The simplified version of this x-2z
Step-by-step explanation:
You need to start by combining like terms. You can start with the terms that have the variable x in them. By combining those terms, the equation becomes x+3y-z-3y-z.
From here, you can combine the terms 3y and -3y, which bring the equation to x-z-z.
From here, combine the terms with the variable z. This would bring the equation down too x-2z, your final answer.
I need 110g of flour to make something. A 10kg (22lb) bag of four is $12. How much does that 110g cost?
Answer:
Cost of 110 g bag = $ 0.132
Step-by-step explanation:
As we know ,
1 kg = 1000 g
⇒1000 g = 1 kg
⇒1 g = [tex]\frac{1}{1000} = 0.001[/tex] kg
⇒110 g = 110 (0.001) kg = 0.11 kg
⇒110 g = 0.11 kg
Now,
Cost of 10 kg bag = $12
⇒Cost of 1 kg bag = [tex]\frac{12}{10} = 1.2[/tex]
⇒Cost of 1 kg bag = $ 1.2
⇒Cost of 0.11 kg bag = $ (0.11)(1.2) = $ 0.132
∴ we get
Cost of 110 g bag = $ 0.132

10. 156.25/6.25= 25 hrs
Answer:
9. x = 7, y = 10
Step-by-step explanation:
9. I first set up an equation x+y=17
then I set up a second equation y = x+3
I substitute y for x+3 and get x+x+3=17 or 2x+3=17
then I just evaluate the equation x=7
I then use my first equation x+y = 17 and substitute the value 7+y= 17 and get y = 10
10. Just divide 156.25 with 6.25 to get the number of hours she had to work to get 156.25 dollars. The answer would be 156.25/ 6.25 = 25

Answer:
Part A: B
Part B: 1
Step-by-step explanation:
Part A:
The meaning of "at most" is "less than or equal to." If we assume that the variables x and y represent numbers of loaves of banana bread and nut bread, respectively, then the first problem statement tells you ...
x + y ≤ 30 . . . . . the total of loaves baked is at most 30
Only one answer choice has this inequality listed: choice B.
__
Part B:
The numbers of loaves of bread will not be negative. The only quadrant that has both coordinates positive is the 1st quadrant.
__
Comment on quadrant
Real-world problems involving numbers of items are often expressed in terms similar to those seen here. The assumption that is made in all such problems is that the quantity of items cannot be negative. That is, the constraints x ≥ 0 and y ≥ 0 are always considered part of the problem description. These limit solutions to Quadrant 1. (or I, if you use Roman numerals for numbering quadrants)

Four basketballs and six baseballs cost $44. Five basketballs and four baseballs costs $48. Determine the cost for one basketball and one baseball.
Answer:cost for basket ball= $8 and
cost of baseball = $2
Step-by-step explanation:
Step 1
Let the cost of basket ball be represented as x
and cost of baseball = y such that
Four basketballs and six baseballs cost $44 will be expressed as
4x+ 6y= 44 --- eqn 1 also
Five basketballs and four baseballs costs $48 will be expressed as
5x+ 4y= 48--- eqn 2
Step 2
Having obtained two expressions we can now sole
4x+ 6y= 44 --- eqn 1
5x+ 4y= 48--- eqn 2
multiplying eqn 1 by 5 and eqn 2 by 4
20x+ 30y =220---- eqn 3
20x+ 16y=192-----eqn 4
subtracting equation 4 from 3 we now have
14y=28
y= 28/14
y=2 = $2
from equation 1
4x+ 6y= 44, putting the value of y=7 to find x
4x+ 6(2)= 44
4x+12= 44
4x= 44-12
4x=32
x= 32/4
x=8=$8
cost for basket ball= $8 and
cost of baseball = $2

Which pair of angles is an example of supplementary angles?
Answer:
A. Angle 1 and Angle 7
Step-by-step explanation:
Those two are the only angles that when added up, the sum is 180.
Angle 7 and Angle 2 are also congruent, so if Angle two forms a straight line with Angle 1, Angle 7 should be able to do that too.

HELP ASAP DUE TONIGHT! (slopes) (brainliest)
Answer:
(0,35)
(1,50)
(2,65)
(3,80)
Y intercept: 35
Slope: 15
This means that it has an independent cost of $35 and a variable fee of 15
Step-by-step explanation:
It's near impossible for me to show you where the line goes and so I'm just going to give you five or so points
To get the 5 point just plug different x values in
(0,35)
(1,50)
(2,65)
(3,80)
The slope intercept equation looks like the following
y=mx+b
where b is the y intercept and m is the slope
this means our equation's slope is 15 and the y intecept
is 35

A= [tex]\pi (6^2 )[/tex]
6*6 =36
multiply 3.14 by 36
36*3.14=113.04

Answer:
Z=20 Degrees
Step-by-step explanation:
We know that all of the angles of a triangle add up to 180, so:
65+55+ Angle A = 180
Simplify:
120+ Angle A = 180
Subtract 120 from both sides:
Angle A = 60
If you look at the bottom you can see that the 15 turns into 5, meaning it is being divided by 3, so:
60/3=20
Z=20 Degrees
Answer:
Angle E is 60 degrees
Step-by-step explanation:
So z is an angle.
That would be point E.
This triangle was dilatated so we can match it up with the larger one. In a dilation, angle measures do not change. So matching up the points E would be equal to A, which of course it the only one with an angle measure not given.
All you have to do is add up the two angle measures and subtract that by 180 (total of all angles combined).
So 65+55=120
180-120=60
Angle A is 60
Which makes angle E 60 as well
Hope that helps!

The normal price of a bicycle is £120
In a sale, there is 1/5 off the normal price of the bicycle.
Work out the price of the bicycle sale?
Answer:
76
Step-by-step explanation:
100% = 120
1/5 of 100% = 20%
20% = 120÷100×20
= 24
100-24= 76
Does a shape with a right angle always have perpendicular sides? Explain
Answer:
Yes
Step-by-step explanation:
A right angle means that the lines will create an L or X or T when they intersect. This is exactly the definition of perpendicular, that the shapes will intersect and create at least one right angle.
Answer:
If you ever see a little square at the corner of a shape, then you know that not only is this a right angle, and thus, 90 degrees, but that the two lines that form such an angle are perpendicular to one another. Squares and rectangles always have four right angles!
