Answer:
-b-12
Step-by-step explanation:
4b+7-5b-19
4b-5b+7-19
-b+7-19
-b-12
Answer:
-b-12
Step-by-step explanation:
The like terms is 4b and -5b since they both have b so you have to combine like terms. The coefficients are 4 and 5. Then you combine the rest of the like terms which are 7 and -19 and get 12. So once simplify you get the expression -b-12

the angle of a triangle in the ratio 1:3:5 how much is the larger angle
Answer:
100°
Step-by-step explanation:
The sum of all the angles in a triangle is 180°.
This is 1 + 3 + 5 = 9
180 ÷ 9 = 20
The scale factor is 20.
Multiply 5 (the greatest angle) by the scale factor.
5 x 20 = 100
Victor drew a square with vertices at (1,2), (3,2), (3,4), and (1,4). He slides the square 5 units up to create an image. What are the vertices of the image? (1,7), (3,7), (3,9), and (1,9) (6,2), (8,2), (8,4), and (6,4) (1,-2), (3,-2), (3, -4), and (1,-4) (1,-3), (3,-3), (3, -1), and ( 1,-1)
Answer:abcd
Step-by-step explanation:
"If a point (x, y) is shifted 'h' units upwards, coordinates of the image point will be",
(x, y) → (x, y + h)
If the vertices of a square are,
A(1, 2), B(3, 2), C(3, 4), D(1, 4)
If these vertices are shifted 5 units upwards, then the coordinates of the vertices of the image will be,
A(1, 2) → A'(1, 2+5)
→ A'(1, 7)
B(3, 2) → B'(3, 2+5)
→ B'(3, 7)
C(3, 4) → C'(3, 4+5)
→ C'(3, 9)
D(1, 4) → D'(1, 4+5)
→ D'(1, 9)
Therefore, Option (A) will be the answer.

The circumference of a circle is approximately 3.14 times the length of its diameter. Which inequality can be used to find all possible diameter lengths, d, if the circumference of a circle is more than 50 cm? 3.14 d less-than 50 3.14 d greater-than 50 50 d greater-than 3.14 50 d less-than 3.14
Answer:
3.14 d greater-than 50
(i also need help with one of my questions >~<)
Step-by-step explanation:
Since the circumference of a circle is approximately 3.14 times the length of its diameter, mathematically speaking:
C = 3.14d
That expression must be greater (>) than 50:
3.14 d > 50
So, the correct option is; 3.14 d greater-than 50

He measures and determines that he needs 24 feet of fencing. When he arrives at home improvement store, he realized fencing is priced at $0.25 per inch how much will it cost to fence it
Answer:
It will cost 72 dollars to fence the perimeter
Step-by-step explanation:
First of all, we will have to make sure that we are working with the same units.
To do this, we will have to convert our units which are given in feet to inches.
1 foot = 12 inches
24 feet = 288 inches.
We now have the total length of what he needs to be 288 inches.
The fence costs 0.25 dollars per inch.
Therefore 288 inches will cost 0.25 X 288 = $ 72
find the nth term of the following sequence
-7 ,-4 , -1 , 2 ,5
Answer:
3n - 10
Step-by-step explanation:
Find the difference between the terms
-7 , -4 , -1, 2, 5
+3 +3 +3 +3
Difference of terms = 3, so you'd write that as 3n
Then you'd need to find the difference between the 1st term and 3:
3 > -7
- 10
So you'd write that as 3n - 10

A square wall is covered with sqare tiles. There are 85 tiles altogether along the two diagonals. How many tiles are there on the whole wall?
Answer:
There are 1849 tiles on the whole wall.
Step-by-step explanation:
If there are 85 tiles along the two diagonals, we can use the following rule:
[tex]\frac{85+1}{2}=43[/tex]
So we have 43 tiles in the first diagonal and 85-43 = 42 in the second diagonal.
Now, as we have a square the side will have 43 tiles so the total area will be cover with:
[tex]A=43*43=1849[/tex]
Therefore, there are 1849 tiles on the whole wall.
I hope it helps you!

Answer:
4K^4
Step-by-step explanation:
Answer:
4k^4
Step-by-step explanation:
Just break it down step by step. The cube root of 64 is 4, since 4*4*4 = 64.
The cube root of k^12 is k^4, since k^4*k^4*k^4 = k^12 (since you add the exponent together when multiplying.
So, when you put this together, the cube root must be 4k^4.

9514 1404 393
Answer:
4
Step-by-step explanation:
The median of a data set with an even number of members is the average of the middle two. We are told that is 6. The average of the whole set of 4 integers will be the average of the averages of the middle two and the two others.
In other words, the average of 6 and the number you're looking for is 5. That means the number you're looking for is x, where ...
(x +6)/2 = 5
x +6 = 10
x = 4
The mean of the largest and smallest integers is 4.

Answer:
hope you like my question
Step-by-step explanation:
Hi -
What you want to do here is solve the equation by substitution.
To do that, you solve one of the equations for y. then plug that into the other equation so you have an equation with only x as the variable.
1) Solve either equation for y. Lets go with the first one:
4x+5y=102
Subtract 4x from each side:
5y=102-4x
Divide both sides by 5
y=(102-4x)/5
2) Plug this value for y into the other equation we started with:
7x+5y = 126
7x + 5((102-4x)/5) = 126
3) Solve the resulting equation for x.
Since we are multiplying and dividing (102-4x) by 5 the 2 5s cancel each other out
7x + 5((102-4x)/5) = 126
7x + 102 - 4x = 126
Combine the 2 x terms:
3x+102=126
subtract 102 from each side:
3x = 24
Divide both sides by 3:
x=8
Once we have a value for x, we can plug that number into either one of our starting equations to solve for y.
4x + 5y = 102; if x = 8
32+5y = 102
subtract 32 from each side:
5y = 70
Divide both sides by 5:
y = 14
So x = 8 and y = 14.
You can check your work by plugging these numbers both into your 2 initial equations.
4x+5y=102; 4*8+5*14 = 102
7x+5y=126; 7*8 +5*14 = 126

A rectangle has a perimeter of 56 cm and an area of 96cm^2. Its length is 4 more than five times its width. What is the lenght and width of the rectangle?
Answer:
L= 24cm
W= 4cm
Step-by-step explanation:
Given data
Perimeter= 56cm
Area= 96cm^2
Let the width be x
W= x cm
L= 5x+4
P=2L+2W
56= 2(5x+4)+2x
56= 10x+8+2x
56-8= 12x
48= 12x
x= 48/12
x= 4cm
L= 5x+4
L= 5(4)+4
L= 20+4
L= 24cm
