if angle 1 and angle 2 form a linear pair. if m<1=5x+9 and m<2=3x+11, find the measure of both angles
Answer: [tex]m\angle 1=109\°\\m\angle 2=71\°[/tex]
Step-by-step explanation:
It is important to remember the definition of "Linear pair angles".
By definitiion "Linear pair angles" are two angles which are adjacents and supplementary.
Based on this, we know that the angles [tex]\angle1[/tex] and [tex]\angle2[/tex] are supplementary, which means that they add up to 180 degrees.
So, knowing that:
[tex]m\angle 1=5x+9\\m\angle 2=3x+11[/tex]
We can write the following expression and solve for "x":
[tex](5x+9)+(3x+11)=180\\\\8x=180-20\\\\x=\frac{160}{8}\\\\x=20[/tex]
Therefore, substituting, we get that the measures of the angles [tex]\angle1[/tex] and [tex]\angle2[/tex] are:
[tex]m\angle 1=5(20)+9=109\°\\\\\\m\angle 2=3(20)+11=71\°[/tex]
Measures of both the angles are 109° and 71°. We found the measures of two angles forming a linear pair, then solving the equation 8x + 20 = 180, which gives x = 20. Substituting x finds the angles.
If angle 1 (∡1) and angle 2 (∡2) form a linear pair, their measures add up to 180° because linear pairs are supplementary angles. Given that the measures are m∡1 = 5x + 9 and m∡2 = 3x + 11, we can set up the equation:
5x + 9 + 3x + 11 = 180Combine like terms:
8x + 20 = 180Subtract 20 from both sides:
8x = 160Divide both sides by 8:
x = 20Now, substitute x back into the expressions for
∡1 and ∡2:
Therefore, the measures of the angles are :
∡1 = 109° and ∡2 = 71°.
5. A grocer wishes to mix two kinds of nuts costing
$2.41 per pound and $3.65 per pound to make a
248 pounds of mixed nuts costing $2.51 per pound.
To determine the number of pounds of the $2.41
per pound nuts in the mixture, solve for x in the
equation 2.41x +3.65(248 - x) = 622.48. How
many pounds of the $2.41 per pound nuts should
included in the mixture?
Ans:
The solve for x:
2.41x+3.65(248-x)=622.48
2.41x+3.65×248-3.65x=622.48
2.41x-3.65x+905.2=622.48
-1.24x=622.48-905.2
-1.24x= -282.72
x= -282.72÷ -1.24
x=228
Pounds of nuts nper pound $2.41should be included:
228× $2.41
=549.48
Hope it Helps!
The grocer should include approximately 227.84 pounds of the nuts that cost $2.41 per pound.
The grocer is trying to find the right balance of two kinds of nuts to reach a desired price point for a mix. The equation provided should be solved for x, which represents the number of pounds of nuts costing $2.41 per pound. Here is a step-by-step solution:
Begin with the given equation: 2.41x + 3.65(248 - x) = 622.48.
Distribute 3.65 across the parentheses: 2.41x + 3.65 * 248 - 3.65x = 622.48.
Combine like terms: -1.24x + 904.80 = 622.48.
Subtract 904.80 from both sides of the equation: -1.24x = -282.32.
Divide both sides by -1.24 to find x: x = 227.84.
So, the grocer should include approximately 227.84 pounds of the nuts that cost $2.41 per pound.

Solve for xxx.
-9x+5< 17\quad \maroonC{\text{ AND}} \quad 13x+25<-1−9x+5<17 AND13x+25<−1
To solve the inequalities, isolate x in each. The solution for -9x + 5 < 17 is x > -4/3 and the solution for 13x + 25 < -1 is x < -2. The intersection of these solutions, and thus the solution to the compound inequality, is x < -2.
Explanation:We can solve the inequalities separately, then find the intersection of their solution sets. First, let's solve the inequality -9x + 5 < 17. To do this, we subtract 5 from both sides to isolate the term with x which gives -9x < 12. Finally, we divide both sides by -9, remembering to flip the inequality sign since we divided by a negative. This gives x > -4/3.
The second inequality 13x + 25 < -1 can be solved similarly. Subtracting 25 from both sides will get 13x < -26. Divide both sides by 13 to find that x < -2.
The final answer will be the intersection of the two solutions. Since x < -2 is a stricter condition than x > -4/3, the solution to the compound inequality is x < -2.

The width of a rectangular park is 23.4 yards. What is the perimeter of the park if the length is 2.5 times larger than the width.
Answer:
163.8 yd
Step-by-step explanation:
The perimeter of a rectangle is twice the length added to twice the width.
The width is 23.4 yd.
The length is 2.5 times the width, so to find the length, we multiply the width by 2.5.
length = 2.5 * width = 2.5 * 23.4 yd = 58.5 yd
The length is 58.5 yd.
perimeter = 2 * length + 2 * width
perimeter = 2 * 58.5 yd + 2 * 23.4 yd
perimeter = 117 yd + 46.8 yd
perimeter = 163.8 yd

The length of a rectangle is 6 inches longer than it’s width. The perimeter is 96 inches. Find the dimensions (length and width) is the rectangle
Final answer:
To find the dimensions of the rectangle, we used the perimeter formula and set up equations to solve for the width (21 inches) and length (27 inches), given that the length is 6 inches longer than its width and the perimeter is 96 inches.
Explanation:
To solve for the dimensions of the rectangle when the length is 6 inches longer than its width and the perimeter is 96 inches, we need to set up two equations based on the perimeter formula for a rectangle, which is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width.
Let w represent the width of the rectangle. Then, the length of the rectangle is w + 6 inches. By substituting these into the perimeter formula, we get:
96 = 2(w + 6) + 2w96 = 2w + 12 + 2w96 = 4w + 1284 = 4ww = 21Now that we know the width is 21 inches, we can find the length by adding 6 inches to the width:
Length = Width + 6 = 21 + 6 = 27 inchesTherefore, the dimensions of the rectangle are 27 inches in length and 21 inches in width.
Final answer:
To find the dimensions of the rectangle, we used the perimeter formula and set up equations to solve for the width (21 inches) and length (27 inches), given that the length is 6 inches longer than its width and the perimeter is 96 inches.
Explanation:
To solve for the dimensions of the rectangle when the length is 6 inches longer than its width and the perimeter is 96 inches, we need to set up two equations based on the perimeter formula for a rectangle, which is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width.
Let w represent the width of the rectangle. Then, the length of the rectangle is w + 6 inches. By substituting these into the perimeter formula, we get:
96 = 2(w + 6) + 2w
96 = 2w + 12 + 2w
96 = 4w + 12
84 = 4w
w = 21
Now that we know the width is 21 inches, we can find the length by adding 6 inches to the width:
Length = Width + 6 = 21 + 6 = 27 inches
Therefore, the dimensions of the rectangle are 27 inches in length and 21 inches in width.

find the width and height of an older 40 inch television that has an aspect ratio of 4:3 find the area of this screen
Answer:
768 square inches
Step-by-step explanation:
see attached
The width and height of the 40 inch television with a 4:3 aspect ratio are 32 inches and 24 inches respectively. The area of the screen is 768 square inches.
Explanation:To find the width and height of an older 40 inch television with an aspect ratio of 4:3, we can use the formula:
Width = aspect ratio * height
Since the aspect ratio is 4:3, we divide the width by 4 and multiply by 3 to find the height.
Therefore, the width of the television is 32 inches and the height is 24 inches.
To find the area of the screen, we use the formula:
Area = width * height
Substituting the values, we get:
Area = 32 inches * 24 inches
Therefore, the area of the screen is 768 square inches.

Store B advertises that it is reducing the refrigerator’s price by $150. When Stephanie compares the sale prices of the refrigerator in both stores, she concludes that the sale prices are equal. What is the refrigerator’s original price? Write and solve an equation.
Answer:
150 dollhairs
Step-by-step explanation:
Answer:
Refrigerator’s original price = 1000 $
Step-by-step explanation:
Let the original price of refrigerator be r.
Store A advertises that the refrigerator is on sale for 15% off the original price.
[tex]\texttt{Price of refrigerator in store A = }r-\frac{15}{100}r=0.85r[/tex]
Store B advertises that it is reducing the refrigerator’s price by $150.
Price of refrigerator in store B = r - 150
Stephanie compares the sale prices of the refrigerator in both stores, she concludes that the sale prices are equal
That is
0.85r = r - 150
0.15r = 150
r = 1000$
Refrigerator’s original price = 1000 $

Solve the equation-2x+8=-3x+14
Answer:
x = 6
Step-by-step explanation:
-2x + 8 = -3x + 14
Add 3x to both sides.
x + 8 = 14
Subtract 8 from both sides.
x = 6
Both sides of the equation are equal, the solution [tex]x = 6[/tex] is correct.
To solve the equation [tex]-2x + 8 = -3x + 14[/tex], you can follow these steps:
Move the variables to one side of the equation:
Add 3x to both sides of the equation to get the variables on one side:
[tex]-2x + 8 + 3x = -3x + 14 + 3x[/tex]
Simplify:
[tex]x + 8 = 14[/tex]
Isolate the variable:
Subtract 8 from both sides to isolate [tex]x[/tex]:
[tex]x + 8 - 8 = 14 - 8[/tex]
Simplify:
[tex]x = 6[/tex]
Check your solution:
Substitute [tex]x = 6[/tex] back into the original equation to ensure it satisfies the equation:
[tex]-2(6) + 8 = -3(6) + 14[/tex]
Simplify both sides:
[tex]-12 + 8 = -18 + 14[/tex]
[tex]-4 = -4[/tex]
