Answer:

600 words

Step-by-step explanation:

To solve this problem, we need to cross multiply. Lets input the values (100, 2.5, 5) as shown below:

\frac{100}{2.5}=\frac{x}{15}

Next we cross multiply. We multiply 2.5 and x, and we multiply 100 and 15.

2.5(x)=2.5x

100(15)=1,500

Now, lets put the values above back into the equation:

2.5x=1,500

Our next step is to divide 1,500 by 2.5 to get <em>x</em> by itself.

x=\frac{1,500}{2.5}

x=600

Sylvia can type 600 words in 15 minutes.

Complete the steps 4/9 divided by 1/2
DedPeter [7]

Answer: 0.88 (the 8 recurs)

Step-by-step explanation:

\frac{4}{9}÷\frac{1}{2}

\frac{4}{9}×\frac{2}{1}  (Then the the fraction should reciprocal so the values should shift to          the opposite side were 2 goes up and 1 goes down and the sign turns to the multiplication sign)

then u should multiply the two fractions which gives 8/9

next you should divide 8 by 9 which gives 0.88(the number eight is recurring which means that the number 8 keeps repeating no matter how many times you try to divide)

Solve for n.<br><br> 11(n – 1) + 35 = 3n<br><br> n = –6<br> n = –3<br> n = 3<br> n = 6
RSB [31]
Solve for n
Simply both sides 11(n-1)+35=3n
Distribute (11)(n) + (11)(-1) + 35 = 3n
11n+-11+35=3n
Combine like terms (11n)+(-11+35)=3n
11n + 24 =3n
Subtract 3n from both sides
11n+24-3n=3n-3n
8n + 24 = 0
Subtract 24 from both sides
8n+24-24=0-24
8n = -24
Divide both sides by 8
8n = -24
8 8
n = -3
