Answer:
15/4
Step-by-step explanation:
5 = 5/1
Then you just multiply across, 5*3=15 and 1*4=4 so you get 15/4.
Answer:
Step-by-step explanation:
let the no of girls be x
ratio of boys to girls=4:7
4/7=16/x
do cross multiplication
7*16=x*4
112=4x
112/4=x
28=x
therefore there are 28 no of girls.
Hello there!
Surface Area = 4pir^2
First, we need to find our radius, since we have our diameter all we need to do is divide it by 2. That means, 10 divided by 2 equals 5.
Our radius is 5.
Now, we can plug it into the formula.
4(3.14)(5^2)
4(3.14)(25)
4(78.5)
4(78.5) = 314
Now, convert into pi.
314 = 100pi or 100Π
Gale (g) has (=) 3 less than (-3) 2 times as many stickers as robin (2r)
g=-3+2r
g=25
25=2r-3
add3 to both sdies
28=2r
divide by 2
14=r
robin has 14
To simplify this, we first need to distribute the negative sign to the (x+6). It's easier to see if we rewrite the negative as -1:
Now combine like terms:
