Answer:
B. 72 cm by 108 cm
Step-by-step explanation:
We know scale is 4 cm:30 ft. So find how many time 30 ft goes into each measurement of playground and then multiply that by 4...
540/30=18
18×4=72
810/30=27
27x4=108
Answer:
a = $17.25
Step-by-step explanation:
let the money spend on the necklace be a
we have
15.75 +1.5*2 +a + 14 = 50
-> a = 50 -15.75 -3-14
-> a = $17.25
3x would have to be 15/2.
Since we have that 5x+3x=5x+15/2, the only pieces that are different are the 3x and the 15/2. This gives us the equation
3x=15/2
If we were to go on and solve this equation, we would multiply by 2, giving us
6x=15
Then we would divide by 6:
6x/6=15/6
and x=2.5.
