I got 1.1... is that right?

No, the answer is 2

X=2

This is because if we multiply the number by x which is 2

so DST is 110, and RSD is 44, so that is 154, and if we do it with RST we also get 154

So the correct answer is X=2

AC=(5x+12) and BD =8x? Can somebody help me to slove it

AleksAgata [21]

To solve this equation from the information given above, I ordered it 5x+12=8x. To solve, I subtracted 5x from each side, canceling the 5x to your left, leaving only the number 12. 8x minus 5x equals 3x. Take 3x and divide on both sides. 3x/3x cancels the 3, leaving 12/3 equals 4. Finally, x equals 4.

Rx+h=sx-k solve for x

timama [110]

Rx + h = sx - k Take all with x to the LHS

Rx - sx = -k - h

x(R - s) = - k -h

x = (-k - h) / (R - s). Multiply top and bottom by -1.

x = (k + h) / (s - R)

<span>1) What is the equation for the line?
</span>slope = 16/2 = 8

answer
equation
y = 8x

<span>2) What is the equation of a line with a slope of 3 and a point (3, 1) on the line?

Express the equation in the form of y=mx+b where m is the slope and b is the y-intercept.

y - 1 = 3(x - 3)
y - 1 = 3x - 9
y = 3x - 8

answer
</span>y = 3x - 8

PLEASE HELP WILL GIVE BRAINLIEST AND 20 POINTS

1250 lbs of sand.

So first let's find the volume of the sand in the sandbox. You have a square sandbox, with a side length of 5, meaning you have a length and width of 5. You also have half a foot of sand in the sandbox, meaning that you have a height of 0.5. To find the volume of the sand, multiply the length by the width by the height:

$5 * 5 * .5 = 12.5$

So you have 12.5 cubic feet of sand. If each cubic foot of sand is 100 lbs, then you just multiply the two:

$12.5 * 100 = 1250.0
