3 + 2k

This is because multiplying by 1/5 is like dividing each term by 5

Answer: Equivalent expression is 3+2k.

Step-by-step explanation:

Since we have given that

\dfrac{1}{5}(15+10k)

As we have to use "Distributive property":

a\times (b+c)=a\times b+a\times c

So, it becomes

\dfrac{1}{5}(15+10k)\\\\=\dfrac{1}{5}\times 15+\dfrac{1}{5}\times 10k\\\\=\dfrac{15}{5}+\dfrac{10k}{5}\\\\=3+2k

Hence, equivalent expression is 3+2k.

The perimeter of the rectangle below is 90 units. find the length of side vy . write your answer without variables.
Salsk061 [2.6K]
The picture in the attached figure

we know that
perimeter of a rectangle=2*[base+height]
base=3y+1
height=2y+3
perimeter=90 units
so
90=2*[(3y+1)+(2y+3)]-----> 90=2*[5y+4]----> 10y+8=90----> y=8.2 units

base=3y+1-----> base=3*8.2+1-----> 25.6 units
height=2y+3----> height= 2*8.2+3---> 19.4 units 

the answer is
<span>the length of side vy is (2y+3)-----> 19.4 units</span>

Step-by-step explanation:

let the number of kids in the camp be x

from the above situation, we get

=》70% of all kids in the camp is 210

=》

\frac{70}{100}  \times x = 210

=》

x =  210 \times  \frac{100}{70}

=》

x = 3 \times 100

=》

x = 300

Find the values of x and y
vitfil [10]

Hi there!

\large\boxed{y = 12, x = 3}

The two trapezoids are similar, so we can determine a common scale factor:

OL/UR = NM/TS

9/3 = 6/2

3 = 3

Trapezoid ONML is 3x larger than UTSR, so:

RS = 4, LM = y

3RS = LM

3 · 4 = y = 12.

Find x using the same method:

3UT = ON

3(2x+1) = 4x + 9

6x + 3 = 4x + 9

2x = 6

x = 3.
