Which steps will generate an expression equivalent to 17(+5)

Bingel [31]

For this case we must indicate an expression equivalent to:

$17 (x + 5)$

By definition we have that the distributive property establishes that:

$a (b + c) = ab + ac$

Then, applying the property to the given expression we have:

$17 (x + 5) = 17 * x + 17 * 5 = 17x + 85$

Thus, an equivalent expression is:

$17x + 85$

ANswer:

$17x + 85$

Simplify the following expression.( Fraction form) 7-5/6 * 7-7/6

Ipatiy [6.2K]

Answer:

1295/36

Step-by-step explanation:

the statement tell us:

(7-(5/6))*(7-(7/6))

we have:

(7-(5/6))=((6*7)-5)/6=(42-5)/6=37/6

and we have:

(7-(7/6))=((6*7)-7)/6=(42-7)/6=35/6

we need multiply both terms:

(37/6)*(35/6)=(37*35)/(6*6)

finally we have

1295/36

What are the intercepts of the line 3x – 15y = 60? A. x-intercept: –4; y-intercept: 20 B. x-intercept: –3; y-intercept: 15

AnnZ [28]

X intercept is when y = 0
3x -15(0) = 60
3x = 60
x = 20

y intercept is when x=0
3(0) -15y = 60
-15y = 60
y = -4

Answer is C
