Answer:
lets say you where multiplying by 2
2+ 2=4 so that would mean 2x2 is 4
and so on and so on
Step-by-step explanation:
ok so an equation like 2x3 is the same as 2+2+2.
Jacie is serving steak and chicken she wants to have at least 20 pounds of meat. Steak is $8 per pound and chicken is $4 per pound . Jacie wants to spend at most 120 dollarss on meat
Answer:
She can get 10 pounds of steak and 10 pounds of chicken.
Step-by-step explanation:
As Jacie wants to have at least 20 pounds of meat, you can write the following equation:
x+y=20, where
x refers to the pounds of steak
y refers to the pounds of chicken
Also, since the statement indicate that the steak is $8 per pound and chicken is $4 per pound and Jacie wants to spend at most 120 dollars on meat, you can write the following equation:
8x+4y=120
So, you have the following equations:
x+y=20 (1)
8x+4y=120 (2)
Now, you can solve for x in (1):
x=20-y (3)
Then, you can replace (3) in (2) and solve for y:
8(20-y)+4y=120
160-8y+4y=120
160-120=8y-4y
40=4y
y=40/4
y=10
Finally, you can relace the value of y in (3) to find x:
x=20-y
x=20-10
x=10
According to this, the answer is that she can get 10 pounds of steak and 10 pounds of chicken.

What is the slope of the line shown on the graph?
Answer:
Step-by-step explanation:
The slope, m, can be determined using any two points, and slope is defined as
m=(y2-y1)/(x2-x1), I’ll use (0,0) and (5,-1)
m=(-1-0)/(5-0)
m=-1/5

Answer:
The answer is B. [tex]3\frac{1}{3} ft.[/tex]
Step-by-step explanation:
It states that the figures in the pair are similar
When you multiply 5*8 it gives you 40 on the first angle
If the figures are similar then the other angle will equal 40.
So we need to find out which number that is multiplied by 12 that will give you 40.
If we multiply [tex]12*3\frac{1}{3}[/tex], it should give you 40.
Convert The mixed number into a improper fraction:
3 1/3=3*3+1/3
=10/3
Convert the element into a fraction:
12/1*10/3
Factor the number:
3*4/1=10/3
Cross - cancel the common factor: 3
4/1*10/1
Apply the fraction rule:
4*10/1*1
Multiply the numbers: 4*10=40
=40/1*1
Multiply the numbers: 1*1=1
=40/1
Apply the Fraction rule:
=40

Write two different equations to describe each situation. a) You buy 3 identical shirts and 2 identical pairs of socks and spend $38.
Answer:
3x + 2y = 38, 3a + 2b = 38
Step-by-step explanation:
An equation may be defined as a statement that shows two mathematical expressions to be equal. It is to equate one thing to another thing.
In the context, two different equations for the situations are :
i). Let the shirt be represented by x
And the socks be represented by y
Therefore, according to the question,
3x + 2y = 38
ii). Let the shirt be represented by a
And the socks be represented by b
Therefore, according to the question,
3a + 2b = 38
You told your friend that you could eat 3/5 of a large pizza. If you only ate 1/2 of what you said you could eat, what fraction of a large pizza did you eat?
Answer:
3/10
Step-by-step explanation:
3/5 is equal to 6/10, and half of 6/10 is 3/10
Answer:
3/10
Step-by-step explanation:
Amount of pizza u told= 3/5
Amout u could eat of wht u told = 1/2
Amount u could eat of pizza = 3/5 x 1/2 = 3/10

Determine the probability of a z-score to the right of a z-score of -1.25. P\left(z>-1.25\right)P(z>−1.25)
Answer:
0.894
Step-by-step explanation:
This would be the area under the standard normal curve to the right of z = -1.25. There are various ways in which we can calculate this area. I will use a TI-83Plus calculator, which features the necessary normalcdf( function:
normalcdf(-1.25, 1000) = 0.894
So: the area under the standard normal curve to the right of z = -1.25 is 0.894. This area also represents the desired probability.

Let's multiply the first equation by 2 and the second equation by 3, in order to have the same coefficient on y.
-8x+6y=18
15x-6y=87
Add these two equations together to eliminate y.
7x=105
x=15
Now, plug in x, to find y.
5(15)-2y=29
75-2y=29
-2y=-46
y=23

Express the following in the form 10where n is an integer 10−8 × 10−6
Given:
The given expression is:
[tex]10^{-8}\times 10^{-6}[/tex]
To find:
The expression in the form of [tex]10^{-n}[/tex].
Solution:
We have,
[tex]10^{-8}\times 10^{-6}[/tex]
It can be written as
[tex]10^{-8}\times 10^{-6}=10^{-8+(-6)}[/tex] [tex][\because a^ma^n=a^{m+n}][/tex]
[tex]10^{-8}\times 10^{-6}=10^{-8-6}[/tex]
[tex]10^{-8}\times 10^{-6}=10^{-14}[/tex]
Therefore, the required value is [tex]10^{-14}[/tex].

Christina says that if she multiplies 23×25, her product will automatically be less than 23 because 25 is less than 1, meaning the product will only be a part of 23. Is Christina correct?
Answer:
Christina is incorrect.
Step-by-step explanation:
Since we are multiplying and our numbers are larger than 1, we know our product will be large. Your answer will be 575 :)

find the measure of angle 1
Answer:
44°
Step-by-step explanation:
8x - 4 = 6x + 8 (This is because they are corresponding angles)
8x - 6x = 8 + 4
2x = 12
x = 12 ÷ 2
x = 6
6x + 8 = angle 1 (Vertically opposite angles are equal)
Substitute the value of x in the equation '6x +8' to get the size of the angle.
6 × 6 + 8
36 + 8 = 44°
Angle 1 = 44°
