Answer: Hi!
To simplify this expression, we will combine like terms.
-5a - 12a + 2b - 3b
-5a - 12a = -17a
2b - 3b = -1b
Our equation now looks like this:
-17a - 1b
We have nothing left to simplify, so we're done!

The second digit after the decimal point in a number is 4. What is the value of 4 in the number? 1 thousandth 4 thousandths 1 hundredth 4 hundredths
Answer:
D. 4 hundredths
Step-by-step explanation:
Hello!
The second digit after the decimal point is 4 is shown by
0.04
The points after a decimal point go tenths, hundredths, thousandths etc.
The answer is D. 4 hundredths
Hope this helps!
Answer:
4 hundredths
Step-by-step explanation:
For values of decimals one should note that each additional digit after the decimal is a multiple of (1/10).
Using this knowledge, the first digit would be tenths, the second digit hundredths, the third digit thousandths, etc.
Hence a 4 in the second digit after the decimal would be equivalent to 4 * (1/100) = (4/100) or 4 hundredths.

on a number line, suppose point E has a coordinate of 3, EG=6, and EX=12. is G the midpoint of EX? what are the possible coordinates for G and X?
Answer:
could be, isn't necessarilyG = -3 or 9; X = -9 or 15Step-by-step explanation:
If E is 3 and EG is 6, then ...
G = E ± EG = 3 ± 6
G = -3 or 9
If E is 3 and EX is 12, then ...
X = E ± EX = 3 ± 12
X = -9, or 15
__
If X and G have the same sign, then G will be the midpoint of EX. If not, then G is not the midpoint.
That is, -3 is halfway between -9 and 3, just as +9 is halfway between 3 and +15. On the other hand, -3 is not between 3 and 15; nor is 9 between 3 and -9.

3x-6y=18 slope intercept form
Answer:
[tex]y=\frac{1}{2}x-3[/tex]
Step-by-step explanation:
Start by writing the equation out as it is given in the question (in this case, in standard form).
[tex]3x-6y=18[/tex]
Next, subtract [tex]3x[/tex] from both sides.
[tex]3x-3x-6y=18-3x\\-6y=18-3x[/tex]
Switch around the [tex]18[/tex] and the [tex]-3x[/tex].
[tex]-6y=-3x+18[/tex]
Finally, divide the equation by [tex]-6[/tex] to get rid of the [tex]y-variable[/tex] coefficient, which is [tex]-6[/tex].
[tex]\frac{-6y}{6}=\frac{-3x+18}{-6}\\y=\frac{1}{2}x-3[/tex]
As shown in that last step, the equation is slope intercept form is: [tex]y=\frac{1}{2}x-3[/tex]
Answer:
y = 1/2x - 3.
Step-by-step explanation:
3x - 6y = 18
-6y = -3x + 18
Divide through by -6:
y = 1/2x - 3.

Writing and Solving an Equation to Find Negative Integers Two negative integers are 5 units apart on the number line, and their product is 126. What is the sum of the two integers
Answer:
-23
Step-by-step explanation:
Let first negative integer = x
The second = x +5
Their product = 126, hence,
x * (x +5) = 126
x^2 + 5x = 126
x^2 + 5x - 126 = 0
Two numbers whose product gives - 126 and sun gives 5
x(x + 14) - 9(x+14) =0
(x - 9) = 0 or (x + 14) = 0
x = 9 or x = - 14
Since x is said to be a negative integer,, the our x = - 14
First integer = - 14
Second integer = (x + 5) = (-14 + 5) = - 9
Sum of both integers :
-14 + - 9 = - 23

A child is hopping along a sidewalk. The ratio below shows the comparison between the number of hops and the distance traveled. Which statement correctly explains how to find the distance traveled after 150 hops?
Answer:
Find the ratio of hops to distance traveled (1: 1.5), then multiply 150 by 1.5.
Step-by-step explanation:
A child is hopping along a sidewalk. The ratio table below shows the comparison between the number of hops and the distance traveled. Hopping Number of hops Distance traveled (ft) 20 30 50 75 80 120 150 ?
Which statement correctly explains how to find the distance traveled after 150 hops? Subtract 120 – 75 to get 45, then add that number to 120. Add 30 + 75 + 120. Find the ratio of hops to distance traveled (1:1.5), then multiply 150 by 1.5. Find the ratio of hops to distance traveled (1:1.5), then divide 150 by 1.5.
Solution:
The table is:
No. of hops Distance traveled
20 30
50 75
80 120
150 ?
From the table, for every 30 increase in the number of hops, the distance travelled increase by 45 feet
Find the slope of the line:
m = (y2-y1) / (x2-x1)
m=slope of the line
y2-y1 = change in distance travelled
x-2 - x1 = Change in number of hops
m = (y2-y1) / (x2-x1)
m = (75-30) / (50-20)
=45 / 30
m = 1.5
Then, the line is:
y = 1.5x
We substitute x = 150
y = 1.5x
y = 1.5 × 150
y = 225

Answer:
a= 18 girls in the class, b= 20 boys and 15 girls, 12 oranges better price.
Step-by-step explanation:
for question a, there are 18 girls in the class, this is how i worked it out:
the ratio of boys to girls is 4:3.
there are 24 boys.
24 is 6 times more than 4.
if boys are 6 times more than the original ratio, we also have to times the amount of girls by 6.
6x3= 18.
for question b i got 20 boys and 15 girls, this is how i did it.
there are 35 students in total.
4:3= boys to girls.
4+3=7
7 goes into 35 five times.
ratio of boys to girls is 4:3 so 5x4 for boys = 20 and 3x5 for girls = 15.
answer= 20 boys and 15 girls.
12 oranges is a better deal, this is how i worked it out.
it is 60 for 12 oranges.
it is 48 for 8 oranges.
12x5= 60 , 8x6=48.
you only have to times 12 by 5 to get it to the price but you have to times 8 by 6 to get it to the price, proving that 12 oranges for 60 is a better deal.

Answer:
see below explanation
Step-by-step explanation:
1. 9 (x - 11) = 9
9x - (9 * 11) = 9
9x - 99 = 9
x = 12
2. 4 (3x - 2) = 52
(4 * 3x) - (4 * 2) = 52
12x - 8 = 52
x = 5
3. 44 = 2 (3x - 5)
44 = (2 * 3x) - (2 * 5)
44 = 6x - 10
x = 9
4. 2x- 4/5 = 4
2x - 2²/5 = 4
5(2x) + (-2²) / 5 = 4
x = 12 / 5
5. 3x + 2/2 = 13
3x + 1 = 13
(3x + 1) + (-1) = 13 + (-1)
x = 4
6. 4x -5/5 = 3
4x - 1 = 3
(4x - 1) + 1 = 3 + 1
x = 1
7. 10x + 4/7 = 8
10x + 2²/7 = 8
7(10x) + 2² / 7 = 8
x = 26 / 35
8. 6x - 1/2 = 1
2(6x) + (-1) / 2 = 1
((2 * 6x) - 1 ) / 2 = 1
x = 1/4
