Answer:
Number of sent mail = 36
Number of received mail = 75
Step-by-step explanation:
Let,
x be the number of mails sent
y be the number of mails received
According to given statement;
x + y = 111 Eqn 1
y = 2x + 3 Eqn 2
Putting value of y from Eqn 2 in Eqn 1
x + 2x + 3 = 111
3x = 111 - 3
3x = 108
Dividing both sides by 3
[tex]\frac{3x}{3}=\frac{108}{3}\\x = 36[/tex]
Putting x = 36 in Eqn 2
y = 2(36) + 3
y = 72 + 3 = 75
Hence,
Number of sent mail = 36
Number of received mail = 75

angle D=(7b+1) angle E=(2b+1) and angle F=(b+8) what is the measure of angle E
angleD=(7b+1)angle E=(2b+1)and angle F=(b+8)
Answer:
<E = 35
Step-by-step explanation:
7b + 1 + 2b + 1 + b + 8 = 180
combine like terms
7 + 2 + 1 = 10
10b
1 + 1 + 8 = 10
10b + 10 = 180
substract 10 from 180
= 170
10b = 170
170 divided by 10
= 17
now plug in for b for angle E
2 (17) + 1
= 35
A recipe calls for 1/2 cup of milk for every 3/4 cups of flour. How much milk is required for every cup of flour. *
Answer:
2/3rds
Step-by-step explanation:
for 1 cup of flour you multiply 3/4th by 4 then devide by 3 giving you one cup of flour, now to keep it balanced you do the same to the milk, thus multiplying 1/2 by 4 then dividing it by three, which is 2, you then divide 2 by 3 giving you yours answer, 2/3rds
Answer:
A recipe calls for 1/2 cup of milk for every 3/4 cups of flour. How much milk is required for every cup of flour. *
Step-by-step explanation:
So for every 1/2 a cup is 3/4 cups of flour so if you need to know how much cups of flour is used for 1 total cup of milk you have to add you multiply it is optional if you add put the two fractions next to each other you need to add to the side witch the numbers are 3 so 3+3 is 6 so you got the answer just put the number 4 under the 6 and it will be 6/4 or you could say 1 2/4 or 1 1/2 .
8 (5 + 4n) + 11 = -5 (3 - 7n)
Answer:
n=1
Step-by-step explanation:
(5 + 4n) + 11 = -5 (3 - 7n)
5+4n+11=−5(3−7n)
simplify
4n+16=−5(3−7n)
expand
4n+16=−15+35n
regroup
4n+16=35n−15
subtract
16=35n−15−4n
simplify
16=31n−15
add
16+15=31n
simplify
31=31n
n=1
Hope this helps :)
(pls mark brainliest)
Answer:
n=22
Step-by-step explanation:
8 (5 + 4n) + 11 = -5 (3 - 7n)
distribute
=> 40+32n+11=-15+45n
add like terms
=> 51+32n=-15+35n
subtract 35n on both sides and subtract 51 on both sides
32n-35n=-15-51
add like terms
-3n=-66
divide both sides by -3
n=22

y=x+2
3x+3y=6
Answer:
(0,2)
x=0
y=2
Step-by-step explanation:
We know that y=x+2
This means that we can subsitute this for y into the second equation
3x+3(x+2)=6
This is easy to solve
3x+3x+6=6
6x=0
x=0
We can then use this value for x in the second equation
y=0+2
y=2
I doubled checked this answer on desmos and my math is correct
Answer:
Answer:
(0,2)
x=0
y=2
Step-by-step explanation:
We know that y=x+2
This means that we can subsitute this for y into the second equation
3x+3(x+2)=6
This is easy to solve
Step 1:
3x + 3x + 6 = 6
Step 2:
6x=0
6 6
x=0
Then you should substitute y =x + 2 with the given solution from the first equation, x = 0
y=0 + 2
y=2
Your answer should be, x =0 and y = 2 or (0,2)

5.02 Which equation does the graph below represents?
1. y = -1/2x
2. y = -2x
3. y = 1/2x
4. y = 2x
Answer:
2. y= -2x
Step-by-step explanation:
When the line is on an exact point like it is on (-4, 8), we can simplify it by going rise/run
Rise is the same as y (8), and your run is x (-4)
When you divide 8/-4, your answer will be -2
Therefore, the answer is y= -2x

The sum of three consecutive even integers is 486. Find all three integers.
Answer:
161 + 162 + 163 = 486
Step-by-step explanation:
(X) + (X + 1) + (X + 2) = 486
X + X + 1 + X + 2 = 486
3X + 3 = 486
3X + 3 - 3 = 486 - 3
3X = 483
3X/3 = 483/3
X = 161
if a sphere has the same volume as a cube with edge length 5, estimate the radius of the sphere
Answer:
The radius of the sphere will be:
[tex]r=3.1[/tex] unitsStep-by-step explanation:
Given that a sphere has the same volume as a cube with edge length 5.
[tex]V_c=V_s[/tex]
[tex]\:a^3=\frac{4}{3}\pi r^3[/tex]
[tex]\:r^3=\frac{3\:a^3}{4\pi }[/tex]

Find the radius of a circle in which an inscribed square has a side of 8 inches.
Answer:
[tex]4\sqrt{2} =5.66[/tex]
Step-by-step explanation:
The square is in the circle, so the diameter is the diagonal line of the square. This divides the square into two right triangles.
Two sides of the right triangle equal 8. This qualifies it as a special right triangle. This triangle has two sides that = x (in this case 8) and the hypotenuse is [tex]x\sqrt{2}[/tex].
Substitute 8 in for x.
[tex]8\sqrt{2}[/tex] is the diameter, so we divide in half to get the radius = [tex]4\sqrt{2}[/tex]
