Answer:
2
Step-by-step explanation:
Given the equation :
3x - 2y = 4 - - - (1)
5x + y = 11 - - - (2)
Multiply (1) by 1 and (2) by 2
3x - 2y = 4 - - - - - (3)
10x + 2y = 22 - - (4)
Add (3) and (4)
13x = 26
x = 26/13
x = 2
solve for the number

Step-by-step explanation:
The sum of 3 and a number is between -2 and 17.
Answer:
The number, x = { -5 < x < 14}
This means x is any integer between -5 and 14
Step-by-step explanation:
From the statement, let the number be x
3 + x = y; y = { -2 < y < 17}
This means that y is any integer between -2 and 17
Therefore, x = y - 3
Subtract 3 from the limits of y
i.e. -2 - 3 = -5 and 17 - 3 = 14
Hence, x = { -5 < x < 14}
The line given by the equation y=x is shifted up 3 units and more steep by a factor of 2. What is
the equation of the new line?
y = 2x - 3
y = 2x- 3
y =1/2x -3
y = 1/2x + 3

Step-by-step explanation:
Which expression uses the greatest common factor and the distributive property to write the sum 36 1 54 as a product? A 6(6 1 9) B 9(4 1 6) C 18(2 1 3) D 27(9 1 27)
9514 1404 393
Answer:
C 18(2 + 3)
Step-by-step explanation:
The GCD of 36 and 54 is their difference, 18. Factoring that out of the sum, you have ...
36 + 54 = (18·2 + 18·3) = 18(2 + 3) . . . . matches choice C
Find the slope of the line 0,-19 20,15
I need help, please
Answer:
C
Step-by-step explanation:
12^2 = 144, 9^2 = 81, and 15^2 = 225.
144 + 81 = 225, therefore a^2 + b^2 = c^2.

Find the values of X and Y.
Given:
A figure.
To find:
The value of x and y.
Solution:
In triangle ADC, all angles are equal, so it is an equilateral triangle.
We know that, all sides of an equilateral triangle are equal.
[tex]AD=AC[/tex] ...(i)
[tex]3x-5=5y-4[/tex] ...(ii)
In triangle ABD,
[tex]\angle BAD=\angle ABD[/tex]
Base angles are equal, so triangle ABD is an isosceles triangle.
[tex]AD=BD[/tex] ...(iii)
Using (i) and (iii), we get
[tex]AC=BD[/tex]
[tex]5y-4=y+12[/tex]
[tex]5y-y=4+12[/tex]
[tex]4y=16[/tex]
Divide both sides by 4.
[tex]y=4[/tex]
Putting y=4 in (ii), we get
[tex]3x-5=5(4)-4[/tex]
[tex]3x-5=20-4[/tex]
[tex]3x-5=16[/tex]
Adding 5 on both sides, we get
[tex]3x=16+5[/tex]
[tex]3x=21[/tex]
Divide both sides by 3.
[tex]x=7/tex]
Therefore, the value of x is 7 and the value of y is 4.
Bobby, Rachel, and Sherry are going to have a water battle.
- Bobby fills his bucket at a rate of 3/4 gallon in 2 minutes.
- Rachel can fill her bucket at 1/5 gallon in 1/2 minute.
- Sherry can fill 3/8 gallon in 3/4 minute.
Order from fastest to slowest.
Answer:
The order is
Sherry >> Rachel>>Bobby
Step-by-step explanation:
Step one:
We want to find the smallest unit rate
given data
1. Bobby fills his bucket at a rate of 3/4 gallon in 2 minutes.
unit rate
=3/4/2
=3/4*1/2
=3/8
=0.375 gallons per minute
2. Rachel can fill her bucket at 1/5 gallon in 1/2 minute.
unit rate
=1/5/1/2
=1/5*2/1
=2/5
=0.4 gallons per minute
3. Sherry can fill 3/8 gallon in 3/4 minute.
unit rate
=3/8/3/4
=3/8*4/3
=12/24
=0.5 gallons per minute

Answer:
y int is (0,5)
slope is m=-2
y=-2x+5
Step-by-step explanation:
The line has a slope of -2 and a y-intercept of y=4. (y=-2x+4)
Explanation: You can tell by where the line is landing on the x and y intercepts and it's as easy as counting lines. As far as the y-intercept goes, you can tell that by looking where the line crosses the y axis. And in this case it's (0,4) making your y-intercept, y=4.

which expression is equivalent to
2(3g-4)-(8g+3)?
-2g-1
-2g-5
-2g-7
-2g-11
Answer:
-2g - 11
Step-by-step explanation:
Expand the brackets, multiply 2 over 3g and -4. One plus and one minus make a minus.
2(3g-4) - (8g+3) = 6g - 8 - 8g - 3
Evaluate like terms.
6g - 8 - 8g - 3 = -2g - 11
The sum of three times a number and -4 is at least twice the number plus 8
Answer:
x<=12
Step-by-step explanation:
3x+(-4)<=2x+8
3x-4<=2x+8
3x-2x-4<=8
x-4<=8
x<=8+4
x<=12
Answer:
12 ≤ x
Step-by-step explanation:
3x-4 ≥ 2x+8
3x-3x-4 ≥ 2x-3x+8
-4-8 ≥ -1x+8-8
-12 ≥ -1x
You divide -1 on both sides and get...
12 ≤ x
Because you have to switch the sign around. I hope this helps!!
