Can some one pls help
solniwko [45]

Answer:

\frac{AC}{DF} = \frac{5}{2}

Step-by-step explanation:

Scalene triangle are the triangle with no side are equal in length also each angle have different measure.

As given there are two scalene triangle, which are similar.

∴ Side of both the triangle will be propotionally equal.

Scale is given for both the triangle, which is 5:2.

We know, scale factor= ratio of the side.

Looking the option provided, we see \frac{AC}{DF} = \frac{5}{2}

As the sides of both the triangle is propotionally equal

Hence, \frac{AC}{DF} = \frac{5}{2}.

1) you can buy 6 candy bars because $5.10 / $0.85 =
6.
To check: 6*0.85=5.10

2) you can find the answer by adding 3 to 12. 3+12=15 n=15 and it said n can be greater than or equal so
N(greater than or equal to sign) 15.
To check: 15-3=12
12=12
16-3>12
13>12

7) x-7=12
+7 +7
X=19
To check: 19-7=12
12=12

8) y/8=7
*8 *8
Y= 56
To check: 56/8=7
7=7

9) 10-4x=6x
+4x +4x
10=10x
/10 /10
X=1
To check: 10-4(1)=6(1)
10-4=6
6=6


Hope this helped!
