Solve the system using elimination

Answer:

Step-by-step explanation:

10% of 50 = 5

5% of 50 = 2.5

to get to 65 u do 5+5 = 10 so so far that is 20% but 20% only gets u to 60 so u add another 10% to reach 65

u have used 30% so the answer to yr question is 30%

Answer:i think it is 5

Step-by-step explanation:

Answer:

x = -5 or 1/2

Step-by-step explanation:

From the question,

3x²+12x-7 = x²+3x-2

Collect like terms

3x²-x²+12x-3x-7+2 = 0

2x²+9x-5 = 0

Using factorization method to solve the quadratic equation

2x²+10x-x-5 = 0

(2x²+10x)-(x+5) = 0

2x(x+5)-1(x+5) = 0

(x+5)(2x-1) = 0

Either,

x+5 = 0

x = -5

or,

2x-1 = 0

2x = 1

x = 1/2.

Therefore,

x = -5 or 1/2

Answer:

the  percentage of the ramon earnings spent on electricity is 3.17%

Step-by-step explanation:

The computation of the percentage of the ramon earnings spent on electricity is shown below:

= Pays for electricity ÷ earnings per month

= $53 ÷ $1,670

= 3.17%

Hence, the  percentage of the ramon earnings spent on electricity is 3.17%

Answer:

answer 105

Step-by-step explanation:

3x5=15

than do 15x7 u will get 105

Answer and Explanation

This is because they are both the same opposite number, and you are adding.

But, if it was, [tex]\frac{64}{5}+\frac{64}{5}[/tex] then it would be [tex]25.6[/tex] or [tex]\frac{128}{5}[/tex].

So, the answer is 0.

The formula used to find the area of a triangle is

[tex] \frac{1}{2} b \times h[/tex]

so the area of the triangle is

[tex] \frac{1}{2} \times 8 \times 4[/tex]

because 8 is the base and 4 is the height of the triangle

Therefore the area of the triangle is 16

Answer:3 times 6 = 18 + (3 times 12)

Step-by-step explanation:

Answer: y = 800

Step-by-step explanation:

3(y+200) = 3000

y+200 = 1000 (dividing 3 from both sides)

y = 800

Answer:

x ≤ 2

(when graphed, closed circle on two, shaded to the left)

Step-by-step explanation:

3/4 x - 2/3 ≤ 5/6

Add 2/3 to both sides:

3/4x ≤ 5/6 + 2/3

3/4x ≤ 3/2

Divide by 3/4 on both sides:

x ≤ 3/2 ÷ 3/4

x ≤ 2

The scatter graph for level of water in a dam on each day and date for one month type of data is most likely to suggest a linear association.

A scatter plot, like a scatter chart or graph, employs dots to represent the values of two numerical variables. The horizontal value represents the data from individual points. Hence, it is used to observe the relationships between variables.

The scatter plot can provide the values for the data set. The points can be of various sizes, colours, and forms. The information is presented in the form of points.

The values are represented on the vertical axis. The data association can be positive, negative, or neutral. A mosaic and a fluctuational diagram can be displayed on the scatter plot.

Thus, the plot which can be linear association form level of water in a dam on each day and date for one month

Answer:

The center of the circle is [tex]C(x,y) = (2, 3)[/tex].

Step-by-step explanation:

The center of the circle is the midpoint of the segment between the endpoints. We can determine the location of the center by this vectorial expression:

[tex]C(x,y) = \frac{1}{2}\cdot R_{1}(x,y)+ \frac{1}{2}\cdot R_{2}(x,y)[/tex] (1)

Where:

[tex]C(x,y)[/tex] - Center.

[tex]R_{1} (x,y)[/tex], [tex]R_{2} (x,y)[/tex] - Location of the endpoints.

If we know that [tex]R_{1} (x,y) = (-2,10)[/tex] and [tex]R_{2} (x,y) = (6,-4)[/tex], then the location of the center of the circle is:

[tex]C(x,y) = \frac{1}{2}\cdot (-2,10)+\frac{1}{2}\cdot (6,-4)[/tex]

[tex]C(x,y) = (-1, 5) + (3, -2)[/tex]

[tex]C(x,y) = (2, 3)[/tex]

The center of the circle is [tex]C(x,y) = (2, 3)[/tex].
