Answer:
x = 4
Step-by-step explanation:
The angle markings at the bottom of the triangle mean they are congruent. Since they are the only two congruent to each other, that means this triangle is an isosceles triangle.
In an isosceles triangle, not only are the bottom angles congruent, their opposing sides are congruent as well. In this instance, that means 9x - 8 = 28. Knowing that we can solve for x.
[tex]9x-8=28\\\\9x-8+8=28+8\\\\9x=36\\\\\frac{9x}{9}=\frac{36}{9}\\\\x=4[/tex]
Answer:
x = 4Step-by-step explanation:
9x - 8 = 28 ( converse of isosceles triangle )
(If two angles of a triangle are congruent , then the sides opposite to these angles are congruent.)
[tex]9x - 8 = 28 \\ 9x - 8 = 28 + 8 \\ 9x = 36 \\ \frac{9x}{9} = \frac{36}{9} \\ x = 4 \\ [/tex]

After the first four games of a professional football season, three players scored a total of 80 touchdowns.
Duke Johnson scored 14 of the touchdowns.
Josh McCown scored 40% of the touchdowns.
Andre Roberts scored the remaining touchdowns.
How many touchdowns did Andre Roberts score?
A.20 touchdowns
B.28 touchdowns
C.32 touchdowns
D.52 touchdowns
Answer:
b
Step-by-step explanation:
Andre Roberts scored a total of 34 touchdowns
An equation is an expression that shows the relationship between two or more variables and numbers.
The total touchdowns is 80.
Duke Johnson scored 14 of the touchdowns.
Josh McCown scored 40% of the touchdowns. = 40% of 80 = 0.4 * 80 = 32
Let x represent the number of touchdowns scored by Andre Roberts, hence:
x + 14 + 32 = 80
x + 46 = 80
x = 34
Andre Roberts scored a total of 34 touchdowns

Please help, we're supposed to be writing an equation from the table here. But I don't know.
Answer:
y = 3x - 3
Step-by-step explanation:
This more of a guess than a reality of method. You have to try and guess which number when multiplied by 4 will give 9. It won't happen directly.
The best clue is provide by (0,-3).
So let's start with a general linear equation.
y = mx + b
If you put in 0 for x then mx disappears and you are are left with y = - 3
That means that b = - 3
So now you have
y = mx - 3
Now try another one
y = mx - 3
y = 9
x = 4
9 = mx - 3
9 = 4m - 3 Add 3 to both sides
9+3 = 4m-3+3 Combine
12 = 4m Divide by 4
12/4 = 4m/4
3 = m
So the equation you want so far, is y = 3x - 3 Does it work for anything else?
Try - 3 , - 12 . If it works for this, it should work for anything.
y = 3*-3 - 3
y = -9 -3
y = - 12
and it does work, so that's your answer.
Hanna has 88cm of ribbon and cuts it in the ratio 5 : 6. How much longer is the longest piece and the shortest piece?
Answer:
8 cm
Step-by-step explanation:
sum the parts of the ratio, 5 + 6 = 11 parts
Divide the length of ribbon by 11 to find the value of one part of the ratio
88 cm ÷ 11 = 8 cm ← value of 1 part of the ratio , then
5 parts = 5 × 8 cm = 40 cm
6 parts = 6 × 8 cm = 48 cm
Then difference between lengths is 48 cm - 40 cm = 8 cm
longer piece is 8 cm longer than shortest piece.
Graph x + 3y = 6.
please help
this is the photo of a answer
Answer:
see attached
Step-by-step explanation:
Both coefficients are divisors of the constant, so the intercepts are integer values. This makes it easy to graph the line using the x- and y-intercepts.
x-intercept
Set y=0 and you get ...
x = 6
y-intercept
Set x=0 and you have ...
3y = 6
y = 2 . . . . divide by 3
__
The intercepts (6, 0) and (0, 2) are points on the line. Plot these points and draw the line through them.
1/9 (2m - 16) = 1/3 (2m + 4)
Please follow the steps in the picture!
Answer:
1/9 (2m - 16) = 1/3 (2m + 4)
expand
2/9m- 16/9 =2/3m +4/3
move m to other side
- 16/9 =2/3m (-2/9m) +4/3
simplify
- 16/9 =(6-2)/9m +4/3
- 16/9 =4/9m +4/3
move 4/3 to other side
- 16/9 -4/3 =4/9m
- 16/9 -12/9 =4/9m
-28/9 = 4/9m
multiply by 9
4m= -28
m= -7

If the sum of the roots of the equation 3x² + kx + 1 = 0 is 7. then what the value of k
Answer:
The value of k is -21
Step-by-step explanation:
ax² + bx + c = 0
Sum of the roots = -b/a
3x² + kx + 1 = 0
= sum of the roots = -k/3
-k/3 = 7
Now, Multiply both side by (-3) we get,
(-3)-k/3 = 7(-3)
k = -21
Thus, The value of k is -21

Find the value of X and prove the following
The value of the variable x can be determined using the circle theorem to
determine the angle formed by x.
The correct responses are;
(1) x = 30°(2) x = 100°(3) x = 60°Reasons:
(1) From circle theorem, we have;
Equal chords subtends equal arcs and vice versaEqual chords subtend equal angles at the center of a circleTherefore;
Angle subtended by [tex]\displaystyle \widehat {AB}[/tex] at center = Angle subtended by [tex]\widehat {BC}[/tex] at the center;
Angle at the center = 2 × Angle at the circumferenceTherefore;
Angle subtended by [tex]\displaystyle \widehat {AB}[/tex] at the circumference = Angle subtended by [tex]\mathbf{\widehat {BC}}[/tex] at the circumference
Which gives;
x = 30°(2) [tex]\displaystyle \widehat {AB} = \mathbf{\widehat {CD}}[/tex] given
Angle subtended by arc [tex]\widehat {CD}[/tex] at the center = x
Equal arcs subtend equal angles at the center of a circle.
Therefore;
Angle subtended by arc [tex]\mathbf{\widehat {AB}}[/tex] at the center = x
Angle at center = 2 × angle at circumference
Therefore;
x = 2 × 50° = 100°
x = 100°
(3) [tex]\displaystyle \widehat {AC} = \mathbf{ 3 \times \widehat {AB}}[/tex] given
By definition, we have;
Angle subtended by [tex]\widehat {AC}[/tex] at the center = 3 × Angle subtended by [tex]\widehat {AB}[/tex] at the center
According to circle theorem, we have;
Angle at the center = 2 × Angle at the circumference
Let y represent the angle subtended at the circumference by [tex]\widehat {AB}[/tex], we have;
y = 20°
[tex]\widehat {AB}[/tex] = 2·y
[tex]\widehat {AC}[/tex] = 3 × [tex]\widehat {AB}[/tex] = 3 × 2·y = 6·y
Therefore;
[tex]\widehat {AC}[/tex] = 6 × 20° = 120°
[tex]\widehat {AC}[/tex] = 120°
[tex]\widehat {AC}[/tex] = 2·x
Therefore;
2·x = 120°
[tex]\displaystyle x = \frac{120^{\circ}}{2} = \mathbf{ 60^{\circ}}[/tex]
x = 60°
