Okay! Let's think simply about this and set up an equation.

18 votes + 22 votes + y votes = ?

It has to equal 68 votes because the problem says <em>everyone voted. </em>

All we need to do to figure out how much y is, is to subtract 18 and 22 from 68.

That way, we are left with however many votes the student gave to the <em>3rd candidate. </em>

<u>18 + 22 + y = 68 </u>

<u>y = 68 - 18 - 22 </u>

<u>y = 28 </u>

Your answer is 28 votes

Marsha uses 8.5 pints of white paint and blue paint to paint her bedroom walls. 2/5
Serjik [45]

Answer:

5.1 pints

Step-by-step explanation:

Theres 2 ways

First way:

We can do 2/5 of 8.5 which is 3.4. Then, we can subtract 3.4 from 8.5 and get 5.1 pints.

Second way:

We can simply do 3/5 of 8.5 because the remaining 3/5 of the paint is blue. 3/5 of 8.5 is 5.1 pints

Hope this helped! I would appreciate a Brainliest if this helped you!

Write the explicit formula that represents the geometric sequence -2, 8, -32, 128
MissTica
So hmm the first term is -2

and if we divide one term by the term before it, we'd get the "common ratio" "r"

so hmm say -32/8 that gives us -4, so r = -4

thus \bf n^{th}\textit{ term of a geometric sequence}\\\\&#10;a_n=a_1r^{n-1}\qquad &#10;\begin{cases}&#10;a_1=\textit{first term}\\&#10;r=\textit{common ratio}\\&#10;----------\\&#10;a_1=-2\\&#10;r=-4&#10;\end{cases}\implies a_n=-2(-4)^{n-1}

mars1129 [50]

Answer:

Step-by-step explanation:

first we need to calculate the area of isosceles triangle having sides 48cm, 48cm and 30cm

a = 48

b= 30

Area of isosceles triangle using only sides = ½[√(a^2 − b^2 /4) × b]

= 1/2*30√( 48² - 1/4×30²)

=1/2*30√ (2304 -225)

=684sq cm

cost required to make umbrella= 10*684*5

= 3<em>4200</em>

z = 3m - 2n

Step-by-step explanation:

1000^m ÷ 100^n

Rewrite them in exponent form

That's

10^3m ÷ 10^2n

Since the bases are the same and they are dividing we subtract the exponents

That's

10^3m - 2n

Comparing it with 10^z

10^3m - 2n = 10^z

z = 3m - 2n

Hope this helps you
