Solve and check -2x + 3 = -11
Answer:
x=7
Step-by-step explanation:
1. -2x+3=-11 << first make sure the x is one one side of the equal sign. so remove the 3, by subtracting if from 11
2. -2x+3=-11
-3 -3
=
3. -2x= -14 << then so isolate the x= divide -2 from -14 (two negatives divided equals a positive)
4. x=7

Answer:
Step-by-step explanation:
(3t + 4) + (4t + 3)
Part a
Remove parentheses
3t + 4 + 4t +3
Add
7t + 7
Part b
3t has the same variable ("t") as 4t. And 4 and 3 are both constants (or numbers). Thus, you can add the 3t and 4t together and add 3 and 4 together

Suppose you know that ∠S and ∠Y are complementary, and that m∠S = 2(m∠Y) − 60°. Find m∠Y.
The value of m∠Y is
I NEED HELP!!! PLS
Answer:
m∠Y=50°
Step-by-step explanation:
So, we know that ∠S+∠Y=90 and that m∠S=2(m∠Y)-60.
If you plug those things into the equation, you get (2[m∠Y]-60)+m∠Y=90.
Then you multiply 2 and m∠Y: 2m∠Y-60+m∠Y=90.
Combine like terms: 3m∠Y-60=90.
Then you add 60 to both sides: 3m∠Y=150
Divide 3 on both sides: 3∠Y=50

-x+y = 5
x - 5y = -9
Solve by elimination
Y and x
Answer:
x = -4 and y = 1
Step-by-step explanation:
-x + y = 5
+ x - 5y = -9 <— let’s eliminate x
————————————-
-4y = -4
y = 1
x - 5y = -9 <— substitute for y
x - 5(1) = -9
x - 5 = -9
+5 = +5
x = -4

Si debes tomar 0.035 litros de agua por cada kg de peso al día, si pesaras 50 kg ¿Cuánta agua deberás beber en un día? ayuda porfavor
Answer:
Deberás beber 1.75 litros de agua en un día.
Step-by-step explanation:
De acuerdo a la información dada, puedes utilizar una regla de tres para encontrar la cantidad de agua que deberás beber en un día si pesas 50 kg dado que debes tomar 0.035 litros por cada kg:
1kg → 0.035 litros
50 kg → x
x=(50*0.035)/1=1.75 litros
De acuerdo a esto, la respuesta es que deberás beber 1.75 litros de agua en un día.

Step-by-step explanation: I took the test on edge and got it right
The equation that is true for triangle QRS is -
Sin(100°)/3.5 = sin(S)/2.4
What is the law of sines?The law of sines can be stated as -
Sin(α)/a = Sin(β)/b = Sin(γ)/c
Given is to identify the equation that is true for triangle QRS.
Refer to the triangle as shown in the image attached. Using the law of sines, we can write -
Sin(α)/a = Sin(β)/b
Sin(100°)/3.5 = sin(S)/2.4
Therefore, the equation that is true for triangle QRS is -
Sin(100°)/3.5 = sin(S)/2.4

If an investment's value can be modeled with A= 325 (1+.027/12)^12t
then which of the following describes the investment?
Answer:
Step-by-step explanation:
It's an investment that has a nominal interest rate of 2.7% compounded monthly
3. The investment has a nominal rate of 27% compounded 12 times per year
Given that,
The investment value should be [tex]A= 325 (1+.027\div 12)^12t[/tex].Based on the above information, the information is as follows:
The above formula represent that the investment should have the nomibal rate of 27% that compounded 12 times per year.

Sheila has 28 stickers to divide evenly among 3 friends. She thinks there will be no leftovers. Use what you know about factor pairs to explain if Sheila is correct.
Answer:
She is wrong
Step-by-step explanation:
If our target number is 28 then we can create all of the following factor pairs for this number. These would be the following...
1, 2, 4, 7, 14 and 28
As we can see from the factor pairs there is no 3. This means that 3 would not divide evenly by 28 and cannot be multiplied by any whole number to create 28. Therefore, if you divide the 28 stickers by the 3 friends there will be some stickers leftover always.
The diagram shows a vector of a circle centre O and radius 6 cm. Mn is a chord of the circle. Angle MON is 50degrees. Calculate the area of the shaded segment. Give your answer to three significant figures
Answer:
Area of the shaded region = 1.92 cm²
Step-by-step explanation:
Area of the shaded region = Area of sector OMN - Area of isosceles triangle OMN
Drop a perpendicular OP from vertex O to opposite side MN.
Perpendicular OP will bisect angle MON.
m∠MOP = 25°
By cosine ratio in triangle OPN,
cos(25°) = [tex]\frac{OP}{ON}[/tex]
OP = ON.cos(25°)
OP = 6cos(25°)
OP = 5.438 cm
By sine ratio of angle PON,
sin(25) = [tex]\frac{PN}{ON}[/tex]
PN = ON.sin(25)
= 6sin(25°)
= 2.536 cm
Since, MN = 2(PN)
MN = 5.071 cm
Area of ΔOMN = [tex]\frac{1}{2}(OP)(MN)[/tex]
= [tex]\frac{1}{2}(5.438)(5.071)[/tex]
= 13.788 cm²
Area of sector OMN = [tex]\frac{\theta}{360}(\pi r^{2})[/tex]
Here 'θ' is the angle subtended by the arc MN at the center.
Area of sector OMN = [tex]\frac{50}{360}(\pi )(6^{2})[/tex]
= 15.708 cm²
Area of the shaded region = 15.708 - 13.788
= 1.92
≈ 1.92 cm²
Answer:
Area of the shaded region = Area of sector OMN - Area of isosceles triangle OMN
Drop a perpendicular OP from vertex O to opposite side MN.
Perpendicular OP will bisect angle MON.
m∠MOP = 25°
By cosine ratio in triangle OPN,
cos(25°) = \frac{OP}{ON}ONOP
OP = ON.cos(25°)
OP = 6cos(25°)
OP = 5.438 cm
By sine ratio of angle PON,
sin(25) = \frac{PN}{ON}ONPN
PN = ON.sin(25)
= 6sin(25°)
= 2.536 cm
Since, MN = 2(PN)
MN = 5.071 cm
Area of ΔOMN = \frac{1}{2}(OP)(MN)21(OP)(MN)
= \frac{1}{2}(5.438)(5.071)21(5.438)(5.071)
= 13.788 cm²
Area of sector OMN = \frac{\theta}{360}(\pi r^{2})360θ(πr2)
Here 'θ' is the angle subtended by the arc MN at the center.
Area of sector OMN = \frac{50}{360}(\pi )(6^{2})36050(π)(62)
= 15.708 cm²
Area of the shaded region = 15.708 - 13.788
= 1.92
≈ 1.92 cm²

What is the measure of _Y, in degrees?
y
A. 116°
B. 32°
C. 640
D. Cannot be determined
Answer:
C. 116º
Step-by-step explanation:
Both sides are congruent, so the triangle is an isosceles triangle. So angle Z will have to be congruent to angle X. Add together the two angles, (32 + 32) and subtract the sum from 180º since all triangles add up to 180º.
32 + 32 = 64
180 - 64 = 116
