Answer:

= 221

Step-by-step explanation:

Lenght = 250

Width= x

Perimeter = 2 (l+b) = 942

2 x (250 +x) = 942

500 + 2x = 942

2x = 942 - 500= 442

x = 442 /2  = 221

Answer:

he ate 12/12 which means the dinasour ate all of the plant

Step-by-step explanation:

i cant lie this is a wierd question cause it seems to obvious but here it is....

10/12+ 2/12= 12/12

12/12=1 whole the dinasour ate the entire plant

Answer: 10/12 + 2/12 = 12/12 or 1 whole

Step-by-step explanation: Since it says at first the dino ate 10/12 and then after it ate 2/12 more. When your adding fractions the denominator doesn't change but the numerator does. Therefore its basically saying what's 10+2 which = 12 then you put the denominator on the bottom which is 12/12 if you want to simplify it. It turns to a 1 whole

Answer:

Answer:

15

Step-by-step explanation:

if every $11 dollars he save $5, and sense he made $33 ( he done three babysitting)

11-5= 5 (does that three times) [5+5+5} when you add the three five , u should have 15 dollars.

so he save 15 dollars.

Answer and explanation:

Since Oscar charges $25 for the first hour and $15 for every additional hour or fraction of an hour, his function would be :

f(x)= 25x 0 is less than or equal to x and x is less than or equal to 1

Latoya charges $30 for the first three hours and $20 for every additional hour or fraction of an hour. The function :

f(x)= 30x

0 is less than or equal to x and x is less than or equal to 3

Given that each taught their students for 5.5 hours, their charges would be :

For Oscar,

The first hour = 25×1= $25

4.5 hours left= 15×4.5= $67.5

Total charge for 5.5 hours= $67.5+$25= $92.5

For Latoya,

The first three hours= 30×3=$90

2.5 hours left= 2.5×20= $50

Total charge for 5.5 hours= $90+$50= $140

Therefore Latoya will charge $47.5 more to tutor for 5.5 hours.

Answer:

The minimum number of miles you would need to drive in a month to make the first deal a better deal is 66.6 miles.

Step-by-step explanation:

For the first deal to be a better deal it has to cost less than the second plan and you can write an equation in which the first plan has a lower cost than the second one:

10+0.60m<0.75m, where:

m is the number of miles driven

Now, you can solve for m:

10<0.75m-0.60m

10<0.15m

10/0.15<m

m>66.6

According to this, the answer is that the minimum number of miles you would need to drive in a month to make the first deal a better deal is 66.6 miles.

Answer:

2x +5....................

The expression 2x + 5 represents the number of cards larry has.

An expression is a combination of some mathematical symbol such that arithmetic operator and variable such that all are constrained and create an equation.

For example 3x +5y

The constraint of expression is represented as = or <, >.

Given that,

Tashara has x number of baseball cards.

And,

Larry has 5 more than 2 times x

So,

Larry has = 2(x) + 5

Hence "The expression 2x + 5 represents the number of cards larry has".

Step-by-step explanation:

plus . minus and divide

Answer:

1- Let x = original price  then

x - .20x = 48

x(1 - .20) = 48

x(.80) = 48

x = 48/.80

x = $60

2-Let "x" be the number of lessons.

240 - 15x = 0

240 = 15x  

x = 16 lessons

3-divide equation by 2:

(2W-4) + W = 32

2W - 4 + W = 32

2W + W = 32 + 4

3W = 36

W = 36/3

W = 12 cm

Find the Length using L = 2W-4:

L = 2(12) - 4

L = 20 cm

Check: 2(20) + 2(12) = 64

4-P stands for the original price. The 90 stands for 90 %. Wendy paid 100-10, or 90 %.
