Answer:
5
Step-by-step explanation:
When a square root of an expression is multiplied by itself, the result is that expression
5=x
Answer:
x = 5 , y = 5
Step-by-step explanation:
Using the sine and cosine ratios in the right triangle and exact values.
sin30° = 
, cos30° = 
, then
sin30°= 
= 
= ( cross- multiply )
2x = 10 ( divide both sides by 2 )
x = 5
and
cos30° = 
= 
= ( cross- multiply )
2y = 10 ( divide both sides by 2 )
y = 5
<span>X -1 3 5
y 7 3 1 </span>
avgroc = ( 1 -7) / (5 - -1) = -6/6 = -1
1 hour = 3600 seconds
3 × 3600 = 10800
<span>10800 yards per hour

1 mile = 1760 yards
10800 ÷ 1760 = 6.13
6.13 miles per hour
Answer:
58$
Step-by-step explanation:
1 - 0.35x = 20.30
2 - x = 20.3/0.35
3 - x = $58.00
