Answer:
B
Step-by-step explanation:
what is 4x-2=3(x-3)
Answer:
x = -7
Step-by-step explanation:
4x - 2 = 3(x - 3)
use the distributive property
4x - 2 = 3x - 9
+9 +9
4x + 7 = 3x
-4x -4x
7 = -1x
x = -7

Answer:
D) 53°
Step-by-step explanation:
All interior angles of any triangle add up to 180°
? = 180° - 43° - 84°
? = 53°
Answer:
Its B. 53
Step-by-step explanation:
To find the unknown angel you need to add the number you already have AKA 43 and 84 you need to add up to 180 so 43+84+53= 180
In a triangle, JKL,< J measures 35 degrees and k is a right angle. What's the measure of l.
Answer:
55°
Step-by-step explanation:
180 - 35 - 90 = 55°
Answer:
55 degrees
Step-by-step explanation:
Hello There!
If you didn't know the measure of all of the angles in a triangle have a sum of 180
So to find a missing angle we subtract the two given angles from 180
We are given that one angle = 35 degrees
and another angle is a right angle
(a right angle measure 90 degrees)
Given this information we can find the missing angle of I
angle I = 180 - 90 - 35
180 - 90 - 35 = 55
so we can conclude that the measure of angle I is 55 degrees

Answer:
y = 1/2x + 2
Step-by-step explanation:
Perpendicular slope = 1/2
( -2, 1)
y - y1 = m(x - x1)
y - 1 = 1/2(x + 2)
y - 1 = 1/2x + 1
y = 1/2x + 2
Answer:
y1=+/2/5+1
y1+/15
/1=+5/36
-2=1/-/12

What is the difference in the mean absolute deviation for the average temperatures ?
Answer:Mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean. Mean absolute deviation is a way to describe variation in a data set. Mean absolute deviation helps us get a sense of how "spread out" the values in a data set are.

A store manager decides to clear out
school supplies to make room for new
inventory. Now a $20 bookbag will be
on sale for only $9. What is the
discount, as a percentage?
A:55%
B:40%
C:45%
D:50%
Answer:
it would be A:55%
Step-by-step explanation
For percent, to make it easier try to turn it into a 100.
20x5=100
do the same to the 9.
9x5=45.
Now subtract 45 from 100.
100-45=55.
There was a discount of 55%.

Type your answer as a mixed number
4 times as much as the sum of 1/5 and 2/3
Answer: 3 7/15
Step-by-step explanation: You first do 1 /5 plus 2/3.But they don't have the same denominator so you make it the same which you can make it to 15 so you make both denominator of 1/5 and 2/3. So 1 /5 change to 3/15 and 2/3 change to 10/15.Now add 3/15 to 10/15 which is 13/5.After that you do 4 times 13/5.But change 4 to a fraction to make it easy which is 4/1.Now multiply 4/1 by 13/5 which gives you 52/15 .Finally change 52/15 to a mixed number which is 3 7/15.

Kenji walks 44 feet in 10 seconds. At this rate, how many miles does Kenji walk in an hour? Show your work. (1 mile 5 5,280 feet) (make it simple)
Answer:
3 miles
Step-by-step explanation:
1 hour = 3,600 seconds (3,600 ÷ 10 = 360)
360 x 44 = 15,840 Feet
1 mile = 5,280 feet
15,840 feet ÷ 5,280 feet = 3 miles
Kenji walks 3 miles in 1 hour.
Hopefully this helps :3 sorry if wrong :( plz mark brainiest if correct :D Your bootiful/handsome! Have a great day luv <3

Prove that the sum of three successive even integers is always a multiple of 6.
Answer:
if you see three consecutive numbers you can figure out that at least one of them is divisible by 6
Step-by-step explanation:
you can use mathematical induction by proving it mathematically. for a number to be divisible by 6, it should be divisible by 2. Since all are even numbers the number will be divisible by 2.

Stacia walked a total of 30,375 feet. If 2 miles is 10,560 feet, how far did Stacia walk in miles?
Answer:
62
Step-by-step explanation:
Answer:
I believe the answer is 5.8 miles
Step-by-step explanation:
I believe this is the correct answer, although it is possible I am wrong.
This is how I solved this problem:
I divided 10,560 feet by 2, which equals 5280 feet in a mile
Then I divided 30,375 feet by 5280 feet to get 5.7528409
Since there is no way this is the correct simplification, you need to round to the nearest tenth.
5.7528409 is about 5.8 miles
The cost of 3 DVD's and 4 CD's is £62.00. The cost of 4 DVD's and 3 CD's is £64.00. Find the cost of each.
Help!!!
Answer:
the cost of each is £10 and £8 respectively
Step-by-step explanation:
Let us assume the cost of per DVD be x
And the cost of per CD be y
Now as per the question
The following equations should be made
3x + 4y = £62.00
4x + 3y = £64.00
Now multiply by 4 in equation 1 and 3 in equation 2
12x + 16y = £248
12x + 9y = £192
7y = £56
y = £8
Now put the value of y in any of the above equation
3x + 4( £8) = £62
3x + £32 = £62
3x = 30
x = £10
Hence, the cost of each is £10 and £8 respectively
How many cubes of edge 4cm, each can be cut out from cuboid whose length, breadth and height are 20 cm, 18 cm and 16 cm respectively.
Answer:
90 cubes.
Step-by-step explanation:
First we find volume of the cuboid.
Volume = l x b x h = 20 x 18 x 16 = 5760 cm³
Now,
Volume of a single cube = l³ = 4³ = 64
No of cubes that can be cut out from the cuboid is
= Volume of cuboid/ volume of cube
= 5760/ 64
= 90 cubes
Write the equation of b with center b(-2,3) and radius 10.
Answer:
(x+2)^2+(y-3)^2=100
Step-by-step explanation:
so the equation is (x-h)^2+(y-k)^2=r^2
(h,k)=center
r^2=radius
in this case (h,k)=(-2,3)
r^2=r^2
10^2=100
(x-(-2))^2+(y-3)^2=100
Hope fully that helps :)

Yolanda created a scatter plot of the relationship between the number of times she visited different friends each month, y, and the distance in miles of the friends from her home, x. She calculated the equation of the trend line to be y = −3.5x + 20. Use this information to predict the number of times in one month Yolanda would visit a friend who is 4 miles from her home.
Answer:
6 times
Step-by-step explanation:
y = −3.5x + 20 ; x = 4
y = -3.5(4) + 20
y = -14 + 20
y = 6

The first four terms of a sequence are shown below:
9, 5, 1, −3
Which of the following functions best defines this sequence?
A.) f(1) = 9, f(n + 1) = f(n) − 4; for n ≥ 1
B.) f(1) = 9, f(n + 1) = f(n) + 4; for n ≥ 1
C.) f(1) = 9, f(n + 1) = f(n) − 5; for n ≥ 1
D.) f(1) = 9, f(n + 1) = f(n) + 5; for n ≥ 1
Answer:
A.) f(1) = 9, f(n + 1) = f(n) − 4; for n ≥ 1
Step-by-step explanation:
The first four terms of a sequence are shown below.
Let
f(1) = 9
f(2) = 5
f(3) = 1
f(4) = -3
Therefore we know that
f(2) - f(1) = 5 - 9
f(2) - f(1) = - 4
f(2) = f(1) - 4
f(3) - f(2) = 1 - 5
f(3) - f(2) = - 4
f(3) = f(2) - 4
f(4) - f(3) = -3 - 1
f(4) - f(3) = - 4
f(4) = f(3) - 4
Hence the answer is A.) f(1) = 9, f(n + 1) = f(n) − 4; for n ≥ 1
