Step-by-step explanation:
The perimeter is the sum of the measures of the 3 sides.
Sum the sides and equate to 75, that is
2x - 9 + 3x + 4 + 2x + 3 = 75, that is
7x - 2 = 75 ( add 2 to both sides )
7x = 77 ( divide both sides by 7 )
x = 11
Thus
AB = 2x - 9 = 2(11) - 9 = 22 - 9 = 13 m
BC = 3x + 4 = 3(11) + 4 = 33 + 4 = 37 m
AC = 2x + 3 = 2(11) + 3 = 22 + 3 = 25 m
Answer:
x=11
Side lengths:
AB=13
AC=25
BC=37
Step-by-step explanation:
We can create an equation based off of the given information. Then, we simplify the equation to solve.
[tex](2x+3)+(3x+4)+(2x-9)=75\\(2x+3x)+(3+4)+(2x-9)=75\\(5x+7)+(2x-9)=75\\(5x+2x)+(7-9)=75\\7x-2=75\\7x=77\\x=11[/tex]
Then, we insert 11 for x, and evaluate the expressions for the side lengths.
[tex]AB=2x-9=2*11-9=22-9=13[/tex]
[tex]AC=2x+3=2*11+3=22+3=25[/tex]
[tex]BC=3x+4=3*11+4=33+4=37[/tex]
Finally, we check.
13+25+37 is 75, so this should be correct.

The number of grams consumed will be; at least 36 and no more than 63.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We have been given that cookie contains 9 grams of fat and eat no fewer than 4 and no more than 7 cookies, then;
Since each cookie has 9 grams of fat, four cookies would be;
4 x 9 = 36 grams of fat.
Also, the nine cookies have 7 x 9 = 63 grams of fat.
Therefore, the number of grams consumed will be; at least 36 and no more than 63.

For Judy's birthday, her friends gave her a gift card. She went to the clothing store and bought a total of $178.25 worth of clothing. Judy used all of the money on the gift card to pay for part of the total. She paid the remaining $71.30 with cash. Which percentage best describes the part of the total Judy paid for with the gift card?
Answers
Answer:
60%
Step-by-step explanation:
Firstly, we want to solve for the amount on the gift card
the total cost is $178.25
the cash payment is $71.30
then the value of the gift card is
=$178.25- $71.30
=$106.95
Therefore the percentage of the gift card to the total pay is
=(106.95/178.25)*100
=0.6*100
=60%

What is a Ratio?A ratio shows us the number of times a number contains another number.
Since For every 5 hardcover books a teacher buys, he or she can get 2 paperback books for free. Therefore, the ratio of hardcover books to paperback books will be,
Hardcover/paperback = 5/2
Using the same ratio for 35 hardcover books,
35/Paperbook = 5/2
(35×2)/5 =Paperbook
Paperbook = 14
Hence, the number of paperback books Ms. Baldwin get for free is 14.

A family daycare center charges a $75 enrollment fee and $100 per week for a child to attend. Write the linear equation to model this situation.
Answers
Answer:
100x+75=y
Step-by-step explanation:
Answer:
y=100x+75. Where y equals total cost and x equals numbers of weeks enrolled.
Step-by-step explanation:
75 is the upfront cost, aka the cost of zero weeks, this cost will never change and is a one-time payment, therefore it needs no variable. 100 is the cost per week which means every week costs 100 more dollars, this is why it must have a variable because it will change with time. They are added together because they both show the total cost and together will show how much one person is spending.
