How do I solve this???? Simply the following 3 2/7 + 2 3/14 + 4 3/7.

Oduvanchick [21]

Answer:

f(6) = 35

Step-by-step explanation:

f(6) means the function value for the x-coordinate 6. To find this, we need to find out which function to use (either 0 or 35x-175). 0≤x≤5 means that f(x)=0 for any value between 0 and 5 and including 0 and 5 themselves. However, we need to find the value for x=6, so we need to use the other function (35x-175). This gives us:

f(6) = 35 * 6 - 175 = 210 - 175 = 35

I hope this helps!

Twelve shirts and three pairs of jeans cost $85.95 . Fifteen shirts and 2 pair of jeans costs $93.55.

Nesterboy [21]

Answer:

12s +3j= 85.95

15s +2j= 93.55

Step-by-step explanation:

First, define the variables:

Let the cost of a shirt be $s and the cost of a pair of jeans be $j.

From the first sentence:

12s +3j= 85.95 -----(1)

From the second sentence:

15s +2j= 93.55 -----(2)

How do I get from: Sin x = -1/2 To: x = 7Pi/6, 11Pi/6

brilliants [131]

A few ways. you can enter it into a calculator for one, but the easiest way would be to reference a unit circle and look for an ordered pair where sin (the y value), is equal to -1/2

on a unit circle, the sin value is -1/2 at 7pi/6 and 11pi/6

because sin is the y value, it will additionally be in the quadrants III or IV based on the fact that (-1/2) as a sin value IS a negative and would have to be found in a quadrant in which sin is negative (the lower half of a coordinate plane, in this case)

Triangle Proportions pls help find ? ive been trying for 20 mins

Pachacha [2.7K]

Let missing side be x

$\\ \sf\longmapsto \dfrac{2}{5}=\dfrac{x}{10}$

Now

$\\ \sf\longmapsto 5x=20$

$\\ \sf\longmapsto x=\dfrac{20}{5}$

$\\ \sf\longmapsto x=4$

bob is twice as old as chuck, and susie is 10 years younger then bob if sum of their ages is 100 years how old is susie

Lina20 [59]

Answer:

The age of Susie is 34 years .

Step-by-step explanation:

Given as :

The statement is ,

Bob is twice as old as Chuck,

Susie is 10 years younger then Bob

The sum of age of Bob , Chuck , Susie = 100 years

Let The age of Bob = B years

Let The age of Chuck = C years

Let The age of Susie = S years

Now, According to statement

Age of Bob + Age of Chuck + Age of Susie = 100 years

i.e B + C + S = 100 years ........1

Again

Age of Bob = 2 × age of Chuck

i.e B = 2 C .......2

Again

Age of Susie = Age of Bob - 10 years

i.e S = B - 10

∵ B = 2 C

So, S = 2 C - 10 ........3

Solving equations 1 , 2 , 3

Put the vale of eq 2 and eq 3 into eq 1

So, 2 C + C + (2 C - 10) = 100

Or, (2 C + C + 2 C ) - 10 = 100

Or, 5 C = 100 + 10

Or, 5 C = 110

∴ C = $\dfrac{110}{5}$

i.e C = 22 years

So, The age of Chuck = C = 22 years

The age of Bob = 2 C = 2 × 22 = 44 years

The age of Susie = S = 2 C - 10

I.e The age of Susie = S = 2 × 22 - 10

Or, The age of Susie = S = 34 years

Hence, The age of Susie is 34 years . Answer
