Answer:

  (c)  24 minutes

Step-by-step explanation:

The rate of working problems differs by ...

  (1 problem)/(1.5 minutes) - (1 problem)/(2 minutes)

  = (2/3 -1/2) problems/minute

  = 1/6 problems per minute

So, to make up the difference of 4 problems will take ...

  time = quantity/rate = (4 problems)/(1/6 problem/minute) = 24 minutes

Caroline and Chase will be on the same problem after 24 minutes.

_____

Additional comment

Technically speaking, Chase will just be finishing problem 26 when Caroline starts it after 19.5 minutes. At that point in time, they are on the same problem. The answer choices suggest the real question is, "after how many minutes will they be starting the same problem at the same time?" After 24 minutes, both will be starting problem 29 at the same time.

2.d

Step-by-step explanation:

1.6(3x + 5) = 18x + 30 = 15x + 30 + 3x.

SO, the ? is equal to 30.

2. d

Step-by-step explanation:

√3sinA-cosA=√2

dividing both side by (√3²-1²=2 we get)

√3/2 sinA-1/2.cos A=√2/2

cos 30sinA-sin30cosA=√2/(√2×√2)

sinAcos30-cosAsin30=1/√2

sin(A-30)=sin45,sin(180-45)

therefore

A-30=45,135

A=45+30=75 or A=135+30=165

Answer: 9

Step-by-step explanation:

The required -360 divided by -40 is equal to 9. The negative signs cancel out when dividing two negative numbers, resulting in a positive result.

When dividing two negative numbers, it's helpful to keep in mind the following rule:

The division of two negatives yields a positive result.

Now, let's perform the division:

-360 ÷ -40

Since both numbers are negative, we know the result will be positive.

Divide the absolute values of the numbers.

|-360| ÷ |-40| = 360 ÷ 40 = 9

Apply the rule for the division of two negatives.

Since both numbers are negative, the result will be positive:

-360 ÷ -40 = 9

Therefore, -360 divided by -40 is equal to 9.

The expressions are simplified and factored in as below.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

The expressions are simplified as,

1.

5x + 3x

= 8x

7x + 2x + 4

= 9x + 42

11.

18x + 3x + 9

= 21x + 9

12.

6x + x + 8

= 7x + 8

13.

21x + 15y

= 3(7x + 5y)

14.

2x + 14y

= 2(x + 7y)

15.

15x + 10y

Answer:

4.125 in decimal form and 4 1/8 in simplified fraction form

Step-by-step explanation:

The value of multiplication of an improper fraction 3/8 and a whole number 11 as a mixed number is 4 1/8.

To calculate 3/8 × 11 as a mixed number, we can follow these steps:

Step - 1:

Multiply the whole number by the numerator of the fraction:

11 × 3 = 33

Step - 2:

Divide the result by the denominator of the fraction:

33 ÷ 8 = 4 with a remainder of 1

Step - 3:

The whole number part of the mixed number is the quotient from the division:

The whole number part is 4.

Step - 4:

The fractional part of the mixed number is the remainder divided by the original denominator:

The fractional part is 1/8.

Therefore, the answer to 3/8 × 11 as a mixed number is 4 1/8.

Answer:

y= 3x +1

Step-by-step explanation:

Slope-intercept form:

y= mx +c, where m is the slope and c is the y-intercept.

Gradient= [tex] \frac{y1 - y2}{x1 - x2} [/tex]

☆ (x1, y1) is the 1st coordinate and (x2, y2) is the 2nd coordinate

Using the formula above, slope of line

[tex] = \frac{19 - 7}{6 - 2} \\ = \frac{12}{4} \\ = 3[/tex]

Subst. m=3 into the equation:

y= 3x +c

To find the value of c, substitute a pair of coordinates.

When x= 2, y= 7,

7= 3(2) +c

7= 6 +c

c= 7 -6

c= 1

Thus, the equation of the line is y= 3x +1.
