Answer:
The value of x = 20.
Step-by-step explanation:
Figure B is the scale image of A.
It is clear that:
side 10 of figure A has the image side of 12.5 in figure B.which can be obtained by multiplying 10 with 1.25
i.e.
10*1.25=12.5so the side 16 of figure A must have to be multiplied by 1.25 to get the image the figure B.
so
16*1.25=20Therefore, the value of x = 20.

Answer: I just took the test and the answer is Student should show that the solution to the system of equations 7x - y = 4 and 2x - 3y = 1 is the same as the solution to the given system of equations.
Step-by-step explanation:
The solution for the given system of linear equations is (32/69, -10/23).
The given system of equations are 3x-6y=4 and 6x+11y=-2.
What is a linear system of equations?A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.
Here,
3x-6y=4 ---------(I) and 6x+11y=-2 ---------(II)
Multiply equation (I) by 2, we get
6x-12y=8 ---------(III)
Subtract equation (III) from (II), we get
6x+11y-(6x-12y)=-2-8
⇒ 23y=-10
⇒ y=-10/23
Substitute y=-10/23 in (I), we get
3x-6(-10/23)=4
⇒ 3x+60/23=4
⇒ 3x=4-60/23
⇒ x=32/69
So, solution is (32/69, -10/23)
Therefore, the solution for the given system of linear equations is (32/69, -10/23).

Hope I helped
Answer:
1 1/2
Step-by-step explanation:
To add fractions together you have to have a common denominator. To do this, I multiplied -1/5 by 2 to get -2/10 which has the same denominator (10) as 17/10. now you add the numerator of both fractions. -2+17 equals 15. so your new fraction is 15/10. 15 divided by 10 is 1.5 which you can write as 1 and 1/2.

322 rounded to the greatest place value
Answers
Answer:
322 rounded to the greatest place value
320After rounding off 322 to the nearest tenths, the resultant number is 320.
What is rounding off?When a number is rounded off, its value is maintained but is brought closer to the next number, simplifying the number. For entire numbers as well as decimals at different places of hundreds, tens, tenths, etc., it is done. Round the number up if 5, 6, 7, 8, or 9 follow the number you are rounding.For instance, 40 when rounded to the nearest ten is 38.
So, 322 rounded to tenth place:
Since in the tenth place, there are 2.Then after rounding off:
322 ⇒ 320Therefore, after rounding off 322 to the nearest tenths, the resultant number is 320.
