Answer:
C, x + 20 = 41
Step-by-step explanation:
X represents the number of small sea shells that we originally had. When the family adds 20 more shells, that makes x + 20. The total number is 41, so that means the number of sea shells they already had (x) plus the number of sea shells they collected (20) equals the number of shells they have now (41).
Answer:
21.6 $ / h
Step-by-step explanation:
Since it is a raise you'll calculate by multiplying the $ / h by (1 + % / 100)
In this case 1 + % / 100 = 1 + 20 / 100 = 1 + 0.20 = 1.20
1.20 * 18 = 21.6 $ / h
NB.:
If it was a decrease by 20 % => 1 - 20 / 100 = 1 - 0.20 = 0.80
You would multiply the $ by 0.80.
Answer:
38
Step-by-step explanation:
The sum of the measures of the 4 angles is 180°.
m<A + m<B + m<C + m<D = 180
60 + 2x + 3x + 25 = 180
5x + 85 = 180
5x = 95
x = 19
m<B = 2x = 2(19) = 38
Answer: 38
Answer:i cant see the question 1 < q maybe?
Step-by-step explanation:
Count the number of grids for each side length.
UV = 5 units
VW = 6 units
Now, for UW use the pythagoras theorem to calculate.
Therefore, the perimeter is 5 + 6 + 7.8 = 18.8 units.
