pls answer for points and brailliest answer
Answer:
10
Step-by-step explanation:
Let's call Ahmed's number x,
If he multiplies it by 2, it becomes 2xHe then divides it by 5 so it would be 2x ÷ 5The result was 4, so it would be written as 2x ÷ 5 = 4To solve for x,
First, multiply both sides by 5: 2x = 20Finally divide both sides by 2 to get x on its own: x = 10Answer: He was thinking of the number 10You could also work backwards:
If he ×2 then ÷5, you would ×5 then ÷2 (doing the opposite):
4 × 5 = 2020 ÷ 2 = 10Hope this helps!

Answer:
x=70
y=55
Step-by-step explanation:
We can start by finding the opposite angle to 125.
180-125=55
We would use 180 because a line is a straight angle, therefore if you intercept the line both angles would add up to 180.
55 is y because they are equivalent.
the sum of all the angles is always 180 so...
55+55=110
180-110=7

For FHG find the measure of the smallest angle ∠HFG, if m∠GHF = 92° and m∠HGF =72°
will give brailist to correct answer and if you show the work
The sum of the measure of angle of a triangle = 180° .
Given two angles = 92° and 72°
_________________________92° + 72° = 164°
180° - 164° = 16° (Ans)

A train decreased its speed by 72 miles hour in 12 minutes. Find the average change in speed per minute.
Answer:
6 mph
Step-by-step explanation:
The average rate of change of the speed of the train will be 6 miles per hour.
What is speed?Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance travelled by time. The unit of speed in miles per hour.
Given that a train decreased its speed by 72 miles per hour in 12 minutes.
As the train is reducing its speed by 72 miles per hour in 12 minutes the average rate of change of the speed will be calculated by dividing the change by the time.
Rate of change = 72 / 12
Rate of change = 6 miles per hour
Therefore, the average rate of change in the speed of the train will be 6 miles per hour.

no need to explain just answer
Answer:
5
Step-by-step explanation:
The whole angle is 180 degrees.
90 degrees is already taken by the angle dividing the two vertical angles.
So you have 90 degrees left. then you have to subtract 49 from 90 to get the angle of '5t+6'.
So 5t+6 = 41, 41-6 is 35. 35/5 is 5, so t is 5.
I didn't go too far into explaining since you asked to not explain it.

Answer: 270
Step-by-step explanation:
1) Find DE
1 : 6
17 : x
Cross multiply
x = 17 * 6
x = 102
DE = 102
2) Compare the two triangles
1st (ABC)
side = 45
base = 17
2nd (ADE)
side = x
base = 102
[tex]\frac{x}{45} = \frac{102}{17}[/tex]
Cross multiply
17x = 102 x 45
17x = 4590
x = 4590/17
x = 270
AD = 270

Which statement is true about the relationship between the height of the plant and the number of days?
A. This relationship is a function because the plant can be more than one height at a time.
B. This relationship is not a function because the plant can be more than one height at a time.
C. This relationship is not a function because the plant can only be one height at a time.
D. This relationship is a function because the plant can only be one height at a time.
This relationship is a function because the plant body can be of only one particular height at a time.
A function can be defined as a relationship between a set of inputs having only one output each. In other words, a function is basically a relationship between inputs and outputs; where each input is related to only one output at a time. Functions are said to occur when the recorded value of x is varied each time. Since we know that the height of the plant (the x-value) varies by each day, Therefore it is a function.
thus we can conclude that the correct option for the relationship between the height of the plant and the number of days is option D, which tells that this relationship is a function because the plant body can only be of one particular height at a time.

Line j passes through the points (-5,-2)
and (5,4).
Line k passes through the point
(-3,6) and is perpendicular to line j.
Find an equation for line k.
**the answer is probably in slope intercept form.
Answer:
y = - 5/3x + 1
Step-by-step explanation:
Slope of line j = (-2-4)/(-5-5)
Slope = -6/-10 = 3/5
Slope of the perpendicular line k: -5/3
Point of line k: (-3,6)
y-intercept of line k = 6 - (-5/3)(-3) = 6 - 5 = 1
