$x-\ number\\\\
\frac{x-9}{2}=4\ \ \ |Multiply\ by\ 2\\\\
x-9=8\ \ \ |Add\ 9\\\\
x=17\\\\Number\ is\ 17.$

$(x-9):2=4 \\\\ x-9=4*2 \\\\ x-9=8 \\\\ x=8+9 \\\\ \boxed{x=17}$

95% of 160 I need help with this question

Pani-rosa [81]

You can write it several ways. Here are two:

1) Proportion
160/1.00=x/0.95
(160 is the whole, 1.00 or 100%, and x is 95% of the whole. Solve for x.)
x=160*0.95 = 152/1 = 152
 1.00

2) Simple multiplication expression
"of" in math almost always means "multiply"
95% becomes 0.95. Multiply 0.95 by 160 to get your answer.
0.95*160=152

Either way, you get 152, so that is your final answer.

Can someone help please

Alik [6]

Answer:

Step-by-step explanation:

base + 2(legs) = 56 (2 legs are the same because it's isosceles)

x + 2(5x - 5) = 56

x + 10x - 10 = 56

11x -10 = 56

11x = 66

x = 6

Let A= {a,b,c,d,e} and let B= {1,2,3,4,5} determine n(AxB)

777dan777 [17]

n(AxB) = 25

Step-by-step explanation:

AxB in sets is called Cartesian product. And is defined as a set of ordered pairs (a,b) where a belongs to A and b belongs to B.

Given

A = {a,b,c,d,e}

B = {1,2,3,4,5}

The number of elements for Cartesian product of two sets is determined by:

$n(AxB) = n(A) * n(B)$

Here

$n(A) = 5\\n(B) = 5$

So,

$n(AxB) = 5*5 = 25$

Hence,

n(AxB) = 25
