Answer:
70
Step-by-step explanation:
x is 70
because it is in an alternate interior angle so XCB s 55 . the trianle is an isosceles triangle so XBC is also 55. 55 + 55 = 110 . 180 - 110 = 70

Given that 4, 5x and 16 are the first three terms of geometric progression
Find:
(1)
the possible values of x,
(2)
the sum of the first ten terms if all the terms are positive.
Answers:
x = -8/5 or x = 8/5
Sum of the first ten terms where all terms are positive = 4092
========================================================
Explanation:
r = common ratio
first term = 4second term = (first term)*(common ratio) = 4rthird term = (second term)*(common ratio) = (4r)*r = 4r^2The first three terms are: 4, 4r, 4r^2
We're given that the sequence is: 4, 5x, 16
Therefore, we have these two equations
5x = 4r4r^2 = 16Solve the second equation for r and you should find that r = -2 or r = 2 are the only possible solutions. If r = -2, then 5x = 4r solves to x = -8/5. If r = 2, then 5x = 4r solves to x = 8/5.
-----------------
To find the sum of the first n terms, we use this geometric series formula
Sn = a*(1 - r^n)/(1 - r)
We have
a = 4 = first termr = 2, since we want all the terms to be positiven = 10 = number of terms to sum upSo,
Sn = a*(1 - r^n)/(1 - r)
S10 = 4*(1 - 2^10)/(1 - 2)
S10 = 4*(1 - 1024)/(-1)
S10 = 4*(-1023)/(-1)
S10 = 4092

Equation: 25.50x ≤ 200
7 video games
Step-by-step explanation:
25.50x ≤ 200
S would be the number of video games
25.50x ≤ 200 Divide both sides by 25.50 to isolate x
x ≤ 7.8...
Since he can't buy a fraction of a game, round 7.8 down to get 7 video games

[tex]Jemima \to[/tex] Elm Street
Required
How much more did Jim travel
The question is incomplete, as the resources to calculate the distance covered by both are not given.
To solve a question like this;
First, calculate the distance by both, then subtract the smaller distance
Take for instance, after calculating the distance, you have:
[tex]Jimmy= 850m[/tex]
[tex]Jemima = 500m[/tex]
The difference d is:
[tex]d = 850m - 500m[/tex]
[tex]d = 350m[/tex]
i.e. Jimmy traveled 350m much more

Angle

x
Answer:
x = 136°
Step-by-step explanation:
We can use a theorem to help us.
Theorem:
The measure of an exterior angle of a triangle is equal to the sum of the measures of the remote interior angles.
For exterior angle x, the remote interior angles are z and <CBD.
From the theorem, we get this equation.
x = z + m<CBD
We know z = 52°.
We need to find m<CBD.
Angles CBD and y are a linear pair. They are supplementary, so the sum of their measures is 180°. We are given y = 96°.
m<CBD + y = 180°
m<CBD + 96° = 180°
m<CBD = 84°
x = z + m<CBD
x = 52° + 84°
x = 136°
Answer:
x = 136°
Step-by-step explanation:
∠ABD = y = 96°, ∠ABD + ∠DBC must be equal to 180° because they form a straight angle.
[tex]y + B = 180\\96 + B = 180\\B = 180 - 96 = 84[/tex]
∠BDC = z = 52° and ∠DBC = B = 84.
Angles ∠BDC, ∠DBC, and ∠BCD must have a sum of 180° because the sum of the interior angles in a triangle is 180°.
[tex]180=(180 - y) + 52 + C\\180=(180 - 96) + 52 + C\\180 - (52 + 84) = C\\C = 44[/tex]
The interior angle at C is 44. Line DCE forms a straight line, therefore having an angle of 180°. To find x, the sum of x and interior angle C is 180°.
[tex]180 = C + x\\180 = 44 + x\\x = 180-44\\x = 136\\[/tex]
Angle ∠BCE = x = 136.

Jamie ran the first 2000 meters in 6 minutes. At that rate, how long would it take Jaime to run 5000 meters?
Answer:
15 minutes
Step-by-step explanation:
To figure this out, you can create a ratio. If we say the first 2000 miles is the 1 in the ratio, the ratio would be 1 : 2.5. Since it took 6 minutes for the first 2000, you have to multiply 6 by 2.5 to get your answer of 15 minutes.

What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ 3x² = - 12
Now, We can simplify as;
⇒ 3x² = - 12
Divide by 3;
⇒ x² = - 12/3
⇒ x² = - 4
⇒ x = √- 4
⇒ x = 2i
Thus, The value of solution of the equation is,
⇒ No real solution

the product of two fractions is 2/3. One fraction is 3/5. what is the other fraction
Answer:
10 / 9
Step-by-step explanation:
Let's suppose the other fraction is x. We are given 3 / 5 * x = 2 / 3
We can divide by 3 / 5 on both sides, which is the same as multiplying 5 / 3 on both sides:
5 / 3 * 3 / 5 * x = 2 / 3 * 5 / 3
This simplifies to:
x = 10 / 9
What is an equation of the line that passes through the points (0, -3)(0,−3) and (-5, 3)(−5,3)?
Answer:
y = 6/5 x -3
Step-by-step explanation:
Standard equation of a line is expressed as;
y = mx+b
Slope m = y2-y1/x2-x1
Given the coordinates (0, -3)and (-5, 3)
Slope m = 3-(-3)/-5-0
Slope m = 6/5
Since the line cuts the y axis at y = -3, hence b = -3
GEt the required equation;
Recall that y = mx+b
y = 6/5 x + (-3)
y = 6/5 x -3
This gives the required equation
Answer: −6/5x-3

If p(x) = x 3 + x 2+ root 5 x + root 5 , then find p( – 5 )
Answer:
-100-4√5
Step-by-step explanation:
Given the polynomial expression
p(x) = x³+x²+√5x + √5
p(-5) = (-5)³+(-5)² + √5(-5) + √5
p(-5) = -125 + 25 -5√5 + √5
p(-5) = -100-4√5

B is the midpoint of AC. if AB = x+5 and BC = 2x-11, find the measure of AB
Answer:
2 is the answer
Step-by-step explanation:
Answer:
AB = 21
Step-by-step explanation:
Since B is the midpoint of AC , then
BC = AB
2x - 11 = x + 5 ( subtract x from both sides )
x - 11 = 5 ( add 11 to both sides )
x = 16
Then
AB = x + 5 = 16 + 5 = 21
