Step-by-step explanation:
With Dogs only: 15 - (5+4) = 6
With Cats only: 12 - (5+2) = 5
With Birds only: 8 - (4+2) = 2
With dogs and cats: 5
With birds and dogs: 4
With cats and birds: 2
With dogs, cats, and birds : 0
Total students surveyed: 35
6 + 5 + 2 +5 + 4 + 2 = 24 students with pets
35 - 24 = 11 students have no pets
Answer:
The answer is only 6 have dogs
Step-by-step explanation:
B + C + D - B∩C - B∩D - C∩D + B∩C∩D + x = 35
8 + 12 + 15 - 2 - 4 - 5 + 0 + x = 35
With Dogs only: 15 - (5+4) = 6
Just in case, we can calculate the others too:
With Cats only: 12 - (5+2) = 5
With Birds only: 8 - (4+2) = 2
With dogs and cats: 5
With birds and dogs: 4
With cats and birds: 2
With dogs, cats, and birds : 0
Total students surveyed: 35
6 + 5 + 2 + 5 + 4 + 2 = 24 students with pets
35 - 24 = 11 students have no pets
5(1+s)=9s+6
----------------
Answer:
Solution given
5(1+s)=9s+6
distribute
5+5s=9s+6
subtract both side by 5s
5+5s-5s=9s-5s+6
solve like terms
5=4s+6
subtract both side by 6
5-6=4s+6-6
-1=4s
divide both side by 4
-1/4=s
Answer:
[tex]s=-\frac{1}{4}[/tex]
[tex]s=-0.25[/tex]
Step-by-step explanation:
[tex]5\left(1+s\right)=9s+6[/tex]
Apply distributive law:-
[tex]5\left(1+s\right)[/tex]
[tex]=5+5s[/tex]
[tex]5+5s=9s+6[/tex]
Now, Subtract 5 from both sides :-
[tex]5+5s-5=9s+6-5[/tex]
[tex]5s=9s+1[/tex]
Subtract 9s from both sides:-
[tex]5s-9s=9s+1-9s[/tex]
[tex]-4s=1[/tex]
Divide both sides by -4:-
[tex]\frac{-4s}{-4}=\frac{1}{-4}[/tex]
[tex]s=-\frac{1}{4}[/tex]

Kristy’s cellphone company charges a monthly rate of $45 plus $0.05 per text message sent, and $0.58 per video messages sent. Kristy’s sent 8 video messages in October and receive a bill for $55.29. How many text messages did she sent?
Answer:
About 113.
Step-by-step explanation:
45 + 0.05t +0.58v = 55.29
v = 8
t is 113 text messages.
Kristy’s sent About 113 text messages..
What does it mean to solve an equation?An equation represents equality of two or more mathematical expression.
When someone asks you to solve an equation, then they usually mean to find the values of the unknowns for which that equation would be true (the equality between expressions should hold true for those values).
Solutions to an equation are those values of the variables involved in that equation for which the equation is true.
It is given that Kristy’s cellphone company charges a monthly rate of $45 plus $0.05 per text message sent and $0.58 per video messages sent.
Also Kristy’s sent 8 video messages in October and receive a bill for $55.29.
The equation form as;
45 + 0.05t +0.58v = 55.29
Solve for t when v = 8;
45 + 0.05t +0.58(8) = 55.29
t = 113
Therefore, she sent 113 text messages.

The greater of two numbers is 6 more than 4 times the smaller. Their sum is 41. FInd the numbers.
Answer:
7 and 34
Step-by-step explanation:
let x and y be the 2 numbers with x > y
The 2 equations to solve are
x = 4y + 6 → (1)
x + y = 41 → (2)
Substitute x = 4y + 6 into (2)
4y + 6 + y = 41 , that is
5y + 6 = 41 ( subtract 6 from both sides )
5y = 35 ( divide both sides by 5 )
y = 7
Substitute y = 7 into (1)
x = 4(7) + 6 = 28 + 6 = 34
The 2 numbers are 7 and 34

6x - 6 = 54
Step-by-step explanation:
The hypotenuse of both triangles are 63 and 6x - 6; the second longest sides are 49 (greater than 35) and 42 (greater than 30).
So our proportion:
63/(6x-6) = 49/42
Cross multiply
63*42 = 49*(6x-6)
2646 = 294x-294
2940 = 294x
x = 10
Double-check:
63/(6*10 - 6) = 49/42
63/(60 - 6) = 49/42
63/54 = 49/42
7/6 = 7/6
6x - 6 = 6(10) - 6 = 60 - 6 = 54

Answer:
7.2
Step-by-step explanation:
The points shown form a right angle triangle along the x axis so the distance is the hypotenuse. So
a**2 + b**2 = c**2
4**2 + 6**2 = c**2
16 + 36 = c**2
52 = c**2
52**(1/2) = c

what is 2.3 ÷ 225.4
Answer: 2.3/225.4=0.01020408
Answer:
98.000
Step-by-step explanation:
Change the divisor 2.3 to a whole number by moving the decimal point 1 places to the right. Then move the decimal point in the dividend the same, 1 places to the right.
We then have the equations:
2254 ÷ 23 = 98.000
and therefore:
225.4 ÷ 2.3 = 98.000
Both calculated to 3 decimal places.
