Answer:
9, 4.5 x 2 = 9
4.5 = 45 tenths and 0.5 = 5 tenths
5 tenths x 9 = 45 tenths
4.5/0.5 = 9
6.3/0.9 = 7, 0.9 x 7 = 63, 63 / 0.9 = 7
Step-by-step explanation:
Answer:
what's the question ?
Step-by-step explanation:
<span>Answer:
If using A, B, C, as variables for the measure of the corresponding interior angles, and A is the vertex point, B and C are the base angles, triangle isosceles, then:
system%28A=4y%2B10%2CB=75%2CC=3x%29
Angle mesures at B and C are equal (base angles of isosceles triangle).
B=C
75=3x
highlight%28x=25%29</span>
1. 45
write the consecutive numbers as x, x+1 and x+2 as its a sum 3x+3=138 so 3x+135 and x=45
2.$4
27-3=24, 6 candy bars for $24 dollars so $4 each
3. 6 hours
59-11 initial fee is $48 at a rate of $8 per hour, 48/8 is 6hours
4.52
29 is half of what he had once getting 6 new cards
so 58-6 52 giving the original number
5.27
using the same method as 1
6.21
odd numbers must be written as 2n+1,2n+3,2n+5
the sum 6n+9 =69
n=10
2n+1=21
7. 12
12-6 =6
6x2=12
8.$6
12-9=3
this is half the allowance so the is 3x2=6
9.57
291-6=285 is the number in all 5 buses total
285/5=57 students per bus
10.19
184-13= 171 dollars spent on all nine books
171/9=19 per book
