-3-4y=-23 -3x+y=2 using elimination

Answers

I think you are missing an x in the equation -3 - 4y= - 23.

If not, then multiply -3x + y = 2 by 4. This will eliminate y.

4(-3x + y) = 4(2)

-12x + 4y = 8
-3 - 4y = - 23

Do you see that 4y and -4y disappear?

-15x = -15

x = -15/-15

x = 1

9,791 rounded to the nearest hundred

Answers

9,800 is your answer

9,791 rounded to the nearest hundred is 9,800 because the tens digit (9) is closer to 0 than 100.

Rounding 9,791 to the nearest hundred means finding the closest multiple of 100 to 9,791. To do this, we look at the tens digit, which is 9, and determine if it's closer to 0 or 100. Since 9 is closer to 0 than to 100, we keep the hundreds digit the same (9) and change all digits to the right to 0. So, rounding 9,791 to the nearest hundred gives us 9,800.

Two lines intersect to form a linear pair with equal measures. One angle has the measure 9x° and the other angle has the measure (9y − 54)°. Find the values of x and y.

Answers

My understanding is that the 2 angles add up to 180 degrees, so 9x+9y-54=180. Also, 9x=90 and 9y-54=90. 9x=90, so x=10. 9y=90+54. 9y=144. y=16.

what is 235 written as a product of prime factors?

Answers

235/5 = 47

5 and 47 are prime, so

235 = 5 * 47
5 divides into 235 without a remainder; the quotient is 47.  47 is prime; it does not have integer factors other than 1 and 47.

Thus, 235 = 5(47)   (answer:  product of prime factors)

Morgan plots the point (4,-7) on a coordinate plane. If she reflects the point aacross the y axis, what are the coordinates of the reflected point?

Answers

(-4,-7) 


The x coordinate just becomes a negative
If you imagine a coordinate plane, there are 4 sections.
1 : (+,+)
2 : (-,+)
3 : (-,-)
4: (+,-)

Now, point (4,-7) is in the 4th section. Meaning, the reflection over the y-axis would be in the 3rd section. It would be (-,-)

The reflection over the y-axis of (4,-7) is (-4,-7).

It has to be the surface of the water, stone was 8ft above the surface.
depth is height of ground to surface.
level it fell was 8 ft
if level it was thrown was 0 then the surface would be -8ft

ab + 3c = 2x, for b

Answers

Ab + 3c = 2x

Subtract 3c from both sides.

ab = 2x - 3c

Divide a from both sides.

b = 2x - 3c / a

Hope this helps!
Final answer:

To solve the equation ab + 3c = 2x for b, subtract 3c from both sides and divide by a.

Explanation:

To solve the equation ab + 3c = 2x for b, we need to isolate b on one side of the equation. First, subtract 3c from both sides to get ab = 2x - 3c. Then, divide both sides by a to get the final solution: b = (2x - 3c) / a.

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y.

Where, x and y are individual amount of two quantities.

And, Total quantity gives after combine as x + y.

Given that;

The ratio of dolls to teddy bears is,

⇒ 9 : 3

Number of dolls in the store = 240

Now,

Since, The ratio of dolls to teddy bears is,

⇒ 9 : 3

⇒ 3 : 1

So, Number of dolls = 3x

And, Number of teddy bears = x

⇒ 3x = 240

Solve for x as;

⇒ x = 240 / 3

⇒ x = 80

Thus, Number of teddy bears = x
