18 (m + 4/9) - 16 = 118 Get rid of the parentheses by multiplying 18 * M + 4/9

18M + 8 - 16 = 118 Subtract 8 - 16

18M - 8 = 118 Add 8 to both sides

18M = 118 + 8 Add 118 + 8

18M = 126 Divide 126/18

M = 7

18(m+4/9)-16=118
18m+18*(4/9) -16 = 118 (i used distributive property)
18m+8 -16 = 118
18m-8 = 118
18m = 126 ( i added 8 to both sides)
m = 126/18
m = 7

Two containers, A and B begin with equal volumes of liquid.

Reika [66]

Answer:

volume left in A is 80ml

Step-by-step explanation:

let original volume in both be x ml

after pouring from A to B

vol in A = x - 120

vol in B = x + 120

now it is given that

vol in B = 4 times vol in A

implies

$x + 120 = 4 \times (x - 120) \\ x + 120 = 4x - 480 \\ 3x = 600 \\ x = 200$

hence original volume in A is 200ml. after pouring in B it is 200-120 = 80 ml

The sum of two numbers is 18. The larger number is twice as large as the smaller number. What are the two numbers? Please explai

snow_tiger [21]

The two numbers are 12 and 16. 12 + 6 = 18. 6 doubled is 12. 12 plus 6 equals 18.

A Speedboat increases in speed uniformly from 20m/s to 30m/s for 12.2 s. What is the acceleration of the speedboat?

Aloiza [94]

Answer:

0.82 m/s^2

Step-by-step explanation:

Given data

initial velocity=20m/s

Final velocity= 30m/s

Time = 12.2s

Applying the formula

a= v-u/t

a= 30-20/12.2

a= 10/12.2

a= 0.819

a=0.82 m/s^2

The number of kilograms of water in a human body varies directly as the mass of the body. An 87-kg person contains 58 kg of wat

katen-ka-za [31]

Answer:

50 kg water.

Step-by-step explanation:

We have been given that the number of kilograms of water in a human body varies directly as the mass of the body.

We know that two directly proportional quantities are in form $y=kx$ , where y varies directly with x and k is constant of variation.

We are told that an 87-kg person contains 58 kg of water. We can represent this information in an equation as:

$58=k\cdot 87$

Let us find the constant of variation as:

$\frac{58}{87}=\frac{k\cdot 87}{87}$

$\frac{29*2}{29*3}=k$

$\frac{2}{3}=k$

The equation $y=\frac{2}{3}x$ represents the relation between water (y) in a human body with respect to mass of the body (x).

To find the amount of water in a 75-kg person, we will substitute $x=75$ in our given equation and solve for y.

$y=\frac{2}{3}(75)$

$y=2(25)$

$y=50$

Therefore, there are 50 kg of water in a 75-kg person.
