Answer:
B
Step-by-step explanation:
A team of seven workers started a job, which can be done in 11 days. On the morning of the fourth day, several people left the team. The rest of the team finished the job in 14 days. How many people left the team?
Let x be the number of people who left the team.
(Hint: Focus on the work left after several workers left. )
Answer:
3 people leftStep-by-step explanation:
The job can be completed by 7 people in 11 daysThe job is equivalent of 7*11 = 77 people*daysAfter 3 days, job left:
(11 - 3)*7 = 56 people*daysThis was completed by 7 - x people as x people left
Time needed was 14 days, we have new equation:
14(7 - x) = 567 - x = 4x = 7 - 4x = 3As we found, 3 people left
Find the value of x.
Given:
Figure of a triangle.
To find:
The values of x.
Solution:
In the figure, we have an angle bisector.
According to the angle bisector theorem, an angle bisector of a triangle always divides the opposite side into two segments that are proportional to the other two sides of the triangle.
Using angle bisector theorem, we get
[tex]\dfrac{x}{7}=\dfrac{15}{14}[/tex]
Multiply both sides by 7.
[tex]x=\dfrac{15}{14}\times 7[/tex]
[tex]x=\dfrac{15}{2}[/tex]
[tex]x=7.5[/tex]
Therefore, the value of x is 7.5 units.

Write an equation of the line that passes through the given points. (-1,7) and (3,-5)
Answer:
y=-3x+4
Step-by-step explanation:
First, let's find the slope (m)
(-1,7), and (3,-5)
the formula is: (y2-y1)/(x2-x1)
we can label the points.
x1=-1
y1=7
x2=3
y2=-5
substitute into the equation
m=(-5-7)/(3--1)
m=(-12)/4
m=-3
Now let's use the equation for point-slope form, which is y-y1=m(x-x1)
using the labeled points from above:
y-7=-3(x+1)
do distributive prop
y-7=-3x-3
add 7 to both sides
y=-3x+4

Answer:
7x10*9
Step-by-step explanation:
3x-2y=1x+4y=33 elimination process
Answer:
x = 5 ; y = 7
Step-by-step explanation:
3x - 2y = 1 --------------------(I)
x + 4y = 33 ------------(II)
Multiply equation (II) by (-3) and then add. So, x will be eliminated and we can find the value of y
(I) 3x - 2y = 1
(II)*(-3) -3x -12y = -99 {Now add}
- 14y = -98
y = -98/14
y = 7
Plugin y = 7 in equation (I)
3x - 2*7 = 1
3x - 14 = 1
3x = 1 + 14
3x = 15
x = 15/3
x = 5

What is the solution to −6x−4≥−2(x−4) ?
x≤−3
x≥3
x≥2
x≤−1
Answer:
The correct answer is: Option 1: x≤-3
Step-by-step explanation:
Given inequality is:
[tex]-6x-4\geq -2(x-4)[/tex]
First of all, we will distribute -2 into the bracket
[tex]-6x-4\geq -2x+8[/tex]
Then we will add 4 on both sides
[tex]-6x-4+4\geq -2x+8+4\\-6x \geq -2x+12[/tex]
Adding 2x on both sides
[tex]-6x+2x\geq -2x+12+2x\\-4x\geq 12[/tex]
Dividing both sides by 4
[tex]\frac{-4x}{4} \geq \frac{12}{4}\\-x \geq 3[/tex]
As there should be only x on the left side of the inequality we will multiply the inequality with -1.
Multiplying the inequality with -1 reverses the sign of inequality
So,
[tex]x \leq -3[/tex]
Hence,
The correct answer is: Option 1: x≤-3
-X - 8x + 7

16 – (3 – 4y) = 2(y + 2)
Answer:
[tex]y = -4\frac{1}{2}[/tex]
Step-by-step explanation:
[tex]16-(3-4y) = 2(y+2)[/tex]
Distribute.
[tex]16 - 3 + 4y = 2y + 4[/tex]
Combine like terms.
[tex]13 + 4y = 2y + 4[/tex]
Subtract [tex]2y[/tex] from both sides.
[tex]13 + 2y = 4[/tex]
Subtract 13 from both sides.
[tex]2y = -9[/tex]
Divide both sides by 2.
[tex]y = -4\frac{1}{2}[/tex]

Help me out with 5,6,7 (Geometry)
Problem 5
A counterexample could be a number like 6. Divide it over 2 and we get 6/2 = 3, which is a whole number. This shows 6 is a multiple of 2. However, 6/4 = 1.5 is not a whole number, so 6 is not divisible by 4. The overall claim is false.
======================================================
Problem 6
Let's say we are subtracting a positive number and a negative number. For instance, let's say we're subtracting 10 and -7
So,
10 minus -7 = 10 - (-7) = 10+7 = 17
When subtracting a negative, the two minus signs cancel to form a plus sign. The result we get is 17, which is larger than the greater number 10. So this is one counterexample that proves the claim to be false.
======================================================
Problem 7
Start with a circle. The circle can be any size. Plot four random points on the circle. The points can be anywhere you want. Let's label those points A,B,C,D. Form quadrilateral ABCD.
Now let's say we pick point A and pull it off the circle and pull it outside the circle. Points B,C and D remain on the circle. This is one example where we cannot draw a circle through this new arrangement of points. The circle goes through B,C, and D just fine; however, it doesn't go through point A. If you try to attempt to get the circle to go through A, then you'll have to pick B,C or D to ignore. In other words, you'll only be able to pick three points that the circle can go through. Therefore, a circle cannot be drawn as described for every quadrilateral.
Note: Any quadrilateral that has all four points on the same circle is known as a cyclic quadrilateral.
a local club lottery offers a standard prize of $50 and there is one drawing each week. If there is no winner drawn, the prize triples for the following week. This pattern continues until the prize is won. If no wins in the first 5 weeks, how much will the prize be for week 6?
Answer:
300
Step-by-step explanation:
Every week you add 50 so 50x6 is 300
