Answer:
The temperature needs to decrease by 7°F to return to the original temperature.
Step-by-step explanation:
The temperature starts at 33 degrees then increases by 10 then 12 then decreases by 15 which will equal 40.
33 + 10 = 43
43 + 12 = 55
55 - 15 = 40
40 - 33 = 7
The temperature needs to decrease by 7 degrees.
Answer:
Step-by-step explanation:
The lengths can be found by considering their ratio:
short : long = 1 : 5
The sum of the ratio units is 1+5 = 6, and the sum of the lengths is 144 inches. That means each "ratio unit" stands for (144 in)/6 = 24 inches of length.
The lengths are ...
1 : 5 = 24 in : 120 in
The pieces are 24 inches and 120 inches in length.
__
Equivalently, you can let s represent the shorter length. Then 5s is the longer one, and their total is ...
s +5s = 144
s = 144/6 = 24
5s = 5(24) = 120
The lengths are 24 inches and 120 inches.
3.5x8 = 28 grams have a good day
Step-by-step explanation:
Hey ..but there is nothing from which question can be equated ..
like if they are equal to zero..
or
(4x+45)=(5x-18)
i am giving answer for both scenarios
(4x+45)=0
4x=-45
x=-45/4
x=(-11.25)
(5x-18)=0
5x=18
x=18/5
x=3.6
Incase if they both are equal to each other...
(4x+45)=(5x-18)
(45+18)=(5x-4x)
63=x
x=63
Hope it helps you
Have a nice day
