Answer:
7(4 + y)
Step-by-step explanation:
Answer:
Step-by-step explanation:
Part C- y=20x+600
Part D- To part D find the equations for all the cities.
Everett- y=15x+550
Chelsea- y=20x+600
Revere- y=50x+300
Since 2030 is 14 years away from 2016 x will equal 14.
Plug in 14 to each of the equations. Whichever has the highest result will be the answer.
Everett- y=15(14)+550 -----> y=760
Chelsea- y=20(14)+600 -----> y=880
Revere- y=50(14)+300 -----> y=1000
Revere will have the most chromebooks.
Answer:
(21x^4y + 7x^3y^2 − 28x^2y^2) ÷ 7xy = 3x^3 + x^2y − 4xy
Step-by-step explanation:
(9xy^2 + 12x^3y^4 − 6x) ÷ 3x = 4x^2y^4 + 3y^2 − 2 (False: 9xy^2:3x=3y^2)
25x^4y^2 + 10x^2y^4 − 15y) ÷ 5y = 5x^4y + 2x^3y^2 − 3 (False: 10x^2y^4:5y=2x^2y^3)
(16x^4y^2 + 24x^2y^2 − 8xy^2) ÷ 4xy = 4x^4y + 6xy− 2y(False: 16x^4y^2:4xy=4x^3y)
(21x^4y + 7x^3y^2 − 28x^2y^2) ÷ 7xy = 3x^3 + x^2y − 4xy (True)
Answer:
x = 10
Step-by-step explanation:
Since the triangle is right use the sine ratio to find x
sin30° = 
= 
cross- multiply
x × sin30° = 5 ( sin30° = 0.5 )
0.5x = 5 ( divide both sides by 0.5 )
x = 10
