find the ordered pair (x,y) that is a solution to the equation
x-4y=8
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).
What is the solution to the equation?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).

Wendy has 10 ½ pounds of potato salad. She wants to divide the potato salad into containers, each of which holds 1 ¼ pounds. How many containers does she need? Show your work and answer in a complete sentence.
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.

zach is 4 years older than twice his sister maya's age. zach is 28 years old.
which expression would you use to represent zach's age?
Answer:
Lets take:
Z - Zach
M - Maya
Now forming the equation:
Z = 2M+4
Z = 28
Solving:
2M+4 = 28
2M = 24
M = 12
Zach's age is 28; whereas Maya's age is 12.
Answer:
2m + 4 = 28
Step-by-step explanation:
Let m be Maya's age
4 years older than twice his sister Maya's age = 2m + 4 If "4 years older than twice his sister Maya's age" and "Zach is 28 years old" are equal, then this is how you'd write it: 2m + 4 = 28I hope this helps!

A pair of parallel lines is cut by a transversal. One of the angles formed measures 58°. Which statements about the other seven angles formed are true?
There are three more angles with the same measure.
All the other angles have the same measure.
The rest of the angles measure 122°.
Only three of the angles measure 122°.
Four of the angles measure 122°.
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.

A family drives 325 miles per day during a road trip.

Select the correct symbol to complete the inequality that represents how many days, d, the family must drive to travel at least 1,300 miles.
325d 1,300
00:00
Part B
For how many days must the family drive to travel at least 1,300 miles? Enter your answer in the box.
days
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.
What is inequality?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.
