What is 15 percent of 1135? Also Explain how you came up with your solution and the actions you took.
Answer:
170.25
Step-by-step explanation:
15% x 1135
15/100 x 1135
170.25
Hello :D
10% of 1135 = 1135/10 = 113.5
5% of 1135 = 113.5/2 = 56.75
15% of 1135 = 113.5 + 56.75 = 170.25
Answer = 170.25

13) Rylee had a negative balance of $23 in her bank
account. Her cell phone bill charged this month's balance
of $56. What is Rylee's new balance?
Answer:
-$79
Step-by-step explanation:
If i read that correctly, Rylee had -$23 in her account.
Then, she was charged $56, meaning we have to subtract $56 from -$23. When we do -23 - 56, we get -79. Meaning, Rylee now has a balance of -$79.
Answer:
Step-by-step explanation:
The original price of Rylee’s groceries was $23.50. This money is leaving her bank account, so represent the amount with a negative sign:
-$23.50.
Rylee got a 20% discount on her purchase. In other words, she got 20% of her money back. The expression that represents the net change in her bank account is
-$23.50 – (-$23.50 × 0.2).
Further simplify the expression by factoring -$23.50 from both terms:
-$23.50 – (-$23.50 × 0.2)
=
-$23.50(1 – 0.2)
=
-$23.50(0.8).

Which translation vectors could have been used for the pair of figures?
select EACH correct answer
Answer:
The translation vector can be drawn on the coordinate grid or written as
\vec{v}=\langle a,b\rangle
v
=⟨a,b⟩
. For example, a translation vector that moves a figure
3
3
units right and
2
2
units down can be represented mathematically as
\vec{v}=\langle3,-2\rangle
v
=⟨3,−2⟩
, or graphically as
It doesn’t matter where the vector is positioned in the plane. In this figure, the vector starts at
(1,1)
(1,1)
and ends at
(4,-1)
(4,−1)
. But the initial point and terminal point of the vector are irrelevant. What matters is the length of the vector and the direction in which it points, so all you have to look at is how many units the vector moves in the
y
y
-direction and how many units the vector moves in the
x
x
-direction.

solve for x
|3x-8|+7=2
Answer:
No solution
Step-by-step explanation:
To solve first you need to isolate the absolute value sign. Do this by subtracting 7 from each side.
|3x-8| = -5Now an expression inside absolute value bars is set to a negative. Since absolute value makes terms and expressions positive, there is no x-value that could make this true. Therefore, there are no solutions.
[tex]\\ \tt\Rrightarrow |3x-8|+7=2[/tex]
[tex]\\ \tt\Rrightarrow |3x-8|=2-7[/tex]
[tex]\\ \tt\Rrightarrow |3x-8|=-5[/tex]
Because of absolute vale there is no solution

At the city museum, child admission is $5.20 and adult admission is $9.00. On Wednesday, four times as many adult tickets as child tickets were sold, for a total sales of $1359.60. How many child tickets were sold that day?
Answer:
33
Step-by-step explanation:
The amount of child tickets sold this day is x, when the amount of adult tickets is 4x
5.2x- the money from children, 9*4x=36x- the money from adults,
5.2x+36x= 1359.6
41.2x=1359.6
x=33- the amount of child tickets

5(1+2x)= 5 +10x =10x + 5
Answer:
Yes, they are eqivelant.
Step-by-step explanation:
5(1+2x) and 10x+5
The first step is to set them equal to each other, to see if they are equivelent.
5(1+2x) = 10x+5
Distribute the 5 to both terms in the parentheses by multiplying.
5(1) + 5(2x) = 10x +5
5 + 10x = 10x +5
The communative property of addition proves that these are equal.

50 = 2x
50/2 = 2x/2
x = 25
Answer:
Answer:
x = 25
explanation:
120 = 70 + 2x
120 - 70 = (70 - 70) + 2x

Image result for 44. Consider all rectangles with an area of 182 square feet. Let's Be the length of one side of such a rectangle a) Express the perimeter as a function of b) Use the graphing calculator to find the dimensions of the rectangle that has the least perimeter. What is the least perimeter?
Divide the area of the rectangle by the width in order to find the length of 14 feet. The perimeter is the sum of the side lengths, which in this case is 14 feet + 4 feet +14 feet + 4 feet, or 36 feet.
