Answer:

8/3

Step-by-step explanation:

If we multiply it the subtraction will cut off and 8 will mulitply to 8/3.

Answer:

x = 6

Step-by-step explanation:

measure of angle E: 5(6) + 8 = 38

measure of angle D: 6(6) + 8 = 44

measure of angle C:  180 - 82 = 98

check answers by adding all 3 angle measures to make sure they equal 180 degrees  

Answer:

always

Step-by-step explanation:

no matter what the angles of a rectangle will be 90 degrees so the answer is always

Answer:

Step-by-step explanation:

Consecutive angles are equal only when dealing with a square or a rectangle. All other 4 sided figures do not have this property.

So the answer is sometimes.

Answer:

172.5

Step-by-step explanation:

The formula for the surface area of a right circular cone (the following shape) is πr( r + √h^2 + r^2). Since the radius (r) is already given (3) and the height (h) is already given (15), you just replace each r with 3 and h with 15. After solving this out, you should get 172.45, which rounds to 172.5 to the first decimal place

Answer:

6x-y

Step-by-step explanation:

Add the two expressions

Answer:

6x + -y

Lets simplify this step by step:

2x + 7y + 4x −8y

2x + 7y + 4x + −8y

Then we combine like terms

=2x + 7y + 4x + −8y

=(2x + 4x) + (7y + −8y)

= 6x + −y

Answer:

8.24+6.62=14.86

Step-by-step explanation:

5t-3(7t+1) < 93

Remove the parentheses

5t-21t-3 < 93

-16t < 93+3

-16t < 96

Divide both sides by 16

-t<96/16

-t<6

t > -6

Answer: The inequality t < 6 is the correct answer.

Step-by-step explanation:

5t - 3 (7t + 1) < 93​ <--- This is the original equation.

5t + (7t + 1) - 3 < 93​ <---- Use commutative property.

16t - 3 < 93 <--- Simplify

16t - 3 + 3  < 93​ + 3 <---- Add 3 to both sides,

16t < 96 <--- Simplify and do addition.

[tex]\frac{16t}{16}[/tex] < [tex]\frac{96}{16}[/tex] <--- Divide both sides by 16.

t < 6 <--- is the answer to the inequality.

Hope this helps! :D

Answer:

11x + 8 +8x +12 =27  (drop the parenthesis, there's no actual need for them)

19x +20 =27 (i combined like terms and then subtracted 20 from both sides)

19x = 7  (divide both sides by 19 to get x alone)

x= 7/19 or 0.36842105 (the answer)

Step-by-step explanation:

Answer:

This year, Juanita will have to use $75.

Step-by-step explanation:

Because if 2 shirts is $15, 4 shirts will be $30. $45 is $15 more than $30, so the increase is $15. 2*4 is 8, so that will make it 15*4=60. 60+15=75.

Answer:

Total cost: 486.080$

Step-by-step explanation:

Original Price: 560.000$

Sale: 20%

Discount: 560.000$ * 20% = 112.000$

Discounted Price: 560.000$ - 112.000$ = 448.000$

Tax Rate: 8.5%

Tax: 448.000$ * 8.5% = 38.080$

Tax after Tax: 448.000$ + 38.080$ = 486.080$

Answer:

  38.5°

Step-by-step explanation:

A triangle solver can give an answer easily. The angle is 38.5°.

__

The law of cosines can be written to solve for an unknown angle C opposite side 'c' and flanked by sides 'a' and 'b'.

  C = arccos((a² +b² -c²)/(2ab))

Here, we have a=35, b=48, c=30, so the angle is ...

  C = arccos((35² +48² -30²)/(2·35·48)) = arccos(2629/3360) ≈ 38.515°

The angle the cable makes with the pole is about 38.5°.

Answer: m∠T = 48°

ΔMAT has MA = MT

=> ΔMAT is a isosceles triangle at M

=> ∠A = ∠T = (180° - ∠M)/2

=> x + 20  = (180 - 3x)/2

⇔ 2x + 40 = 180 - 3x

⇔ 5x = 140

⇔ x = 140/5

⇔ x = 28

=> ∠A = ∠T = 28 + 20 = 48°

Step-by-step explanation:

If 2 lines are parallel, their slopes are the same, so all we need to do is plug in the given point and slope in the equation y = mx + b and solve for b.

[tex]-1 = 2(1) + b\\\\-1 = 2 + b\\\\-3 = b[/tex]

The equation of a line in slope-intercept form that goes through (1, -1) and is parallel to the line y = 2x - 4 is [tex]y = 2x - 3[/tex].

Answer:

Volume of a cylinder, V = πr^2h

but r= d/2

therefore, Vol = π(d/2)^2h

from the parameters given,

Vol = π(18/2)^2h

=81πh

Answer:

The temperature on the first day was 10 °F.

Step-by-step explanation:

Let's find the temperature in every single step starting from the fourth day:

[tex]T_{4} = T_{3} - 6 F = 1 F[/tex]          

[tex] T_{3} = 1 F + 6 F = 7 F [/tex]

Then, the temperature of the third day was 7 °F

On the third day:

[tex] T_{3} = T_{2} - 10 F = 7 F [/tex]

[tex] T_{2} = 7 F + 10 F = 17 F [/tex]

Hence, the temperature on the second day was 17 °F.

Now, on the second day:

[tex]T_{2} = T_{1} + 7 F = 17 F[/tex]  

[tex] T_{1} = 17 F - 7 F = 10 F [/tex]

Therefore, the temperature on the first day was 10 °F.

I hope it helps you!                        

Answer:

w<6

Step-by-step explanation:

3w/3 <18/3

You divide that and get w<6.

Answer:

Y=4x-3

Explanation: If we look 2 = 5 We can do 4(2)= 8 -3 = 5 So that the answer and 4(4)= 16-3 = 13 so these are the Y so this is the answer!

-6x-2y=42

x-y=-15

Multiply x-y=-15 by 6 ( eliminate the x first)

6(x-y)=6(-15)

(6)(x)=6x

(6)(-y)=-6y

6(-15)=-90

-6x-2y=42

6x-6y=-90

eliminate x the systems of equations by subtracting

-6x+6x-2y+-6y=42-90

-2y-6y=42-90

-8y=-48

divide both sides by -8 to get y by itself

-8y/-8=-48/8

y=6

Find x by substitution method

use y=6 into one of the system of equations

x-y=-15

x-6=-15

move -6 to the other side

sign changes from -6 to +6

x-6+6=-15+6

x=-15+6

x=-9

answer:

(-9,6)

Answer:

Step-by-step explanation:

If you have written the question correctly, then you don't need to factor it. You only need to remove the brackets.

x + 1 + 6x + 6 + 8

7x + 15 is your final answer.

However, I think the question is

(x + 1)^2 + 6(x + 1) + 8

Let y = x + 1

y^2 + 6y + 8

(y + 2)(y + 4)

(x + 1 + 2 ) ( x + 1 + 4)

(x + 3)(x + 5)

Step-by-step explanation:22 is a factor of 66

Answer:the slope and the y intercept (you can tell there linear if the slope is the same and the y-intercepts are different).

Step-by-step explanation:

Answer:

Sample Response: Linear relationships can be compared using their initial values, or y-intercepts, and their rates of change, or slopes. Initial values can tell you which relationship started with a greater value. Comparing slopes can tell you which relationship is rising or falling faster.
