Five more than 3/4 a number is -19

Mathematics
1 answer:
irinina [24]4 years ago
3 0

Answer:

-32

Step-by-step explanation:

Let the number be x

so the equation becomes

5+(3/4)x= -19

5+3x/4= -19

Multiplying b.s by 4

5*4+(3x/4)*4= -19*4

20+3x= -76

3x= -76-20

3x= -96

Dividing both sides by 3

x= -32

34699 to nearest ten thousand
xz_007 [3.2K]

Ones place: 9

Tens place: 9

Hundreds place: 6

Thousands place: 4

Ten thousands place: 3

Which is 34,699

Now that we know 3 is in the ten thousand's place.

So then go from 3, and jump too 4. If the number is higher then 5, the 3 would become a 4. If the number is lower then 5, 4 would become a 0 and so will the rest of the number's too the right.

34,699 ---> 30,000

That being said, the answer is 30,000!

I hope this help's! :)

Find the measures of supplementary angles 1 and 2, if: m∠1:m∠2=5:4 using statements and reasons.
adell [148]

Answer:

<h2>m∠1 = 100°, m∠2 = 80°</h2>

Step-by-step explanation:

We know: Supplementary angles add up to 180°.

Therefore

m∠1 + m∠2 = 180° → m∠2 = 180° - m∠1     (*)

We have

m\angle1:m\angle2=5:4\to\dfrac{m\angle1}{m\angle2}=\dfrac{5}{4}

Substitute (*):

\dfrac{m\angle1}{180^o-m\angle1}=\dfrac{5}{4}           <em>cross multiply</em>

4m\angle1=5(180^o-m\angle1)        <em>use the distributive property</em>

4m\angle1=(5)(180^o)+(5)(-m\angle1)

4m\angle1=900^o-5m\angle1          <em>add 5m∠1 to both sides</em>

9m\angle1=900^o         <em>divide both sides by 9</em>

m\angle1=100^o\to m\angle2=180^o-100^o=80^o

What conclusion can be drawn by observing that 30 is to the right of 10 on a
enyata [817]

The correct answer is B. 30 > 10

Explanation:

In mathematics and related fields, number lines are straight lines that display numbers using intervals this is useful to represent quantities visually, for example in graphs. Additionally, in number lines, numbers are organized in ascending order from left to right, for example, number 1  will be placed to the left of number 2. According to this, number 30 placed to the right of 10 will represent a higher quantity, considering the more you go to the right the higher the number is. Thus, 30 is greater than 10 (30 > 10).

5. -4n + 7 + 2n =1
Minchanka [31]
5.
-4n+ 7+ 2n= 1
⇒ (-4n+ 2n)+ 7= 1 (combine like terms)
⇒ -2n= 1-7
⇒ -2n= -6
⇒ n= -6/(-2)
⇒ n= 3

Final answer: B. 3~

6. 4(y-4)= 8
⇒ y-4= 8/4
⇒ y-4= 2
⇒ y= 2+4
⇒ y= 6

Final answer: D. 6~
