Answer:
-1
Step-by-step explanation:
2y+6=1 -3y
add three to both sides and minus 6 from both sides becasue you want to get y by itself
5y=-5
now both sides by 5
y=-1
Answer:
800m
Step-by-step explanation:
this would be solved using Pythagoras theorem
we are to find the base
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
600² + b² = 100²
b² = 10000 - 3600
b² = 6400
take the square root of both sides
b = 800m
Answer:
The answer is 52.
Step-by-step explanation:
Subtract 56 by 4. You'll get 52.
Answer:
BC ≈ 4.85 m
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos26° = 
= 
= 
( cross- multiply )
5.4 × cos26° = BC , then
BC ≈ 4.85 m ( to 3 s f )

Divide the euros by the dollar amount:
35 / 45.00 = 0.777 = 0.78 Euros per dollar.
12. the 1/2 bag covered 1/10 of her yard, her entire yard would be equal to 10/10 , this means she would need ten 1/2 bags.
10 x 1/2 = 10/2 = 5 bags.
14.
1 mile divided by 3/8 mile = 2 2/3.
Multiply 2 2/3 by 1/16 to get how much water was needed for 1 mile:
2 2/3 x 1/16 = 1/6 gallon for 1 mile.
Now they want miles per gallon, there are six 1/6's in a gallon.
Multiply 6 by the number of gallons per 1/6:
6 x 1 = 6 miles per gallon.
