.90 ÷ 5 = 0.38 per cake

The seventeen students on the Math Team want to raise $500 to buy practice books. They have already raised $234.63. If each student raises the same amount, how much more money must each student raise?
Answer:
Roughly $29.50 dollars.
Step-by-step explanation:
To find the answer you would
500 ÷ number of students
to find how much every student should raise.
500 ÷ 17 = 29.41
If we round out to make it simpler, each student must raise $29.50.

Answer:
70°
Step-by-step explanation:
An euclidean triangle (a triangle on a straight plane) has sum of three angles equal to 180°.
When we talk about a triangle, we usually talk about an euclidean one.
There are also a non-euclidean triangles which are a triangle on circular plane which has sum of angles above 180° and one that is a hyperbolic triangle version which has sum below 180°.
Back to the question, since we know that the triangle is an euclidean one and thus has the sum equal 180°.
x+20+40+2x-30 = 180
Combine like terms:
3x+30=180
Subtract both sides:
3x+30-30=180-30
3x=150
Divide both sides by 3.
3x/3 = 150/3
x = 50
Since we want to find angle B which has measure of 2x-30, substitute x = 50 in 2x-30.
2(50)-30 = 100-30 = 70
Therefore angle B is 70°

Ann made $143 for 11 hours of work.
At the same rate, how many hours of work would she have to work to make $243
Answer:
22 hours
Step-by-step explanation:
So, 143 equals eleven hours. 143 plus 143 would equal 243. So, you have two 143s which means you should multiply the 11 hours by two. 11x2 equals 22.

Line a and line c are perpendicular and m<26 = (5x+7). Find the value of x.
Answer in fraction form = 83/5
Answer in decimal form = 16.6
==================================================
Explanation:
All eight angles shown are 90 degrees since lines a and c are perpendicular to each other. Perpendicular lines form right angles.
Set 5x+7 equal to 90 and solve for x
5x+7 = 90
5x = 90-7
5x = 83
x = 83/5 is the fraction form of the answer
x = 16.6 is the decimal form of the answer
Answer:
83/5 = 16.6
Step-by-step explanation:
5x+7 = 90
5x = 90-7 subtract 7 from both sides.
5x = 83
x = 83/5 = 16.6
5. Domingo earns $13 dollars per hour and worked 47.5 hours that week. He is paid
double time for all hours worked over 40 hours in one week. What is his gross pay
for the week?
Answer:
$715
Step-by-step explanation:
$13 x 40 hours = $520
47.5 hours - 40 hours = 7.5 overtime hours
2 x $13 = $26 per overtime hour
$26 x 7.5 = $195
$520 + $195 = $715

Answer:
To solve the equation: First, subtract 9 from both sides of the equation. Second, divide both sides of the equation by -10
Step-by-step explanation:
We are subtracting from both sides because we need to do the inverse, and the inverse of adding 9 is subtracting it.
Same with the -10. We need to do the inverse, and the inverse of multiplying by -10 is dividing by it.
Answer:
First: Subtract 9 from both sides of the equation. Second: Divide both sides of the equation by -10
Step-by-step explanation:
because 9 is positive, to get rid of it you need to subtract it.
after than, you would get -10x = -30
you would then divide it by -10 because you need to get x by itself
x = -3
