<h2>Answer with explanation:</h2>

We are given a equation as:

$3x-y=5(y+2x)$

We are asked to translate this equation into verbal sentence i.e. we have to translate the mathematical expression to words.

The translation is:

<em>" 3 times a number "x" minus the other number "y" is equal to 5 times the sum of y and 2 times of x "</em>

( Since, 3x means 3 times of x.

and now this expression is subtracted from y such that the left hand side of the equation is: 3x-y

and in the right hand side of the equation we have the expression: 5(y+2x)

which is 5 times of the expression y+2x

which is y plus the 2 times of x )

Would the missing value be 12cm?

nika2105 [10]

Answer: The missing value, y = 24

Step-by-step explanation:

The triangles are similar, so the sides are proportional.

The length of side BD is 10. The segment AD is also 10. Add them to get the length of side AB.

DE is 12

12:10 = y:20 . 20/10 = 2 2×12 = 24

Mrs. Eaton's class is participating in the "Box Tops for Education" campaign. On the first day, her

storchak [24]

Each colection day: D
Number of tops collected on that day: N

D1=1; N1=2
D2=3; N2=8

1) Linear model
N-N1=m(D-D1)

m=(N2-N1)/(D2-D1)
m=(8-2)/(3-1)
m=(6)/(2)
m=3

N-N1=m(D-D1)
N-2=3(D-1)
N-2=3D-3
N-2+2=3D-3+2
N=3D-1

when D=6:
N=3(6)-1
N=18-1
N=17

<span>What is the number of tops collected on the sixth day based on the linear model?
</span>The number of tops collected on the sixth day based on the linear model is 17.

2) Exponential model
N=a(b)^D
D=D1=1→N=N1=2→2=a(b)^1→2=ab→ab=2 (1)

D=D2=3→N=N2=8→8=a(b)^3→8=a(b)^(1+2)
8=a(b)^1(b)^2→8=ab(b)^2 (2)

Replacing (1) in (2)
(2) 8=2(b)^2
Solving for b:
8/2=2(b)^2/2
4=(b)^2
sqrt(4)=sqrt( b)^2 )
2=b
b=2

Replacing b=2 in (1)
(1) ab=2
a(2)=2
Solving for a:
a(2)/2=2/2
a=1

Then, the exponential model is N=1(2)^D
N=(2)^D

When D=6:
N=(2)^6
N=64

<span>What is the number of tops collected on the sixth day based on the exponential model?
</span><span>The number of tops collected on the sixth day based on the exponential model is 64</span>

The science club sponsors and ordering In church for the boys and girls in science called their forty-five sure science club num

Oliga [24]

Answer:

The Science club would required 15 packs of caps and 9 packs of shirts to fulfill the needs of each member.

Step-by-step explanation:

Given:

Number of caps in each pack = 3

Number of Shirts in each pack = 5

Total members of club = 45

Number of caps needed = 45

Number of shirts needed = 45

we have to find the least number of packs of caps and shirts that they need to buy in order to fulfill the needs of each member.

Solution:

Now we can say that;

number of packs of caps required can be calculated by Number of caps needed divided by Number of caps in each pack.

framing in equation form we get;

number of packs of caps required = $\frac{45}{3} = 15\ packs$

Also We can say that;

number of packs of Shirts required can be calculated by Number of Shirts needed divided by Number of Shirts in each pack.

framing in equation form we get;

number of packs of Shirts required = $\frac{45}5} = 9\ packs$

Hence The Science club would required 15 packs of caps and 9 packs of shirts to fulfill the needs of each member.
