<4 and <8 are corresponding angles. They are in the same position.

They have equal measure.

<8= 113 degrees.

I hope this helps!

0.6(4-2x)=20.5-(3x+10)

solong [7]

The solution of 0.6(4-2x)=20.5-(3x+10) is x = 4.5

Solution:

Given, expression is 0.6 ( 4 – 2x ) = 20.5 – ( 3x + 10 )

We have to solve the above given equation for x.

Now, take the equation

$\rightarrow 0.6(4-2 x)=20.5-(3 x+10)$

We have to use BODMAS rule. BODMAS means sequence of operations which is brackets, order, division, multiplication, addition and then subtraction

On solving the brackets, we get

$\rightarrow 0.6 \times 4-0.6 \times 2 x=20.5-3 x-10$

Now multiplication is given preference

$\rightarrow 2.4-1.2 x=10.5-3 x$

$\rightarrow 3 x-1.2 x=10.5-2.4$

Now subtraction is done

$\rightarrow 1.8 \mathrm{x}=8.1$

Now division is performed

$\rightarrow x=\frac{8.1}{1.8}=4.5$

Hence, the value of x is 4.5

Systems of linear equations question 7 which system of equation has no solution

makvit [3.9K]

Answer:

The bottom left system of equations has no solutions.

Step-by-step explanation:

A solution to the system of equations is a point where the graphs of equations intersect, because the intersection point represents a point that is common to both equations; Therefore, a system that has no solutions, will have graphs that will never intersect.

Now, looking at the 4 graphs given, we see that the upper-left graph represents lines which intersect; therefore, this system has a solution.

The upper-right graph represents only one equation and not a system—it could well be that the red line hides another line that is exactly beneath it, in which case the system would have infinitely many solutions.

The bottom-left graph represents lines that are parallel—they are never going to meet; therefore, this system has no solutions.

The bottom-right graph represents lines that have a point of intersect, and therefore, have a solution.

Thus only the bottom-right graph has no solutions.

A system of equations and its solution are given below.

ratelena [41]

Answer:

Step-by-step explanation:

The second equation in system B is only in terms of y, so we need to use elimination to eliminate the x term from the second equation in system A.

To do that, we need to multiply the first equation by 5.

5 (-x − 2y = 7)

-5x − 10y = 35

Add to the second equation. Notice the x terms cancel out.

(-5x − 10y) + (5x − 6y) = 35 + (-3)

-16y = 32

Combining this new equation with the first equation from system A will get us system B.

-x − 2y = 7

-16y = 32

Given the proportion x/y = 2/5, what ratio completes the equivalent proportion: x/2= ?/?

prohojiy [21]

Cross multiply the original proportion

5x = 2y Divide by 2
5x/2 = y Now divide by 5
x/2 = y/ 5

So the answer is y/5
