A single bead weighs 6 grams, so 8 beads would weigh 48 grams.

if 5 grams weigh 30 then each gram weigh 6 grams 5x6=30 so 48 grams would weigh 8 48x8=384

Rufina [12.5K]

Answer:

Simplifying

logx + -4 = 0

Reorder the terms:

-4 + glox = 0

Solving

-4 + glox = 0

Solving for variable 'g'.

Move all terms containing g to the left, all other terms to the right.

Add '4' to each side of the equation.

-4 + 4 + glox = 0 + 4

Combine like terms: -4 + 4 = 0

0 + glox = 0 + 4

glox = 0 + 4

Combine like terms: 0 + 4 = 4

glox = 4

Divide each side by 'lox'.

g = 4l-1o-1x-1

Simplifying

g = 4l-1o-1x-1

When Mei does 17 push-ups and 6 sit-ups, it takes a total of 35 seconds. In comparison, she needs 41 seconds to do 20 push-ups a

Romashka [77]

Answer:

It takes 1 seconds for push-ups and 3 seconds for sit-ups for Mei to do exercise.

Step-by-step explanation:

Given:

Let the time taken for push-ups be 'x'.

Let the time taken for sit-ups be 'y'.

Now Given:

17 push-ups and 6 sit-ups, it takes a total of 35 seconds.

So we can say that;

$17x+6y=35 \ \ \ \ equation \ 1$

Also Given:

41 seconds to do 20 push-ups and 7 sit-ups.

so we can say that;

$20x+7y=41 \ \ \ \ equation \ 2$

Now Multiplying equation 1 by 7 we get;

$7(17x+6y)=35\times7\\\\119x+42y= 245 \ \ \ \ equation \ 3$

Now Multiplying equation 2 by 6 we get;

$6(20x+7y)=41\times6\\\\120x+42y = 246 \ \ \ \ equation\ 4$

Now Subtracting equation 3 from equation 4 we get;

$120x+42y-(119x+42y)=246-245\\\\120x+42y-119x-42y=1\\\\x=1\ sec$

Now substituting the value of x in equation 1 we get;

$17x+6y=35\\\\17\times1+6y=35\\\\17+6y=35\\\\6y=35-17\\\\6y= 18\\\\y=\frac{18}6 = 3\ seconds$

Hence It takes 1 seconds for push-ups and 3 seconds for sit-ups for Mei to do exercise.

Ulleksa [173]

I am going to graph the situation on an external graphing utility and show you the answer, it will take a

minute, stay with me.

$m\text{ = }\frac{rise\text{ }}{\text{run}}=\frac{change\text{ in y}}{\text{change in x}}=\frac{3}{1}=3$ $y\text{ = mx+b}\rightarrow\text{ b =-1}$

So the equation of the line is.

$y\text{ =3x -1}$ $y\text{ -1 = m(3-0)}$

8. Solve the system of equations using substitution.

Elodia [21]

Answer:

Step-by-step explanation:

In order to solve this we need to plug in the answer choices and make sure they work for BOTH answers!

Let us start with option A. (6,3) 3 = 4(6) + 6 = 3 = 30 This is automaticly wrong because 3 doesnt equal 30. There is no need to try it on the second equation since the first one was wrong.

Next answer choice, B (3,6) 6 = 2(3) = 6=6. The second equation works perfect for this. Now we have to make sure that it works for the first one as well. 6 = 4(3) + 6 = 6 = 18 which is wrong.

Next, C. (1,2) 2 = 2(1) = 2=2 Right now lets check the other equation.

2 = 4(1) + 6 = 2=10. Wrong

Last, D. (-3, -6) -6 = 2(-3) = -6 = -6 Right now lets check the other equation.

-6 = 4(-3) + 6 = -6 = -6. CORRECT. Answer choice D works for both equations.

Sorry for the wait of response.
