Answer:
180
Step-by-step explanation:
8 x 10 = 80
100 + 80 = 180
3×6/8 reduce is 3× 3/4= 3/1×3/4=9/4 or 2 1/4
Answer:
(3m-4/5)2
Final result :
(15m - 4)2

(3m - —)2
5
Step 2 :
Rewriting the whole as an Equivalent Fraction :
2.1 Subtracting a fraction from a whole
Rewrite the whole as a fraction using 5 as the denominator :
3m 3m • 5
3m = —— = ——————
1 5
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
3m • 5 - (4) 15m - 4
———————————— = ———————
5 5
Equation at the end of step 2 :
(15m - 4)

Step 3 :
Final result :
(15m - 4)2

Step-by-step explanation:
Answer:
The fraction of wood used for horizontal support is 
.
Step-by-step explanation:
Assume that the total piece of wood is of length 1.
It is provided that Talia used 
of the piece of wood for the base of he project.
She use 
of the piece of wood for the for the vertical support.
The remaining wood she used for horizontal support.
The amount of wood used for horizontal support can be computed by the subtracting the amount of wood used for base of the project and vertical support form 1.
Compute the amount of wood used for horizontal support as follows:
Thus, the fraction of wood used for horizontal support is .
