Answer:

1.)  C. 2 Pages

2.) B. 76 mph

3.) C. 35 cents

4.)?

5.)?

6.)B

7.) B

Step-by-step explanation:

1. 2 1/2 = 5/2              1 1/4 = 5/4         5/4 * 4/5 = 1    so it is a unit with one

5/2  *  4/5 = 4/2   or 2              (You found unit by multiply what you did to the unit, because what you do to one side you do to the other)

2. 3 1/2 = 7/2     7/2 * 2/7     7/2 = 266    multiply for unit price, other wise you don't know what the true mph is, now multiply the 266 by 2/7 because what you do to one side you do to the other

2/7 = 266/1      multiply numerators and denominators

2 * 266 = 532

7 * 1 = 7             now put it back as a fraction

532/ 7          simplify

532/7 = 76

76 mph

3. 1.75 = 1 3/4 = 7/4           7/4 = 5       price = bagels       now multiply the 5 by 1/5 (reciprocal) so that you can figure out what the unit is

5 * 1/5 = 1

7/4 * 1/5         multiply numerators together and denominators together

7 * 1 = 7

4 * 5 = 20

7/20 = .35

35 cents

4. 5.  I am not sure

6.  Solve each of them

A. 12 6/10 =126/10      126/10 = 7         multiply both for 1/7  for unit price

7 * 1/7 = 1           126/10 * 1/7      multiply   126 * 1 = 126     10 * 7 = 70

126/70 = 1.80

B.  10.98 = 1098/100  1098/100 = 6/1        

1098/100 * 6/1         Multiply so that the unit is right

1098/600 = 1.83

1.83 = 1 juice

C. 18.10 = 18 1/10 = 181/10 181/10 = 10      price = number of juice

181/10 * 1/10 = 181/100               multiply with 1/10 so that 10 is 1 (unit price)

$1.81 = 1 juice

D.   16 38/100 = 1638/100    1638100 = 9   multiply both sides by 1/9 so unit is 1

9 * 1/9 = 1

1638/ 100 * 1/9    1638/900  =  1.82

$1.82 = 1 juice

1.80 per juice is cheapest so it is B

7.

B. 1 = $5   it is the unit so if you multiply by all the numbers on top it will equal the number in the row, none of the others do that

Need Help Badly<br>What is the solution
Kamila [148]
Sqrt(1-3x)=x+3
[sqrt(1-3x)]^2=(x+3)^2
1-3x=(x+3)(x+3)
1-3x=x^2+6x+9
-3x=x^2+6x+8
0=x^2+9x+8

The answers are -1 and -8 BUT, we have to plug them back into the original equation to make sure we don't get a negative under the square root sign.

After doing this, we realize that only -1 works, so the answer is x=-1

Sorry that this took forever to answer. I was thinking of a good way to explain this, and if you need any further explanation, message me:)

Best wishes:)

Bottles of sparkling water usually cost $1.69 each. This week they are in sale for 4 for $5. You bought one last week and one th
Phantasy [73]

Answer:

The cost of 1 sparkling bottle in this week is less than last week, so we pay less this week.

We pay $0.44 less this week.

Step-by-step explanation:

Given,

Cost of 1 sparkling bottle last week = $1.69

This week cost of 4 bottles is $5.

So we have to find the cost of 1 bottle.

For this we use the unitary method, we get the cost of 1 bottle;

Cost of 1 sparkling bottle this week = \frac{5}{4}=\$1.25

The cost of 1 sparkling bottle in this week is less than last week, so we pay less this week.

For finding how much we pay less this week, we have to subtract cost of 1 sparkling bottle this week from cost of 1 sparkling bottle last week.

Framing the above sentence in equation form, we get;

Amount\ of\ money\ we\ pay\ less=1.69-1.25=\$0.44

Hence we pay $0.44 less this week.

Amy hikes down a slope to a lake that is 10.2 meters below the trail. Then Amy jumps into the lake, and swims 1.5 meters down. S
Grace [21]

she went down the slope 10.2 meters, -10.2

then she jumped down to the lake 1.5 meters, -1.5

-10.2 - 1.5 = -11.7 meters.

so she pretty much went 11.7 meters down from her original location.
