A= 7x + 24°
B = 3x + 92
A=
Answers
Answer:
X= 6.4 ∠A=68.8
Step-by-step explanation:
We know that these 2 angle must equal 180 so we use the equation:
180=7x+24+3x+92
OR
180=7x+3x+24+92
Then, we add like terms (both variable and numbers)
180=10x+116
After that, we solve
180=10x+116
-116 -116
__________
64=10x
________
64/10 = x
________
6.4=x
Now that we have found x, we can plug in x to figure out the new equation to find the angle of A (or B).
∠A= 7(6.4)+24
If we solve that, it would be:
∠A=44.8+24
___________
∠A=68.8

Answer:
x=4, y=-2
Step-by-step explanation:
-5x+8y=-36
5x+7y=6
eqn 1+ eqn 2 gives
15y=-30
divide both sides by 15
y=-2, put in eqn 2
5x+7(-2)=6
5x=20 divide both sides by 5

Triangle DEF has vertices D(0,0), E(7,0), and F(3,7).
The altitudes of triangle DEF intersect at point
Answers
Answer:
(3, 1.7)
Step-by-step explanation:
The point at which the vertices of a triangle meet is known as the orthocenter of the triangle. The orthocenter passes through the vertex of the triangle and is perpendicular to the opposite sides.
Two lines are perpendicular if the product of their slopes is -1.
The slope of the line joining D(0,0), F(3,7) is:
[tex]m_1=\frac{7-0}{3-0}=\frac{7}{3}[/tex]
The slope of the line perpendicular to the line joining D and F is -3/7. The orthocenter is perpendicular to the line joining D and F and passes through vertex E(7, 0). The equation is hence:
[tex]y-y_1=m(x-x_1)\\\\y-0=-\frac{3}{7} (x-7)\\\\y=-\frac{3}{7}x+3 \ .\ .\ .\ (1)[/tex]
The slope of the line joining E(7,0), and F(3,7). is:
[tex]m_1=\frac{7-0}{3-7}=-\frac{7}{4}[/tex]
The slope of the line perpendicular to the line joining E and F is 4/7. The orthocenter is perpendicular to the line joining E and F and passes through vertex D(0, 0). The equation is hence:
[tex]y-y_1=m(x-x_1)\\\\y-0=\frac{4}{7} (x-0)\\\\y=\frac{4}{7} x\ .\ .\ .\ (2)[/tex]
The point of intersection of equation 1 and equation 2 is the orthocenter. Solving equation 1 and 2 simultaneously gives:
x = 3, y = 1.7

Every time a variable is touching a number it means it’s multiplying
5x + 8 = ?
If x = 9, you would multiply 5 and 9 which is 45. You then add 45 and 8
45 + 8 = 53
Therefore 5x + 8 = 53

A local charity receives 1/3 of funds raised during a craft fair and a bake sale. The craft fair raised $252.60. The total amount given to charity was $137.45. How much did the bake sale raise?
Answers
Answer:
$159.75
Step-by-step explanation:
137.45/252.60 + x = 1/3
252.60 + x = 412.35
x = 412.35 - 252.60
x = 159.75
Answer:
297.2
Step-by-step explanation:
549.8 ÷ 4 = 137.45
549.8 - 252.60 = 297.2

This table shows information from a survey about the type of coffee people prefer and whether they like it hot or cold.
of the people who prefer mocha, the relative frequency of them preferring it cold is 0.32
of the people who prefer hot coffee, the relative frequency of them preferring a latte is 0.22
The type of coffee that has the highest percentage of people who prefer it cold is a. regular b. mocha c. latte
the answer is not cappuccino!
Answers
Answer:
0.32
.22
regular (capuccino is incorrect)
Step-by-step explanation:
in the mocha column 25 people prefer hot and 12 people prefer cold are equal to 37 people. 25+12=37
relative frequency of preferring cold is 12. 12÷37 = .32
In the hot column 11, 25, 19, 30 people are combined for total of 85 people who prefer hot coffee. 11+25+19+30=85
relative frequency of preferring a latte is 19: 19÷85 = .22
combine regular column for 17 ÷ 28 = .61
combine mocha column for 12÷40 = .30
combine latte column for 20÷39 = .51
combine cappucino column for 27÷57 = .47
The type of coffee that has the highest percentage of people who prefer it cold is regular. (if you combine only the cold column you will end up with cappuccino which is wrong.)

Find the measure of angle x.
Answers
Answer: 110 degrees
Since the 2 unknown angles in the triangle are equal you do (180-40)/2 to find what they are equal to. (It's equal to 70) Now that you have the answer for the two angles, now you can subtract 70 from 180 which gives you 110 degrees and that's your answer
Hope this helped you!
Answer:
x°+x°+40°=180°
2x°=180°-40°
2x°=140°
x°=140°
2
x°=70°
x°=70°
therefore,
x=180°-70°
x°=110°

Step-by-step explanation:
Un coeficiente es un número o símbolo multiplicado por una variable o una cantidad desconocida en un término algebraico, polinomio, una serie o cualquier expresión.
a) 5x² + 4x + 2 = 0
El coeficiente de x² = 5, el coeficiente de x = 4
b) –x² + 3x + 4 = 0
El coeficiente de x² = -1, el coeficiente de x = 3
c) x² - 4x + √7 = 0
El coeficiente de x² = 1, el coeficiente de x = -4
d) x² + 8 = 0
El coeficiente de x² = 1, el coeficiente de x = 0

3x -2y = -6 and y = x+5
Answers
Answer:
x = 4, y = 9.
Step-by-step explanation:
3x -2y = -6 and y = x+5
Substitute y = x + 5 in the first equation:
3x - 2(x + 5) = -6
3x - 2x - 10 = -6
x = -6 + 10
x = 4
So y = 4 + 5 = 9.

Answers
Answer:
2= 95 degrees
3= 25 degrees
1= 60 degrees
5= 25 degrees
4= 95 degrees
Step-by-step explanation:
2) Straight line is 180 degrees so
180-85=95 degrees
3) I got 25 degrees because it's a corresponding angle of X, which is parallel to 25.
1) A triangle is always 180 degrees, 95+25=120 180-120=60
5) Its another corresponding angle to 25
4) Straight line is 180 degrees 60+25=85 180-85=95
Or you could of worked out the bottom 85 and minus it from 180 which will also correspond to 4

Answer:
2.4 cm
Step-by-step explanation:
We know the length of segment AB and the length of segment BC. To find their midpoints, we can divide their length by 2.
Let's find the midpoint of AB.
Segment AB: 10 cm Midpoint of AB: 10/2 = 5 cmNext let's find the midpoint of BC.
Segment BC: 5.2 cmMidpoint of BC: 5.2/2 = 2.6 cmIn order to find the difference between these midpoints, we can subtract the midpoint of AB by the midpoint of BC.
5 cm - 2.6 cm = 2.4 cmTherefore, the difference between the midpoints of AB and BC is 2.4 cm.

The measures of the angles of a triangle are shown in the figure below. Solve for x.
Answers
Answer:
x = 82°
Step-by-step explanation:
The triangle sum theorem states that the sum (total measure) of all angles in a triangle must add up to 180°.
Therefore:
60° + 38° + x° = 180°
98° + x° = 180°
98° – 98° + x° = 180° – 98°
x = 82°
