Answer:
a = -2
b = 7
Step-by-step explanation:
5a+3b=11
-2a+3=b
substitute for b:
5a + 3(-2a + 3) = 11
5a -6a + 9 = 11
-a = 2
a = -2
b = 7

Use the distributive property with factoring to find the equivalent expression. 24n + 32w = (3n + w)
Answer:
Step-by-step explanation:
24n + 32w = (3n + w)
We're asked to use distributive property, this means that we have to find a way that the given expression on the left hand side is equal to the given incomplete exresssion on the right hand side. In so doing, we're fulfilling the distributive property tag.
Given 3n, 3 factorises 24 into 8, and at the same time, factorises 32 into 4. Thus, we can then conclude that
24n + 32w = 8(3n + 4w)

. How many minutes is it from 23:35 today to 01:15 tomorrow?
A 100
B 110
C 120
D 130
E 140
Answer:
A (100)
Step-by-step explanation:
If 2 hours pass starting at 23:35 today, then tomorrow the time will be 1:35. The difference between 1:35 and 1:15 is 20 (minutes) Because there are 120 minutes in 2 hours (60 minutes per hour), This means we do 120 minutes minus 20 minutes. This gives us an answer is A, 100 :)

What is the volume of the figure?
Answer:
volume of a cone = [tex]\pi[/tex] [tex]r^{2}[/tex] h/3
[tex]\pi[/tex] = 22/7 or 3.14
r (radius) = 8 ft
h (height) = 16 ft
∴ volume = 22/7 * 8 * 8 * 16/3
= 3.14 * 64 * 16/3
= 1072.76190476 [tex]ft^{3}[/tex]
hope this answer helps you.....
please mark as brainliest ..... thank you....
Answer:
1072 ft³
Step-by-step explanation:
Formula we use,
→ V = πr²(h/3)
Now the volume of cone is,
→ πr²(h/3)
→ 3.14 × (8)² × (16/3)
→ 3.14 × 64 × 5.333
→ 200.96 × 5.333
→ 1072.33
→ ≈ 1072 ft³
Hence, volume is 1072 ft³.

y = 3x + 3
y = x − 1
Answer:
Step-by-step explanation:
Well you have to solve for X to find Y simplified.
Since both equations equal Y you can plug them together
3x+3=x-1
-x -x
2x+3=-1
-3 -3
2x=-4
Divide -4 by 2 and you get X = -2 then plug X into both equations and boom
y= -3

The line segment shown is translated down 4 units, what are the new coordinates of B?
(0.3)
Answer:
(0, - 1 )
Step-by-step explanation:
A translation down means subtracting 4 from the y- coordinate of the point, that is
B(0, 3 ) → B'(0, 3 - 4 ) → B'(0, - 1 )
Kameron's unicycle wheel has a spoke length of 16 inches.
16 in.
Approximately how many inches of ground does Kameron cover in 3 full rotations of the unicycle wheel? (Use 3.14 as an approximation of pi.)
Answer:
301.44 inches
Step-by-step explanation:
The spoke is from the center of the wheel to the edge, so its length is the radius, or 16 inches.
You want to find the distance that one rotation will take you, so you need the wheel's circumference.
Circumference = 2πr
2 x 3.14 x 16 = 100.48
100.48 inches is the distance of only 1 full rotation, so you just need to multiply 100.48 by 3 to get the distance of 3 rotations.
100.48 x 3 = 301.44

A toy company has 6 different heights of its best-selling action figure, labeled versions 1 through 6. Each version is modeled from clay molding of the action figure. Version 1 is 125% taller than the clay molding of the action figure. The heights of action figure versions 2 through 6 are each 125% taller than the previous version of the action figure. The clay molding of the action figure is 4 inches tall. Which function can be used to find the height in inches of each version of action figure, where 1 ≤ v ≤ 6?
h(v) = 1.25(v+ 4)
h(v) = 4(1.25)v
h(v) = 1.25(4)v
h(v) = 4(v + 1.25)

set up :
6x + 115 = 7x +5 (subtract 6x from both sides)
115 = x +5 (subtract 5 from both sides)
110 = x (your answer)
CHECK:
6(110) + 115 = 775
7(110) + 5 = 775
A bag of candy contains 5 different types of colored candies; red, green, blue, yellow, and orange. According to the manufacturer, bags should contain an equal number of each color. Students in a statistics class decided to use a chi-square procedure to test the manufacturer’s claim. They opened a bag of candy and recorded the number of candies of each color. The results are shown in the following table.

A bag of candy contains 5 different types of colored candies; red, green, blue, yellow, and orange. Students in a statistics class decided to use a chi-square procedure to test the manufacturer’s claim.
They opened a bag of candy and recorded the number of candies of each color. The results are shown in the following table-
Red Green Blue Yellow Orange
17 24 20 25 14
The average of the all the values is 20.
Now, according to the manufacturer, bags should contain an equal number of each color. Thus, the expected value for the bag of candy are,
Red Green Blue Yellow Orange
20 20 20 20 20
Form, the above formula the color which has less values of observed, and more value of expected, contributes most to the chi-square test statistic.
Here, the orange color has the less value of observed frequency. Therefore, the color which contributes most to the chi-square test statistic for the bag of candy is orange color.

Given f (x) = 5x2 and g(x) = 2x + 3, find f(g(-4))
Answer:
125
Step-by-step explanation:
Given
f(x) = 5x²
g(x) = 2x + 3
Now
g(-4) = 2 * (- 4) + 3
= - 8 + 3
= - 5
Also
f(g(-4)) = f( -5)
= 5 * ( -5)²
= 5 * 25
= 125
