Answer:-12

Step-by-step explanation:

22-?=10

22-12=10

so, -12+22=10

because when you add a negative it is like you are subtracting.

Answer:

-32

Step-by-step explanation:

you have to be in the negatives because 22 is bigger than 10.

Tip that will save you time:

when you have an equation like this just add the two numbers together and then add a negative sign :D

22+10= 32

-32

Someone help with these its due tomorrow. Ahhhh
Oksana_A [137]
I'll help with 1.) 
9m:3m = 6m:x
cross multiply
9x=3*6
9x=18
divide both sides 9
x = 2
the missing side is 2m

The missing angle is 30°

Question 2.)
find the ratios to solve for missing side
24:6 = b:4
cross multiply
24*4 = 6b
96 = 6b
divide both sides by 6
16 = b

The missing angle is 32°

Question 3.)
Find missing side d
make a ratio
5:d = 3:9
cross multiply
5*9 = 3d
45 = 3d 
divide both sides by 3
15 = d

the missing angle is 90°

Question 4.)
Find missing side s
write as proportion or ratio
36:6 = s:2
cross multiply
36*2 = 6s
72 = 6s
divide both sides by 6
s = 12

The missing angle t is 71°

Hope this helps :)

1/4(X-10)=2X+1 <br><br> what is X?
In-s [12.5K]

Answer: x=-2

Step-by-step explanation:

\frac{1}{4}(x-10)=2x+1

Distribute 1/4

\frac{1}{4}x-\frac{1}{4}(10)=2x+1

\frac{1}{4}x-\frac{5}{2}=2x+1

add 5/2

\frac{1}{4}x-\frac{5}{2}+\frac{5}{2}=2x+1+\frac{5}{2}

\frac{1}{4}x=2x+\frac{1*2+5}{2}

\frac{1}{4}x=2x+\frac{2+5}{2}

\frac{1}{4}x=2x+\frac{7}{2}

Subtract 2x

\frac{1}{4}x-2x=2x-2x+\frac{7}{2}

\frac{1}{4}x-2x=\frac{7}{2}

\frac{1-2*4}{4}x=\frac{7}{2}

\frac{1-8}{4}x=\frac{7}{2}

-\frac{7}{4} x=\frac{7}{2}

Multiply by the negative reciprocal of -7/4 which is basically inverting the fraction -4/7

(-\frac{4}{7} )-\frac{7}{4} x=\frac{7}{2}(-\frac{4}{7} )

x=-\frac{28}{14}\\ x=-2

A web music store offers two versions of a popular song. The size of the standard version is 2.3 megabytes (MB). The size of the
Effectus [21]

answer

240 standard versions

set up equations

s = number of standard versions

h = number of high quality versions

the total size of all standard versions would be 2.3s since each standard version is 2.3 MB

the total size of all high quality versions would be 4.4h since each standard version is 4.4 MB

add them together to get the total size (2664 MB) of all versions

2664 = 2.3s + 4.4h

since the high quality version was downloaded twice as often as the standard, we can say that

h = 2s

substitute h into equation and solve

2664 = 2.3s + 4.4h

h = 2s

2664 = 2.3s + 4.4(2s)

2664 = 2.3s + 8.8s

2664 = 11.1s

s = 2664/11.1

s = 240

Graft the solution to the inequality on the number line. <br><br><br> m&gt;2.8
Oduvanchick [21]

Answer:

See the graph of the given inequality in the attachment as shown below:

Step-by-step explanation:

Given the inequality: m > 2.8

To graph this inequality on the number line.

Remember:

  • If the symbol is (\geq or \leq) then you fill in the dot
  • If  the symbol is (> or then you do not fill in the dot.

Since, in the given inequality the symbol is '>'

Now, sketch a number line and draw an open circle around the number 2.8.

You can see the number line as shown below in the attachment.
