Answer:
-1 1/5
Step-by-step explanation:
<em>Change the whole number 4 to an improper fraction</em>
-4 4/5 ÷ 4/1 = -4 4/5 ÷ 4/1
<em>Reciprocal the 4/1 will become 1/4 then go to multiplication</em>
-4 4/5 ÷ 4/1 = -4 4/5 × 1/4
<em>Change to improper fraction the -4 4/5</em>
-4 4/5 ÷ 4/1 = -24/5 × 1/4
<em>Then simply multiply the two numerators and the two denominators</em>
-4 4/5 ÷ 4/1 = -24/20
<em>Finally, Simplify it to get the answer</em>
-4 4/5 ÷ 4/1 = -1 1/5
Answer:
p + q = 20
Step-by-step explanation:
Given the lines intersect at (1, 1 ) then x = 1 and y = 1 make the equations true.
Consider
px = 12 with x = 1
p = 12
Consider
2x + qy with x = 1 and y = 1
2 + q = 10 ( subtract 2 from both sides )
q = 8
Hence p + q = 12 + 8 = 20
Answer:
x=25
Step-by-step explanation:
25*25=625 therefore x= 25
Answer:
Step-by-step explanation:
<u>Sum of 8 fifths and 4:</u>
- 8/5 + 4 =
- 1 3/5 + 4 =
- 5 3/5
<u>7 copies of the of sum of 8 fifths and 4:</u>
- 7 × 5 3/5 =
- 7( 5 + 3/5) =
- 35 + 7(3/5) =
- 35 + 21/5 =
- 35 + 4 1/5 =
- 39 1/5 or 39.2
(3a²+6ab-24²)= 3a(a+2b)x(4b)
