A 3. On a recent shopping trip, you see a sale advertising 4 pairs of socks and 3 pairs of shoes for $90. Write an equation using to represent the cost of socks and y to represent the cost of shoes.
A)40x + 30y - 90
B)30x + 40y = 90
C)3x + 4y - 90
D)4x + 3y = 90

Answers

The correct answer is D) 4x + 3y = 90.

x = pairs of socks
y = pairs of shoes
90 = total cost of the sum of socks and shoes

Combining these with the given quantities for each variable:

4x + 3y = 90

which inequality is true when the value of w is 13 w-<5 -w-3>-5 -w-3>5 w->5

Answers

w > -5 shows that w is greater than -5 and since 13 is greater than -5, hence the inequality expression w > -5 is true

We need to get the equation that is true for w to be 13. This means that the required inequality expression should be w must be a positive integer.

For the Expression -w - 3 > -5

-w > -5 + 3

-w > -2

w < 2

Since w is less than 2, hence the inequality is wrong

For the inequality

-w - 3 > 5

-w > 5 + 8

-w > 13

w < -13

Since w < -13, hence the inequality is wrong

For the inequality w > -5

It shows that w is greater than -5 and since 13 is greater than -5, hence the inequality expression w > -5 is true

Kadeem wants to ride his bicycle 52 miles this week. He has already ridden 16 miles. If he rides for 5 more days, write and solve an equation which can be used to determine xx, the average number of miles he would have to ride each day to meet his goal.
How to solve this for an equation.

Answers

The average number of miles that would be ridden to meet his goal is 7.2 miles.

Total distance = 52 miles

Distance ridden = 16 miles

Number of days left = 5 days

Let the number of miles that'll be ridden for each day be represented by x.

Therefore, the equation to solve the question will be:

5(x) + 16 = 52

5x + 16 = 52

5x = 52 - 16

5x = 36

x = 36/5

x = 7.2

Therefore, he'll have to ride 7.2 miles per day.

A diesel train left Abuja and traveled west.Two hours later a freight train left traveling 15 mph faster in an effort to catch up to it. After six hours the freight train finally caught up. Find the diesel train's average speed. (Need to have chart and explanation)

Answers

Step-by-step explanation:

let the speed of diesel train = x

the equation would be:

(2+6)x = 6(x+15)

8x = 6x+90

2x = 90

x = 90/2

x = 45

Therefore, the speed of diesel train =

Answer ja the first option . A

Pls help me with this​

Answers

Step-by-step explanation:

let's just write the equations on top of each other as in a large subtraction, then transform one of them so that at least one term is the range in both equations, and then do the subtraction.

a)

I automatically write rational numbers as the total fractions (14 1/4 = 57/4, 3 3/4 = 15/4)

15x - 7y = 57/4

- 5x - y = 15/4

15x - 7y = 57/4

- 15x - 3y = 45/4

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

0 -4y = 12/4

y = -(12/4)/4 = -12/16 = -3/4

then we use that in the simpler second equation

5x - -3/4 = 15/4

5x + 3/4 = 15/4

5x = 12/4

x = (12/4)/5 = 12/20 = 3/5

b)

we don't need to transform any equation, as the x terms are already equal.

3x - 4y = 2

- 3x - 7y = -1

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

0 3y = 3

y = 3/3 = 1

using this in e.g. the first equation

3x - 4×1 = 2

3x - 4 = 2

3x = 6

x = 6/3 = 2

I'll assume you are working with Excel.  The Product function multiplies all the cells given in the specified range.  Here, those are cells A2 through A5.  As presnted, this would be [10*5*0*(-7)] = 0, which is the value of cell B2.  If we want cell B2 to be -70, we must change one or more of the numbers in cells A2 to A5.

Change:  10, 1,  1, -7   B2 = -70

|x-1|+2<4 solving for x

Answers

Answer:

x < 3 and x > -1

Step-by-step explanation:

Step 1: Subtract 2 from both sides.

[tex]|x-1| + 2 - 2 < 4 - 2[/tex] [tex]|x-1|<2[/tex]

Step 2: Solve absolute value.

We know x - 1 < 2 and x - 1 > -2.

Condition 1:

[tex]x - 1 < 2[/tex] [tex]x - 1 + 1 < 2 + 1[/tex] (Add 1 to both sides)[tex]x < 3[/tex]

Condition 2:

[tex]x - 1 > -2[/tex] [tex]x - 1 + 1 > -2 + 1[/tex] (Add 1 to both sides)[tex]x>-1[/tex]

Therefore, the answer is x < 3 and x > -1.

Work out m and c for the line: 3 y + 6 x = − 3

Answers

Answer:

m is -2 and c is -1

Step-by-step explanation:

• Let's first phrase out the general equation of a line

[tex]{ \rm{y = mx + c}}[/tex]

m is the slopec is the y-intercept

[ remember that a general line equation must be in slope - intercept form as shown above ]

• from our question, we are given the equation;

[tex]{ \rm{3y + 6x = - 3}}[/tex]

• let's make y the subject in order to make the equation in slope - intercept format.

→ remember to apply "subject making knowledge"

[tex]{ \rm{3y = - 3 - 6x}} \\ \\ { \rm{3y = - 6x - 3}} \\ \\ { \rm{ \frac{3y}{3} = \frac{ - 6x}{3} - \frac{3}{3} }} \\ \\ { \boxed{ \rm{y = - 2x - 1}}}[/tex]

• The above boxed equation is now a general equation. Let's extract out slope, m and y-intercept, c

[tex]{ \rm{m \: \dashrightarrow \: - 2}} \\ \\ { \rm{c \: \dashrightarrow \: - 1}}[/tex]
