The city contributed $13,500; the county contributed $27,000; and the state contributed $54,000.

Let x be the amount the city contributes.  Since the county contributes twice as much as the city, the county's amount is 2x.  Since the state contributes twice as much as the county, the state's amount is 2(2x) = 4x.

They total 94,500:
x+2x+4x = 94500
7x = 94500

Divide both sides by 7:
x = 13500
2x = 27000
4x = 54000

Tawana has $325.54 in her checking account. She must keep a balance of at least $300 to avoid a fee. She plans to write a check
den301095 [7]

Answer: To pay her bill with the minimum balance to avoid the fee, she needs the total amountof $300+$125.43=$425.43. But she only has $325.54. So, the extra minimum amount she needs to deposit is 425.43-325.54=$99.89.

Hence, the answer is $99.89.

Step-by-step explanation:

From the question, we are told that a recipe call for 3/4 c of chopped pecans

and that Brentt wants to triple the recipe .

The numerical expression that represents the amount of pecans he will need will be gotten by multiplying 3/4c by 3. This will be:

= 3 × 3/4c

= 9/4c

= 2 1/4

Solve for x: −2x + 5 &lt; 7 <br> Please Help Meh!! DO you LIKE to see people STRUGGLE?!?!
Arlecino [84]

x > -1


-2x+5 < 7

-2x<2

Now since you divide by (-1) to get positive 2,you need to flip the sign

(-2)/(-1)= 2     2/(-1)=-2

SO

2x>-2

x > -1

To check  the solution do not replace the x by -1 because it shouls be more than -1  (You can choose 0,1,2,3....)

Example  choose x=3

-2x3+5<7

-6+5<7

-1<7

Aysha has 40 cubes in a bag.
marissa [1.9K]

Given:

Total number of cubes = 40

Red cubes = 18

Blue cubes = 13

Yellow cubes = 9

Aysha adds some more red cubes into the bag.

The probability now that she will take a red cube is 0.5.

To find:

The probability that she will take a yellow cube.

Solution:

Let Aysha adds x red cubes into the bag. Then,

Number of total cubes = 40+x

Number of red cubes = 18+x

Probability of getting a red cube is:

P(Red)=\dfrac{18+x}{40+x}

The probability now that she will take a red cube is 0.5. So,

\dfrac{18+x}{40+x}=0.5

18+x=0.5(40+x)

18+x=20+0.5x

x-0.5x=20-18

0.5x=2

Divide both sides by 0.5.

x=\dfrac{2}{0.5}

x=4

It means Aysha adds 4 more red cubes into the bag.

Now, the total number of cubes int he bag is:

40+4=44

Probability of getting a yellow cube is:

P(Yellow)=\dfrac{\text{Number of yellow cubes}}{\text{Total number of cubes}}

P(Yellow)=\dfrac{9}{44}

Therefore, the required probability is P(Yellow)=\dfrac{9}{44}.
