Answer:
one shirt 25.00 one sweater 16.00
Step-by-step explanation:
$\text{one shirt: }\$25,\text{ one sweater: }\$16$
Let x be the cost of one shirt and y be the cost of one sweater; then
5x+5y6x+9y=205=294
The augmented matrix for this system of equations is
[5659205294]
Using Gaussian elimination, divide row one by 5 to get
[161941294]
Multiply row one by −6 and add the result to row two to get
[10134148]
Divide row two by 3 to get
[10114116]
After back substitution, y=16 and x=25.
The cost of one shirt is $25 and cost of sweater is $16.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Let x be the cost of one shirt and y be the cost of sweater.
5 shirts and 5 sweaters cost $205
5x+5y=205...(1)
6 shirts and 9 sweaters cost $294
6x+9y=294...(2)
Multiply equation (1) with 6 and equation (2) with 5.
30x+30y=1230..(3)
30x+45y=1470...(4)
Subtract 3 and 4
30y-45y=1230-1470
-15y = -240
Divide both sides by 15
y=240/15
y=16
Now plug in y value in any of the equation
5x+16(5)=205
5x + 80 = 205
5x = 125
Divide both sides by 5
x=25
Hence, the cost of one shirt is $25 and cost of sweater is $16.

Find the measure of A as indicates in the picture.
In case the picture blurs
Top angle = x + 63
Left angle = x + 96
Right angle = x + 149
Answer:
∠A = 58°
Step-by-step explanation:
all triangles contain 180°
180° - 149° = 31°
x + 63° + x + 96° + 31° = 180°
combine like terms:
2x + 190° = 180°
2x = -10°
x = -5°
∠A = -5° + 63° = 58°

Please Hurry) Consider the quadratic equation 3x^2 - 6 = 2x. A) What is the value of the discrimination? B) What does the discrimination of the quadratic equation tell about the solutions to 3x^2 - 6 = 2x?. ( Will Mark Brainliest). Show your work.
Answer:
A. 76
B. We will get two real solutions for the equation.
Step-by-step explanation:
A
For any quadratic equation ax²+bx+c=0, the discriminant is b²-4ac.
In 3x²-2x-6=0, a=3, b=-2 and c=-6:
b²-4ac
(-2)²-4(3)(-6)=4+72=76
B.
When the discriminate is positive we get two real solutions to the equation, when it's zero we get one real solution, and when it's negative we get two complex solutions. Since our discriminate, 76, is positive, we know that we will get two real solutions to 3x²-6=2x.

Answer:
C. 22/7
Step-by-step explanation:
You may be aware that 22/7 is a value used to approximate π almost as often as is 3.14.
__
In case you actually want to carry out the calculations, you have ...
C = πd
π = C/d
π ≈ (60 3/50)/(19 11/100) = (3003/50)/(1911/100) = 6006/1911 = 22/7
π ≈ 77/(24 1/2) = 77/(49/2) = 22/7
π ≈ (86 9/10)/(27 13/20) = (869/10)/(553/20) = 1738/553 = 22/7
π ≈ 99/(31 1/2) = 99/(63/2) = 22/7
is this a function ? please help !
Answer:
Well it is a function because the way I’m looking at it is that the lines never overlap each other except for the X and y axis but those arent lines. The line is just straight and nothing else overlaps or courses it. So it Is a function.

Find the circumferences of both circles to the nearest tenth.
Two circles lying one inside the other. The inner circle is shaded orange and the outer circle is shaded blue. The radius of the inner circle is labeled 5 centimeters. The distance between the outer and the inner circle is circle is labeled 5 centimeters.
The circumference of the blue circle is about
cm.
The circumference of the orange circle is about
cm
Answer:
The circumference of the blue circle is about
62.8 cm.
The circumference of the orange circle is about
31.4 cm.
Step-by-step explanation:
First the blue circle, it shows that there are 5 cm on the outside of the orange circle so the would be 5+5=10, then you add the orange circle to the 10 cm, that would give you 20 cm. Then you multiply 20 cm by pi (3.14) which will give you your answer 62.8. Do the same thing for the orange circle, 5+5=10 so 10 multiplied by pi (3.14) is 31.4
