Answer:

x is 35

Step-by-step explanation:

First do 180 -40 and get 140. Then add 3x plus x to get 4x because they are the same value/ Do 140/ 4x and get 35. X equals 35.

Answer:

35, 135

Step-by-step explanation:

You first add the like terms. 3x + x = 4x. Next you form an inequality.

40 - 4x = 180.

x = 35

Since x equals 35 you do 3 * 35. 3(35), which is 105.

35 + 40 + 105 = 180!

Please help me 16% of what is 41?

saul85 [17]

The answer is 256.25

EXPLANATION

Let $x$ represent the number.

Then, $\frac{16}{100}x=41$

We cross multiply yo obtain,

$16x=41\times 100$

We now divide both sides by 16.

$x=\frac{4100}{16}$

This will give us,

$x=256.25$

Therefore the number is 256.26

If YX=3x-4 and MO=9x-20, then MO=? {Diagram not necessarily drawn to scale.} *

Sveta_85 [38]

Answer:

Step-by-step explanation:

I assume that XY is midsegment of a triangle, then MO = 2 XY

9x - 20 = 2( 3x - 4 )

9x - 20 = 6x - 8

3x = 12

x = 4

MO = 9(4) - 20 = 16 units

Could someone help me with this pls

barxatty [35]

Answer:

7.99

Step-by-step explanation:

using the formula

$v = \pi \: r ^{2} h$

$3014.4 = 22 \div 7 \times r ^{2} \times 15$

$21100.8 = 22 \times 15 \times r {}^{2}$

$21100.8 = 330 \times r {}^{2}$

$21100.8 \div 330 = r {}^{2}$

$\sqrt{63.94 }= r$

$r = 7.99ft \: answer$
