Eight bags of chips and four sodas cost $5. Four bags of chips and eight sodas costs
$7. How much does a bag of chips cost? How much does a soda cost?
Answer:
let x be chips and y be sodas
8x + 4y = 5 ---> for the first hint
4x + 8y = 7------> second hint
0.25 cents is how much chips costs
and 0.75 cents is how much sodas costs
Answer: Each bag of chips is $0.25, each soda is $0.75.
(0.25 x 8) + (0.75 x 4) = 5
2 + 3 = 5
(0.25 x 4) + (0.75 x 8) = 7
1 + 6 = 7
4x – 4y = 24
y= 7x + 6
A) (-2, 8)
C) (-8,8)
B) (-2, -8)
D) (-8, -8)
Answer:
B) (-2, -8) is the solution for 4x - 4y = 24 and y = 7x + 6
Step-by-step explanation:
4x - 4y = 24
4(-2) - 4(-8) = 24
-8 - (-32) = 24
-8 + 32 = 24
24 = 24
y = 7x + 6
-8 = 7(-2) + 6
-8 = -14 + 6
-8 = -8

Step-by-step explanation:
for the lines to be parallel, 4x+20 and 6x-10 have to be equal, so you can solve by making it 2x+10 to get 5
Answer:
its the first one to solve future questions like this you can replace the x with the answers till they both have the same number
Jessica started the school year when she was 64.15 inches tall. She grew 2.87 inches during the school year. How tall, in inches, was Jessica at the end of the year? Show your work.
Answer:
67.02 inches
Step-by-step explanation:
If Jessica started out 64.15 inches and grew 2.87 inches then you know that you must add these together.
64.15 + 2.87 = 67.02
Jessica is 67.07 inches at the end of the school year.

Step-by-step explanation:
Each exterior angle of a regular polygon is 9°
Calculate the number of sides of the polygon
Answer:
40
Step-by-step explanation:
The sum of the exterior angles of a polygon = 360°
Divide this by the value of 1 exterior angle to find the number of sides n
n = 360 ÷ 9 = 40
Answer:
Required Answer :-Let the number of sides=x
Each angle measures 9°As we know that in a polygon
[tex]{\boxed{\sf Sum\;of\:exterior\:angles=360°}}[/tex]
Substitute the values[tex]{:}\longrightarrow[/tex][tex]\sf 9x=360 [/tex]
[tex]{:}\longrightarrow[/tex][tex]\sf x={\dfrac {360}{9}}[/tex]
[tex]{:}\longrightarrow[/tex][tex]\sf x=40 [/tex]
[tex]\therefore[/tex]Number of sides=40.
Make x the subject a=bx+c
Answer: [tex]x=\frac{a-c}{b}[/tex]
Step-by-step explanation:
Answer:
x = [tex]\frac{a-c}{b}[/tex]
Step-by-step explanation:
Given
a = bx + c ( subtract c from both sides )
a - c = bx ( isolate x by dividing both sides by b )
[tex]\frac{a-c}{b}[/tex] = x

Maricella solves for x in the equation 4 x minus 2 (3 x minus 4) + 4 = negative x + 3 (x + 1) + 1. She begins by adding –4 + 4 on the left side of the equation and 1 + 1 on the right side of the equation. Which best explains why Maricella’s strategy is incorrect?
The multiplication that takes place while distributing comes before addition and subtraction in order of operations.
In order to combine like terms on one side of the equation, the inverse operation must be used.
When the problem is worked in the correct order, the numbers that Maricella added are not actually like terms.
Maricella did not combine all three constants on both sides of the equation; she combined only two.
Answer:
The multiplication that takes place while distributing comes before addition and subtraction in order of operations.

PLS HELPS ME!!!!!!!!!!!!
Answer:
Step-by-step explanation:
1).
(a). Yes, the graph is linear.
(b). Rate of change is a slope m, m = (60 - 80) / (10 - 0) = - 2
2). Graph is not proportional, because y-intercept is (0, 80) and not (0, 0)

ABCD is a square
=> Δ ABD is a isosceles right triangle at A
using pythago theorem, we have:
AB² + AD² = BD²
=> 2AD² = 4
⇔ AD² = 2
⇒ AD = √2
through O, draw EF parallel to AD and BC
=> EF is diameter
because EF//AD => EF = AD = √2 (because circle O is inscribed the square ABCD)
=> the area of the circle is [tex]S=\frac{(\sqrt{2})^{2} }{4}.\pi =\frac{\pi }{2}[/tex]
