what is the distance between -3/7 and 2/8
Answer:
[tex] \frac{19}{28} [/tex]
Step-by-step explanation:
distance between -3/7 and 2/8
[tex] = \frac{2}{8} - \bigg( - \frac{3}{7} \bigg) \\ \\ = \frac{2}{8} + \frac{3}{7} \\ \\ = \frac{2 \times 7}{8 \times 7} + \frac{3 \times 8}{7 \times 8} \\ \\ = \frac{14}{56} + \frac{24}{56} \\ \\ = \frac{14 + 24}{56} \\ \\ = \frac{38}{56} \\ \\ = \frac{19}{28} [/tex]
20. Matt is selling chocolate bars to make some extra money. In the first week of selling, he sold 2x2 + 3x − 1 chocolate bars. In the second week of selling, he sold 3x2 − 2x + 3 chocolate bars. If x = 2, how many chocolate bars did he sell in total over the two weeks?
Answer: 24
Step-by-step explanation:
Chocolate bars sold in first week:
= 2x² + 3x − 1
where x = 2
= 2x² + 3x − 1
= 2(2)² + 3(2) − 1
= (2×4) + 6 - 1
= 8 + 6 - 1
= 13
Second week
= 3x² - 2x + 3
= 3x² - 2x + 3
= 3(2)² - 2(2) + 3
= 12 - 4 + 3
= 11
Total chocolate sold = 13 + 11 = 24

Question 1 (1 point)
You play a game on your phone. For every correct move you make you recieve 50 points. For
every second that it takes you to complete the game you lose 3 points. You complete the game
in 2 minutes and 12 second using 30 correct moves. What is your score?
a) Write the expression used to solve the problem?
b) What is your score?
Answer:
A it is addition
B it is 97
Answer:
1,104 points
Step-by-step explanation:
First I figured out how many seconds it took to finish the game (132)
Then I figured out how many points he got by multiplying 30x50=1,500
After that, I multiplied 3 and the number of seconds that it took to finish the game (3x132) and that gave me the answer of 1,104 points
m > 5m-4
Pls solve and show steps hurry pls !!!!
Answer:
move 5m over the sign so it is like this m-5m>-4 subract it will be-4m>-4 divide both sides by-4 m=1 negative divided by a negative is a positive
the answer is m<1
I subtracted 5 from both sides to get m-5m>-4
I simplified it to -4m>-4
divided both sides by -4 and got m<1 as the answer
solve for a and b
(6a-3)=(7b-10)
Answer:
for A=[tex]\frac{7b-7}{6}[/tex] and for B=[tex]\frac{6a+7}{7}[/tex]
Step-by-step explanation:
For A
[tex]\left(6a-3\right)=\left(7b-10\right)[/tex]
[tex]6a-3+3=7b-10+3[/tex]
[tex]6a=7b-7[/tex]
[tex]\frac{6a}{6}=\frac{7b}{6}-\frac{7}{6}[/tex]
[tex]a=\frac{7b-7}{6}[/tex]
For B
[tex]\left(6a-3\right)=\left(7b-10\right)[/tex]
[tex]7b-10=\left(6a-3\right)[/tex]
[tex]7b-10=6a-3[/tex]
[tex]7b-10+10=6a-3+10[/tex]
[tex]7b=6a+7[/tex]
[tex]\frac{7b}{7}=\frac{6a}{7}+\frac{7}{7}[/tex]
[tex]b=\frac{6a+7}{7}[/tex]
solve the inequality 2(x+5)>8 ?
Answer:
2(x+5)>8
Step-by-step explanation:
=
x>-1
hope that's it
Hi!
I can help you with joy!
No worries, we can solve this inequality easily. :)
First of all, let's use the Distributive Property and distribute 2:
[tex]\rm{2(x+5)>8[/tex]
[tex]\rm{2x+10>8[/tex]
Now, move 10 to the right, using the opposite operation:
[tex]\rm{2x>8-10[/tex]
Subtract:
[tex]\rm{2x>-2[/tex]
Final Step: Divide both sides by 2.
[tex]\rm{x>-1[/tex] (Answer)
Hope it helps!

You are researching the average emails received per day. You want to know how many employees you should survey if you want to know, at a 90% confidence level, that the sample mean emails per day is within 47 emails of the true mean emails per day. From above, we know that the population standard deviation is 155, and z-value is 1.645$_
Answer:
The value is [tex]n =29 \ employees [/tex]
Step-by-step explanation:
Generally the number of employee to survey(sample size) is mathematically represented as
[tex]n = [ \frac{z * \sigma }{E} ]^2[/tex]
Here E is the margin of error which is given as E = 47
So substituting 1.645 for z and 155 for [tex] \sigma[/tex]
[tex]n = [ \frac{1.645 * 155 }{47} ]^2[/tex]
=> [tex]n =29 \ employees [/tex]
whats 2+34233-2943+291*45=
what the anwser??????????????
Answer:
44387
Step-by-step explanation:
Answer:
1421235
Step-by-step explanation:
2 + 34233 = 34235 - 2943 = 31292 + 291 = 31583 x 45 = 1421235
2 + 34233 = 34235 - 2943 = 31292 + 291 = 31583 ➗ 45 = 701.844444444
If its multiplication the answer is = 1421235
If division the answer is = 701.844444444 (calculator) or 701 r 38 (my brain)
Question: 11.23 x 10 to the power of 5, the answer is 11.2300000.
Explanation: multiple 10 x 10 x 10 x 10 x 10 = 10,000, then multiple 11.23 x 10,000 = 112300000, add the decimal places = 11.2300000.
Question: 11/20 a repeating or terminating decimal,
Answer: is terminating.
Question: 7 * 73 + 43, the answer is 554.
Explanation: multiple 7 x 73 = 511 + 43 = 554. If division then divide 7 into 73 = 10.4285714286 + 43 = 53.4285714286 (calculator answer). 7 into 73 = 1 r 3 = 1.3 + 43 = 44.3 or 44 r 3 (my brain answer).

What do the horizontal lines in an elevation-versus-time graph mean?
-10 = -b/4
solve for b, show steps please
Answer:
b = 40
Step-by-step explanation:
-b/4 = - 10 Multiply both sides by 4
-b/4 * 4 = - 10 * 4
- b = - 40 Multiply both sides by -1
(-1) * (-b) = (-40)(-1)
b = 40

Thirteen less than twice a number is fifteen. What is the equation? What is the number?
Hi there!
Let the unknown number be c.
Twice a number means we multiply that number by 2:
2c
Now, subtract 13:
2c-13
This expression is equal to 15:
2c-13=15
As soon as I added the equal sign, and the number than the expression is equal to, the expression turned into an equation.
Now, let's solve it for c.
2c=15+13
2c=28
c=14
Hope everything is clear :-)
