Answer:
51 and -27
Step-by-step explanation:
The sum of two numbers is 24 and their difference is 78. What are the two numbers? Let's start by calling the two numbers we are looking for x and y.
The sum of x and y is 24. In other words, x plus y equals 24 and can be written as equation A:
x + y = 24
The difference between x and y is 78. In other words, x minus y equals 78 and can be written as equation B:
x - y = 78
Now solve equation B for x to get the revised equation B:
x - y = 78
x = 78 + y
Then substitute x in equation A from the revised equation B and then solve for y:
x + y = 24
78 + y + y = 24
78 + 2y = 24
2y = -54
y = -27
Now we know y is -27. Which means that we can substitute y for -27 in equation A and solve for x:
x + y = 24
x + -27 = 24
X = 51
Summary: The sum of two numbers is 24 and their difference is 78. What are the two numbers? Answer: 51 and -27 as proven here:
Sum: 51 + -27 = 24
Difference: 51 - -27 = 78
Answer:
The numbers are 27 and 51
Explanation
x - y = 24
x + y = 78
Add together the equations
2x = 102
x = 51
Put into equation
51 - y = 24
27 = y
In the school competition jenny bounced a ball 150 times in 3 minutes. Express her bouncing rate in its simplest form
Answer:
Jenny bounced the ball 150 times She did that over an interval of 3 minutes To express rate of change over an interval you do [tex] \frac{change \: in \: motion}{change \: in \: time} [/tex]So you get [tex] \frac{150}{30} = 50 \: bounces \: per \: minute[/tex]Please rate positively and give brainlist3^38 - 3^37 =2/3^x
answer
Step-by-step explanation:
3³⁸ - 3³⁷
= 3³⁷(3 - 1)
= 2 * 3³⁷
= 2 / [3^(-37)].
Hence x = -37.

Answer:
5a. ΔGKM ~ ΔSPM by SAS
b. ΔABC is not similar to ΔDEF
6. The missing side is 2[tex]\sqrt{11}[/tex]
Step-by-step explanation:
5a. Yes, the triangles are similar.
<KMG ≅ <PMS (vertically opposite angles)
ΔGKM ~ ΔSPM by SAS
Ratio: GM:SM OR KM:PM
3:6 OR 2:4
1:2 OR 1:2
Ratio: 1:2
b. No, the triangles are not similar
ΔABC is not similar to ΔDEF
Ratio: AC:DF OR AB:DE
4:6 OR 2:4.5
1:1.5 ≠ 1:2.25
Ratio: not similar
6. let the missing side of the triangle be represented by x. Since the triangle is a right angled triangle, then applying the Pythagoras theorem we have;
[tex]/hyp/^{2}[/tex] = [tex]/adj 1/^{2}[/tex] + [tex]/adj2/^{2}[/tex]
[tex]/12/^{2}[/tex] = [tex]x^{2}[/tex] + [tex]/10/^{2}[/tex]
144 = [tex]x^{2}[/tex] + 100
[tex]x^{2}[/tex] = 144 - 100
= 44
x = [tex]\sqrt{44}[/tex]
= [tex]\sqrt{4 *11}[/tex]
= 2[tex]\sqrt{11}[/tex]
x = 2[tex]\sqrt{11}[/tex]
The missing side is 2[tex]\sqrt{11}[/tex].

Step-by-step explanation:
If there are 328 million people and 228 thousand become infected each day, how long will it take for all to be infected?
Answer:
1438.6 days
Step-by-step explanation:
We are told in the above question that:
228,000 people get infected per day. Hence, how long it would take for 328,000,000 people to be infected is calculated as:
228,000 people = 1 day
328,000,000 people = x days
Cross Multiply
228,000 people × x days = 328,000,000 people × 1 day
x days = 328,000,000 people × 1 day/228,000 people
x days = 1438.5964912 days
Approximately = 1438.6 days
Therefore, it would take 1438.6 days for 328,000,000 people to be infected.

The change in the value of stock is represented by the rational number -5.90. Describe, in words, what this means.
Answer:
DEFINITION of Value Change
Value change is an adjustment made to a stock's price to reflect the number of outstanding stock shares issued and currently held by investors. A value change allows the group of stocks to be equally weighted and, therefore, more easily evaluated. Since the number of shares held by investors changes daily, this number can be updated daily to reflect the changes.

If f(x)= x2+2x-10, what id f(-2)
g(x)= 3x-5
h(x)=2/2x+3
write h(g(x)) as an expression terms of x
Answer: h(g(x))= 2/6x-7
Step-by-step explanation:
1.h(g(x))= 2/(g(x))+3
2.g(x)= 3x-5
h(g(x))= 2/2(3x-5)+3
=2/6x-10+3
=2/6x-7
A food truck is selling 2 burritos for $5.
Which of the following equations models the relationship between burritos and dollars?
Given that,
A food truck is selling 2 burritos for $5.
Solution,
We need to find the relationship between burritos and dollars.
2 burritos = $5
To find the value of 1 burrito. Divide 5 by 2 as follows :
[tex]1\ \text{burrito}=$\dfrac{5}{2}\\\\1\ \text{burrito}=$2.5[/tex]
Hence, the relation between burritos and dollars is " [tex]1\ \text{burrito}=$2.5[/tex]"
Hey I neee help with this I don’t understand for number 1 it’s w=? For number 2 it’s w=75 and for number 3 it’s w=26. Pls I need help it’s due in 10 minutes I’ll mark brainliest possibly.
Answer:
1. W = 50 ft
2. L = 110 m
3. L = 61 m
Step-by-step explanation:
Area of a Rectangle
Given a rectangle of width W and length L, its area is calculated by the formula:
A = W.L
We are given three rectangle-shaped figures and are required to find different measures as explained below.
1. Length L=94 ft, Area = 4,700 square ft
We'll find the width by solving for W:
[tex]\displaystyle W = \frac{A}{L}[/tex]
[tex]\displaystyle W = \frac{4,700}{94}[/tex]
W = 50 ft
2. A=8,250 square m, W=75 m
We'll find the length by solving for L:
[tex]\displaystyle L = \frac{A}{W}[/tex]
[tex]\displaystyle L = \frac{8,250}{75}[/tex]
L = 110 m
3. A=1,586 square m, W=26 m
We'll find the length by solving for L:
[tex]\displaystyle L = \frac{A}{W}[/tex]
[tex]\displaystyle L = \frac{1,586}{26}[/tex]
L = 61 m

Answer:
The true statement is h < k ⇒ (3)
Step-by-step explanation:
∵ The equation of the graph is y = [tex]\sqrt{x+h}[/tex] + k
∵ (-h, k) are the coordinates of its vertex point
∵ -h is the x-coordinate of the vertex point
∵ x-coordinate of the vertex point is -3
∴ -h = -3
→ Divide both sides by -1
∴ h = 3
∵ k is the y-coordinate of the vertex point
∵ y-coordinate of the vertex point is 4
∴ k = 4
∵ 3 < 4
→ That means h is smaller than k
∴ h < k
∴ The true statement is h < k

What is JK? please explain/show your work on how you got your answer
Answer:
JK = 20 mStep-by-step explanation:
A line segment that connects two midpoints of the sides of a triangle is called a midsegment.A triangle midsegment is parallel to the third side of the triangle and is half of the length of the third side.Point J is midpoint of side HI as HJ = JI
Point K is midpoint of side GI as GK = KI
JK is midsegment as connects the midpoints of the sides
JK = 1/2HG as per property of midsegment
6x - 4 = 10x/26x - 4 = 5x6x - 5x = 4x = 4JK = 6x - 4 = 6*4 - 4 = 24 - 4 = 20 m
Answer:
[tex]JK=20m[/tex]
Step-by-step explanation:
It is given in the diagram that IJ = JH and IK = KG. Therefore, by the definition of a midpoint, we know that J and K are the midpoints of segments IH and IG respectively. Then, it can be concluded that JK is a midsegment by the definition of a midsegment. The Midsegment Theorem states that a midsegment connecting the midpoints of two sides of a triangle is parallel and half of the length of the third side. Thus, we know that JK is half of HG. Now, we can set up the following equation to solve for x:
[tex]JK = \frac{1}{2}HG\\6x-4=\frac{1}{2}(10x)[/tex]
Solving for x, we get:
[tex]6x-4=\frac{1}{2}(10x)\\6x-4=5x\\x-4=0\\x=4[/tex]
Therefore, [tex]JK = 6x - 4 = 6(4) - 4=24-4=20 m[/tex].
Hope this helps!
