Answer:

(4,-1)

Step-by-step explanation:

x-4y=8

-4y=-x+8

y=1/4x-2

The solution to the equation x - 4y = 8 is an ordered pair (4,-1).

A solution to an equation is a number that can be substituted for the variable to provide a true number statement.

The equation is given in the question, as follows:

x - 4y = 8

To determine the ordered pair (x,y) of the solution, substitute the value of x = 4 in the equation, and solve for y:

4 - 4y = 8

- 4y = 8 - 4

- 4y = 4

y = - 4/4

Divided by -4 into both sides of the equation, we get

y = - 1

Thus, the solution to the equation is an ordered pair (4,-1).

Answer:3/3/4

Step-by-step explanation:

Answer:

There are three more angles with the same measure. A pair of corresponding angles and a pair of vertical angles.

Step-by-step explanation:

==========================================================

Explanation:

I recommend drawing out a diagram as shown below. Angle 1 is 58 degrees.

Angle 3 is also 58 since the two angles are congruent vertical angles.

Angle 5 is equal to angle 1 due to them being corresponding angles (this only works if the lines are parallel)

Angle 8 is congruent to angle 5, for similar reasonings with angle 3 above.

So that means we have three additional angles that are 58 degrees: angle 3, angle 5, angle 8

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

The rest of the angles are 122 as the diagram shows. We have four angles that make up the rest of the angles. Angle 2 and angle 1 add to 180, so

x+y = 180

58+y = 180

y = 180-58

y = 122

And you'll find the other unknown angles fit this pattern as well. Or you could use corresponding angles and vertical angles to fill out the rest of the diagram.

Step-by-step explanation:

Evaluate 5 x + x/2 - 29.4 where x = 11/5:

5 x + x/2 - 29.4 = 5×11/5 - 29.4 + 1/2×11/5

Hint: | Express 5×11/5 as a single fraction.

5×11/5 = (5×11)/5:

(5×11)/5 - 29.4 + (11/5)/2

Hint: | Express (11/5)/2 as a single fraction.

(11/5)/2 = 11/(2×5):

(5×11)/5 - 29.4 + 11/(2×5)

Hint: | Cancel common terms in the numerator and denominator of (5×11)/5.

(5×11)/5 = 5/5×11 = 11:

11 - 29.4 + 11/(2×5)

Hint: | Multiply 2 and 5 together.

2×5 = 10:

11 - 29.4 + 11/10

Hint: | Approximate 11/10.

11/10≈1.1:

11 - 29.4 + 1.1

Hint: | Evaluate 11 + 1.1 using long addition.

| 1 | 1. | 0

+ | | 1. | 1

| 1 | 2. | 1:

12.1 - 29.4

Hint: | Factor out a negative sign in 12.1 - 29.4 in order to subtract.

12.1 - 29.4 = -(29.4 - 12.1):

-(29.4 - 12.1)

Hint: | Subtract 12.1` from 29.4`.

Step-by-step explanation:

brainliest please

Answer:

Higher

Step-by-step explanation:

16.98 + 9.29 = 26.27 < 27.00

26.27 is rounded to 26.10 or 26.00 so Ed's estimate is higher

Answer:

Part A = the middle one

Part B = 4 days

Step-by-step explanation:

1,300 / 4 = 325

325 x 4 = 1,300

Inequality to represent number of days is 325d ≥ 1300.

Number of days to travel at least 1300 is 4.

An inequality is a mathematical expression in which both sides are not equal. Unlike equations, inequalities compare two values. Equal signs between are replaced by less than (or less than), greater than (or greater than), or not equals signs.

Given,

Family drives 325 miles per day

To travel at least 1300 miles

Let number of days be d

then

325d ≥ 1300

Dividing with 325 on both sides

d ≥ 1300/325

d ≥ 4

Hence, 325d ≥ 1300 is the inequality that represents number of days d to travel at least. 4 days is the least number of days.

Answer:

9 containers

Step-by-step explanation:

Since Wendy wants to divide the 10 [tex]\frac{1}{2}[/tex] pounds of the potato salad into 1 [tex]\frac{1}{4}[/tex] pounds for each container, You just divide 10 [tex]\frac{1}{2}[/tex] by 1 [tex]\frac{1}{4}[/tex] using the following method:

Convert 10 [tex]\frac{1}{2}[/tex] into an improper fraction:

[tex]\frac{21}{2}[/tex]

Convert 1 [tex]\frac{1}{4}[/tex] into an improper fraction:

[tex]\frac{5}{4}[/tex]

Then finally divide [tex]\frac{21}{2}[/tex] by  [tex]\frac{5}{4}[/tex] :

[tex]\frac{21}{2}[/tex] ÷ [tex]\frac{5}{4}[/tex]

This is the same as [tex]\frac{21}{2}[/tex] times the reciprocal of [tex]\frac{5}{4}[/tex]:

[tex]\frac{21}{2}[/tex] × [tex]\frac{4}{5}[/tex] = [tex]\frac{42}{5}[/tex] = 8.4

Since we cannot have 8.4 containers, we round it up to 9 containers, because for 8 containers, there will still be some pounds of potato salad left.

you will run 1.6 meters in one second.
