Answer:
Step-by-step explanation:
Simplifying
7x + -2y = 1
Solving
7x + -2y = 1
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2y' to each side of the equation.
7x + -2y + 2y = 1 + 2y
Combine like terms: -2y + 2y = 0
7x + 0 = 1 + 2y
7x = 1 + 2y
Divide each side by '7'.
x = 0.1428571429 + 0.2857142857y
Simplifying
x = 0.1428571429 + 0.2857142857y
///////////////////////
Simplifying
2y = x + -1
Reorder the terms:
2y = -1 + x
Solving
2y = -1 + x
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Divide each side by '2'.
y = -0.5 + 0.5x
Simplifying
y = -0.5 + 0.5x
Answer:
1) y = − 1 2 + 7 x 2
2) x = 2 y + 1
Step-by-step explanation:
Subtract 7 x from both sides of the equation. − 2 y = 1 − 7 x Divide each term by − 2 and simplify.
y = − 1 2 + 7 x 2
Solve for x by simplifying both sides of the equation, then isolating the variable. x = 2 y + 1

The diagram shows two right-angled triangles. OAB
and OCD
Work out the length of BD. I
7 cm
4 cm
14 cm
Given:
The diagram shows two right-angled triangles OAB and OCD.
To find:
The length of BD.
Solution:
Let the length of BD is x.
In triangle OAB and OCD,
[tex]\angle AOB\cong \angle COD[/tex] (Common angle)
[tex]\angle ABO\cong \angle CDO[/tex] (Right angle)
[tex]\Delta OAB\sim OCD[/tex] (By AA property of similarity)
We know that, the corresponding sides of similar triangles are proportional. So,
[tex]\dfrac{AB}{CD}=\dfrac{OB}{OD}[/tex]
[tex]\dfrac{4}{7}=\dfrac{14}{14+x}[/tex]
[tex]4(14+x)=14(7)[/tex]
[tex]56+4x=98[/tex]
Subtracting 56 from both sides, we get
[tex]4x=98-56[/tex]
[tex]4x=42[/tex]
[tex]x=\dfrac{42}{4}[/tex]
[tex]x=10.5[/tex]
Therefore, the length of BD is 10.5 cm.

Jane and her neighbor Amil are jealous of each other’s gardens. Amil’s garden is twice the size of Jane’s garden. Janes garden has 22 watermelons and Amil’s garden has 28. Whose garden has the greatest density of watermelons Support your answer with math?
Answer:
Jane has the greatest desity of watermelons.
Step-by-step explanation:
25ft2/22= 1.13 100ft2/28= 3.57
For example, if Jane’s garden is 25 square feet then that means there would be about 1 watermelon per square foot. If Amil’s garden is twice the size of Jane’s at 100 square feet, then you could fit about 3 watermelons per square foot. This means that Jane has the greatest density of watermelons because Amil can fit more watermelons per square foot.

rearrange the following linear equation into y=mx+b form and identify the slope and the y intercept 2y=2x+6
Answer:
Step-by-step explanation:
we need the equation to be like y=mx+b so we have to simplify our equation
2y=2x+6
divide everything by 2
so it’s y=x+3 and that’s ur answer

Given:
A figure in which a transversal line t intersect the two parallel lines a and b.
To find:
The measure of the numbered angles.
Solution:
If a transversal line intersect the two parallel lines, then
1. Corresponding angles are equal.
2. Alternate interior angles are equal.
3. Alternate exterior angles are equal.
Now,
[tex]m\angle 1+99^\circ=180^\circ[/tex] (Linear pair)
[tex]m\angle 1=180^\circ-99^\circ[/tex]
[tex]m\angle 1=81^\circ[/tex]
[tex]m\angle 2=99^\circ[/tex] (Vertically opposite angles)
[tex]m\angle 3=\angle 1=81^\circ[/tex] (Vertically opposite angles)
[tex]m\angle 4=99^\circ[/tex] (Corresponding angles)
[tex]m\angle 5=\angle 3=81^\circ[/tex] (Alternate interior angles)
[tex]m\angle 6=99^\circ[/tex] (Alternate exterior angles)
[tex]m\angle 7=\angle 3=81^\circ[/tex] (Corresponding angles)
Therefore, [tex]\angle 1=81^\circ, \angle 2=99^\circ,\angle 3=81^\circ, \angle 4=99^\circ,\angle 5=81^\circ, \angle 6=99^\circ,\angle 7=81^\circ[/tex].

Marie can make \frac{1}{8} 8 1 quart of orange juice in \frac{3}{4} 4 3 of a minute by squeezing oranges. At this rate, how much juice can she make in 1 minute?
Answer:
[tex]\frac{1}{6}\ juice[/tex]
Step-by-step explanation:
The computation is shown below:
Since [tex]\frac{1}{8}[/tex] quart of juice would be make in [tex]\frac{3}{4}[/tex] minutes
So for one minute, the juice would be make
[tex]\frac{4}{3}\times \frac{3}{4} \ minute= \frac{4}{3} \times \frac{1}{8} \ juice\\\\1\ minute= \frac{1}{6}\ juice[/tex]
hence, the same would be considered and relevant too

use the graph above. find the slope and the y-int, then give the equation of the line y=mx+b
Answer: y = 2x + 4
Step-by-step explanation:
By looking at the graph, we can use rise over run to figure out the slope:
[tex]\frac{rise}{run} = \frac{2}{1} = 2[/tex]
Next, to find the y-intercept, see the point where the line meets with the y-axis, which is at (0,4). Now, simply place those variables found into y=mx+b, where m is the slop and b is the y-intercept.
y = mx + b
y = 2x + 4
Si mi mamá compra un refrigerador del costo de $11,780 y con el descuento del 25% cuanto pagara en total mi mamá
Answer:
Precio a pagar= $8,835
Step-by-step explanation:
Costo de lista del refigerador= $11,780
Porcentaje de descuento= 25% = 0.25
Para calcular el precio que va a pagar con el descuento aplicado, tenemos que usar la siguiente formula:
Precio a pagar= costo de lista*(1- porcentaje de descuento)
Precio a pagar= 11,780*(1 - 0.25)
Precio a pagar= 11,780*0.75
Precio a pagar= $8,835
