The difference between two numbers is 7. The sum of twice the larger number and three times the smaller number is 19.
Alex17521 [72]

Answer:

x= 8   y= 1

Step-by-step explanation:

First, you identify your variables:

x= larger number

y= smaller number

Second, you find your equations:

x - y = 7

2x + 3y = 19

Third, (I used the substitution method) you make "y" by itself for the 1st equation.

y = x - 7

2x + 3y = 19

Then, you plug in the 1st equation for "y" in the 2nd equation

2x + 3(x - 7) = 19

Then, you distribute and simplify.

2x + 3x - 21 = 19

5x - 21 = 19

5x = 40

x = 8

Finally, you plug in the variable you found ( x ) into one of the equations and solve,

8 - y = 7

- y = -1

y = 1

Find the surface area of a rectangular prism measuring<br> 5 m by 8 m by 9 m.
olganol [36]
The formula of the surface area of the rectangular prism is equal:
A=2(wl+wh+lh)
where:
l - length
w - width
h - height
We have:
l = 5m
w = 8m
h = 9m
Substitute:
A=2\cdot(5\cdot8+5\cdot9+8\cdot9)=2\cdot(40+45+72)=2\cdot157=314\ m^2

Mario has LaTeX: 2\frac{1}{4}2 1 4 pounds of trail mix. He puts equal amounts of the trail mix into 6 bags for a hike with his f
ioda

Answer:

<h2><em>0.375 pounds </em></h2>

Step-by-step explanation:

Let the amount of trail mix in each bag be x pounds. If Mario has 2\frac{1}{4} pounds of trail mix and puts equal amounts of the trail mix into 6 bags for a hike with his friends, the amount of trail mix in each bag can be derives using the expression;

2\frac{1}{4} = 6 * x

solving for x

\dfrac{9}{4} = 6x\\\\2.25 = 6x\\\\divide\ both \ sides \ by \ 6\\\\\dfrac{2.25}{6} = \dfrac{6x}{6} \\\\x = 0.375\\

<em>Hence 0.375 pounds of trail mix will be in each bag</em>

Answer: 41 2 point shots

Step-by-step explanation: First multiply 41 times 2 since it is two games. Next divide that number by two. Since you don’t have any left over it is just 41.

41 x 2 = 82

82 ÷ 2 = 41
