Answer:

x=1.8

Step-by-step explanation:

To solve this equation, we can use PEMDAS and the various properties.

First, use the distributive property on all parenthesis, since parenthesis come first.

4x-1+6x+6x+24=52

Now we can use the commutative property to add all like terms.

16x+23=52

Now just subtract on both sides.

52-23=29 so our equation is 16x=29

To isolate x, divide both sides by 16.

x=1.8 rounded up

Hope this helps!

Paolo is buying salad and pizza for a company lunch. Suppose that a bowl of salad costs $5.00, and slice of costs $2.00.Let E be
Slav-nsk [51]

Answer:

  • E=5S+2P
  • P=0.5(E-5S)

\left|\begin{array}{c|c|c}$Budget (Dollars)& $Salad (Bowls) &$Pizza (Slice)\\40.00&0&20\\40.00&4&10\\40.00&8&0\end{array}\right|

Step-by-step explanation:

Cost of a bowl of salad = $5.00

Cost of a slice of pizza = $2.00

If Paolo buys S bowls of salad and P slices of pizza, then the total amount of money he spends E can be represented by the equation:

  • E=5S+2P

Next, we make P the subject of the equation above.

2P=E-5S

P=\dfrac{E-5S}{2} \\P=0.5(E-5S)

Therefore, The quantity of pizza he buys can be represented by the equation:

  • P=0.5(E-5S)

When E=$40, we are required to complete the table below.

\left|\begin{array}{c|c|c}$Budget (Dollars)& $Salad (Bowls) &$Pizza (Slice)\\40.00&0&\\40.00&4&\\40.00&&0\end{array}\right|

When S=0, E=$40

From P=0.5(E-5S)

P=0.5(40-5(0))=20

When S=4, E=$40

P=0.5(40-5(4))

=0.5(40-20)

=0.5*20

=10

When P=0, E=$40

P=0.5(E-5S)

0=0.5(40-5S)

40-5S=0

5S=40

S=8

Therefore, the completed table is:

\left|\begin{array}{c|c|c}$Budget (Dollars)& $Salad (Bowls) &$Pizza (Slice)\\40.00&0&20\\40.00&4&10\\40.00&8&0\end{array}\right|

a school debate team has 4 girls and 6 boys. a total of 4 of the team members will be chosen to participate in the district deba
alexgriva [62]
The correct question is:
What is the probability that 2 girls and 2 boys will be selected?

Solution:
Total number of students = 10
Ways to select a team of 4 students = 10C4 = 210

2 Boys can be selected from 6 boys in ways = 6C2 = 15
2 Girls can be selected from 4 girls in ways = 4C2 = 6

Number of ways to select 2 boys and 2 girls = 15 x 6 = 90

Probability of choosing 2 boys and 2 girls = 90/210 = 3/7

Thus, if 4 team members are selected, the probability of choosing 2 boys and 2 girls will be 3/7
