Melanie saves $20 every month in her savings account. She withdrew $60 one time to go shopping. She now has $280 in her account. Which equation represents this situation?
20m/60 = 280
20m/60 = 280
20m + 60 = 280
20m + 60 = 280
20m - 60 = 280
20m - 60 = 280
20m (60) - 280
Answer:
20m - 60 = 280

If sin3A=-root 3 / 2 , find the values of A where 0 degrees is greater to or equal than A is greater to or equal than 360 degrees
Answer:
A is 20°
Step-by-step explanation:
Given sin3A = (√(3))/2. To find A we firstly take the sin^-1 of both sides and we have:
3A = sin^-1(√(3)/2)
We know that sin60° = √(3)/2. Therefore, sin^-1(√(3)/2) = 60°. Hence, we have
3A = 60°.
To get A, divide both sides by 3:
.A = 20°. Therefore, A is 20°.
Someone please help?? This is constant of proportionality... I don't get it at all and I need to turn this is ASAP!!!
Answer:
Step-by-step explanation:
From the given graph the line is straight ,so it means that the relation between x and y is directly proportional
(or) you can also say that at each point the slope of the line is same
slope =y/x , slope= 26/2 = 65/2 = 117/9 =13
hence slope is same that's why relation between x and y is direct relation
y∝ x
y=k*x
k=y/x
putt any point one the line to find the value of constant of proportionality,
i putt (2,26)
k=26/2 =13 value of proportionality constantnow to find cost of 14 tickets ,we have y=13*x , now putt x=14we will get cost(its on y-axis while ticket is on x-axis)y=13*14y= $182 cost of 14 ticketsso "C" option is correctAnswer:

Preston works at a grocery store and earns between $64 and $81 each day he works. Which is a reasonable estimation of how much Preston will earn if he works 5 days?
Answer:
[tex]P=\$362.5[/tex]
Step-by-step explanation:
From the question we are told that
Preston Earns \triangle x=$64-$81
Number of days D=5 days
Generally the average amount of money made by Preston is given by
[tex]X_a_v_g=\frac{64+81}{2}[/tex]
[tex]X_a_v_g=\$72.5[/tex]
Generally a reasonable estimation of how much Preston will earn if he works 5 days P is mathematically given by
[tex]P=72.5*5[/tex]
[tex]P=\$362.5[/tex]

Which three expressions in the table below have a solution of 10 when
x = -1 and y = 2
Answer:
The expressions are;
-5(x)(y)
8-y/x
Step-by-step explanation:
Here, we want to select expressions on the table having a solution of 10, given the value of x and y
For ;
-x(10) = -1(10) = -10
x + y + 7
-1 +2 + 7 = 8
8 -y/x = 8-(2/-1) = 8 + 2 = 10
-5(x)(y)
= -5(-1)(2) = 10
16-x + y - 7
16-(-1) + 2 - 7
16 + 1 + 2 - 7 = 12
For Exercises 8-10, use trapezoid DEFG with EG = 21 ft and m DGF = 77 to find each measure.

10. m<DEF=
Answer:
what class is this ???
Step-by-step explanation:
The value of each measure are,
8. ED = 16 ft
9. DF = 21 ft
10. m ∠DEF = 103°
What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
In trapezoid DEFG,
⇒ EG = 21 ft and m ∠DGF = 77°
Now, We know that;
In trapezoid, The sum of the angles on the same side is equal to 180°.
Hence, We get;
⇒ ∠ DGF = ∠ GDE = 77°
And, We get;
⇒ ∠ DEF + ∠ EDG = 180°
⇒ 77° + ∠ DEF = 180°
⇒ ∠ DEF = 180° - 77°
⇒ ∠ DEF = 103°
Since, In trapezoid opposite non parallel line are equal in length.
Hence, We get;
⇒ ED = FG
⇒ ED = 8 + 8
⇒ ED = 16
In trapezoid, Diagonal are equal in length.
Hence, We get;
⇒ DF = EG
⇒ DF = 21 ft

(PLS HELP ITS EASY) which of the following is a solution to the system of equations shown below?
1 x=10 and y=21. 2x+3y=83
2 x=7 and y=23. y=2x+9
3 x= -4 and y=1
4 x=4 and y=25
Answer:
A solution of the system of equation given in the question is;
(2) x = 7 and y = 23
Step-by-step explanation:
The given system of equation are;
2·x + 3·y = 83...(1)
y = 2·x + 9...(2)
Substituting the value of y = 2·x + 9 from equation (2) into equation (1) gives;
2·x + 3·y = 2·x + 3 × (2·x + 9) = 83
∴ 2·x + 6·x + 27 = 83
8·x = 83 - 27 = 56
x = 56/8 = 7
x = 7
By substituting the value of x = 7 derived above into equation (1), we have;
y = 2·x + 9
Where;
x = 7
y = 2 × 7 + 9 = 14 + 9 = 23
y = 23.

x + 4y = 7
4x – 3y = 9
Answer
{3,1}
Explaination
3 +4=7[1] x = -4y + 7
// Plug this in for variable x in equation [2]
[2] 4•(-4y+7) - 3y = 9
[2] - 19y = -19
// Solve equation [2] for the variable y
[2] 19y = 19
[2] y = 1
// By now we know this much :
x = -4y+7
y = 1
// Use the y value to solve for x
x = -4(1)+7 = 3
Solution :
{x,y} = {3,1}

If p(x) = 2x - 5 and r(x) = 3x + 4, calculate (pr)(x).
A 6x2 - 7x - 20
B 6x² +7X-20
C 5x - 1
D 6x2 - 20
Answer:
A) 6 x² - 7x - 20
Step-by-step explanation:
Explanation:-
Given p(x) = 2 x-5 and r (x) = 3 x +4
(pr)(x) = p(x) r(x)
= (2x -5)( 3 x +4)
= 2x(3x +4) -5( 3x +4)
= 6 x² + 8x - 15 x - 20
= 6 x² - 7x - 20
(pr)(x) = 6 x² - 7x - 20

The roof of a building is 9 m high. A rope is tied from the roof to a peg on the ground 12 m away from the wall. What is the length of the rope?
Answer:
15 m
Step-by-step explanation:
Height of buiding h= 9m
Lenght from building l= 12m
let the length of the rope be x=???
Applying Pythagoras theorem
x^2=h^2+l^2
x^2= 9^2+12^2
x^2= 81+144
x^2=225
square both sides
x=√225
x=15 m
Hence the length of the rope is 15 m
Someone please solve x for me
Answer:
x = 20
Step-by-step explanation:
added together, the angles make 180
3x + 80 + 2x = 180
subtract 80 from both sides of the equation
3x + 80 - 80 + 2x = 180 - 80
combine like terms
5x = 100
divide both sides by 5
5x/5 = 100/5
x = 20
Answer:
x = 20
Step-by-step explanation:
added together, the angles make 180
3x + 80 + 2x = 180
subtract 80 from both sides of the equation
3x + 80 - 80 + 2x = 180 - 80
combine like terms
5 x = 100
divide both sides by 5
5x/5 = 100/5
x = 20
