-5(x-7)<15 solve for x
Answer: X>4
Step-by-step explanation: use distributive property. -5 times X times -7. Subtract -35 from both sides. +35-35 cancels out. Subtract 35 from 15. Divide -5 from both sides. Edit: omg I just realized I didn’t change the sign!
-5x+35<15
-35<15-35
-5x<15-35

Angle x is
Answer:
Angle X is 122°
Step-by-step explanation:
Because it's a 180° line (supplementary angle thm):
180°-58°=122°
Answer:
y = 62
x = 122
Step-by-step explanation:
58 + 60 = 118
118 - 180 = y
118 - 180 = 62
y = 62
x = 180 - 58 = 122

Can a set of data have more than one line of best fit? Why or why not?
2 Answers. It is certainly possible (in mostly silly cases). For example, suppose you sample the same x value twice and get two experimental y values that differ. One such case might be getting the points (0,−1) and (0,1) if we sample x=0 twice.
Answer:
yes because for data you need more than one line.

6) Two boats set off from X at the same
time (below). Boat A sets off on a bearing of 325° and with a velocity of
14 km/h. Boat B sets off on a bearing of 2350 with a velocity of 18 km/h.
Calculate the distance between the boats after they have been travelling
for 2.5 hours. Give your answer to the nearest metre.
A
N
X Х
B
Answer:
The distance between the two boats after 2.5 hours is 57 m.
Step-by-step explanation:
The distance covered by each boat after 2.5 hours are:
speed = [tex]\frac{distance}{time}[/tex]
distance = speed x time
For boat A, speed = 14 km/h and time = 2.5 hrs.
So that,
distance = 14 x 2.5
= 35 km
For boat B, speed = 18 km/h and time = 2.5 hrs.
So that,
distance = 18 x 2.5
= 45 km
The distance between the two boats after travelling 2.5 hours can be determined by applying the cosine rule. Let the distance be represented by x, so that:
[tex]a^{2}[/tex] = [tex]b^{2}[/tex] + [tex]c^{2}[/tex] - 2bc Cos A
[tex]x^{2}[/tex] = [tex]45^{2}[/tex] + [tex]35^{2}[/tex] - 2(45 x 35) Cos [tex]90^{o}[/tex]
= 2025 + 1225 - 3150 (0)
= 3250
x = [tex]\sqrt{3250}[/tex]
= 57.0088
x = 57.0 m
The distance between the two boats after 2.5 hours is 57 m.

3 friends want to go for a hike. (Level 4)They pack enough water to last for 6 hours. 3 more people join the hike.How long will their water last now?
Answer:
3 hours
Step-by-step explanation:
Because first 3 friends have water that last 6 hours when you double the amount of people you get less water, I don't speak good English to explain but you have to subtract 3 from 6 because 3 is amount of people that need water that lasts 6 hours and when you have more people you get less water sooooo you subtract 3 from 6.

Find x, the angle of depression from the top of a lighthouse that is 199 ft above water level to the waterline of a ship 1104 ft off shore. Round your answer to the nearest tenth of a degree.
Answer:
10.2°
Step-by-step explanation:
I'm not sure if my answer is correct and I'm not too good at explaining but I'll try.
The height of the triangle would be 199 ft and it's length would be 1104 ft. Since were looking for the angle of depression, the angle would obviously be outside of our triangle (as shown in the picture). The height and length wouldn't change at all so we can just label the imaginary lines with their corresponding measurements.
The angle that we're looking for is marked in the picture. Since we are given the opposite and the adjacent side, we can use the inverse of tan to figure out our angle, which is 10.2°.
You can also use the "Z" rule and our angle would be where it's shown in the third picture. Nothing would change because our opposite side would still be 199 ft and our adjacent side would still be 1104 ft.

Quadrilateral A'B'C'D'is a rotation of quadrilateral ABCD 180° about the origin.
What is the length of A'B'?
A. 6 units
B. 7 units
C. 3 units
D. 4 units
Answer:
Answer- B, 7 units
Step-by-step explanation:
I took the quiz
A.P.E.X
The length of side A'B' is 7 units, so the correct option is B.
What is the length of A'B'?We know that the side length is invariant under rotations, that means that the equivalent sides of the preimage and the image have equal length, then:
AB = A'B'.
We can see that AB= 7, then we can conclude that the correct option is B.
A'B' = 7 units.

The total cost of a vase of spring flowers at a flower shop depends on the number of flowers ordered. Each flower costs $2.50. Which equation represents the relationship between the total cost, y, to the number of flowers, x?
Answer:
D. y=2.50x
Step-by-step explanation:
Since the equation asks for the total cost of a vase of flowers (y) that goes on the left side. Each flower costs 2.50 and the flower shop depends on the number of flowers ordered, which makes it a variable. Therefore C is wrong because it has 2.50 as a constant.
The ending equation will be y = 2.50x
Written in context this means that the total cost of a vase of flowers is equal to the cost of each flower (2.50) by how many flowers are ordered.

Graph the solution of the inequality on a number line. 2(x - 3) - 5x < x-2
Answer:
good luck with this, i have got a good mark in this lesson back then and i would gladly like to help you miss gilr
Step-by-step explanation:
Option D is representing the inequality 2(x - 3) - 5x < x-2 on the number line.
What is a number line?A number line in elementary mathematics is a representation of a graduated straight line that serves as an abstraction for real numbers, represented by the symbol R."
It is assumed that every point on a number line corresponds to a real number and that every real number corresponds to a point.
Given that the inequality is 2(x - 3) - 5x < x-2. The inequality will be solved as,
2(x - 3) - 5x < x-2
2x - 6 - 5x < x - 2
-3x - 6 < x - 2
-3x - x < 6 - 2
-4x < 4
x > -1

How many solutions will this equation have? 2(x + 4) = 2x + 8
Answer:
None
Step-by-step explanation:
This type of equation is a tautology, it will always be true
We want to see how many solutions does the given equation has.
We will see that the equation has infinite solutions.
The given equation is:
2(x + 4) = 2x + 8
To find how many solutions it has, we need to solve it, we first can distribute the product at the left to get:
2(x + 4) = 2x + 8
2x + 2*4 = 2x + 8
2x + 8 = 2x + 8
Note that we have the exact same thing in both sides, so the value of x can be any real number, and the equation will still be true.
This means that there are infinite solutions for the given equation.

You are offered a job that pays a different amount each day. The
first day, you are paid l¢. The second day you are paid 2¢. The
third day you are paid 4¢. Each day, your pay continues to
double. Write an equation that would describe the amount, in
cents, you would be paid on a particular day.
Answer:
Salary by day = .01 * 2^(n-1)
where n = # of days so
day 1 = .01 * 2^(1 -1) = .01 * 2^0 = .01
day 2 = .01 * 2^(2 -1) = .01 * 2^1 = .02
day 3 = .01 * 2^(3 -1) = .01 * 2^2 = .04
day 4 = .01 * 2^(4 -1) = .01 * 2^4 = .08

Answer:
Volume is 285
Step-by-step explanation:
We start by calculating the area of the base
Mathematically, we have a rectangle as the base
So, the area of the base will be;
3.75 * 8 = 30
We now multiply this by the height to get the volume
we have this as:
