If 40x = 400, then A. x equals 100. B. x equals 10. C. I equals 4. O D. x equals 1. E. requals 0 ).
Answer:
B- x= 10
Step-by-step explanation:
40x=400 -> 40 x 10= 400
The value of x in the expression 40x = 400 by combining like terms would be 10. Hence, option B is true.
Given that,
The expression is,
40x = 400
Used the concept of expression by combining like terms.
Here, the expression is,
40x = 400
Divide both sides by 40,
x = 400/40
Therefore, the solution of x is,
x = 10
So, Option B is true.

find the measure of angle J .will mark brainiest
Answer:
<J=51°
Step-by-step explanation:
3x-2+4x-9+3x-9=180
10x-20=180
10x=200
x=20
<J=3x-9=3(20)-9=60-9=51°
Answer: Angle J = 51°
Step-by-step explanation: All angles add up to 180° in a triangle, so add every angle and set it equal to 180°.
(3x - 2) + (3x - 9) + (4x - 9) = 180
Add like terms:
10x - 20 = 180
Add 20 to both sides:
10x = 200
Divide both sides by 10:
x = 20
Now, plug x into angle J:
3(20) - 9
60 - 9
51
Angle J = 51°

How do you write 1.65x10^8: 2x10^3 in scientific notation?
I'm guessing you're talking about the ratio,
(1.65 x 10⁸) / (2 x 10³)
You can cancel the lowest power of 10:
(1.65 x 10⁸) / (2 x 10³) = (1.65 x 10⁵) / 2
Divide 1.65 in half to get 0.825. So we have
(1.65 x 10⁸) / (2 x 10³) = 0.825 x 10⁵
Move the decimal point to the right, which involves multiplying by a factor of 10 which is taken from 10⁵, so we end up with
(1.65 x 10⁸) / (2 x 10³) = 8.25 x 10⁴

0.99/8=0.123
1.47/12=0.1225
The second option is better since its 0.005 less than the first option.
B. Again, divide both options.
0.77/16=0.04125
1.50/31=0.04838
Second option because it is 0.00713 cents cheaper.
C. 1.77/3=0.59
1.79/5= 0.36
Second option is .23 cents cheaper than the first option.

What is a number system?A numeral system is a way of writing numbers; it's a way of mathematically notating a collection of numbers by utilizing a consistent set of digits or other symbols. In several numeral systems, the same set of symbols may represent various numbers.
Given that Salma must choose a number between 55 and 101 that is a multiple of 2, 8, and 16.
To calculate the numbers between 55 and 101 and are the multiple of 2,8, and 16. Get the multiple of 16 which will be the multiple of 8 and 2.
80 and 96 is the multiple of 16 and also of 8 and 2.
80 = 8 x 10 = 80
80 = 16 x 5 = 80
80 = 40 x 2 = 80
96 = 16 x 6 = 96
96 = 48 x 2 = 96
96 = 8 x 12 = 96
Therefore, the numbers between 51 and 101 and multiples of 2,8, and 16 are 80 and 96.

At a fabric store, fabrics are sold by the yard. A dressmaker spent $36.35 on 4.25 yards of silk and cotton fabrics for a dress. Silk is $16.90 per yard and cotton is $4 per yard.
Find the solution of the system of equations. Explain or show your reasoning
{x+y=4.25} ; {16.90x+4y=36.35}
Answer:
The number of yards of silk = x = 1.5 yards
The number of yards of cotton = y = 2.75yards
Step-by-step explanation:
At a fabric store, fabrics are sold by the yard. A dressmaker spent $36.35 on 4.25 yards of silk and cotton fabrics for a dress. Silk is $16.90 per yard and cotton is $4 per yard.
Find the solution of the system of equations. Explain or show your reasoning
{x+y=4.25} ; {16.90x+4y=36.35}
Let the number of yards of silk = x
The number of yards of cotton = y
We are given the system of equations:
{x+y=4.25} ......Equation 1
x = 4.25 - y
{16.90x+4y=36.35}....... Equation 2
4.25 - y for x in Equation 2
16.90(4.25 - y) + 4y = 36.35
71.825 - 16.90y + 4y = 36.35
71.825 - 36.35 = 16.90 - 4y
35.475 = 12.90y
y = 35.475/12.90
y = 2.75 yards.
The number of yards of cotton = y
{x+y=4.25} ......Equation 1
x = 4.25 - y
x = 4.25 - 2.75
x = 1.5 yards
The number of yards of silk = x = 1.5 yards
The yards of silk bought is 1.49 yards and the yard of cotton bought is 2.76 yards.
The two equations are known as simultaneous equation. They would be solved using elimination method.
x + y = 4.25 equation 1
16.90x + 4y = 36.25 equation 2
where:
x = yards of silk bought
y = yards of cotton bought
In order to determine the value of x, multiply equation 1 by 4.
4x + 4y = 17 equation 3
Subtract equation 3 from 2
19.25 = 12.90x
Divide both sides of the equation by 12.90
x = 1.49 yards
In order to determine the value of y, substitute for x in equation 1
1.49 + y = 4.25
y = 4.25 - 1.49
y = 2.76 yards
