Answer:

5

Step-by-step explanation:

cross multiply

isolate x

12x=7.5(8)

12x=60

12x/12=60/12

5 is the answer

Answer:

Option 4

Step-by-step explanation:

Thank me later

Answer:

Step-by-step explanation:

In written form:

three hundred fourteen thousandths

In standard form:

0.314

In expanded form:

3 x (1/10) + 14 x (1/1000)

3 x (1/10) = .3

14 x (1/1000) = .014

.3 + .014 = .314

Therefore, these are the two correct answer choices.

He made a mistake on the First step I think

Step-by-step explanation:

1st one

Answer:

First mistake appears in First Step

Step-by-step explanation:

First mistake appears in First Step, within the parenthesis need to solve division first.

2 + 5 x (4 + 18 ÷ 6)

Step 1 should be 18 ÷ 6

2 + 5 x ( 4 + 3 )

Step 2 is 4 + 3

2 + 5 x 7

Step 3 is 5 x 7

2 + 35

Step 4 is 2 + 35

good luck! have a nice day!

Steps:

Step 1: Simplify both sides of the equation.

4x+3=9

Step 2: Subtract 3 from both sides.

4x+3−3=9−3

4x=6

Step 3: Divide both sides by 4.

4x /4  =  6 /4

Answer: x= 3/2

Step-by-step explanation:

Answer:

a) y=(300-150)x-2100

b) y=150x-2100

c) y=150(140)-2100

y=18900

Jose was wrong. He did not make 20000 dollars last year.

Answer:

A: ((300-150) * 140) - 2100

B: 21000-2100= $18,900 profit.

Jose made 18,900 dollars worth of profit. He did not make $20,000 worth of profit.

Answer:

Given below

Step-by-step explanation:

M is Mikey and B is Betty in,

Current ages:

M= x

B= 3x (cuz she is 3 times older)

After 5 years

M= x+5

B= 3x+5 (5 years added to present age)

It says the ages of Betty after 5 years (3x+5) will be twice as much as Mikey (2(X+5))

So,

3x+5 = 2(x+5)

3x+5 = 2x+10

3x -2x = 10-5

x = 5

Therefore,

The current ages are

Betty : 3x = 3*5 = 15

Mikey: 5 (x)

You can verify by checking with the criterias or clues given in the question.. hope this helps..mark as brainiest if this was helpful:)

Answer: The current ages are

Betty : 3x = 3*5 = 15

Mikey: 5 (x)

The time is not limited to rational numbers or integers. Natural numbers are a subset of integers. So the domain is positive real numbers.

Answer:

k=29

Step-by-step explanation:

(5K-3)+(9+k)=180

6k+6=180  add like numbers

6x=174        subtract 6 from 180

x=29           divide by 6

The solution is : k=29, is the value of k.

Addition is a way of combining things and counting them together as one large group. ... Addition in math is a process of combining two or more numbers.

Here, we have,

from the given diagram, we get,

(5K-3)+(9+k)=180

6k+6=180     [add like numbers]

6x=174       [ subtract 6 from 180]

x=29          [ divide by 6]

Hence, The solution is : k=29, is the value of k.

Answer:

B. 7x-5 = 11

Step-by-step explanation:

you're putting -5 instead y in equation 7x+y = 11 so 7x+(-5) =11

Answer:

3) The function's leading coefficient is negative.

Explanation:

(1) Is not the answer because when x = 3, f(x) = 0.

(2) Is not the answer because when f(x) = -3,

x = 0.

(4) Is also not the answer because the y-values on both sides of (1, -4) are mirroring each other.

Therefore,

(3) is the answer, by elimination, but also because there is not proof of the leading coefficient being negative, as we don't see the original equation.

I hope this helped! :)

Answer: 36

The LCM of 2, 3, 4, 5, 6, 7, 8, 9, 10 and 11 is 2 × 3 × 2 × 5 × 7 × 2 × 3 × 11 = 27720.

A multiple of 27720 will end in 0, and the sum of its digits will be a multiple of 9.

The largest 6-digit number which is multiple of 9 with last digit of 0 is 999990, and the sum of its digits is 45. 45 is not a multiple of 27720, and there is no other way to get a digit sum of 45.

We now look at the next biggest multiple of 9, 9 × 4

= 36.

The largest 6-digit multiple of 27720 is 27720 × 36 = 997920, and the sum of its digits is 36.

Answer:

C

Step-by-step explanation:

Because the x line is for degrees C and the y is for Degrees F and the y intercept is where C is at 0 and F is at 32 making it the temp in F when C is at 0 degrees

Answer:

see below

Step-by-step explanation:

sqrt( -6) * sqrt(-24)

We know that sqrt(a b) = sqrt(a) sqrt(b)

sqrt(6) sqrt(-1)  * sqrt(24) sqrt(-1)

We know that sqrt(-1) = i

sqrt(6) i  * sqrt(24) i

We know that sqrt(a) sqrt(b) = sqrt(ab)

sqrt(6*24) i*i

sqrt(144) i^2

12 i^2

We know that i^2 = -1

12 (-1)

-12

Answer: It means that there are 570 chocolate chips in all the 30 cookies

Step-by-step explanation:

The mean also referred to as the average of a data set is calculated by adding all numbers in a data set and dividing by number of values in the set.

Since the mean number of chocolate chips in 30 cookies is 19 chocolate chips, this means that there are:

= (30 × 19) = 570 chocolate chips in the cookies.

Answer:

19b-4

Step-by-step explanation:

7b+3(4b-2)+6÷3

Bracket comes first so we distribute 3 over the terms in the bracket

= 7b + 12b -6 +6 ÷ 3

First we solve division

= 7b + 12b -6 +6 ÷ 3

= 7b + 12b -6 +2

= (7b+12b)+(-6+2)

= 19b -4

This can't be simplified further as it can't be solved anymore

Answer:

19b - 4

Step-by-step explanation:

Distribute the 3 to (4b - 2), like so:

3(4b - 2)

12b - 6

→ 7b + 12b - 6 +6 ÷ 3

Add like terms:

→19b - 6 + 6 ÷ 3

Following PEMDAS, you divide 6 by 3 first:

→19b - 6 + 2

Add like terms:

→19b - 4

Answer:

H≤7

Step-by-step explanation:

Answer:

x = 18

Step-by-step explanation:

Given

[tex]\frac{3x}{5}[/tex] + 1 = [tex]\frac{4x}{15}[/tex] + 7 ( subtract 1 from both sides )

[tex]\frac{3x}{5}[/tex] = [tex]\frac{4x}{15}[/tex] + 6

Multiply through by 15 to clear the fractions

9x = 4x + 90 ( subtract 4x from both sides )

5x = 90 ( divide both sides by 5 )

x = 18
