-x + y = 5
x - 5y = 2 ---> x= 5y + 2
I have solved the second equation for x. What is the next step if solving this system with substitution?
A. -(5y+2) + y = 5

B. -x + y = 5 + 5y + 2

C. None of the Above

D. -x + 5y + 2 = 5

Answer:

Step-by-step explanation:

I sympathize. The question is not very clear: you don't know what A and B really are (I mean which vertex).

However it is a rhombus, and you are to assume that B follows A. So put A anywhere and make B follow it. They are supplementary which means they add to 180 degrees. All rhombi have that property.

A + B = 180

A/B = 2/1

Cross Multiply the second equation

A = 2*B

Put 2B into the first equation.

2B + B = 180         Combine the left terms

3B = 180                Divide both sides of the equation by 3

B = 180 / 3

B = 60

B = 60

A = 180 - 60 = 120

Label the two acute angles as 60 and the two obtuse angles as 120.

Acute: means less than 90

Obtuse: means more than 90

Answer:

y=3x and y=x+4

that is the third option

Step-by-step explanation:

let the larger number be y and the smaller one be x

From the mathematical statements,

y=3x

Also

y=x+4

Step-by-step explanation:

Line parallel to the line y = -2/3 x + 8 also has the slope -2/3.

Since the line passes through (4, -5), we have (x - 4) written on the right side and (y + 5) on the left side.

Hence the equation is y + 5 = -2/3 * (x - 4). (B)

Answer: Well there's a geometry definition stating that the two angles are equal.

But ig i can try to make a proof.

First make a perpendicular bisector from the vertex to the bottom splitting the bottom side in half.

Now because of LL theorem, and the reflexive property, the two triangles are equal.

Now using cpctc, the two angles are also equal.

Answer:

x=14

Step-by-step explanation:

11x+18=172, subtract 17 from both sides, 11x=154, divide 11 from both sides, x=14

Answer:

800 children’s ticket were sold and 400 adult tickets were sold

Step-by-step explanation: using elimination

variables-

amount of children’s ticket sold: C

amount of adult tickets sold: A

equations-

A+C=1200

5A+11C=10,800

solving-

(A+C=1200) -5 —> -5A-5C=-6000

5A+11C= 10,800

use elimination on those two equation and you get C=800, A=400.

to check you plug in the numbers into one of the equations, doesn’t matter which one.

Answer:

The x=8 is only for the x interecept, and the x-intercept is (8,0). You assume y to be 0 then you say it's 2, that is incorrect. x and y interecepts should not be combined. The correct x-intercept and y-intercept are (8,0) and (0,2) respectively

Answer:

A 33 degrees

Step-by-step explanation:

[tex]x \degree = 180 \degree - (23 \degree + 124 \degree) \\ \\ x \degree = 180 \degree - 147 \degree\\ \\ x \degree = 33 \degree \\ \\ x = 33[/tex]

Answer:

A) 33

Step-by-step explanation:

the angles of a triangle always add up to 180.

124 + 23 + x = 180

combine like terms

147 + x = 180

147 + x - 147 = 180 - 147

x = 180 - 147

x = 33

Answer:

$1,173,226,826  

Step-by-step explanation:

The estimate of the increase in dollars earnings is the difference between this year's earnings and last year's earnings. In other words, the increase in earnings is the excess of current year's earnings over last year's earnings as computed below:

increase in earnings=this year's earnings-last year's earnings

this year's earnings=$3,632,859,678

last year's earnings=$2,459,632,852

increase in earnings=$3,632,859,678-$2,459,632,852

increase in earnings=$ 1,173,226,826  

Answer:

√38 , √44

Step-by-step explanation:

Answer:

10 hours

$43

Step-by-step explanation:

Given that:

Jonny:

Shoe rental = $13

Fee per hour = $3

Dustin :

Shoe rental = $3

Fee per hour = $4

Number of hours bowled is the same

Let number of hours bowled = x

$13 + 3x = $3 + 4x

3x - 4x = $3 - $13

-x = - 10

x = 10

Number of hours each bowled = 10

Amount spent :

Jonny:

$13 + 3x = $13 + $3(10) = $13 + $30 = $43

Dustin :

$3 + 4x = $3 + $4(10) = $3 + $40 = $43
