What is the answer to
−1.4 + (−1.2) ?
(I've looked everywheres on Brainly and found no answers that I need.)
Answer:
-1.6
Step-by-step explanation:
Since they're both negative and you're adding, you would do the same if you added normally, but you would add a negative sign.
Answer:
-2.6
Step-by-step explanation:
-1.4 + (-1.2)
-1.4 - 1.2
-(1.4+1.2)
-2.6
Remember that adding a negative is the same as subtracting a positive.

Job A: $8.95 per hour (40 hours a week)Job B: $16,400 per year
a. Which job pays more?
b. How much more?
Answer:
A) Job A pays more.
B) $784 dollars more than job B.
Step-by-step explanation:
We know that job B Makes $16,400 per year. We just need to find out how much job A makes in a year.
Job A: 8.95 x 40= $358 in a week.
We know that there is 4 weeks in a month and 12 months in a year.
12 x 4 = 48.
48 weeks in a year x $358 in a week= $17,184
We now know that job A pays more than iob B.
In order to find out how much more we will use the formula Job A- Job B= Difference between.
$17,184-$16,400= $784
Job A pays $784 dollars more than job B.
Your printer takes 36 seconds to print a small photo and 60 seconds to print a large one.
a.) Write an expression for the time (in seconds) your printer would take to print a batch
including both small and large photos.
b.) Find the time your printer would take to print 12 small photos and 5 large photos.
Answer: for part B = 732 seconds or 12.2 minutes
Step-by-step explanation: 36 seconds times the amount of small photos 12 = 432 plus 60 seconds times the amount of large 5 photos = 300 , 432 plus 300 equals 732 seconds
(36 x 12) + (60 x 5) = 732

A contractor buys screws for $1.55 per box and nails for $1.05 per box, Write an equation for the total
cost. Then find the cost of 3 boxes of screws and 5 boxes of nails.
Answer:
1) $2.6
2) $9.9
Step-by-step explanation:
for the first one, you first add $1 with 1$ and you would get 2 and then you do 55 cents plus 5 cents which would get 60 cents and then you get $2.60.
For the second one, you multiply 2.60 by 3 and you get $7.80 and you still have $2.10 left so you add that to $7.80 then you get $9.9

Hi there!
(z)
We know that the two segments with "z" are congruent, so:
z + 15 = 5z + 9
Solve for z:
15 = 4z + 9
6 = 4z
z = 3/2
(y)
We know that (7y + 6) = 90° (indicated by the square angle), so:
7y + 6 = 90
7y = 84
y = 12°
(x)
Segments (x + 26) and (3x - 8) are congruent, so:
x + 26 = 3x - 8
26 = 2x - 8
34 = 2x
x = 17
Brother’s homework..
Answer:
1 1/12
1 11/12
Step-by-step explanation:
Cross multiply 3/4 and 1/3 which gives you 9/12 and 4/12
Add them together 9/12 + 4/12 = 13/12
Reduce 13/12
1 1/12
So she needs 1 11/12 more
A cab company charges $3 per cab ride,
plus an additional $2 per mile driven. How
long is a cab ride that costs $11?
miles
Answer:
The answer is c = 2 + 3d .
Step-by-step explanation:
It is given that a cab ride cost $2 which is a fixed amount and charges additional $3 per mile. So you have to make an equation of c in terms of d :
Let c be the cost,
Let d be the distance,
c = 2 + 3d
The accompanying data set lists the numbers of children of world leaders. Use the data to construct a frequency distribution using six classes and to create a frequency polygon. Describe any patterns.
Frequency polygons are used to show the trend between the elements of a given dataset and the frequency of each element.
From the dataset, we have the following class of 6 and the frequency:
[tex]Class \to Frequency[/tex]
[tex]0 - 2 \to 9[/tex]
[tex]3 - 5 \to 18[/tex]
[tex]6 - 8 \to 7[/tex]
[tex]9 - 11\to 0[/tex]
[tex]12 - 14 \to 5[/tex]
[tex]15 - 17 \to 4[/tex]
So, the frequency distribution is as follows:
[tex]\begin{array}{ccc}{Class}&{Frequency}&{x}\\0-2&9&1\\3-5&18&4\\6-8&7&7\\9-11&0&10\\12-14&5&13\\15-17&4&16\end{array}\right][/tex]
The class midpoint (x) is calculated by calculating the mean of each class.
For instance, the midpoint (x) of class 0 - 2 is:
[tex]x = \frac{1}{2}(0+2) = \frac{1}{2} \times 2 =1[/tex] ---- and so on
The class midpoint (on the x-axis) is plotted against the frequency (on the y-axis) to create the frequency polygon (see attachment)

The vending machine has sodas in a ratio of 3 Pepsi to 4 coke. If there are 24 Pepsis in the machine, how many total sodas are there?
Answer:
56 sodas
Step-by-step explanation:
3 pepsi: 4 coke so to get 24 pepsi: x coke you'd have to multiply the ratio by 8 --> this leads you to 24 pepsi: 32 coke
Add pepsi value and coke value to get total number of sodas:
24 + 32 = 56

Ken went to a county fair and spent $5 on admission, $6.50 on games, and $7.21 on food. If he had $30 before he went to the fair, how much money does he have left?
Answer:
Below
Step-by-step explanation:
To find Ken's leftover amount of money, all you need to do is subtract what he spent from his initial amount :
$30 - $5 - $6.50 - $7.21 = $11.29
So, Ken has $11.29 left after he goes to the fair

Simplify the expression by combining like
terms. Write the terms from the highest to the
lowest power of the variable.
7b^2- b + 3b + 6 - 3b^2+ 5 + 2b^2+ 7b
Answer:
Below
Step-by-step explanation:
First we combine your first set of terms,
7b^2 + 2b^2 = 9b^2
There's a subtraction hidden in there!
9b^2 - 3b^2 = 6b^2
Next we do the same thing for the second term,
3b + 7b = 10b
but there's a subtraction in the expression!
10b - b = 9b
Then we finish with our third term
6 + 5 = 11
Answer:
6b^2 + 9b + 11
