Answer:
around 90 cm because that measure is equal to 180 you divide into 2 so the answer is 90
Answer:
The inequality to represent this scenario is given as:
7x + 12y ≥ 200
Step-by-step explanation:
From the question:
Daniella has two jobs. She earns $7 per hour babysitting her neighbor's children and she earns $12 per hour working at the coffee shop.
Let:
The number of hours babysitting = (x) The number of hours working at the coffee shop= (y)
We are told in the question that:
Daniella will need to work to earn at least $200.
At least means equal to or greater than
Hence,
The inequality to represent this scenario is given as:
$7 × x + $12 × y ≥ $200
7x + 12y ≥ 200
Let E represent English test and M represent Math test.
M + E = 164
+ <u>M - E = 22</u>
2M = 186 <em>eliminated E by adding the two equations</em>
M = 93 <em>divided both sides by 2</em>
Now, plug that value into either of the equations to solve for E.
M - E = 22 → 93 - E = 22 → -E = 22 - 93 → -E = -71 → E = 71
Answer: Math = 93, English = 71
Answer:
John has $21.
Step-by-step explanation:
Let John's "wealth" be w. Then 2w+8 = 50, or 2w = 42, or w = 21.
John has $21. Eight more than twice this is 42+8 = 50, as expected.
