Answer:

Correct option: B -> (5 1/2) * 2

Step-by-step explanation:

We can observe the number of different distances she hiked:

5 1/4, 5 1/2, 6 1/4, 7 1/4, 7 1/2 and 7 3/4.

In Susannah's equation, we have only 5 parts, so it's missing one distance, that is 5 1/2.

In this distance there are 2 circles, so she hiked this distance two times. Then, the missing value that Susannah should sum is:

(5 1/2) * 2

Correct option: B

Tammy knits blanket and scarves. On the first day of a craft fair, she sells 2 blankets and 5 scarves for $104

omeli [17]

Answer:

Cost of Blanket = 32

Step-by-step explanation:

Let the cost of a blanket be = b , cost of a scarf be = s. Blanket price x Blanket Quantity & Scarf Price x Scarf Quantity sum up to be total sales.

So, Day 1 : 2b + 5s = 104 (i) , Day 2 : 3b + 4s = 128 (ii)

Solving equations : Multiplying (i) by 3 , & (ii) by 2 , we get

6b + 15s = 312 ,

(-)6b + (-)8s = (-)256

By elimination method, 15s - 8s = 312 - 256 → 7s = 56 → s = 56 / 7 = 8 .

Putting s value in any equation i], 2b + 5 (8) = 104 → 2b + 40 = 104 → 2b = 104 - 40 = 64 → b = 64 / 2 = 32

State what method you are using to solve the system. Then solve the system. Show all steps of your work, clearly state your answ

Anit [1.1K]

Answer:

The method used is substitution method

x = 2, y = -6

Step-by-step explanation:

Given the simultaneous equation

Y = −3x ..... 1

4x + y = 2 ... 2

Substitute equation 1 into 2

4x + (-3x) = 2

4x - 3x = 2

x = 2

Get y:

y = -3x

y = -3(2)

y = -6

<em>Hence the value of (x, y) is (2, -6)</em>

6. An air conditioning repair service call costs $75 per hour plus a flat fee trip charge of $25. If the situation can

Talja [164]

Answer:

THE ANSWER FROM YOUR OPTIONS IS:

(C) The repair charge r depends on the repair time h in hours.

Step-by-step explanation:

Repair-service call - $75 /hour

Flat fee trip-charge - $25

The function representing this situation: r(h) = 75h + 25

(A) Which is the dependent variable?

The dependent variable is the one whose value is to be gotten from the relationship between or among the values of other variables in the function. It usually appears at the left hand side of the equation. In this case, it is r(h).

(B) What do the variables represent?

The variables here - the algebra that can attain various values - are r and h.

r = total repair charges

h = repair time in hours [hence, if h = 1, repair time is 1 hour]

These are the two variables in this function.

r(h) now means repair charges in hours

THE ANSWER FROM YOUR OPTIONS IS:

(C) The repair charge r depends on the repair time h in hours.
