Answer:
Streamers cost 2.50 and balloons cost 1.25.
Step-by-step explanation:
Pls mark brainliest.
Answer:
Balloon : $1.25
Streamer : $ 2.50
Step-by-step explanation:
Form simultaneous equations.
Let streamer be represented by ------------s
Let balloons be represented by ------------b
So the equations will be;
3s + 2b = 10 ----------------i
2s + 1b = 6.25---------------ii
Make the terms with s equal by multiplication
[3s + 2b = 10 ]2
[2s + 1b = 6.25]3
Perform subtraction
6s + 4b = 20
6s + 3b = 18.75
b = 1.25 ---------iii
Use iii in ii as;
2s + 1b = 6.25
2s + 1.25 = 6.25
2s = 6.25 - 1.25
2s = 5.00
s= 5.00 / 2
s= 2.5
Hence ; a balloon is $1.25 and a streamer is $2.5

Answer:
they are parallel
Step-by-step explanation;
You would have to get the Y by itself in the bottom one so go
2x-3y=-3
-2x -2x
-3y=2x-3
_________
-3 -3
_________
y= -2/3x+ 1
and they are the same equaion
so they end up parallel

Answer:
1) $68.40
2)456 tickets
Step-by-step explanation:
1)
They need to raise $8,250.
They have already raised $3,120.
The amount they have still to raise is $8,250-$3,120=$5,130.
There are 75 band members, so the amount yet to raise per member is $5,130/75=$68.40.
2)
The businesses give $0.50 for every $1 in ticket sales, ie. they pay an extra 50% of the total.
Let number of tickets sold=x
Let money made from ticket sales = 7.5x
The total amount of money made is therefore 1.5(7.5x)=11.25x
The minimum amount of tickets to hit $5,130:
$5,130=11.25x
x=456
could you help me understand cross sections of three-dimenstional object its harder than it sound.
A section, or cross-section, is a view of a 3-dimensional object from the position of a plane through the object. A section is a common method of depicting the internal arrangement of a 3-dimensional object in two dimensions. It is often used in technical drawing and is traditionally crosshatched.
Cross sections of three-dimensional objects are two-dimensional shapes of various sizes. They may be parallel to a side or base of the object or at an angle to these surfaces. A cross section may resemble the shape of the object’s side or base, or it may have a completely different shape.

The number of transistors per IC in 1972 seems to be about 4,000 (a rough estimate by eye). Using this estimate and Moore's Law, what would you predict the number of transistors per IC to be 20 years later, in 1992?
From the Moore's Law, the predicted number of transistors per IC in 1992 would be approximately 4,096,000.
Given data:
Based on this exponential growth pattern, use the estimate of 4,000 transistors per IC in 1972 to predict the number of transistors per IC in 1992.
To predict the number of transistors per IC in 1992, determine how many doublings occurred during the 20-year period from 1972 to 1992.
Since each doubling represents a multiplication by 2, calculate the number of doublings as follows:
Number of doublings = (1992 - 1972) / 2
Number of doublings = 20 / 2
Number of doublings = 10
Now, use this number of doublings to predict the number of transistors per IC in 1992:
Predicted number of transistors per IC in 1992 = 4,000 * (2^10)
Predicted number of transistors per IC in 1992 = 4,000 * 1,024
Predicted number of transistors per IC in 1992 ≈ 4,096,000
Hence, based on Moore's Law and the estimate of 4,000 transistors per IC in 1972, the predicted number of transistors per IC in 1992 would be approximately 4,096,000.

2^6 x 5^2
Answer:
108 x 25² divided by 2⁶ x 5² is equal to [tex]42\frac{3}{16}[/tex]
Step-by-step explanation:
Given;
108 x 25² divided by 2⁶ x 5²
The expression is simplified as follows;
[tex]\frac{108\times 25^2}{2^6 \times 5^2} = \frac{108\times 625}{64\times25} =\frac{675}{16} = 42\frac{3}{16}[/tex]
Therefore, 108 x 25² divided by 2⁶ x 5² is equal to [tex]42\frac{3}{16}[/tex]

Solve the system by substitution.
y = x - 8
y = 2x - 14
The solution is (_, _).
Answer:
x= 6
y= -2
Step-by-step explanation:
y = x-8........equation 1
y= 2x-14.......equation 2
Substitute x-8 for y in equation 2
x-8= 2x-14
x-2x= -14+8
-x= -6
x= 6
Substitute 6 for x in equation 1
y= x-8
y= 6-8
y= -2
Hence x = 6 and y is -2

Enter an equation in point-slope form for the line.
Slope is 8 and (-7, -1) is on the line.
The equation of the line in point slope form is:
Answer:
y + 1 = 8 (x + 7)
Step-by-step explanation:
point slope form is
y - y1 = m (x - x1)
So replace the y1 with the y point, and the x1 with the x point
y - (-1) = m (x - (-7) )
then replace the m with the slope
y - (-1) = 8 (x - (-7) )
now solve
y + 1 = 8 (x + 7)

Find the unit rates. 4 ounces for $5.89
Answer:
Around $1.47
Step-by-step explanation:
To find the unit rate you need to have a denominator of one. (5.89/4 = x/1)
All you have to do is divide 5.89 by 4 and you get 1.4725 and if you round that to the nearest 100th place you get 1.47.
So 1 once cost $1.47
