Answer:
Ok
Step-by-step explanation:
-2/7 * 5/6 = - 10 / 42
-2/7 * - 1/3 = 2/21
So the equation now :
-10 / 42 + 2/1 + 2/21 =
Let the have same denominator
- 10 / 42 + 84 / 42 + 4/ 42 =
= 78 / 42
Solve this system of equations
X=y+2
2y-3x=15
Answer:
x=-19, y=-21
Step-by-step explanation:
[tex]\begin{bmatrix}x=y+2\\ 2y-3x=15\end{bmatrix}[/tex]
[tex]\mathrm{Substitute\:}x=y+2[/tex]
[tex]\begin{bmatrix}2y-3\left(y+2\right)=15\end{bmatrix}[/tex]
Simplify
[tex]\begin{bmatrix}-y-6=15\end{bmatrix}[/tex]
Isolate y for -y - 6 = 15: y = -21
[tex]\mathrm{For\:}x=y+2[/tex]
[tex]\mathrm{Substitute\:}y=-21[/tex]
[tex]x=-21+2[/tex]
Simplify
x=-19
[tex]\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}[/tex]
[tex]x=-19,\:y=-21[/tex]
y=-21,x=-19
you can only solve this using simultaneouse solution. first, make x the subject in the second equation.2y-3x=15
In doing so x=-5+2/3y. You the multiply both equationby the co-efficient of x then you subtract the equations giving 1/3y=-7. hence y=-21.you then substitute the value for y into equation 1 where x=y+2 giving x=-19.

19) Find the ratio between number faces and number of edges in the below rectangular prism.
Answer:
1 : 2
Step-by-step explanation:
Rectangular prism
Faces = 6
Up and bottom ; right and left ; front and back . So total 6 faces.
Edges: Two faces meet at an edge.
Edges = 12
Face :Edges = 6 : 12
= 6÷6 : 12÷6
= 1 : 2
Find the equation of the line shown
Answer:
y = 2x
PRIMARY METHOD
Identify two points, find their slope, and write an equation
(1, 2) and (3, 6)
m = (y₂ - y₁)/(x₂ - x₁)
m = (6 - 2)/(3 - 1) = 4/2
m = 2
(1, 2)
y - y₁ = m (x - x₁)
y - 2 = 2 (x - 1)
y = 2x - 2 + 2
y = 2x
SIMPLER METHOD
Rise/Run
(0,0) to (1, 2) = 2/1 = 2
(1, 2) to (3, 6) = 4/2 = 2
Answer:
y = 2x
Step-by-step explanation:
The graph shows a straight line that passes trhough the origin, so it is a direct proportion relation with equation of the form y = mx.
To find the slope, use any easy-to-read point, and divide the y-coordinate by the x-coordinate. For example, use (1, 2).
m = 2/1 = 2
y = 2x
A graph is shown. Which of the following equations are represented by the graph?
Answer:
Equations II and IV
Step-by-step explanation:
See attached image.
Find the equation of the line in the form of y=mx+b, where m is the slope and b the y-intercept. Pick any two points to calculate the Rise/Run, or slope, of the line, as shown. The y-intercept, b, is the value of y when x=0. Rearrange the resulting equation, as necessary, to see if it matches any of the options. In option IV, I rearranged the answer, as it was easier to get it into the desired form of y=mx+b.
As shown, equations II and IV both match.
Lindy works at a pizza restaurant and gets a 10% employee discount. She knows that if she orders d drinks and a medium pizza with t toppings, her total cost can be found using this expression:

B.
$28.40
C.
$17.28
D.
$16.52
Answer:
Option A. $17.28
Step-by-step explanation:
we have the expression for the cost
In this problem we havesubstitute the given values in the expression to obtain the cost
please get this right !!!
Answer:
3rd option
Step-by-step explanation:
probability (P) is calculated as
P = [tex]\frac{desired outcome}{total outcomes}[/tex]
deired outcome is red marble = 4
total outcomes = 4 + 2 + 3 = 9
then
P(red) = [tex]\frac{4}{9}[/tex]
since the marble is not replaced then total outcomes = 8
desired outcome is yellow marble = 2
P(blue) = [tex]\frac{2}{8}[/tex] = [tex]\frac{1}{4}[/tex]
then
P(red and yellow ) = [tex]\frac{4}{9}[/tex] × [tex]\frac{1}{4}[/tex] = [tex]\frac{1}{9}[/tex]

SOMEONE PLS HELP !!!!!!!
Answer:
5/2
Step-by-step explanation:
4(x + 7) = 38
x + 7 = 38/4
x = 38/4 - 7
x = 38/4 - 28/4
x = 10/4
x = 5/2
Reasoning:
1. Divide both sides by 4
2. Isolate variable by subtracting 7 on both sides
3. Convert 7 into an improper fraction to subtract constants
4. Simplify

Answer:
Both
Claire
Andre
Neither
Step-by-step explanation:
We have to determine whether each point lies on Claire's line (blue) and whether it lies on Andre's line (black).
Point A is the intersection of both lines, hence the statement represents them both.
Point B only lies on Claire's line.
Point C is the start of Andre's line.
Point D is outside of both lines.

Ms. Gallegos burns 236 calories while riding her bike each hour. She wants to burn more than 590 calories riding her bike at the same rate.
Which inequality represents all possible values for t, the number of hours Ms. Gallegos must ride her bike to burn more than 590 calories?
Answer:
T > 2.5
Explaination -
t > 2.5
t < 2.5
t > 0.4
t < 0.4
Here it is given that Gallegos burns 236 calories riding her bike each hour.
She wants to burn more than 590 calories riding her bike at the same rate.
Let the time required = t hours
So
236t > 590
⇒ t > 590/236
⇒ t > 2.5
Therefore, the answer is t > 2.5

Answer:
[tex]\sqrt{29}[/tex]
Step-by-step explanation:
Use the distance formula!
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
If we plug in the coordinates:
[tex]d=\sqrt{(3-(-2))^2+(4-2)^2} \\d=\sqrt{25+4}\\ d=\sqrt{29}[/tex]
That's our answer!

Mia buys 404.6 square feet of new wood
flooring. How much did she pay for the wood if it cost $0.99 Per square foot?
Answer:
$400.55 (to the nearest cent)
Step-by-step explanation:
she paid
= 404.6 x 0.99
= 400.554
= $400.55 (to the nearest cent)
hope this helps!
Answer:
$ 400.554
Step-by-step explanation:
Let the unknown price be x.
1 ft² ⇒ $ 0.99
404.6 ft² ⇒ x
Let us use cross multiplication to find the value of x.
0.99 × 404.6 = 1 × x
400.554 = x
Therfore, she'll pay $ 400.554 for 404.6 ft²
