Find missing number from letter n ! Please

Ira Lisetskai [31]

Answer:

1. n= 20 /13

2. n=10

3. n=35

4. n=9

That's all I could do, I got tired of typing lol

Step-by-step explanation:

1. 4/n=13/5 we cross multiply, (4)*(5)=13*n, 20=13n Flip the equation. 13n=20, divide 13 on both sides, 13n/13=20/13, n= 20 /13

2. 9/6= 15/n, we cross multiply 9*n=(15)*(6), 9n=90, Divide both sides by 9. 9n/9=90/9 n=10

3. 28/4=n/5 Cross-multiply, (28)*(5)=n*(4), 140=4n Flip the equation.4n=140 Divide both sides by 4. 4n/4=140/4 n=35

4. n/6=6/4 we cross multiply,n*(4)=(6)*(6), 4n=36, Divide both sides by 4 4n/4=36/4. n=9

The cook needs to make the dough for 9 small pizzas. Each pizza dough needs 1 1/3 cup of flour. How much flour does the cook n

omeli [17]

If each pizza dough needs 1 $\frac{1}{3}$ \\
We will need to multiply 9 x 1 $\frac{1}{3}$ \\

we will turn the fraction into a mixed fraction and we'll end up with $\frac{4}{3}$ \\

We multiply 9 x $\frac{4}{3}$
and we end up with $\frac{36}{3} = 12$

The cook need 12 cups of flour.

Find the exact solution of 3x^2+7=28

Softa [21]

$\text{Solve:}\\\\3x^2+7=28\\\\\text{Subtract 7 from both sides}\\\\3x^2=21\\\\\text{Divide both sides by 3}\\\\x^2=7\\\\\text{Square root both sides}\\\\\sqrt{x^2}=\sqrt7\\\\x=\pm\sqrt7\\\\\boxed{x=\sqrt7\,\,or\,\,x=-\sqrt7}$
