Step-by-step explanation:
4 x 2 =8
3 x 2= 6
Answer:
[tex]x = 6[/tex]
Step-by-step explanation:
What I would do in this case is cross multiply, although there are other strategies. I will explain cross multiplication here. In cross multiplication you multiply the denominater and numerator of different fractions on each side of the equal sign. So for this problem you would multiply 4 and X, denominator of the first number and numerator of the second. Then you would multiply the numerator from the first fraction, 3, and denominator from the second, 8.
[tex]4 \times x = 4x \\ 3 \times 8 = 24 \\ \\ so \: 4x = 24[/tex]
Now we can solve for x.
[tex]4x = 24 \\ \div 4 \\ x = 6[/tex]

Explain step by step how to do 10.25 x .15.
Answer:
1.5375
Step-by-step explanation:
Multiply without the decimal points, then put the decimal point in the final answer
1025 x 15 = 15375
....
10.25 has TWO decimal places
0.15 has TWO decimal places
Therefore, when you multiply with the decimal points (10.25 x 0.15), the answer should have FOUR total decimal places.
So the answer is 1.5375

I need help this is due today and i just need this one question. How can you find the unit rate or constant of proportionality for a relationship represented in a graph. I will give Brainleist.
Answer:
If the rate of change is yx , then so is the constant of proportionality. To simplify things, we set yx=k , where k represents the constant of proportionality. If you solve a yx=k equation for y, (like this: y=kx), it is called a direct variation equation.

Use all four operations and at least one exponent to write an expression that has a value of 100.
Answer: 5 to the 2 power x4+100 divide by 2
Step-by-step explanation:
The expression that has a value of 100 is 5²×4 + 100/2 - 50 and has all four operations and at least one exponent.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
It is given that:
Use all four operations and at least one exponent to write an expression that has a value of 100.
The value of the expression = 100
As we know,
In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.
The number expression will be:
5²×4 + 100/2 - 50
Thus, the expression that has a value of 100 is 5²×4 + 100/2 - 50 and has all four operations and at least one exponent.

The equation below describes a proportional relationship between x and y. What is the constant of proportionality? Use pencil and paper. Explain why your answer is called the "constant of proportionality." y=7.19x PLEASE HURRY IM TIMED!!
Answer:
The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other. Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.
