Martina drove 792 miles in 11 hours.
At the same rate, how long would it take her to drive 504 miles?

Answers

Answer 1

Answer:

7 hours

Step-by-step explanation:

Her rate (speed) is

v = d/t = (792 miles) / (11 hrs) = 72 mph

To drive a distance D = 504 miles, it will take her a time T given by

T = D/v = (504 miles) / (72 mph) = 7 hours

O x=35
O x= -25
O x= 25
O x=35

Answers

Hey there!

2/7(x + 4) = -6

2/7(x) + 2/7(4) = -6

2/7x + 8/7 = -6

SUBTRACT 8/7 to BOTH SIDES

2/7x + 8/7 - 8/7 = -6 - 8/7

CANCEL out: 8/7 - 8/7 because it gives you 0

KEEP: -6 - 8/7 because it helps solve for the x-value

NEW EQUATION: 2/7x = -6 - 8/7

SIMPLIFY IT!

2/7x = -50/7

MULTIPLY 7/2 to BOTH SIDES

7/2 * 2/7x = 7/2 * (-50/7)

CANCEL out: 7/2 * 2/7 because it gives you 1

KEEP: 7/2 * (-50/7) because it helps solve for the x-value

NEW EQUATION: x = 7/2 * (-50/7)

SIMPLIFY IT!

x = -25

Therefore, your answer is: x = -25

Please help. What is the slope for #2?

Answers

Answer: -4

Step-by-step explanation:

To find the slope, you want to use the slope formula [tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]. You can use any two points to solve. Let's use (-2,3) and (-1,-1).

[tex]m=\frac{-1-3}{-1-(-2)} =\frac{-4}{1} =-4[/tex]

Another way to tell is by looking at the arrows with a -4 written next to it. That also tells you what the slope is.

Solving system of equations

Answers

im assuming you meant 2x + y = 6 instead of 2x = y = 6

answer:
x = 14/3
y = -10/3

step by step explanation:
2x + y = 6
x + 2y = -2
solve for y in the first equation
y = 6 - 2x
plug y into the second equation
x + 2(6 - 2x) = -2
-3x + 12 = -2
-3x = -14
x = 14/3
plug into the y equation
y = 6 - 2(14/3)
y = -10/3

A clothing store features Shirts and Pants in the ratio of 3:6. There are 42 more Shirts than pairs of pants. How many articles of clothing are in the store?

Answers

Answer:

126

Step-by-step explanation:

The ratio of shirts to pants = 3:6. Which also equals 1:2.

Let the pairs of pants = t

Since there are 42 more shirts than pair of pants, shirts = t + 42

Number of pairs of pants is t.

Number of shirts = (t + 42)

The number of the pairs of pants is 42.

The number of shirts is 84.

Total number of clothings is 126.

Write 6.384 to 1 decimal place

Answers

Answer:

6.384 rounded to one decimal place is 6.4

Step-by-step explanation:

The number rounded to one decimal place is 6.4.

What is rounding off a number?

To change a number into an approximation having fewer significant digits.

Given that, 6.384 to 1 decimal place,

Rounding 6.384 to one decimal place would be the same as rounding it to the nearest tenth.

The tenth in this number is 3. To round a number up, look at the number to the right of it - if the number is 5 or greater, then you increase the value of the number you're rounding by 1. If the number to the right of it is 4 or less, then the value of the number you're rounding stays the same.

In this case, the number we're rounding is 3 and the number to the right of it is 8. Since 8 is greater than 5, we have to increase the value of 3 by 1, which means that the number in the tenths position is now 4.

Hence, The number rounded to one decimal place is 6.4.

Answer:

5. x = 13

6. x = 11; y = 3

Step-by-step explanation:

5. (9x + 2)° = 119° (alternate interior angles are congruent)

[tex] 9x + 2 = 119 [/tex]

Subtract 2 from each side

[tex] 9x + 2 - 2 = 119 - 2 [/tex]

[tex] 9x = 117 [/tex]

Divide both sides by 9

[tex] \frac{9x}{9} = \frac{117}{9} [/tex]

[tex] x = 13 [/tex]

6. (9x + 25)° = (13x - 19)° (corresponding angles are congruent)

[tex] 9x + 25 = 13x - 19 [/tex]

Collect like terms

[tex] 9x - 13x = - 25 - 19 [/tex]

[tex] -4x = -44 [/tex]

Divide both sides by -4

[tex] \frac{-4x}{-4} = \frac{-44}{-4} [/tex]

[tex] x = 11 [/tex]

(13x - 19)° + (17y + 5)° = 180° (linear pair)

[tex] 13x - 19 + 17y + 5 = 180 [/tex]

Plug in the value of x and solve for y

[tex] 13(11) - 19 + 17y + 5 = 180 [/tex]

[tex] 143 - 19 + 17y + 5 = 180 [/tex]

Collect like terms

[tex] 129 + 17y = 180 [/tex]

Subtract 129 from both sides

[tex] 129 + 17y - 129 = 180 - 129 [/tex]

[tex] 17y = 51 [/tex]

Divide both sides by 17

[tex] \frac{17y}{17} = \frac{51}{17} [/tex]

[tex] y = 3 [/tex]
