seven hamburgers and four sodas cost $27.35. Four hamburgers and five sodas cost $18.75
I need to find the equation of each sentence.
WILL MARK BRAINLIEST (or however you spell it)
Answer:
equations:
7x + 4y = 27.35
4x + 5y = 18.75
Step-by-step explanation:
x = burgers
y = sodas
---------------------------------
7x + 4y = 27.35
4x + 5y = 18.75

5m − (m + 4) = 2?
f. -1/2
g. 1/2
h. 1
j. 3/2
k. 3
Answer:
J. 3/2
Step-by-step explanation:
Let's solve your equation step-by-step.
5m−(m+4)=2
Step 1: Simplify both sides of the equation.
5m−(m+4)=2
5m+−1(m+4)=2(Distribute the Negative Sign)
5m+−1m+(−1)(4)=2
5m+−m+−4=2
(5m+−m)+(−4)=2(Combine Like Terms)
4m+−4=2
4m−4=2
How many free throws could you make out of 20
Awnser :
Ten
Explanation :
In a relaxed practice setting with no pressure, the average player should be able to make at least ten in a row. But free throws typically come in pressure situations, so managing the pressure is as important as practicing form.
Write the equation of the line that is parallel to the line y= -2x+3 and goes through the point (3, -6).
Answer:
y=-2
Step-by-step explanation:
because it's parallel --> a=-2
therefore we have y=-2x+b
the line goes through the point (3,-6) --> (-2).3+b=-6 --> b=0

Angle ADO = 48°
Work out the size of angle ABD.
(4 marks)
please help asap ill give brainliest
Answer:
∠ ABD = 42°
Step-by-step explanation:
∠ ODC = 90° ( angle between tangent and radius )
∠ ADC = 90° - 48° = 42°
The angle between a tangent and a chord is equal to the angle in the alternate segment, that is
∠ ABD = ∠ ADC = 42°

Answer:
2167.7 sq yds
Step-by-step explanation:
SA(cone) = πr² + πrs ('s' = slant height)
= π(15)² + π(15)(31)
= 225π + 465π
= 690π
= 2167.7
I need help with this
Answer:
We add up all the numbers:
84 + 72 + 96 + 97 + 75 + 83 + 81 = 588
Since there are 7 numbers we divide by 7
588 divided by 7 = 84 is your mean
Step-by-step explanation:
How to find mean:
Add up the numbers, divide by the many numbers there are and thats how you find your mean.

Write the equation of the line in fully simplified slope-intercept form.
Answer:
[tex]y=-\frac{1}{4} x-6[/tex]
Step-by-step explanation:
The slope-intercept form is [tex]y=mx+c[/tex], where m is the slope of the line and c is where the line crosses the [tex]y[/tex]-axis.
To calculate [tex]m[/tex] we can use the formula [tex]m = \frac{dy}{dx}[/tex] where [tex]dy[/tex] is the difference in [tex]y[/tex] between two points and [tex]dx[/tex] is the difference between [tex]x[/tex].
Information we can get from the graph given: [tex]c=-6[/tex]. Since [tex]c[/tex] is the point at which the line crosses the [tex]y[/tex]-axis.
To find [tex]m[/tex] let's get two points from the graph.
Point 1: [tex](4,-7)[/tex]
Point 2: [tex](8,-8)[/tex]
Now use the equation [tex]m = \frac{dy}{dx}[/tex].
[tex]m = \frac{-7 - (-8)}{4-8} = -\frac{1}{4}[/tex].
Now we have [tex]m[/tex] and [tex]c[/tex], let's put them back into the general equation.
[tex]y=-\frac{1}{4} x-6[/tex]

find the area of a semi circle with radius 12cm give your answer in terms of pi
Answer:
72pi
Step-by-step explanation:
The formula for the area of a circle is pi*r^2
Since three radius is 12, then it’s pi*12^2
pi*12^2= 144 x pi but that’s the area of a whole circle so divide by 2 and you get:
72pi
Answer:
226.195 cm²
In terms of pi:
A = (π · 12²) ÷ 2
Step-by-step explanation:
A = πr²
A = π · 12²
A = π · 144
A = 452.39
452.39 ÷ 2

Harper is getting a new rug in her bedroom. Her bedroom is in the shape of a rectangle with a length of 9 feet and a width of 14 feet. If the rug cost $1.75 per square foot, how much will it cost to purchase the rug?
Answer:
D) 220.50
Step-by-step explanation:
9x14 = (9x9)+(9x5) =126 126 x 1.75 (.75x126) + 126 = 220.50
AKA: 9x14 = 126 126 x 1.75 = 220.50
