Answer:
She bought 24 Tangram puzzles
Step-by-step explanation:
Let the number of Tangram puzzles be t and the number of IQ puzzles be i
The sum of all the puzzles is 40;
i + t = 40 ••••••(i)
Cost of all Tangram puzzles at a cost of $4 per one will be;
4 * t = $4t
cost of all Iq puzzles at a cost of $2 per one is
2 * i = $2i
Sum
paid for all is $128
so;
4t + 2i = 128 •••••••(ii)
From equation i;
i = 40-t
Substitute into ii
4t + 2(40-t) = 128
4t + 80 - 2t = 128
2t = 128-80
2t = 48
t = 48/2
t = 24

2(length + width). What is the perimeter, in units, of a rectangle of length fraction 1 over 3 unit and width fraction 1 over 2 unit?
Answer:
1 and 2/3
Step-by-step explanation:
If
length = 1/3 and width= 1/2
then the equation will look like this,
2(1/3+1/2)
1/3+1/2= 5/6
2(5/6)= 1 and 2/3
Tickets at an amusement park are $25 for children and $45 for adults. If the Jones family has $200 cash and they have two children, what is the maximum amount of adult tickets they can purchase?
Answer:
3
Step-by-step explanation:
25+25= 50 spent on the kids, leaving 150 to spend on the adults, 45 can go into 150 3 times.
hope this helps!!!
Answer:
3 maximum adult tickets
Step-by-step explanation:
children's ticket = $25
adult's ticket = $45
total amount of money $200
let x be the number of adults:
45x + 2(25) = 200
45x + 50 = 200
45x + 50 - 50 = 200 - 50
45x = 150
[tex]\frac{45x}{45} = \frac{150}{45}[/tex]
x = 3
to check:
2 children x $25 each = $50 in total
4 adults x $45 adults = $135 in total
⇒ $200 - ($135 + $50)
⇒ $200 - $185
⇒ $15 remaining

can somebody please help me with this, please make sure the answer is correct I need this assignment in and I need to get a good grade on it if I want to have a c on my report card, currently I have an F so yeah
Answer:
41
Step-by-step explanation:
Hey There!
So to solve this problem the first thing that we want to do is solve for x
angle P and angle S are supplementary angles meaning that they will add up to equal 180
so 180=8x+3+2x+7
step 1 combine like terms
8x+2x=10x
3+7=10
now we have
180=10x+10
step 2 subtract each side by 10
180-10=170
10-10 cancels out
now we have
170=10x
step 3 divide each side by 10
10/10 cancels out
170/10=17
so x=17
So remember in parallelograms opposite angles are congruent so angle Q is congruent with angle S
so we just plug in 17 into 2x+7 and we will get the value of angle Q
17x2=34
34+7=41
so angle Q = 41
The money Sky makes from babysitting is directly proportional. After 4 hours, she makes $72. How much money would she make after 7 hours?
A) $72
B) $52
C) &126
D) $108
Answer:
C. $126
Step-by-step explanation:
Let us say x is the amount of money Sky makes for babysitting 7 hours.
[tex]\frac{72}{4} =\frac{x}{7}[/tex]
[tex]\frac{72}{4} = 18[/tex]
[tex]18=\frac{x}{7}[/tex]
x=$126

Answer:
3. B
4. D
Step-by-step explanation:

4.Substitute the values and check
Answer and Step-by-step explanation:

Before we look at the answer choices, lets analyze the graph.
We see that as the graph goes right, the y values are positive, and that as the graph goes left, the y values become negative/decrease. (Graph, as in the line on the graph).
That means the graph has a positive slope. So we can get rid of any negative slopes (answer choices A and C).
Now, we look to see the rate of change of the graph. How many units does the graph go up and right right?
We see that the graph has a rate of change of 2, so that is the slope.
This means that answer choice B is the answer. The equation shows that it goes down 4 units as well, which is what the graph shows as well.
4.
For this one, we need to see the pattern in the table.
When we put 2 in for n, we get 6. When we put 3 in for n, we get 8. And when we put 4 in for n, we get 10.
Answer choice D works for this. If we plug 2, 3, and 4 in for this expression, we get:
2(2) + 2 = 4 + 2 = 6
2(3) + 2 = 6 + 2 = 8
2(4) + 2 = 8 + 2 = 10
So answer choice D is the answer.

$750 at 6% for 18 months
Answer:
ecall that 6 + 6 + 6 = 6 × 3
Instead of adding 6 three times, you can multiply 6 by 3 and get 18, the same answer.
Similarly,
6 + 6 + 6 + 6 + 6 + 6 + 6 = 6 × 7 = 42
Still by the same token,
2 + 2 + 2 + 2 = 2 × 4
