E none of these
Answer:
E non of the above
Step-by-step explanation:
To get the original number you multiply 88 by 4
Then you add 80, 85 and 95 and then minus it from the original number
You should end up with 352 minus 260
Therefore the answer would be 92 and not a given answer so your answer is e: none of the above

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}
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

Leo has $28 to spend on pencils and paper for a school. Pencils cost $0.50 each and paper cost $1.50 each. Using x for pencils, and y for paper, write an inequality that represents what Leo can buy.
Answer:
Please mark Brainliest if helpful...
0.5x+1.5y[tex]\leq[/tex]28
Step-by-step explanation:
X is the number of pencils, so multiply the price of one pencil by the number of them to get the total price of pencils-0.5xY is the number of paper, so multiply the price of one paper by the number of them to get the total price of paper-1.5yLeo has $28, so he can either spend $28 or less on pencil and paper, which means that his total cost should be less than or equal to 281,2,1,10,1,50,1 what is the next number

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.

8sin(8x)+9=3
Need solutions
Answer:
Simplifying
8sin(8x) + 9 = 3
Remove parenthesis around (8x)
8ins * 8x + 9 = 3
Reorder the terms for easier multiplication:
8 * 8ins * x + 9 = 3
Multiply 8 * 8
64ins * x + 9 = 3
Multiply ins * x
64insx + 9 = 3
Reorder the terms:
9 + 64insx = 3
Solving
9 + 64insx = 3
Solving for variable 'i'.
Move all terms containing i to the left, all other terms to the right.
Add '-9' to each side of the equation.
9 + -9 + 64insx = 3 + -9
Combine like terms: 9 + -9 = 0
0 + 64insx = 3 + -9
64insx = 3 + -9
Combine like terms: 3 + -9 = -6
64insx = -6
Divide each side by '64nsx'.
i = -0.09375n-1s-1x-1
