Step-by-step explanation:
carla, bev, and ashley took their unit 2 math test. carla made an 80 and bev made a 75. what was ashleys score on the test if their average was 78.
Answer:
Ashley = 79
Step-by-step explanation:
[tex]Average=\frac{Carla+Bev+Ashley}{3}=78\\\\\frac{80+75+Ashley}{3}= 78 \\\\\frac{155+Ashley}{3}=78\\\\\frac{155+Ashley}{3}*\frac{3}{1} =78*3\\\\155+Ashley=234\\[/tex]
Subtract 155 from both sides;
Ashley = 79
which line is parallel to y=8x+11?
Answer:
Any line with a slope of 8 is parallel to y = 8x + 11. Some examples are:
y = 8x + 5
y = 8x + 1000
y = 8x +9
It doesn't matter what the y-intercept as long as the slope remains the same for a parallel line.
Answer:
Like the other person said, any line that has the same slope (8) will be parallel.

Answer:
The value of x is 3
Step-by-step explanation:
∵ Quadrilateral ABCD is congruent to quadrilateral JKLM
∴ AB = JK and BC = KL
∴ CD = LM and AD = JM
∵ BC = 8x + 7
∵ KL = 31
∵ BC = KL
→ Equate their right sides
∴ 8x + 7 = 31
→ Subtract 7 from both sides
∵ 8x + 7 - 7 = 31 - 7
∴ 8x = 24
→ Divide both sides by 8 to find x
∴ [tex]\frac{8x}{8}[/tex] = [tex]\frac{24}{8}[/tex]
∴ x = 3
∴ The value of x is 3
Which list is in order from least to greatest?
A. 2/3, 29%, 1/4 , 0.06
B. 2/3, 1/4, 29%, 0.06
C. 0.06, 1/4, 29%, 2/3
D. 1/4, 2/3, 0.06, 29%
Answer:
c
Step-by-step explanation:
2/3 converts to 0.66666667, 66.67%
1/4 converts to 0.25 , 25%
0.06 converts to 6%
So the order from least to greatest would be 0.06 , 1/4 , 29% , 2/3

Whats the answer help please
Need now thank you
Correct answer
Will give brainliest
Answer:The slope is 6/7
Step-by-step explanation:
when finding the slope you will need to move the 6x to the other side of the equation by subtracting which gives you 7y=14-6x and all that is left is to divide by 7 which gives y=14-6/7y
Answer:
6x - 7y = 14
⇔ 6x - 14 = 7y
⇔ 6/7.x - 2 = y
=> the slope is 6/7

How many factors of 100 are also multiples of 5?
Let us write the factors of 100. A factor of 100 can only be a multiple of five if it is divisible by five.
Divisibility rule of 5: A number can only be divisible by five if the ones digit of the number is a five or 0.Factors of 100 ⇒ numbers divisible by 100 ⇒ 1, 2, 4, 5, 10, 20, 25, 50, 100
When checking each factor of 100;
1 is not a multiple of 5 ⇔ not divisible by 5.2 is not a multiple of 5 ⇔ not divisible by 5.4 is not a multiple of 5 ⇔ not divisible by 5.5 is a multiple of 5 ⇔ divisible by 5.10 is a multiple of 5 ⇔ divisible by 5.20 is a multiple of 5 ⇔ divisible by 5.50 is a multiple of 5 ⇔ divisible by 5.100 is a multiple of 5 ⇔ divisible by 5.⇒ Five factors are multiples of 5.
Therefore, five factors of 100 are multiples of 5.
Please solve with elimination
5x + 9y =-5
3x -8y = -3
help I will give brainliest
please show work
Answer:
Step-by-step explanation:
5x+9y=-3 Multiply both sides by 8
40x+72y=-24
-53x-8y=-3 Multiply both sides by 9
-477x -72y= -27
sum the equations vertically to eliminate one variable
40x+72y= -24
-477x-72y= -27 (the y cancels out )
-477x =-51 (-24 + -27=-51)
-477x=-51 / -477 divide both sides by -477
x =51/437
5x 51/437=9y= -3 substitute the value of x
y= -174 /437
(x,y) = (51/437, -174/437)

The car travelled at the constant speed of 50.5 mph for 3 hours.
How far did the car travelled?
151.5 miles
Step-by-step explanation:
50.5 × 3 = 151.5
Answer:
151.5 Miles
Step-by-step explanation:
A constant speed means the speed was the same throughout the whole trip, also meaning there were no stops. So the answer is as simple as 50.5x3

Write the equation of the line that passes through the points (-8,-5) (5,−8)
Answer:
y=-3/13x-89/13
Step-by-step explanation:
m=y²-y¹/x²-x¹
m=(-8)-(-5)/5-(-8)
m=-3/13
y-y=m(x-x1)
y-(-8)=-3/13(x-5)
y+8= -3/13x+15/13
-8 -8
y=-3/13x-89/13

A number t multiplied by −4 is at least −25.
Answer:
[tex]t\leq 6.25[/tex] in decimal form
[tex]t\leq \frac{25}{4}[/tex] in fractional form
Step-by-step explanation:
-4 times a number t is greater than or equal to - 25. This is what they mean by at least.
[tex]-4t \geq -25[/tex]
Solve for t.
[tex]t\leq \frac{-25}{-4}[/tex] , we flip the inequality because we are dividing by a negative number.
[tex]t\leq 6.25[/tex]

A function graph of a line with two points (-3,-2) and (-1,2) with an x axis of negative five to five and a y axis of negative five to five
9514 1404 393
Answer:
y = 2x + 4
Step-by-step explanation:
You have the graph, so you can read the slope and y-intercept from it. The line goes up 2 units for each unit to the right, so the slope is ...
slope = rise/run = 2/1 = 2
The y-intercept is where the graph crosses the y-axis, at y=4.
The slope-intercept form of the equation for a line is ...
y = mx + b
where m is the slope (2) and b is the y-intercept (4). Your equation is ...
y = 2x +4

Answer:
2.) undefined slope 3.) zero slope (i'm not sure what 1 and 4 are, sorry!)
Step-by-step explanation:
undefined slope has the same x-coordinate and the denominator becomes 0. it also is a vertical line. for a zero slope, it has the same y-coordinate and the numerator is 0. this is a horizontal line. *this is my first response so if i am wrong, that is embarrassing*

Find the slope of the line that passes through (5, 13) and (9, 10).
Simplify your answer and write it as a proper fraction, improper fraction, or integer.
Answer:
The slope between (5, 13) and (9, 10) is:
[tex]m=-\frac{3}{4}[/tex]Step-by-step explanation:
Given the points
(5, 13)(9, 10)Finding the slope between (5, 13) and (9, 10)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{10-13}{9-5}[/tex]
[tex]m=-\frac{3}{4}[/tex]
Therefore, the slope between (5, 13) and (9, 10) is:
[tex]m=-\frac{3}{4}[/tex]Halla tres enteros impares consecutivos tales que 3 veces el entero del medio es 5 mas que la suma del primero y el tercero.
Responder:
3, 5, 7
Explicación paso a paso:
Sean enteros impares consecutivos:
x, x + 2, x + 4
3 (x + 2) = (x + x + 4) + 5
3x + 6 = (2x + 4 + 5)
3x + 6 = 2x + 9
3x - 2x = 9 - 6
x = 3
Por lo tanto,
x = 3; (x + 2) = 3 +2 = 5; x + 4 = .3 + 4 = 7

Jeff ordered 5 pizzas for his daughters birthday
party. Each pizza has 8 slices. At the party, 50%
of the pizzas were eaten. When the party was
over, Jeff ate 20% of what was left. How many
did Jeff eat?
Answer:
4 slices.
Step-by-step explanation:
5 x 8 = 40. 40 slices of pizza divded by 2 since 50% = 2.
20 slices, 20% of 20 slices or 20 in general is 4
