Answer:
[tex]2.5p + 4m \leq 30[/tex]
Step-by-step explanation:
Given
Poster = $2.50
Magnet = $4.00
Amount = Up to $30
Required
Determine the inequality
Represent posters with p;
This implies that she can buy 2.50p worth of posters
Represent magnets with m
This implies that she can buy upto 4m worth of magnets
The question says she can spent up to $30;
This implies that she can spend at most $30 and this can be mathematically represented as [tex]\leq 30[/tex]
Bringing the parameters together; we have
[tex]2.5p + 4m \leq 30[/tex]
The system of inequalities that represents the situation is [tex]2.5x+4y\leq 30[/tex] and this can be determined by using the given data and arithmetic operations.
Given :
A postcard book costs $2.50 and a magnet costs $4.00.Shandra can spend up to $30 all together.Let the total number of postcards be 'x' and the total number of magnets be 'y'. The following steps can be used to determine the inequalities that represent the situation:
Step 1 - Multiply 2.5 with x.
2.5x
Step 2 - Multiply 4 with y.
4y
Step 3 - Now, add the above two expressions.
2.5x + 4y
Step 4 - Now, apply the inequality.
[tex]2.5x+4y\leq 30[/tex]
The system of inequalities that represents the situation is [tex]2.5x+4y\leq 30[/tex].

A T-shirt shop charges $15 for an adult shirt and $12 for a youth shirt. The total charge for a shirt order was $489.
Which equation can be used to represent x, the number of adult shirts sold and y, the number of youth shirts sold?
12x + 15y = 489
27x + 15y = 489
15x + 12y = 489
15x + 3y = 489
Answer: C. 15x + 12y = 489
Step-by-step explanation: Got it right on edge test
Answer:
C
Step-by-step explanation:
15x+12y=489
Given: g(x) = 3x² + 2 and h(x) = 2x + 2
Find: g(h(x))
Step-by-step explanation:
g(x) = 3x² + 2
h(x) = 2x + 2
g(h(x)) = g([2x + 2]) = 3[2x+2]² + 2
= 3[4x² + 8x + 4] + 2
= 12x² + 24x + 12 + 2
= 12x²+ 24x + 14

Answer:
6
——
x+8
Step-by-step explanation:
The quotient of six (6) and the sum of a number and eight (8) is equal to [tex]\frac{x + 8}{6}[/tex]
Let the unknown number be x.
In Mathematics, quotient simply means to divide a number by another number without any remainder.
Translating the word problem into an algebraic expression, we have;
The sum of a number and eight = [tex]x + 8[/tex]
Quotient of six (6) and the sum of a number and eight (8) is equal to;
[tex]\frac{x + 8}{6}[/tex]
In conclusion, the quotient of six (6) and the sum of a number and eight (8) is equal to [tex]\frac{x + 8}{6}[/tex]

A can do a work in 14 days and working together A and B can do the same work in 10 days. In what time can B alone do the work? (i dont get this one, please explain :)
Answer:
35 days
Step-by-step explanation:
A = 14 days
It means per day, work done by A= 1 / 14
A+B = 10 days
Work done by A and B per day = 1 / 10
In what time can B alone do the work?
To solve this, we have
A+B = A alone + B alone
1/10 = 1/14 + B alone
Subtract 1/14 from both sides
1/10 - 1/14 = 1/14 + B alone - 1/14
14-10/140 = B alone
4/140 = B alone
B alone= 1 / 35
Work done of B alone = 1/35
B alone will do the work in 35 days
Answer:
35 days.
Step-by-step explanation:
A can do the work in 14 days: per day work done by A=1/14
A and B can do the work in 10 days: per day work done by A and B=1/10
Work is done by B per day=1/10–1/14=7/70-5/70=(7–5)/70=2/70=1/35.
So, B takes 35 days.

Find the midpoint of the line segment joining the two points.
(1.8, -3.4) and (-0.4, 1.4)
Answer:
(0.7, -1)
Step-by-step explanation:
To find the coordinates for the midpoint you add each coordinate together and divide by 2.
M = ([tex]\frac{1.8 - 0.4}{2}, \frac{-3.4 + 1.4}{2}[/tex])
M = [tex](\frac{1.4}{2}, \frac{-2}{2})[/tex]
M = (0.7, -1)

how to do this question plz
Answer:
The answer is yes.
Step-by-step explanation:
All you have to do is substitute the y, which is 5, and the x, which is 2, into the equation. When you solve it the answer in the end will be 5=5, which means that point (2,5) does line on that line.

Duval scored 10 more than 2 times the number of points scored by a
player, x. Which equation shows the number of points, y, Duval scored?
Answer:
2x + 10 = y
Step-by-step explanation:
The term 10 more is plus 10, and 2 times the "number" which we know we can label as "x". 2x + 10 is the equation and we are told that y is the number of points so 2x + 10 = y is the answer.
Hope that helps, and have a great day!
Ms. G, Mr. Adams, and Ms. Leahman are going for a bike ride together on Saturday. They want to meet each other in the city but they all live in Bedstuy. Ms. G and Ms. Leahman have to bike 4 miles there, Mr. Adams is 5 miles away. They meet each other in the city and bike 2 miles together. Then they all return home the same way. How many miles did they all bike in total on Saturday?
Answer: 22 miles
Step-by-step explanation: Ms. G and Ms. Leahman both bike the same amount on Saturday:
4 miles to go to the city;
2 miles with Mr. Adams;
4 miles back to Bedstuy;
Then, both biked:
4 + 2 + 4 = 10 miles
Now, Mr. Adams bikes:
5 miles to go to the city;
2 miles together with the other two;
5 miles back to Bedstuy;
Then, he biked, in total:
5 + 2 + 5 = 12miles
So, the three of them biked, in total:
10 + 12 = 22
On Saturday, Ms. G, Mr. Adams and Ms. Leahman biked, in total, 22 miles.

We can see that the diagonal distance from the fire pit to the tree is 6 units, if you count, with a slope of 1, meaning that we only have to stay on that diagonal.
A third of 6 is 2, so we'll just go 2 units in that diagonal, putting us at the point [tex](4,3)[/tex].
