x menos 11 menor que 7. .............................
Answer:
x < 18
Step-by-step explanation:
We have an inequality and are asked to solve.
To solve, we need to isolate x or by other means get x by itself.
X - 11 < 7
Add 11 to both sides :
x < 18
Now you could ask whether the inequality sign would change, no, this would only happen when you divide by a negative number.

Answer: A) 356.48m²
Step-by-step explanation:
divide up the shape:
square:
a=s*s
16*16=256m^2
Semicircle:
a = 0.5*πr²
(r would be half of a square side which is 8)
0.5*3.14*64=100.48
Add up the shapes:
100.48+256=356.48m²
1. Sarah and Maya both need notebooks and pencils. The equation that represents Sarah's
purchases is y = 13- 3x. The equation that represents Maya's purchases is y = 7 -x. If y
represents the price of notebooks, and x represents the price of pencils, what are the prices of
the notebooks and pencils?
a) pencils: $4 notebook: $3 go to card 4
b) pencils: $6 notebook: $1 go to card 3
c) pencils: $3 notebook: $4 go to card 5
d) pencils: $1 notebook: $6 go to card 7
e) pencils: $4 notebook: $4 go to card 2
Step-by-step explanation:
We have y = 13 - 3x and y = 7 - x.
=> 13 - 3x = 7 - x
=> 2x = 6, x = 3.
Then y = 7 - (3), y = 4.
Hence the price of a pencil is $3 and the price of a notebook is $4. (C)
answer is c) pencils: $3 notebook: $4 go to card 5
i need help with math problem
Answer:
wow
Step-by-step explanation:
-6×-15=4×+35 i need help with this problem
Answer:
x = -5
Step-by-step explanation:
-6x - 15 = 4x + 35
+ 15 + 15
-6x = 4x + 50
-4x - 4x
-10x = 50
-10x/-10 = 50/-10
x = -5

8x + 5x what is it simplify
Answer:
13x
Step-by-step explanation:
you would just add the 2 numbers together and then keep the variable. if you know the variable (if there’s a sheet to go off of) then multiply and add but otherwise it’s just 8 + 5 then add an x. 13x
=====================================================
Explanation:
x is a placeholder for a number. Think of it like a box holding a number. Conveniently, the letter 'x' is in the word 'box', so its naturally fitting to use x here.
Writing 8x could represent the idea of us having 8 boxes that are identical. Adding on 5x means we add on 5 more boxes. This leads to 8+5 = 13 boxes in total.
This is one way to see how 8x+5x = 13x
Another way is to write it like this: 8x+5x = (8+5)x = (13)x = 13x. I used the distributive property here.
Combining these terms is possible because 8x and 5x are like terms. They have the same variable and same exponent. We're adding two of the same type of object together.

A jewelry store purchased a pair of earrings for $54
before a markup was applied.
There was a 90% markup. After the markup, a 6.5%
sales tax is added.
What is the total after markup and tax?
Answer:
$109.27
Step-by-step explanation:
100 + 90 = 190
54/100 X 190 = 102.60
100 + 6.5 = 106.5
102.60/100 X 106.5 = 109.269
monetary unit round to 2dp

on khan acad. if you click on the box, you can click on the pi icon to do it in terms of pi.
I always do in terms, but make sure to learn the other way :)
the formula for cone volume is π r^2 h/3
radius = 6
height = 8
π 6^2 8/3
π 36 8/3

What are the zeros of f(x)=(x+5)(x-9)?
Answer:
x= -5
x= 9
Step-by-step explanation:
Answer:
x = - 5, x = 9
Step-by-step explanation:
To find the zeros equate f(x) to zero, that is
(x + 5)(x - 9) = 0
Equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5
x - 9 = 0 ⇒ x = 9

Determine which function has a greater change of rate.
Be sure to show work as well.
Answer:
A
Step-by-step explanation:
You need to find the slope in A. y = x + (4x - 1) = 5x -1. The slope is 5.
In B, as x increases 1 unit, y increases 1 unit. Therefore, the rate of change is 1/1 = 1
Conclusion: In A the rate of change is 5 and in B the rate of change is 1.
Therefore, A has a greater rate of change

Explain in 1-2 sentences how you identify
proportional relationship
using a table or graph.
PLEASE helpppp
Answer:
You can tell because, as x increases/decreases, y increases/decreases at the same rate EACH TIME. This way, no matter how many times the proportions increase OR decrease, the ratio between x and y always stays the same.
