Answer:

3/5 + 7/10 =  6/10 + 7/10 = 13/10 = 1 and 3/10 lbs. needed

She has 4/5 *3/1 bags = 12/5 = 2 and 2/5  pounds

2 2/5 - 1 3/10  = 2  4/10 - 1 3/10 = 1 and 1/10 pounds  left over

What monomial multiplied by - 3x ^ 3 * y equals 18x ^ 9 * y ^ 4 Explain how you were able to determine the coefficient and the e
Archy [21]

Answer:

-6x^6y^5

Step-by-step explanation:

you have to find p such that

(-3x^{3}y)(p) = 18x^{9}y^{4}

So just divide to find p

p = \frac{18x^{9}y^{4} }{-3x^{3}y} = -6x^{6}y^{5}

Substitution method<br>4x + y = 14<br>6x - 3y = 3​
lakkis [162]

Answer:

  • x = 2.5
  • y = 4

Step-by-step explanation:

<u>We know that:</u>

  • 4x + y = 14
  • 6x - 3y = 3

<u>Let's first solve for y by choosing any equation.</u>

  • 4x + y = 14
  • => y = 14 - 4x

<u>Now, let's substitute the value of y into the second equation.</u>

  • 6x - 3y = 3
  • => 6x - 3(14 - 4x) = 3
  • => 6x - 42 + 12x = 3
  • => 18x - 42 = 3
  • => 18x = 42 + 3
  • => 18x = 45
  • => x = 45/18 = 5/2 = 2.5

<u>Now, let's substitute the value of x into the equation of y.</u>

  • => 14 - 4x = y
  • => 14 - 4(2.5) = y
  • => 14 - 10 = y
  • => y = 4

Hence, the value of x and y are 2.5 and 4 respectively.

Solve for (y)(x)<br> x-y=1<br> 1/2x+y=5
TEA [102]
Using addition

x-y+1/2x+y=1+5
x+1/2x+0y=6
3/2x=6
\frac{3}{2}x=6
3x=12
x=4

Using the value of x
x-y=1
4-y=1
y=3

With x as 4 and y as 3, their product is 12
And can be written as (4,3)
