Total no. Ratio
Ride the bus x. = 3
Total. 24 8 This creates a proportion where both fractions: x/24 and 3/8 are equivalent fractions.

Cross multiply: 8x = (3)(24)
Multiply: 8x = 72
Divide both sides by 8: 8x/8 = 72/8
Divide: x = 9 <—. The number of students who ride the bus

I need to factor 2x squared plus 6X minus 80
hjlf
2x*2 + 6x + 80

First we have to use distribution property

2(x*2 + 3x + 40)=0
Divide 2 to both sides

X*2 + 3x + 40=0

Multiply -1
-x*2 -3x-40=0
Add two numbers to get 3x
Multiply same two numbers that you add to get 40x*2

Add
-8x+5x= -3x


Multiply
-8x . 5x= -40x*2


-x*2-8x+5x-40

(X*2-8x) + (5x-40)

X(x-8)+ 5(X-8)

Common factor

(X-8)(x+5)

We are planning a reception for our daughter. The hall that we are renting charges $55 clean up fee. In addition to the cleanup
elena55 [62]

Answer:

89 is  the maximum number of guests that can be invited within budget  .

Step-by-step explanation:

The cleaning charges = $55

Total budget available = $3350

Cost per guest = $37

Now, actual budget available for guest = Total budget -  Cleaning Fee

= $3350  - $ 55   = $3,295

Now, cost per head =$ 37

So, number of guests (n) possible in the budget

⇒ n = (Total guest Budget)/ Cost per head

= $3,295 / $37  = $89.05

or,  n = $89.05

So, 89 is  the maximum number of guests that can be invited within budget  .

On Monday, Mr. Roberts drove 42 miles. On Tuesday, he drove 5 miles more than half the distance he drove on Monday. Which expres
butalik [34]

Answer: Last option

(42÷2) +5

Step-by-step explanation:

We know that Mr. Roberts drove 42 miles on Monday.

On Tuesday Mr. Roberts drove half of what he drove on Monday plus 5 miles.

If we want to know how many miles Mr. Roberts drove on Tuesday then we should divide 42÷2 to find half of 42.

\frac{42}{2} = 21

Then we know that in addition to the 21 miles he drove 5 more miles. Then we add 21 +5 = 26 miles.

So the expression that gives us the number of miles that Mr. Roberts drove on Tuesday is:

(42÷2) +5
