Answer:
Step-by-step explanation:
4x − 1 = 19
solving for x, x = 5
2x − 4 = 10
x=7
2x + 2y = 48
x=24-7
y=24-x
5x + 2y = 90
x=18-2y/5
y=45-5x/2
all the situations I could find hope this helps for each equation.
Find the x-intercept of a line that has the following equation: 2y=3x−6
Answer:
2
Step-by-step explanation:
To find the x-intercept of the equation we have to substitute y = 0 in it.
=> 0 = 3x - 6
=> 3x = 6
=> x = 2
Therefore the line will meet x-axis at (2,0) which means it'll have x - intercept of 2 units.
83 square root to the nearest tenth

Answer:
EH = 16
Perimeter = 46
Step-by-step explanation:
We see that the ratio between the big shape and small shape is 3:2. 3x=24, so x=8. EH=2x=16.
For the second problem, the perimeter is 46.
This is because it also follows the same rule as 3:2. If you do this for every side, you find out that the sides are 10, 10, 6, 12, and 8. Add them together to get 46.
I hope this helped!

Rotate RST 90 degrees counterclockwise around the origin
Step-by-step explanation:
Unfortunately, you haven't given the coordinates of RST so I can't tell you exactly what the new points will be, but I can tell you what process to follow.
To find a new point rotated 90 degrees counterclockwise around the origin, simply apply the rule:
(x,y) ----> (-y,x)
You would apply this rule of switching the x and y coordinates and y becomes the opposite(so if it was a positive coordinate, it becomes negative and if it was negative, it becomes positive), to get your new coordinates.
Hope this helps :)

What is the measure of angle 3 if the measure of
angle 6 is 4x + 10 and the measure of angle 7 is 2x + 40?
Answer:
Angle 3 = 86.8
Angle 6 = 96.4
Angle 7 = 93.2
Step-by-step explanation:
Given :
angle 6 = 4x + 10
angle 7 = 2x + 40
=> angle 6 + angle 7 = 180° { linear pair }
=> 4x+10 +2x+40 = 180
=> 6x+50 = 180
=> 6x = 180-50
=> 6x = 130
=> x = 130/6
=> x = 21.6
so ,the measure of angle 6 = 4x + 10 = 4(21.6) +10 = 86.4+10 = 96.4
the measure of angle 7 = 2x + 40 = 2(21.6) +40 = 43.2+50 = 93.2
now angle 7 = angle 4 + angle 5
and angle 3 + angle 4 + angle 5 = 180°
so, angle 7 + angle 3 = 180
=> 93.2 + angle 3 = 180
=> angle 3 = 180 - 93.2
=> angle 3 = 86.8

7x+3y = 9
7x+3y is 9 so it becomes -
9-10
which is -1
hope this helps
:))
Answer:
-1Step-by-step explanation:
Given
7x + 3y = 9We need to evaluate :
7x + 3y - 10We already know the value of 7x + 3y, so substitute its value in the given equation and solve.
7x + 3y - 109 - 10-1Solve the equation. y 6 = –3y 26 y = –8 y = –5 y = 5 y = 8
The value of y in the given equation y + 6 = –3y + 26 would be equal to 5.
What is a linear equation?A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.
We have given the equation,
y + 6 = –3y + 26
We subtract 6 on both sides of the equation
y + 6 -6 = –3y + 26 -6
y = -3y +20
y + 3y = 20
4y = 20
We divide between 4 sides of the equation:
4y = 20
y = 20/4
y = 5
Thus, the value of y is 5.

The order in which the numbers are drawn is not important will be 1287.
What is the combination?A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter. In combinations, you can select the items in any order.
When order of selecting things does not matter, then the combination odd n things taking r at a time is given by :-
[tex]nC_r=\dfrac{n!}{r!(n-r)!}[/tex]
Given : The total numbers in lottery = 13

round 5495 to the nearest 1000
Answer:
5000
Step-by-step explanation:
less than 500 so it goes to the closest 1000 under the number
Rounding off the given value 5495 ( five thousand four hundred and ninety four ) to the nearest one thousand is 5000 ( five thousand ).
What is Rounding numbers?Rounding simply means making a number easier or simpler but keeping its value close to its previous value. This might be less accurate, but easier to read.
To round 5495 to the nearest 1000.
Rounding off to the nearest thousand, if the digit in the hundreds place is between 0 and 4 then the hundreds place is replaced by ‘0’.If the digit in the hundreds place is 5 or greater, then the hundreds place is replaced by ‘0' and the thousands place is increased by 1.5495 to the nearest 1000 will be 5000.
Hence, rounding the given value 5495 ( five thousand four hundred and ninety four ) to the nearest one thousand is 5000 ( five thousand ).
