Answer:
The sum of all the possible values for z that satisfy the above equation is -5.
Step-by-step explanation:
The given equation is
We need to find the sum of all the possible values for z that satisfy the above equation.
The given equation can be rewritten as
Cancel out common factors.
Add 2 on both sides.
Multiply both sides by -1.
Only z=-5 satisfy the given equation.
Therefore the sum of all the possible values for z that satisfy the above equation is -5.
The same constant value(s)
Answer:
19.53
Step-by-step explanation:
First let's find the new price of the backpack:
40% of 29.99 is
29.99 * 0.40 = 11.99
So the new price of the backpack is
29.99 - 11.99 = 18.00
Now let's find the price with tax
8.5% of 18.00 is
18.00 * 0.085 = 1.53
So the cost of the backpack is
18.00 + 1.53 = $19.53
Step-by-step explanation:
according to the given question
there are 10 bags each have 15kg potatoes so basically, we have 150 kg of poatoes
i want these potatoes to be equally distributed in 50 bags
therefore, mass of potato in 1 bag = total kg's of potatoes÷nuber of bags
mass of potato in 1 bag=150÷50 equals 3 kg
and so, each bag will have mass 3 kg
Answer:
x = 7
Step-by-step explanation:
*set equations = to each other since they're corresponding angles which are equal to each other*
15x - 5 = 13x + 9 --> *subtract 13x from both sides*
2x - 5 = 9 --> *add 5 to both sides*
2x = 14 *divde by 2 on both sides*
x = 7
check:
15 (7) - 5 = 13 (7) + 9
105 - 5 = 91 + 9
100 = 100
