Equation: 49 = 150 - 150(x)

Steps to Solve:

49 = 150 - 150(x)

-101 = -150x

x = 0.6733 or 67.33%

The sterling and diamond bracelet is approximately 67.33% off.

Let's use the furthest left point on the triangle to figure out the translation.

Blue triangle = (-5,1)

Black triangle = (-3,-1)

To get from -5 to -3 we moved the triangle 2 units to the right, which means that we added 2.

To get from 1 to -1, we moved the triangle 2 units down, which means we subtracted 2.

Rule: {2, -2}

Hope this helps!

In a contest to guess the number of jelly beans in a jar, Alice guessed 25;Betty, 18;Clare,23;Dotty,19;Edith,24;and Fran,17. Two

vampirchik [111]

Answer:

<em>There are 21 jelly beans in the jar.</em>

Step-by-step explanation:

Suppose, the number of jelly beans in the jar is $x$

Two were off by 2, two were off by 3, two were off by 4. That means, the six guessed number will be: $(x+2), (x-2), (x+3), (x-3), (x+4), (x-4)$

Given that, Alice guessed 25; Betty, 18; Clare, 23; Dotty, 19; Edith, 24; and Fran, 17.

So, the sum of all six guessed number will be: $25+18+23+19+24+17=126$

Thus, the equation will be..........

$(x+2)+(x-2)+(x+3)+(x-3)+(x+4)+(x-4)= 126\\ \\ 6x= 126\\ \\ x=\frac{126}{6}=21$

So, the number of jelly beans in the jar is 21.

If M=5x^2+7x-4 and N=-3x^2-4x+5, then M-N equals

Phantasy [73]

Answer:

8x² + 11x - 9

Step-by-step explanation:

M - N

= 5x² + 7x - 4 - 1(- 3x² - 4x + 5) ← distribute parenthesis by - 1

= 5x² + 7x - 4 + 3x² + 4x - 5 ← collect like terms

= 8x² + 11x - 9

Round 17.641 to the nearest whole number

vfiekz [6]

The nearest whole number would be 18 because the 6 is greater than 5. Anything greater than five, would most likely be rounded to the nearest whole number. Hope this helped!
