PLEASE HELP QUICK!!!!! Find the value of x

Answer:

3

Step-by-step explanation:

She only bought one chocolate so you will subtract 8.32 from her total, 27.79, when you do that you will get 19.47.  You do that so you can know the total of the stuffed animals by them self.  Then all you have left in the total is her stuffed animals so you divide 19.47 by 6.49, when you do that you get three, so that means that she got three stuffed animals.

Step-by-step explanation:

Answer:

Ito

Step-by-step explanation:

Make them to their closest common multiple which is twelve.

Next times 7 by 4 as 3*(4) is 12

Then time 9 by 3 as 3*(4) is 12

7*4=28

9*3=27

Therefore ito washes at a faster rate

Answer:

ITO

Step-by-step explanation:

ITO

He can wash 7 cars in 3 hours.

a) 3 x 60 min = 180 minutes

b) 180\7 = 25.71 minutes per car

JOAN

She can wash 9 cars in 4 hours

a) 4 x 60 = 240 minutes

b) 240\9 = 26.66 minutes per car

The Answer is: y=2,5

Answer:

y = -5

y = 2

Step-by-step explanation:

Find 2 factors of -10 that add up to 3

This will be 5 and -2

So, we can factor this:

y² + 3y -10 = 0

(y + 5)(y - 2) = 0

Set each factor equal to 0 and solve:

y + 5 = 0

y = -5

y - 2 = 0

y = 2

So, the solutions are y = -5 and y = 2

Step-by-step explanation:

Answer: dark chocolate 16/25 carmel 1/12

Step-by-step explanation:

there are 16 dark chocolates

to find the probability you have to add up all of your numbers

2+7+16= 25

so the probablity of drawing a dark chocolate is 16/25

repeat the steps but subtract 1 from the total since you ate one you didn't put it back.  

so the probability of drawing a carmel is 2/24 or simplified 1/12

=================================================

Explanation:

x = amount of the 95% concrete mix

y = amount of the 80% concrete mix

Type A mix has 95% concrete. If we have x pounds of this, then 0.95x pounds is pure concrete. Type B mix has 80% concrete. If there are y pounds of this, then 0.80y pounds is pure concrete.

So far we have 0.95x+0.80y pounds of pure concrete from the two mixes

Divide this over 30 to get (0.95x+0.80y)/30

Setting this equal to 0.90 means we want the final mix to be 90% concrete.

Since we want 30 pounds total, we can say x+y = 30 which solves to y = 30-x. We'll use this later

-------------------------------

(0.95x+0.80y)/30 = 0.90

0.95x+0.80y = 30*0.90 .... multiply both sides by 30

0.95x+0.80y = 27

0.95x+0.80(30-x) = 27 ..... plug in y = 30-x

0.95x+0.80*30-0.80*x = 27

0.95x+24-0.80x = 27

0.15x+24 = 27

0.15x = 27-24 ..... subtracting 24 from both sides

0.15x = 3

x = 3/0.15 ........... dividing both sides by 0.15

x = 20

y = 30-x

y = 30-20

y = 10

Answer:

60

Step-by-step explanation:

12 ÷ (3 - 1) = 6

6 + 4 = 10

10 × 6 = 60

Answer:

This means that 1cm on the map means 10miles on actual land so is it the same for 30miles

That is 1cm on map 30 cm on land

Answer:

62/78*( 1 6/8)

= 31/39*( 1 6/8)

= 31/29*( 1 3/4 )

= 31/39* 7/4

Multiply the numerator together and the denominator together

= 217/156

Answer:

Step-by-step explanation:

First of all cross multiply

That's

g( wd + f ) = a + bc

Multiply the terms at the left side of the equation

We have

gwd + fg = a + bc

Send fg to the right side of the equation

That's

gwd = a + bc - fg

Divide both sides by dg to make W stand alone

We have the final answer as

Any real value to the power of 0 is 1.

Answer:

2(x+16)

Step-by-step explanation:

it says product of 2 means 2 times

then it says sum of x and 16 so thy are asking for the sum of x and 16 then multiplied by 2

so the ans is 2(x+16)

Answer: Integers

Step-by-step explanation: To help introduce the set

of integers, let's use the number line shown below.

Notice that on a number line, 0 is in the middle, all numbers to the

left of 0 are negative, and all numbers to the right of 0 are positive.

The set of integers includes the set of whole numbers, {0, 1, 2, 3, ...},

which appear at 0 and to the right of 0 on the number line.

The set of integers also includes {-1, -2, -3, ...} which

appear to the left of 0 on the number line.

So the ste of integers can be written as {...-3, -2, -1, 0, 1, 2, 3...}.

Answer:

Integers

Step-by-step explanation:

a positive (+) or negative (-) number with no fractional parts. zero (0) Is also an integer

Examples: -3, 3

Answer:

Option (C) and (D)

Step-by-step explanation:

Given piecewise function is,

f(x) = 2x, x < 1

        5, x = 1

        [tex]x^{2}[/tex], x > 1

Option (A),

x = 5 means x > 1

So the function will be,

f(x) = [tex]x^{2}[/tex]

f(5) = (5)²

     = 25

Therefore, f(5) = 1 is not correct.

Option (B),

x = -2 means x < 1

f(x) = 2x will be applicable.

f(-2) = 2(-2) = -4

Therefore, f(-2) = 4 is not correct.

Option (C)

For x = 1,

f(1) = 5

Therefore, f(1) = 5 is the correct option.

Option (D)

x = 2 means x > 1 and the function defined will be,

f(x) = x²

f(2) = 2²

     = 4

Therefore, f(2) = 4 will be the correct option.

Options (C) and (D) will be the answer.

Answer:

19

Step-by-step explanation:

Given

(6 + h² - j) ÷ 2 , substitute h = 6 and j = 4 into the parenthesis

= (6 + 6² - 4) ÷ 2

= (6 + 36 - 4) ÷ 2

= 38 ÷ 2

= 19

Answer:

There is no value of x that will make this true
