otez555 [7]

Answer:

After 4 days, the number of people attending both conferences be the same.      

Step-by-step explanation:

We are given the following in the question:

Maths conference:

Number of people already signed = 7

Number of people who sign up each day = 2

Thus, the number of people who will sign up for maths conference in x days will be given by the linear function:

 f(x) = 7+2x

History conference:

Number of people already signed =11

Number of people who sign up each day = 1

Thus, the number of people who will sign up for maths conference in x days will be given by the linear function:

 g(x) =11+x

Both conference will have same number of people when

f(x) = g(x)\\\Rightarrow 7 + 2x = 11+x\\\Rightarrow x = 4

Thus, after 4 days, the number of people attending both conferences be the same.

You are wrapping boxes for a fund-raiser. You have 80 large boxes. You need 2 and three-fourths feet of ribbon for each large bo
Ratling [72]

Answer:

5 rolls of ribbon are needed

Step-by-step explanation:

To find how much ribbon you'll use, multiply 80 by 2 3/4. To multiply them, convert 2 3/4 into an improper fraction 11/4.

Multiply: 80 * 11/4 = 880/4 = 220

This means you need 220 total feet of ribbon. Since each roll has 50 feet, you'll need 5 rolls or 250 feet to wrap every box.

Solve for x.<br> z=(x-7)k
aliya0001 [1]

Answer:

x=\frac{z}{k}+7

Step-by-step explanation:

we have

z=(x-7)k

solve for x

That means ----> isolate the variable x

Divide by k both sides

\frac{z}{k}=x-7

Adds 7 both sides

\frac{z}{k}+7=x

Rewrite

x=\frac{z}{k}+7
