Answer:

37

Step-by-step explanation:

If you do the reverse equation, that is -72 divided by -4 which gives you 18. Then you add 19 to that 18 and you get 37.

Answer:

the answer is 37

Step-by-step explanation:

37 - 19 = 18

18 x -4 = -72

Answer:

-2 is the y intercept

Step-by-step explanation:

this is because it is in the y=mx+b format so 5x=mx therefore b=-2 making -2 the y intercept

Answer:

Step-by-step explanation:

The y intercept is the value where x = 0

y = 5(0) - 2

The y intercept is (0,-2).

The best way to confirm this is to graph it. Use Desmos.

Answer:36

Step-by-step explanation:

The required first and smallest term of consecutive terms is 38.

Given that,

The average of five consecutive numbers is 38. The smallest number to be determined.

The average of the values is the ratio of the total sum of values to the number of values.

The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.

The average of five consecutive numbers is 38.
Let the middle value is a,
Series of 5 number can be given as = (a -2n) , (a-n) , a , (a+n) , (a+2n).
n = 5
Average = ( a-2n +a -n + a +a+n+ a+2n)/5
38 = 5a/5
a = 38
Now smallest and first term (n = 1)   = a - 2n
                                                     = 38 - 2(1)
                                                     = 36

Thus, the required first and smallest term of consecutive terms is 38.

Answer:

clockwise, 90°

(0, 0)

Step-by-step explanation:

Draw a segment from (0, 0) to (1,1).

After the rotation, that segment becomes a segment from (0, 0) to (1, -1).

the rotation is 90° clockwise, and the point it is rotated about is (0, 0).

Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.

Take the reciprocal of the second fraction by flipping the numerator and denominator, leaving the negative sign on the numerator, and changing the operation to multiplication. Then the equation becomes

For fraction multiplication, multiply the numerators and then multiply the denominators to get

Two terms between the 1st and the 4th in the given geometric sequence is 21 and 147.

The formula for the nth term in a geometric sequence is given by:

a(n) = a(1) . rⁿ⁻¹

Where:

a(1) = first term

r = common ratio

Parameters given:

a(1) = 3

a(4) = 1029

Substitute n  = 4 into the formula:

a(n) = a(1) . rⁿ⁻¹

a(4) = 3 . r³

1029 = 3 . r³

r³ = 1029/3 = 343

r = 7

Two terms between the 1st and the 4th term is a(2) and a(3).

In a geometric sequence, the following applies:

a(n) = a(n-1) . r

Hence,

a(2) = 3 . r

       = 3 . 7 = 21

a(3) = a(2) . r

       = 21 . 7 = 147

Answer:

Slope shows that she is consistently burning 10 calories per minute

Step-by-step explanation:

Answer:

3.5 hours

Step-by-step explanation:

Let us represent

The time spent walking as x

The time spent riding as y

Jim began a 146​-mile bicycle trip to build up stamina for a triathlete competition.​ Unfortunately, his bicycle chain​ broke, so he finished the trip walking. The whole trip took 5 hours.

Hence:

x + y = 5.... Equation 1

x = 5 - y

If Jim walks at a rate of 4 miles per hour and rides at 40 miles per​ hour,

The formula for Distance = Speed × time. Hence,

4 × x + 40 × y = 146 miles

4x + 40y = 146.... Equation 2

We substitute 5 - y for x in Equation 2

4(5 - y) + 40y = 146

20 - 4y + 40y = 146

Subtract 20 from both sides

20 - 20 - 4y + 40y = 146 - 20

- 4y + 40y = 146 - 20

36y = 126

y = 126/36

y = 3.5 hours

Since the time he spent raiding his bicycle is represented by "y", the amount of time he spent on the bicycle is 3.5 hours

Answer:

-1.5

Step-by-step explanation:

3/8 is 0.375 in decimal form

Answer:

-1.5

Step-by-step explanation:

The probability is 7/5.

A person is randomly selected from a group of 1000 people.

We have,

440 people use glasses and must wear them.

20 wear glasses but are not required to do so.

140 people who should wear glasses but don't

400 if you don't need to wear glasses, don't wear them.

Therefore, the probability that the person does not wear glasses while driving even though he or she needs to wear them is:

P ( he or she does not wear glasses and needs to wear them / Total number of people surveyed ) = 140 / 100

P = 14 / 10

P = 7 / 5

The probability that he or she drives without wearing eyeglasses despite the fact that they are required is 7 in 5.

the length of side OP of rhombus is 45 mm and PM + MN is equal to 90 mm.

We are given a rhombus MNOP

We know that, a rhombus is a quadrilateral in which there are 4 sides and all the sides are equal.

We are given the length of the side NO as:

NO = 45 mm

Now, we need to find the length of side OP.

OP = 45 mm ( as NO = OP)

Also, we need to find PM + MN

PM + MN = NO + NO ( as PM = MN = NO )

= 2 NO

= 2 × 45 mm

= 90 mm

Therefore, we get that, the length of side OP of rhombus is 45 mm and PM + MN is equal to 90 mm.
