Step-by-step explanation:
add right sides of equation and even them with result of adding right sides of equation
4x-4y-9x-4y=-2-3
-5x-8y=-5
Answer:
x is 36
Step-by-step explanation:
the way to find out is 1/4 multiplied by what gives you 9. 9 divided by 1/4 is 36. 36 1/4's gives you 9.
Everything on this whole sheet is unit rates. Everything ! For the 2 carpenters, find the unit rate for each one (windows / hours), then see if one carpenter is doing more windows per hour than the other one. Don't forget THE RULE I gave you yesterday, when we were doing the detergent and the peanut butter.
Answer:
cscФ = 13/12
Step-by-step explanation:
∵ The terminal side of the angle Ф passes through point (5/13 , 12/13)
∵ x = 5/13 and y = 12/13
∵ x = cosФ and y = sinФ
∴ cosФ = 5/13
∴ sinФ = 12/13
∵ cscФ = 1/sinФ
∴ cscФ = 1 ÷ 12/13 = 13/12
