what is the answer of -6n-2n=16
Answer:
n = - 2
Step-by-step explanation:
Given
- 6n - 2n = 16, that is
- 8n = 16 ( divide both sides by - 8 )
n = - 2
Step-by-step explanation:
-6n-2n=16
-6n+-2n=16
(-6n+-2n)=16
-8n=16 divide both sides by - 8
-8n÷-8= 16÷ - 8
n= - 2
Triangle WXY is isosceles. ∠YWX and ∠YXW are the base angles. YZ bisects ∠WYX. m∠XYZ = (15x)°. m∠YXZ = (2x + 5)°. What is the measure of ∠WYX? 5° 15° 75° 150°
The measure of ∠WYX in the given isosceles triangle is; 150°
Angles in a triangleWe are told that Triangle WXY is isosceles..
We are given the base equal angles as;
∠YWX∠YXWYZ bisects ∠WYX and m∠XYZ = (15x)°. Thus;
∠WYX = 2(15x)° = (30x)°
Now, we are told that m∠YXZ = (2x + 5)°
Thus, since sum of angles in a triangle is 180°, then;
30x + (2x + 5)° + (2x + 5)° = 180
34x + 10 = 180
34x = 170
x = 170/34
x = 5
Thus;
∠WYX = (30x)° = (30 × 5) = 150°

Bess and Gina earn $45 per week for delivering flowers. Bess worked for x weeks and earned an additional total bonus of $20. Gina worked for y weeks. Which expression shows the total money, in dollars, that Bess and Gina earned for delivering flowers?
45x + 20 + 45y
65x + 45y
45x − 20 + 45y
45x + 65y
\
Answer:
45x +20 +45y
Step-by-step explanation:
Let
x -----> the number of weeks worked by Bess
y ----> the number of weeks worked by Gina
we know that
The total money earned by Bess and Gina for delivering flowers, is equal to the sum of the number of weeks worked by Bess and Gina. all multiplied by the weekly rate of $45 plus an additional total bonus of $20
so
The expression that represent this situation is

A farmer saw some chickens and pigs in a field. He counted 30 heads and 84 legs. Determine exactly how many chickens and pigs
he saw?
Answer:
51
Step-by-step explanation:
Given parameters:
Number of heads = 30 heads
Number of legs = 84 legs
Unknown:
Number of chickens and pigs = ?
Solution:
Since a chicken has one head, the number of chicken is the same as the number of heads;
Number of chicken = 30
A pig has 4 legs,
Number of pigs = [tex]\frac{84}{4}[/tex] = 21pigs
Total number of pigs and chickens = 30chickens + 21 pigs = 51
12w+10=2(3w+35)
How do I solve this?
Answer:
w = 10
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
12w + 10 = 2(3w + 35)
Step 2: Solve for w
Distribute 2: 12w + 10 = 6w + 70Subtract 6w on both sides: 6w + 10 = 70Subtract 10 on both sides: 6w = 60Divide 6 on both sides: w = 10Step 3: Check
Plug in w to verify it's a solution.
Substitute: 12(10) + 10 = 2(3(10) + 35)Multiply: 120 + 10 = 2(30 + 35)Add: 130 = 2(65)Multiply: 130 = 130Here we see that 130 does indeed equal 130.
∴ w = 10 is a solution of the equation.
Step-by-step explanation:
Solve this equation by isolating for w.

Answer:
P = 10y - 3Step-by-step explanation:
Perimeter is the sum of all the sides
P = 3y - 2 + 2y + 2 + 2y - 2 + y + 2y - 1 =10y - 3Answer:
P = 10y - 3
Step-by-step explanation:
Perimeter is dettermined by adding all the outside surfaces information together.
Watch:
First, set up:
(3y - 2) + (2y + 2) + (2y - 2) + (y) + (2y - 1)
Now add the common alikes.
(3y + 2y + 2y + y + 2y) = 10y
(-2 + 2 - 2 - 1) = -3
Now you have your perimeter.
P = 10y - 3

Step-by-step explanation:
Answer:
1. e ≥ -2
2. c ≤ 4
3. x < 1.5 or 1 5/10
Step-by-step explanation:
1. -3e-10 ≤ -4 => first add 10 to both sides
+10 +10
-3e ≤ 6 => Then divide negative three on both sides.
/-3 /-3
e ≥ -2 => Since, we divided by a negative the sign switches.
2. 8c+4 ≤ 4(c-3) => First, Distribute the 4.
8c+4 ≤ 4c -12 => Next, Subtract 4 on both sides.
8c ≤ 4c -16 => then, subtract 4c on both sides.
-4c 4c
4c ≤ 16 => Finally, you divided 4 on both sides.
/4 /4
c ≤ 4
3. 5(x-1) < 3x +10 -8x => First, you add like terms.
5(x -1) < -5x +10 => Next, you distribute the 5.
5x -5 < -5x +10 => Then, you add five in both sides.
+5 +5
5x < -5x +15 => After that you add -5x in both sides.
+5x +5x
10x < 15 => Finally, you divide 10 in both sides.

Find the x and y intercepts for the equation 2x + 7y = 42.
Answer:
see explanation
Step-by-step explanation:
Given
2x + 7y = 42
To find the x- intercept let y = 0 in the equation and solve for x
2x + 7(0) = 42, that is
2x = 42 ( divide both sides by 2 )
x = 21 ← x- intercept or (21, 0 )
To find the y- intercept let x = 0 in the equation and solve for y
2(0) + 7y = 42 , that is
7y = 42 ( divide both sides by 7 )
y = 6 ← y- intercept or (0, 6 )

10x - (2x + 9) = -3 (15 - 4x)
Answer:
x=9
Step-by-step explanation:
First, distribute the negative sign, changing (2x+9) to -2x-9
next, distribute. 10x+−2x+−9=(−3)(15)+(−3)(−4x)
then, combine like the like terms (10x+−2x)+(−9)=12x−45
then you get 8x+−9=12x−45, and you will subtract 12x from both sides, resulting in −4x−9=−45. To get -4x by itself, add 9 to both sides
lastly, divide both sides by -4
x=9
Answer:
x = 9
Step-by-step explanation:
Distribute
10x - (2x + 9) = -3 (15 - 4x)
10 − 2 − 9 = − 3 (15 − 4)
Combine like terms
8 − 9 = − 3 (15 − 4 )
Rearrange terms
8 − 9 = − 3 (− 4 + 15)
Distribute
8 − 9 = 12 − 45
Add 9 to both sides of the equation
8 − 9 + 9 = 12 − 45 + 9
If the point of the preimage is (5,2) and the point of the image is (1,2), what RULE was applied to the preimage to obtain the image?
A) (x, y + 4)
B) (x + 4, y)
C) (x - 4, y)
D) (x, y - 4)
Explanation:
We have x = 5 turn into x = 1. We need to subtract 4 from the x coordinate to get this. Therefore x turns into x-4.
The y coordinate stays at y = 2 the entire time, so y isn't altered. We have y map to y.
Overall, the rule is [tex](x,y) \to (x-4, y)[/tex] which translates the point 4 units to the left.

2. How long is 10% of 60 minutes?
3. How long is 75% of 60 minutes?
(please provide explanation for both)
Answer:
6 minutes
45 minutes
Step-by-step explanation:
There are a few ways I solve problems with percentages. First... it is easy to find 10% of 60 because you just divide 60 minutes by 10 to find the answer. (you do this because 10% is 100% divided by 10)
If you know what 10% of 60... (6) and you are trying to find 75%... all you have to do is multiply the 10% value by 7 to find 70%...if you do this... you get 70% = 42 minutes.
To find the remaining 5%.... just add half of the 10% value to 42 minutes. (1/2 of 6 = 3)
42 + 3 = 45
I really hope this helped
2. 10% of 60 minutes long, means duration of 6 minutes.
3. 75% of 60 minutes long, means duration of 45 minutes.
What is percentage?The percentage is a mathematical term, which means a number or a ratio which represented in fractions of 100. we use '%' symbol to represent percentage.
Formula for percentage;
Percentage = (present quantity/whole quantity)×100
2. The duration of, 10% of 60 minutes is,
⇒ T/60×100 =10
⇒ T = 6 minutes
3. The duration of, 10% of 60 minutes is,
⇒ T/60×100 =75
⇒ T = 45 minutes
