A) 4*x + 3*y = 64
B) x + y = 19
B) x = 19 - y Substituting B into A
A) 4*(19 -y) + 3*y = 64
76 -4y + 3y = 64
-y = -12
y =12
x = 7

b. M =0.60x

c. $43.2

d. $1416.67

Step-by-step explanation:

Given that:

The World Issues club donates 60% of the total of their fundraising activities.

Answer a.

Let us choose the variable x to represent the money earned during fundraising activities and M for the revenue generated for foundation.

Answer b.

Foundation will receive 60% of the total of the fundraising activities.

Equation to determine the money that will be received by foundation:

M = 60\%\ of\ x\\OR\\M = 0.6x

Answer c.

Given that x = $72, M = ?

Putting the value of x in the equation above:

M = 0.6 \times 72\\\Rightarrow \$43.2

Answer d.

Given that M = $850, x = ?

Putting the value of M in the equation above to find x:

850= 0.6 \times x\\\Rightarrow x = \dfrac{850}{0.6}\\\Rightarrow x = \$ 1416.67

So, the answers are:

a. Let the variable be x for the fundraising activities and M as the revenue for foundation.

b. M =0.60x

c. $43.2

d. $1416.67

Convert y-3=(1/3)(x+1) to slope intercept form
Mekhanik [1.2K]
Slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.

Here, we first need to distribute the 1/3.

y-3= \frac{1}{3} x+\frac{1}{3}

Next, we add 3 to both sides of the equation.

y= \frac{1}{3} x+\frac{10}{3}

What would be the equation and how can I solve it
Blababa [14]
If alonzo is x then the equation is

x + (x +3) + 2(x + 3) = 57

Which equals

x + x + 3 + 2x + 6 = 57
4x + 9 = 57
4x = 48
x = 12

This means alonzo is 12 years old and alexis is 3 years older so alexis is 15 years old

Answer = 15 years old

If you drew a marble from a bag containing 24 marbles and you had a 1/3 probability of drawing a red marble, how many red marble
Masja [62]
Hello there.

Question: <span>If you drew a marble from a bag containing 24 marbles and you had a 1/3 probability of drawing a red marble, How many red marbles are in the bag?

Answer: 1/3 is just a simplified version of the original fraction.
To find this out, get the denominator to the total of 24.
24 / 3 = 8.
You multiply the bottom by 8 therefore you need to do the same to the top.

In short, Your answer is </span>\frac{8}{24}.
The number of red marbles is 8.

Hope This Helps You!
Good Luck Studying ^-^
