Solution:
The expression "a(b-c)" is an example of distributive property. To simplify it, simply multiply a by the terms inside the bracket.
<u>Simplifying the distributive property.</u>
- => a(b - c)
- => (a x b) + (a x -c)
- => ab - ac
Hence, the simplified expression is ab - ac.
Step-by-step explanation:
since all angles add up to 180:
(8x-1)+(3x+4)+(3x+9)=180
add like terms:
14x+12=180
x=12

The ratio 2:11 means for every 3 apple trees they will plant 11 pear trees.
They are planting 150 apple trees. Divide total apple trees by the ratio: 150/3 = 50
Multiply that by the ratio of pear trees:
50 x 11 = 550
They need to plant 550 pear trees.
Answer:
s = 10
Step-by-step explanation:
Given s is inversely proportional to t , then the equation relating them is
s =
← k is the constant of proportion
To find k use the condition when s = 0.6, t = 5
0.6 =
( multiply both sides by 5 )
3 = k
s =
← equation of proportion
When t = 0.3, then
s =
= 10
