Mikhael wanted to rewrite the conversion factor "1 yard ≈ 0.914 meter" to create a conversion factor to convert meters to yards.

Nataly [62]

Answer:

$1\ meter = 1.094\ yard$

Step-by-step explanation:

Given

$1\ yard = 0.914\ meter$

Required

Create a convert meter to yard expression

$1\ yard = 0.914\ meter$

Divide both sides by 0.914

$\frac{1\ yard}{0.914} = \frac{0.914\ meter}{0.914}$

$\frac{1\ yard}{0.914} = 1\ meter$

$1.09409190372\ yard = 1\ meter$

$1\ meter = 1.09409190372\ yard$

$1\ meter = 1.094\ yard$ --- approximated

Please help me with this algebra PLEEASSEee!!!

11. 5x^2-30=0
+30 to both sides
5x^2=30
÷5 both sides
x^2=6
square root both sides
x= +square root 6 ,- square root 6

12. 4x^2+10=26
-10 both sides
4x^2=16
÷4 both sides
x^2=4
square root both sides
x=+2,-2

13. a=72yrd^2
l=2w
w=?
a=l×w
72=2w×w
72=2w^2
÷2 both sides
36=w^2
square root both sides
w=+6,-6
a measurement can't be - so w=6
Plug into l=2w
l=2×6

l=12
w=6
