Answer:
This distance would be <u>14 cm</u> long.
Step-by-step explanation:
2 cm = 35 km
1 cm = 35/2 = 17.5 km
Let's assume: x -> the distance on a map (in cm)
so:
x * 17.5 = 245
x = 245/17.5 = 14 (cm)
the answer is 5 if you need an explanation ask for it in the comments
All you have to do is subtract 18 from 45 and divide that sum by 3, because 3 bags of birdseed were bought. If she spent $45, then 18 dollars were spent on a birdfeeder and three bags of birdseed costs $27 all together. 27 divided by 3 is 9, so each bag of birdseed costed $9. :)
Answer:
Correct option is
B
1.x+0.y=7
x=7 can be written as, 1.x+0.y=7 as the coefficient of x is 1 and that of y is 0. Step-by-step explanation:
Answer:
Step-by-step explanation:
1. Since, it is given that ABCD is a parallelogram, therefore opposite angles of parallelogram are equal, hence
∠B=∠D
⇒7x-31=5x+13
⇒2x=44
⇒x=22
Hence, option B is correct.
2. Since, we get x=22, therefore
∠B=7x-31=7(22)-31=154-31=123°
∠B=123°
and ∠D=5x+13=5(22)+13=123°
∠D=123°
Also, ∠A+∠D=180°(corresponding angles)
⇒∠A=180-123
⇒∠A=57°
Now, ∠A=∠C=57°(opposite angles of parallelogram)
thus, Two of the angles measure 57°, and the other two measure 123°.
Therefore, option A is correct.
