If Teri ran 8 kilometers. Which measurement of miles Teri ran

1 answer:

6 0

There is 0.62137119 miles to 1 kilometer so 8 kilometers = 4.971 or (5 miles rounding) multiply 0.6 x 8 = 4.971 but u can sensibly say 5 miles

What value in the replacement set is a solution to this equation? 3(n+7)=48. Replacement set {8,9,10.

Studentka2010 [4]

So if the 3 is on the outside of the parenthesis 3( it means you have to multiply 3 times the numbers inside the parenthesis. 3 X n+7 + 3n + 21. hope this hint helps.

Find all of the missing angles... Just find as many as you can please anything will help.

Anastasy [175]

A = 180 - 143 = 37
b = 143
c = a = 37
e = a = 37
f = 90 - 37 = 53
d = 180 - 85 - 37 = 58
g = 48
h = 180 -48 -48 = 84
k = 180 -84 = 96
m = 180 - 58 - 96 = 26
p = 180 - 26 - 85 = 69
r = 180 -69 = 111
s = p = 69

Simplify the following expressions

LenKa [72]

Answer:

1. $8x+5$
2. $2x^2-9$

Step-by-step explanation:

Given the following questions:

$(2x^2+5x-2)+(-2x^2+3x+7)$
$(2x^2+5x-2)-(5x+7)$

In order to find the answer to these questions we have to group the terms with the same variables and then combine like terms. Of course, applying the distributive property if needing to do so.

Number one:
$(2x^2+5x-2)+(-2x^2+3x+7)$
$(2x^2+5x-2)+(-2x^2+3x+7)=2x^2+5x-2-2x^2+3x+7$
$2x^2+5x-2-2x^2+3x+7$
$2x^2-2x^2+5x+3x-2+7$
$2x^2-2x^2=0$
$5x+3x-2+7$
$-2+7=5$
$5x+3x+5$
$5x+3x=8x$
$8x+5$

Number two:
$(2x^2+5x-2)-(5x+7)$
$(2x^2+5x-2)-(5x+7)=2x^2+5x-2-\left(5x+7\right)$
$2x^2+5x-2-\left(5x+7\right)$
$2x^2+5x-2-5x-7$
$2x^2+5x-5x-2-7$
$5x-5x=0$
$2x^2-2-7$
$-2-7=-9$
$2x^2-9$

Hope this helps.
