Two teams working together can finish a job in 8 days. if the first team works alone for two days and the second team works alone for 5 days, 5/8 of the total work still remains. How many days will it take each team to finish the work alone?
x is the days that the first team finishes the work alone (x>8)
y --------------------------second-----------------------------------------(y>8)
In a day:
The first team finishes 1/x (the work) The second team finishes 1/y (the work) Two teams working together finish 1/8 (the work)⇒ [tex]\frac{1}{x}+ \frac{1}{y} =\frac{1}{8}[/tex] (1)
If the first team works alone for two days and the second team works alone for 5 days, 5/8 of the total work still remains:
⇒ [tex]\frac{2}{x}+\frac{5}{y}=\frac{3}{8}[/tex] (2)
(1),(2) ⇒ [tex]\left \{ {{\frac{1}{x}+ \frac{1}{y} =\frac{1}{8}} \atop {\frac{2}{x}+\frac{5}{y}=\frac{3}{8}}} \right. <=>\left \{ {{x=16} \atop {y=24}} \right.[/tex]
It'll take the first team 16 days and the second team 24 days to finish the work alone

120 + 120 = 240. I do this to find the length sides of perimeterI can say that the depth, 80, is also the width. So, 80 + 80 = 160160 + 240 = 400. I do this to find the perimeterTherefore, 400 is the answer.Anand goes out to lunch. The bill, before tax and tip, was $10.80. A sales tax of 6.5% was added on.

In this exercise we have to use the conditions given in the statement, that is, when adding the extreme pairs they must give the middle number, so the only number that follows this condition is:
The next year to have to same property will be 2307
are analyzing the condition given in the statement and the example we can buy as follows:
[tex]1978 \rightarrow 19+78= 97 \\2307 \rightarrow 23+07= 30[/tex]
so the year 2307 corresponds to the conditions given in the statement.

Which number line correctly shows –0.8 + 0.6?
A number line going from negative 1.6 to positive 1.6. An arrow goes from negative 0.8 to negative 0.2, and then backwards from 0 to negative 0.8.
A number line going from negative 1.6 to positive 1.6. An arrow goes from 0 to negative 0.8 and then from negative 0.8 to negative 1.4.
A number line going from negative 1.6 to positive 1.6. An arrow goes from 0 to 0.8 and then from 0.8 to 1.4.
A number line going from negative 1.6 to positive 1.6. An arrow goes from negative 0.6 to 0.2 and then from 0 to negative 0.6.
Mark this and return
Answer:
Step-by-step explanation:
Since -0.8 is located to the left of origin so when adding any value it will cause it to shift to the right. For example, add 0.1 to 0.8, we get a value of 0.7 shifting the arrow to the right, same goes for 0.2
-0.8 + 0.1 = -0.7
-0.8 + 0.2 = -0.6
-0.8 + 0.4 = -0.4
-0.8 + 0.6 = -0.2
In this way it ends at -0.2
Step-by-step explanation: I hope this helps:)

What is the measure of the exterior angle? Show all steps.
Answer:
108 degrees
Step-by-step explanation:
The thereom for this is the interior angles (a+10) and 44 degrees add up equaling to 2a. This works for any triangle like this. So, a+10+44=2a, and we solve for a to 54 for a. Then we insert a as 54 for 2a to get 54*2=108 degrees.
