Answer:
1. X= 1/3 z -1
2. X= 1/3z + -2/3
Step-by-step explanation:
z=3x+3
Step 1: Flip the equation.
3x+3=z
Step 2: Add -3 to both sides.
3x+3+−3=z+−3
3x=z−3
Step 3: Divide both sides by 3.
3x/3 = z-3/3
Step 1: Flip the equation.
3r+2=z
Step 2: Add -2 to both sides.
3r+2+−2=z+−2
3r=z−2
Step 3: Divide both sides by 3.
3r/ 3 = z-2/3
Andrea’s income from a lemonade stand was $28. Supply expenses were $9. Write and then evaluate an expression to find Andrea’s profit or loss. Expression:___
Andrea’s profit or loss is____dollars.
Answer:
9-28= 21

She made profit because she lost 9 dollars, and then gained 28$ back, which would then equal to $21, so Andrea made a profit of $21.
Breannas cat weighs 3200 grams. Her neighbors cat weighs 4.68 kilograms. What is the difference, in grams, of the weights of two cats
Answer:
1480 grams.
Step-by-step explanation:
3200 grams = 3200/1000
= 3.2 kgs.
Difference in weight = 4.68 - 3.20
= 1.48 kgs
= 1480 grams.
Answer:
3,200g - 4.68kg = 1480
Step-by-step explanation:
4.68k g = 4,680 g
1 kg = 1,000 g
4,680 - 3,200 = 1480

Felix used place value and the distributive property to rewrite the expression 9(278). His work is shown below. 9(278) = 9(200 + 70 + 8) What should Felix do to find the product? Select all that apply. Multiply 9(200) and multiply 70(8). Multiply 9(200), 9(70), and 9(8). Multiply 9(200) and then add (70 + 8). Distribute the 9 to each addend. Find the sum of (1,800 + 630 + 72).
Step-by-step explanation:
Distributive property is as follows :
a(b+c) = ab + ac
Felix used place value and the distributive property to rewrite the expression 9(278).
Place value of 278 = 200 + 70 +8
He has done like : 9(278) = 9(200 + 70 + 8). Now, the steps are as follows :
9(278) = 9(200 + 70 + 8)
= 9(200)+9(70)+9(8)
= 1800 + 630 +72
= 2502
Hence, option (d) "Distribute the 9 to each addend. Find the sum of (1,800 + 630 + 72)" should be the correct answer.

Find the distance from (-3,-1) to (2, 11).
Answer:
13
Step-by-step explanation:
Use the distance formula to find the distance between points
[tex] (x_1, y_1) [/tex] and [tex] (x_2, y_2) [/tex].
Distance formula:
[tex] distance = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
We have [tex] x_1 = -3, y_1 = -1, x_2 = 2, y_2 = 11 [/tex].
[tex] distance = \sqrt{(2 - (-3))^2 + (11 - (-1))^2} [/tex]
[tex] distance = \sqrt{(2 + 3)^2 + (11 + 1)^2} [/tex]
[tex] distance = \sqrt{5^2 + 12^2} [/tex]
[tex] distance = \sqrt{25 + 144} [/tex]
[tex] distance = \sqrt{169} [/tex]
[tex] distance = 13 [/tex]
Which line is parallel to the line shown on
the graph?
A. 4x + 5y = -10
B. 4x - 5y = 0

C
Step-by-step explanation:
I’m pretty sure
The line whose slope will be same as that of the graph given, will be the line parallel to the given line.
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
Given is a graph of a line.
For a given line to be parallel to the given line, its slope should be same as that of the line plotted. Since the graph is not given, we can make an estimate for the equation of the line parallel to the given line. The four equations given will have their slopes as mentioned -
[A] - 4x + 5y = - 10 [m] = -4/5
[B] - 4x - 5y = 0 [m] = 4/5
[C] - 5x + 4y = 24 [m] = -5/4
[D] - 5x - 4y = -8 [m] = 5/4
Now, the line whose slope will be same as that of the graph given, will be the line parallel to the given line.
Therefore, the line whose slope will be same as that of the graph given, will be the line parallel to the given line.

the sum of three consecutive even integers is 30 more than the smallest integer. Find the largest integer.
Answer:
10 1/4
Step-by-step explanation:
Assume x as the smallest integer.
Since it is consecutive, you have to add 1 in order to get the next integer.
Equation:
x+x+1+x+2=x+30
x=8 1/4
You need to add 2 to get the largest integer.
So, 8 1/4 + 2 = 10 1/4

9x+7 when x+3
and
x4 when x =3
pls do step by step
Answer:
34
Step-by-step explanation:
9x+7 when x=3
Plug 3 into the equation for the variable x
So, it would be 9(3)+7
Multiply 9×3 together to get 27
Finally, add 27 and 7 together
The answer should be 34
Answer:
x=1
Step-by-step explanation: 9x+7=16
Subtract 7 from both sides.
9x=16−7
Subtract 7 from 16 to get 9.
9x=9
Divide both sides by 9.
Divide 9 by 9 to get 1.
x=1

what is the equation of the line that passes through the points (11, - 4) and (13,- 7) in slope-intercept form?
answer choices shown in picture
Answer:
E. None of these
Step-by-step explanation:
Points: (11, -4), (13, -7)
slope = m = (y2 - y1)/(x2 - x1) = (-7 - (-4))/(13 - 11) = (-7 + 4)/2 = -3/2
y - y1 = m(x - x1)
y - (-4) = (-3/2)(x - 11)
y + 4 = (-3/2)x + 33/2
y + 8/2 = (-3/2)x + 33/2
y = (-3/2)x + 25/2
Answer: E. None of these
Step-by-step explanation:
A(11,-4) B(13,-7)
x1 y1 x2 y2
y=mx+c
-4=11m+c -(i) -7=13m+c -(ii)
Subtract equation (ii) from (i)
-7=13m+c
-4=11m+c
+ - -
-3=2m
2m=-3
m=-3/2
put m=-3/2 in equation (ii)
-7=13*(-3/2)+c
c=-7+39/2
c=(-14+39)/2
c=15/2
y=mx+c
y=-3/2x+15/2
y=(-3x+15)/2
2y=-3x+15
2y+3x-15=0
