Carolyn is using the table to find 360% of 15. What values do X and Y represent in her table?
Ganezh [65]

★  100% of 15 = X

\implies \mathsf{100\%\;of\;15 = \left(\dfrac{100}{100} \times 15\right) = 15}

\implies \mathsf{X = 15}

★  20% of 15 = Y

\implies \mathsf{20\%\;of\;15 = \left(\dfrac{20}{100} \times 15\right)}

\implies \mathsf{20\%\;of\;15 = 3}

\implies \mathsf{Y = 3}

<u>Answers</u> : X = 15 and Y = 3

Hoochie [10]
Answer:
The graph in the attached figure
Step-by-step explanation:
Let
x -----> the number of boys
y -----> the number of girls

----->inequality A
The solution of the inequality A is the shaded area above the solid line
The slope of the solid line is positive
The y-intercept of the solid line is (0,-5)
The x-intercept of the solid line is (5,0)
-----> equation B
The solution of the inequality B is the shaded area above the dashed line
The slope of the dashed line is negative
The y-intercept of the solid line is (0,4)
The x-intercept of the solid line is (4,0)
using a graphing tool
the solution of the system of inequalities is the shaded area between the solid line and the dashed line

Solve the following system of equations algebraically:<br> x + 4y = 2<br> y = 2x + 14
loris [4]

Answer:

x = -6

Step-by-step explanation:

You can insert the second equation in for the y-variable in the first equation

x + 4(2x+14) = 2

The next step is to distribute the 4

x + 8x + 56 = 2

Then we combine like terms

9x + 56 = 2

Subtract 56 from both sides

9x = -54

Divide by 9 on both sides

x = -6

Y * x = 20<br><br> y + x = 9 <br><br> what numbers are y and x equal to?
Ksivusya [100]

y = 9 - x
Substitute into
y \times x = 20 \\ (9 - x) \times x = 20 \\  { - x}^{2}  + 9x = 20 \\  {x}^{2}  - 9x  + 20 = 0 \\ (x - 5)(x -4) = 0 \\  x = 5 \: or \: x = 4
When x = 5,
y = 9 - 5 \\ y = 4
When x = 4,
y = 9 - 4 \\ y = 5

x = 5, y = 4
x = 4, y = 5

Hope this helps. - M
