a.
(3x + 2y = 6
(13x + 2y = 3
b.
(6x+2y = 8
(3x - y = -2
Answer:
A. x = -3/10 , y = 69/20
B. x = 1/2 , y = 5/2
Step-by-step explanation:
A]
3x + 2y = 6......eq1
13x + 2y = 3.......eq2
From eq 2 - eq 1
10x = -3
x = -3/10
So,
3x + 2y = 6
3(-3/10) + 2y = 6
y = 69/20
B]
6x+2y = 8.....eq1
3x - y = -2.....eq2
eq2 x 2 and add in 1
12x = 6
x = 1/2
So,
6x+2y = 8
y = 5/2
Sally bought a sweater for $24.99 with a 25% discount. What is the price of the
sweater after the discount?
There are two ways to do this, the one that makes more logical sense and the faster one
You can first calculate how much is 25%. You do this by $24.99 × 25 ÷ 100
Since you know how much is "discounted", just minus the answer you get above with the original price ($24.99 - $6.2475)
The quicker way is to recognise that "original price" is always 100%. In other words, you can just do 100% - 25% and get 75%. Then, $24.99×75÷100 is your answer.

Answer:
b = 8.89, c = 11.96 and m∠B = 48°
Step-by-step explanation:
From the given triangle ABC,
We will apply sine ratio for angle A,
sin(A) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
sin(42)° = [tex]\frac{BC}{AB}[/tex]
sin(42)° = [tex]\frac{8}{AB}[/tex]
AB = [tex]\frac{8}{\text{sin}(42)}[/tex]
AB = 11.96
c = 11.96
By triangle sum theorem,
m∠A + m∠B + m∠C = 180°
42° + m∠B + 90° = 180°
m∠B = 180 - 132
m∠B = 48°
By cosine ratio of angle A,
cos(A) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
cos(42)° = [tex]\frac{AC}{AB}[/tex]
AC = AB.cos(42)°
AC = (11.96)cos(42)°
AC = 8.89
b = 8.89

Answer/Step-by-step explanation:
Decompose each shape, find the volume of each cuboid, and add both volumes you get together.
Recall: volume of cuboid = L*W*H
4. Volume of cuboid 1: L*W*H = 12*10*4 = 480 ft³
Volume of cuboid 2: L*W*H = 12*3*5 = 180 ft³
Volume of the shape = 480 + 180 = 660 in.³
5. Volume of cuboid 1: L*W*H = 11*2*5 = 110 yd³
Volume of cuboid 2: L*W*H = 10*4*2 = 80 yd³
Volume of the shape = 110 + 80 = 190 yd³
6. Volume of cuboid 1: L*W*H = 8*3*2 = 48 in.³
Volume of cuboid 2: L*W*H = 14*2*3 = 84 in.³
Volume of the shape = 48 + 84 = 132 in.³
7. Volume of cuboid 1: L*W*H = 5*3*2 = 30 yd³
Volume of cuboid 2: L*W*H = 6*2*5 = 60 yd³
Volume of the shape = 30 + 60 = 90 yd³
8. Volume of cuboid 1: L*W*H = 12*2*18 = 432 in.³
Volume of cuboid 2: L*W*H = 18*5*6 = 540 in.³
Volume of the shape = 432 + 540 = 972 in.³
9. Volume of cuboid 1: L*W*H = 13*11*4 = 572 ft³
Volume of cuboid 2: L*W*H = 13*6*7 = 546 ft³
Volume of the shape = 572 + 546 = 1,118 ft³

Consider the triangle ABC:
AB is the same length as BC (marked), meaning ABC is an isosceles triangle.
Since ABC is isosceles, ∠BAC=∠BCA=53
All angles in a triangle add up to 180:
180=∠ABC + ∠BAC + ∠BCA
180= ∠ABC + 53 +53
∠ABC = 180 - 106
∠ABC = 74
Assuming BD bisects ∠ABC perfectly, x is half of ∠ABC.
x=74/2=37
If BD bisects AC perfectly, AD=DC=y=6

eva is working two summer jobs, making $16 per hour tutoring and $8 per hour clearing tables. Last week eva worked 3 times as many hours clearing tables as she worked hours tutoring hours and earned a total of $80. Graphically solve a system of equations in order to determine
Answer
y = 3(2) = 6
Thus, she tutored for 2 hours and cleaned tables for 6 hours.
Explanation
These questions are all about writing down mathematically what they are saying in words. Use variables whenever there is an unknown, and try to write equalities based on what is said.
So, taking it one step at a time:
Eva is working two summer jobs,
Cool.
making $16 per hour and $8 per hour clearing tables.
I'm guessing this is $16/hr for tutoring, and $8/hr for clearing tables?
Last week Eva worked 3 times as many hours clearing tables as she worked tutoring hours
Let C = the number of hours Eva worked at clearing tables
Let T = the number of hours Eva worked at tutoring
Last week Eva worked C = 3 * T
and earned a total of $80.
The amount she earned at each place is:
8*C = money from clearing tables
16*T = money from tutoring
8*C + 16*T = 80
Solve a system of equations in order to determine the number of hours Eva worked tutoring last week, X, and the number of hours Eva worked clearing tables last week, Y,
Welp, I guess they wanted X and Y but it doesn't matter. From the equations above we can say:
8*C + 16*T = 80
C = 3*T
That should be enough to solve for:
C = ?
T = ?
Let x = # of hrs spent tutoring, y = # of hrs spent cleaning tables
We know she worked 3 times as many hours cleaning tables as she did tutoring, which implies:
3x = y
Also, her total earnings add up to $80, which implies:
16x + 8y = 80
This gives us the following system of equations:
3x = y
16x + 8y = 80
Let's make the substitution y = 3x into the 2nd equation:
16x + 8(3x) = 80
16x + 24x = 80
40x = 80
x = 2.
Next, plug in x = 2 into the first equation:
y = 3(2) = 6
Thus, she tutored for 2 hours and cleaned tables for 6 hours.
A company that sold fish for an aquarium had a special one weekend on tetras and angel fish. The store sold a total of 110 of those types of fish over the weekend. The tetras each sold for $0.40 and the angel fish each sold for $1.20. If they made a total of $80 in selling those fish, how many tetras did they sell?
Answer: They sold 65 tetras.
Step-by-step explanation:
Let x= Number of tetras
y= Number of angel fish.
As per given,
x+y= 110 (i)
0.40x+1.20y=80 (ii)
Multiply 2.5 on both sides of (ii), we get
x+3y=200 (iii)
Eliminate (i) from (iii)
[tex]2y=90\\\\\Rightarrow y=45[/tex]
Put value of y in (i)
[tex]x+45=110\Rightarrow x=65[/tex]
Hence, they sold 65 tetras.
