O 1/5
Answer:
1/2
Step-by-step explanation:
So we multiply 2 by 6, and get 12.
Then we multiply 1 by 3, and get 3.
Next we give both terms new denominators
So now our fractions look like this:
12/18-3/18
Since our denominators match, we can subtract the numerators.
12 − 3 = 9
So the answer is:
9/18
So we reduce it:
9/18divided by 3=3/6
so since it’s equivalent we reduce it again
3/6divided by 3 which equals 1/2
and that’s our final answer 1/2
I hoped that this helps :)
The production cost to make 10 shirts is modeled by the expression 1.By + 5.5, where y represents the number of meters of fabric needed to make the shirts. Which
expression represents the production cost for one shirt?
A.0.18y +0.55
B.0.18y +5.5
C.1.8y +0.55
D.18y +55y
Answer:
The answer is 0.18y+5.5
Step-by-step explanation:
because the only thing you had to do is move the decimal.
The expression which represents the production cost for one shirt is, 0.18y +0.55. So Option A is correct
What are expressions?An expression is a sentence with at least two numbers or variables having mathematical operation. Math operations can be addition, subtraction, multiplication, division.
For example, 2x+3
Given that,
The production cost to make 10 shirts is modeled by the expression,
Total Cost = 1.8y + 5.5,
where y represents the number of meters of fabric needed to make the shirts
So, for one shirt cost,
Cost of 1 shirt = Total Cost/10
= 1.8y + 5.5/10
= 0.18y + 0.55
Thus, the expression is 0.18y + 0.55

Answer:
$27.92
Step-by-step explanation:
To find the sale price, multiply the original price by 0.4:
69.8(0.4)
= 27.92
So, the sale price is $27.92
The amount for sale is $27.92.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
Original Price = $69.80
And, Percent of Discount = 60%
Hence, Sale price is find as;
Sale price = $69.80 - 60% of 69.80
= $69.8 - 60/100 × 69.80
= $69.80 - $41.88
= $27.92

2.25(a+1.3)=20.7 What is the value of a?
Answer:
a=7.9
Step-by-step explanation:
2.25(a+1.3)=20.7 *Distribute (multiply) the 2.25 throughout the parenthesis
2.25a+2.925=20.7 *Subtract 2.925 from both sides
2.25a=17.775 *DIvide by 2.25
a=7.9
The solution of the equation 2.25 (a + 1.3) = 20.7 will be 7.9.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The equation is given below.
2.25 (a + 1.3) = 20.7
Simplify the equation, then we have
2.25 (a + 1.3) = 20.7
(a + 1.3) = 9.20
a = 9.20 - 1.3
a = 7.9
The solution of equation 2.25 (a + 1.3) = 20.7 will be 7.9.
