Answer:
1. -10
2.x=8
3. x= 2
Step-by-step explanation:
1. x = 3, 2x+x+2x+5
=2(-3)+(-3)+2(-3)+5
= -6 +(-3)+(-6)+5
= -6 -3 -6 +5 Next you have to use BODMAS rule so first addition
= -6 -3 -1
= -9-1
= -10
2. 2(2x+1)+x=x+2x+18
=4x+2+x=3x+18 then collect like terms:
=4x+x+2=3x+18
=5x+2=3x+18
=5x+2-2=3x+18-2
=5x=3x+16
=5x-3x=3x-3x+16
= 2x=16
2x/2=16/2
x=8
3.2x+x+2x=10+x
=6x=10+x
=6x-x=10+x-x
=5x=10
=5x/5=10/5
x=2

7x - 4 + = 12 show me the steps
Answer:
impossible, but two ways:
either:
x=16/7
or:
7x+8
Step-by-step explanation:
if it is 7x-4+12, then it is 7x+8 because it is an expression.
If it is 7x-4=12, then it is x=16/7 because it is an equation.
otherwise, it is python programming or impossible.

Answer:
18-Yes 19-No 20-yes 21- yes
Step-by-step explanation:
18
1 to 4, 5 to 20
Yes, this is correct
WE can multiply 1*5 and 4*5 to get 5 to 20
19
Wrong
3 to 11, 1 to 3 isn't correct
For example, if we were to divide 3 by 3 to get one, 11/3 is 2. (6)
So, no
20
2/3 is 2 to 3
14/21 is 14 to 21
If we multiply 2*7 and 3*7, we get 14 to 21
21 25 to 30 is equal to 35 to 42
They just added 7 to both numbers
if we divide ratio 1 by 5, we get 5:6
if we divide ratio 2 by 7 we get 5 to 6

Answer:
part 1:
see in the picture, E is the centre of the kite
1) AC = 2.EC = 40
2) CD = sqrt( ED² + EC² ) = sqrt(21² + 20²) = 29
3) ABE = 90⁰ - 51⁰ = 39⁰
4) BCE = BAE = 51⁰
part 2:
we have:
3x + 7 = (3x - 1 + 8x)/ 2
<=> 3x + 7 = 5.5x - 0.5
<=> 2.5x = 7.5
<=> x = 3
5) with x = 3 => UV = 3.3 - 1 = 9 - 1 = 8
6) XY = 3.3 + 7 = 9 + 7 = 16
7) TW = 8.3 = 24
9) the width of the base is x (x > 0)
we have:
28.5 = (x + 25)/2
<=> x + 25 = 57
<=> x = 32
5X +20 and the opposite of 20

what are the numbers from least to greatest -8 1/2, -4 1/2, -10 1/2, 4 1/2
Answer:
-10 1/2, -8 1/2, -4 1/2, 4 1/2
Step-by-step explanation:
Basically to get the answer, its easiest to convert the fraction to a decimal then put it on a number line. 1/2=0.5.
Answer:
-10 1/2, -8 1/2, -4 1/2, 4 1/2
Step-by-step explanation:
Something that helps is a number line, put 0 in the middle and put positive numbers on and negitive numbers so you can see what is smaller. For example:
least to greatest

The weight of sand and a large bag is 63.4 lb. The sand in the bag is divided equally into 20 small bags what is the weight in pounds of a list of the sand in each small bags
Answer: Weight of sand in each bag = 3.17 lb.
Step-by-step explanation:
Given : Total weight of sand = 63.4 lb
Total small bags = 20
Weight of sand in each small bag = (Total weight of sand ) ÷ (Total bags)
Weight of sand in each small bag = ( 63.4) ÷ (20)
Weight of sand in each small bag = 3.17 lb
Hence, the weight of sand in each small bag = 3.17 lb.
Answer:
3.17lb

tent: If a function f has an inverse and f(-3) = 6, then f-1(6)
The value of [tex]f^{-1}(6)[/tex] is [tex]-3[/tex].
Given:
The function [tex]f[/tex] has an inverse and [tex]f(-3)=6[/tex].
To find:
The value of [tex]f^{-1}(6)[/tex].
Explanation:
If a point [tex](a,b)[/tex] lies on the function [tex]f(x)[/tex], then the point [tex](b,a)[/tex] must lies on the inverse function [tex]f^{-1}(x)[/tex].
According to the given value [tex]f(-3)=6[/tex], the point [tex](-3,6)[/tex] lies on the function [tex]f(x)[/tex]. So, the point [tex](6,-3)[/tex] must be lies on [tex]f^{-1}(x)[/tex].
[tex]f^{-1}(6)=-3[/tex]
Therefore, the value of [tex]f^{-1}(6)[/tex] is [tex]-3[/tex].

Carin has 2/3 of a bottle of paint. She uses 1/6 of a bottle to paint one model airplane. How many model airplanes can carin paint with 2/3 of a bottle of paint. Answer
Answer:
4
Step-by-step explanation:
Given that :
Total fraction of paint Carin has = 2/3 bottle
Fraction used to paint a model airplane = 1/6
Number of model. Airplanes 2/3 of a bottle could paint ;
Total fraction of paint / fraction used to paint a model airplane
