Answer:
d. $28.70
Step-by-step explanation:
first you divide 126 by 9 and you get 14 then you times 14 by 2.05 and you come out with a total 28.70
His is:-
250 - 2/5 *250 - 3/10 * 250
= 250 - 100 - 75
= 250 - 175
= 75 answer
Answer:
1st option
Step-by-step explanation:
7x + 7 and 112 are vertically opposite angles and are congruent , then
7x + 7 = 112 ( subtract 7 from both sides )
7x = 105 ( divide both sides by 7 )
x = 15
4y and 112 are adjacent angles and sum to 180° , that is
4y + 112 = 180 ( subtract 112 from both sides )
4y = 68 ( divide both sides by 4 )
y = 17
Answer:
85 + z <= x <= 255 + z
Step-by-step explanation:
An inequality system will be given by a lower limit and an upper limit, therefore it is only necessary to raise an equation for each case, h being the hours worked and z the extra money you can earn by delivering the pizzas:
For the lower limit:
8.5 * h + z, knowing that in this case it is 10 hours.
85 + z would be the lower limit value
For the upper limit:
8.5 * h + z, knowing that in this case it is 30 hours.
225 + z would be the upper limit value
Therefore the inequality system would be as follows, let x be the money earned:
85 + z <= x <= 255 + z
Which means that the money earned will be determined by the previous inequality.
